Elsner, Regina Marie. "Knowledge, attitudes, and opinions about human-wildlife conflicts held by community leaders in Virginia." Thesis, Virginia Tech, 2008. http://hdl.handle.net/10919/34385.
Full textAbstract:
Using a mail survey, I questioned 490 representatives of local government (i.e., elected officials, administrative officials, animal control officers, and county Cooperative Extension agents) about their understanding of human-wildlife conflicts in their communities, and their receptivity to participating in co-management partnerships with regulatory agencies. Response rates for the mail survey of these four populations ranged from 25.2% to 75.9%. Knowledge of and perceptions about human-wildlife conflicts varied among leader subpopulations, as did their assessment of risks associated with and prioritization of human-wildlife conflicts. Animal control and Extension personnel displayed greater knowledge about wildlife, expressed greater concern about potential risks, and assigned higher priority to human-wildlife conflicts in their community.
Respondents indicated that wildlife complaints are being received from constituents in their community, but questions exist over who is responsible for managing these conflicts. Most respondents indicated a willingness to become involved in conflict resolution, but indicated less willingness for local government to take on a leadership role. Respondents could identify potential partners valuable to resolving human-wildlife conflicts, but they demonstrated uncertainty about the specific roles and responsibilities of these outside agencies (e.g., Virginia Department of Game and Inland Fisheries). Respondents identified important potential impediments (i.e., financial and personnel resources, the need to provide additional training or equipment) that could preclude or reduce their ability to become involved in conflict resolution.
Most respondents viewed community-based co-management approaches as realistic (74%) and attractive (63%) options for local governments to exercise in managing human-wildlife conflicts. Most respondents (74%) believed that co-management offered local governments a direct way to be involved in managing their own conflicts. Respondents believed that staffing and budget shortages would be significant impediments that would limit local governmentâ s participation in co-management agreements.
This study clearly illustrates that human-wildlife conflicts are occurring in Virginia, but overall local governments are not at a point when they are willing or able to consider a proactive approach to managing these conflicts. Until some threshold is met or exceeded, leaders in these communities may not be willing to devote the time or resources necessary to enact proactive approaches. Before that threshold is met, the development and utilization of informational and educational resources can increase local governmentâ s capacity to develop and implement a comprehensive wildlife management plan for Virginia communities in the future.Master of Science

Full textAbstract:
The study of conflicts in conservation (also known as human-wildlife conflicts) is a growing field of research in areas where people and wildlife interact, because of the negative impacts each can have on the other. Addressing conflicts is certainly challenging because of the complexities of considering diverse interests from numerous stakeholders and the specific ecological and socio-economic characteristics of a given study system. No matter how complex the system under study is, the aim is in all cases to find effective and sustainable mitigation strategies for local people, as well as for wildlife conservation and local authorities. In this thesis, I look at two of the preliminary steps required to address conservation conflicts and develop efficient long-lasting management solutions: the gathering of ecological data and the assessment of mitigation strategies in the field. To do this, I use two case studies: crop-foraging by African elephants (Loxodonta africana) in northern Botswana, and selective hunting of the red deer (Cervus elaphus) population on the Isle of Rum in Scotland. In Chapter 2, I built a baseline for the level of conflict in the Okavango Delta Panhandle (Botswana) using temporal trends of crop-foraging by elephants as an index of the level of conflict, and subsequently looked at how this relates to trends in agricultural land allocated in the study area, as well as with trends in human and elephant population size. In Chapter 3, I mapped the distribution of the local population of elephants and assessed its interaction with landscape features and sites where crop-foraging events had been recorded. In both chapters (2 & 3) I found that -in general- the number of elephants was not a determinant of the level of conflict in the study area, but that the spatiotemporal distribution of the species as well as the spatial and temporal scales considered were. In the second half of my thesis, I assessed the effects of two common conflict mitigation methods: the use of deterrents (Chapter 4) and lethal control (Chapter 5). I first evaluated the effectiveness of chilli-briquettes in deterring elephants and secondly, I used a modelling approach to predict the demographic effects of increasing levels of selective hunting in a male red deer population. I found that both mitigation methods showed unexpected results, which would not have been detected had I not tested for them. This thesis highlights the advantages of applying methods that are based on informed decisions in areas of conflict, as well as the value of sharing results in conservation management. My findings contribute towards a better understanding of the negative impacts of human-wildlife interactions, which often lead to conservation conflicts, as well as contributing protocols and methodologies that can be adapted and applied elsewhere.

Full textAbstract:
Many predatory species cause negative impacts on human interests by threatening game, livestock or human safety. These impacts can create conflicts where stakeholders differ over wildlife management and when one party is perceived to exert their interests at the expense of the other. Finding effective methods to mitigate conservation conflicts requires an interdisciplinary perspective that investigates (i) the reality of the apparent impacts, (ii) the efficacy of any methods intended to remedy them and (iii) the perceptions, motivations and objectives of key stakeholders. In this thesis, I investigated a conservation conflict in the U.K. surrounding predators and game management. I did so with specific reference to the common buzzard Buteo buteo, a species that, due to predation of released pheasants Phasianus colchicus, is both subject to illegal persecution and on- going controversy concerning the licenced selective removal of ‘problem individuals’. I first review the literature to assess the ecological evidence that certain ‘problem individuals’ can be both disproportionately responsible in impacts upon human interests and more likely to reoffend. I show that while there is evidence for these animals across many different taxa, the benefits of their removal can sometimes be short-lived. I highlight possible indirect impacts of selective management and identify it as a potential compromise between different stakeholder groups. Next, I evaluate the performance of Bayesian stable isotope mixing models (BSIMMs) in quantifying the diets of wild animals. By comparing indirect and direct observations of buzzard foraging, I demonstrate that, with the correct selection of trophic discrimination factors, stable isotope analyses can provide a reliable picture of dietary composition that mirrors direct observations. I then apply these mixing models to evaluate the ecological basis of selective removal of ‘problem buzzards’. The results suggest that the consumption by buzzards of released pheasants is not limited to release pens where gamekeepers perceive buzzard predation to be a problem. However, I then show that stable isotope analysis of blood sampled from two of the four buzzards caught inside pens indicates frequent consumption of released pheasants, relative to the rest of the buzzard population. These results suggest that, while some pheasant consumption may go undetected, selecting only buzzards inside pens for removal is likely to target ‘problem birds’. I then investigate buzzard foraging and breeding ecology on land managed for pheasant shooting. I find that buzzards nest at higher density in areas with greater abundances of pheasants and rabbits Oryctolagus cuniculus. However, records of provisioning from nest cameras showed that only rabbits were caught in proportion to their abundance and only rabbit provisioning rate was associated with buzzard productivity. I suggest that the positive relationship between buzzard and pheasant abundance, although seemingly unconnected to pheasant predation, might influence how gamekeepers perceive buzzard impact. Next, I conduct semi-structured interviews on the subject of predator control with 20 gamekeepers across the south of England, to explore the underlying beliefs, norms and information sources that motivate their behaviour. From these interviews, I identify a number of separate, but interconnected, motivations that influence predator control including professional norms, potential penalties, and interpretations of what is ‘natural’. The influences of these motivations are discussed in detail and a conceptual model, incorporating the theory of planned behaviour, is developed. Finally, the key contributions of this thesis are drawn together and discussed in their wider context. Taken together, the results of this thesis illustrate how predator management occurs simultaneously within social and ecological contexts that incorporate the individual attributes of both predators and people. The results of this thesis have direct implications for the management of predators, the representation of stakeholder perspectives and the design of conflict mitigation measures.

Full textAbstract:
Arbetet är en litteraturstudie och är ett försök att ta reda på två underarter av tigers (Panthera tigris) populationsförändring och anledningen till detta på en tidsskala från 1970 till 2010. De valda underarterna för uppsatsen är sumatratigern och amurtigern. I samband med undersökningen av de två underarternas populationsförändring har fokus lagts på Sumatra och Amurområdet för att kunna få en överblick över de områden där tigrarna återfinns och med den överblicken lättare öppna för att diskutera hållbara bevarandemöjligheter i framtiden. Uppsatsen har i huvudsak diskuterats med stöd av tidigare studier, statistikuppgifter och rapporter i ämnet och därefter har det insamlade materialet analyserats och genomarbetats för att försöka nå fram till nya insikter inom tiger- och landskapsforskningen. Jämförande studier med den svenska vargen används som en utgångspunkt för vad som kan ske om tigern fortsätter att minska eller helt försvinner från sina områden. Trots brister i det statistiska underlaget finns tecken på att fragmenteringen och befolkningstillväxten är viktiga faktorer för sumatratigerns nedgång. Amurtigern visade sig vara mer tålig för både fragmentering och den ökande befolkning i Amurområdet tvärtemot vad tidigare forskning visat, men då båda tigrarnas utbredningsområde har analyserats på liknande sätt trots stora skillnader i förhållande, miljö och storlek så kan detta spela en stor roll i mina resultat jämte tidigare forsknings resultat. Klart är dock att människors allmänna attityd mot rovdjur i deras närområde, så kallade human-wildlife conflicts, komplicerar bevarandefrågan för tigern då skador orsakade av rovdjuren inte ses på med blida ögon och kan vara dyrt att kompensera för.The study is a literature review and seek to find out two subspecies of tiger´s (Panthera tigris) population change and the reasons surrounding this on a time scale from 1970 to 2010. It also includes finding out the landscape and ecological consequences related to this, in order to discuss the sustainable conservation opportunities in the future. The two chosen subspecies for the study is the sumatran tiger and the amurtiger. The method has been mainly supported by previous studies, statistics and reports on the subject, but has allow themselves to be analysed and discussed in search for new fatc that can bring more light over the tigers popoulationchanges and the reserach of the tigerlandscape. Comparative studies with other predators, our Swedish wolf out and foray into the landscape, however, brings us a good picture of what could happen if the tiger continues to decrease or completely disappear from their landscape. Despite declining statistics, there were clear signs that fragmentation and human population growth are important factors to discuss the tiger's decline. The sumatran tiger was shown to be dangerly threatened by deforestation and human population growth in Sumatra, while the amurtiger seemed to be more resistent despite earlier researches has shown. An explanation for this might be the fact that the two subspecies range has been analyzed the same way despite large differences in environment and sieze and this can play a big role in my results that differes from earlier reserach results. It is clear, however, that humans general attitude toward predatos in their local area, so called human-wildlife conflicts, complicates the issue of conservation of the tiger when damage caused by the predators can be fatal and not to easy or affordable to compensate.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCrop raiding by wild animals is becoming increasingly common. In recent years, the management company of the Dona Francisca Hydroelectric Power Plant has received complaints from local residents about a supposed increase in the population of capuchin monkeys, which were allegedly causing "losses" to some farming households. It is crucial to understand people´s perceptions and attitudes towards monkeys to clarify the social factors that intensify conflicts, as well as the factors which favor the coexistence between humans and capuchin monkeys in farmlands. To identify human-wildlife conflicts and their possible causes, this study investigated the perceptions and attitudes of rural community residents in Ibarama (in the Brazilian state of Rio Grande do Sul), in the vicinity of the Dona Francisca dam, with respect to capuchin monkeys. The study was carried out through semi-structured interviews with farm owners and the subsequent categorization of their answers. Thirty-one interviews were conducted between September 2010 and January 2012. Most respondents were over 40 years old and had been living in the area since childhood. Most of them stated that monkeys have always existed in that region, and only two respondents associated the "emergence" of monkeys and the building of the dam. Maize is the main crop consumed. A significant portion of the respondents claimed that monkeys cause damage to their property, but most of them could not estimate the extent of their loss. Nevertheless, most of them consider monkeys to be important to nature and believe that the coexistence of humans and monkeys is possible in those areas. Although these losses financially commit some properties, you can see a scenario favorable to the adoption of conservation and educational practices aimed at protecting the capuchin monkey and its habitat.
As invasões de cultivos agrícolas por animais silvestres vêm se tornando cada vez mais comuns. Em anos recentes a empresa gestora da Usina Hidrelétrica Dona Francisca tem recebido queixas de moradores locais sobre um suposto aumento da população de macacos-prego, os quais estariam provocando prejuízos em algumas propriedades rurais. Compreender as concepções e atitudes do ser humano com relação aos macacos é importante para esclarecer os fatores sociais que intensificam os conflitos, bem como os que favorecem a coexistência entre humanos e macacos-prego nessas áreas. O objetivo desse trabalho foi investigar as percepções e as atitudes de moradores das comunidades rurais em Ibarama, RS, no entorno da barragem Dona Francisca, com relação aos macacos-prego, visando à identificação de conflitos e suas possíveis causas. O estudo foi realizado através de entrevista semi-estruturada com o responsável pela propriedade e categorização das respostas a posteriori. Foram realizadas 31 entrevistas, entre setembro de 2010 e janeiro de 2012. A maioria dos entrevistados possui mais de 40 anos e mora no local desde a infância. A maior parte deles afirma que sempre existiram macacos nessa região e apenas dois associaram o "aparecimento" dos macacos à construção da barragem. O milho é o principal cultivo agrícola consumido. Uma parcela significativa dos entrevistados afirma que os macacos causam prejuízo em sua propriedade, mas a maioria desses não soube precisar as perdas. Apesar disso, a grande maioria considera os macacos importantes para a natureza e acredita ser possível a coexistência entre macacos e humanos nessas áreas. Embora esses prejuízos comprometam financeiramente algumas propriedades, é possível observar um cenário favorável à adoção de práticas educativas e conservacionistas que visem à proteção do macaco-prego e de seu hábitat.

Full textAbstract:
Canis lupus is one of the most important but least studied species of Turkish fauna, however, livestock depredation and recently increased number of publications on attacks on humans intensifies human-wildlife conflict. In this study, wolf depredation is studied in Bozdag in the province of Konya where conflicts between wolves and livestock holders are well known.
The study site holds >50,000 sheep and covers 9 villages and a small town. A total of 13 shepherds are interviewed in 2004 and 2005 to reveal husbandry methods and vulnerability of livestock to wolf attacks in Bozdag. Each flock is attended by a shepherd and several livestock guarding dogs (LGDs), and experiences 1.96 wolf attacks per year, on average, independent of flock size. The flocks attended by less LGDs experience less attacks and therefore, the quality of the LGDs &

not their numbers- are more important. Confining sheep in corrals that are attended by a shepherd and good quality LGDs appears to be the most effective husbandry method to decrease depredation. Human attitude towards wolf is also assessed and the perception of wolf is generally negative
8 out of 11 shepherds are in favour of the eradication of this carnivore. Publicized wolf attacks on humans are compiled from 21 news sources on the internet and records of wolf rabies are sought from various sources. There were five publicized cases of attacks on humans, no verified records of human death between 2000 and 2005. Rabies stands out as the primary reason of wolf attacks, but it requires further research because proper records are missing.

Full textAbstract:
It is widely recognized that human-wildlife conflicts can reduce farmers’ support for long-term species conservation. The subject of human-elephant conflicts is highly relevant in villages around Babati District in North Central Tanzania because of the closeness to Tarangire National Park. The purpose of this study is therefore to examine local farmers’ attitudes toward elephants and the attitudes’ effects on conservation efforts. Primary data was collected through a qualitative approach of semi-structured interviews with twelve farmers in four villages around Babati, with Wildlife Officer Nashon Macokesha at Babati District Council and with Allan Carlson, Nature Conservation Expert at WWF. A thematic analysis was done to make comparisons between the answers from farmers, Macokesha and Carlson. The Theory of Planned Behavior and the Value-Belief-Norm theory were also used to analyze the underlying factors of the farmers’ attitudes. The results of this study show that around half of the farmers have positive attitudes toward elephants, while the other half think negatively of them. Elephants were identified as the most problematic species and crop-raiding as the most problematic type of human-elephant conflict. The problems that farmers experience do to crop-raiding and other types of human-elephant conflicts include the direct effects of lost livelihood and income and indirect effects like health impacts and security issues. The result also indicates that factors affecting farmers’ attitudes toward elephants include: 1) the proportion of available land affected by elephants, 2) the closeness of farmers’ fields to Tarangire National Park, 3) the lack of compensation, 4) the ability to affect the decision-making concerning the human-elephant conflicts and 5) the information about and knowledge of elephants and their importance. The underlying cause of the human-elephant conflicts is identified to be the spatial overlap of the two species. To prevent human-elephant encounters in the first place, thereby reducing the risk of human-elephants conflicts, better land use planning can be used to avoid settlement and cultivation close to protected areas. Buffer zones can be established around national parks and reserves to reduce the overlap between humans and wildlife. Mitigation through preventive and deterrent methods like lighting fires, making noises, using chili-dung or chili-grease to scare elephants off farmers’ fields can also be used. Another alternative is to switch from growing high-risk crops that elephants prefer to crops like chili or sesame which rarely gets eaten by elephants.Att konflikter mellan människor och djurliv kan minska bönders stöd för artbevarande åtgärder är välkänt bland forskare. Konflikter mellan människor och elefanter är vitt förekommande i byar i Babati-distriktet i norra Tanzania på grund av närheten till nationalparken Tarangire. Syftet med denna studie är därför att undersöka bönders attityder till elefanter och attitydernas effekter för bevarandeåtgärder. Primärdata samlades in genom ett kvalitativt upplägg med semistrukturerade intervjuer med tolv bönder i fyra byar i Babati, med Wildlife Officer Nashon Macokesha på Babati District Council samt med Allan Carlson, naturvårdsexpert på WWF. En tematisk analys utfördes för att jämföra svaren mellan bönderna, Macokesha och Carlson och the Theory of Planned Behavior samt the Value-Belief-Norm theory användes för att analysera de underliggande orsakerna bakom böndernas attityder. Resultatet från denna studie visar att ungefär hälften av bönderna har positiva attityder till elefanter, medan den andra hälften har negativa åsikter om dem. Elefanter identifierades som den mest problematiska arten för bönderna och förstörandet av grödor som den mest problematiska typen av konflikt mellan människor och elefanter. Problemen som bönderna upplever till följd av dessa konflikter inkluderar direkta effekter som förlorad inkomst och försämrade försörjningsmöjligheter, men också indirekta effekter som hälso- och säkerhetsproblem. Faktorer som enligt resultaten i denna studie kan påverka böndernas attityder till elefanter innefattar: 1) andelen tillgänglig mark som påverkas av elefanter, 2) närheten från böndernas mark till nationalparken Tarangire, 3) bristen på kompensation, 4) möjligheten att påverka beslutsprocessen gällande konflikten mellan människor och elefanter samt 5) information och kunskap om elefanter och deras betydelse. Den underliggande orsaken till konflikterna mellan människor och elefanter identifieras vara överlappet i användningsområden mellan de båda arterna. För att förhindra möten mellan människor och elefanter, och därmed minska risken för konflikter, behövs bättre markanvändningsplanering så att bosättning och jordbruk undviks i närheten av skyddade områden. Buffertzoner kan också anläggas runt nationalparker och reservat för att minska överlappet mellan människor och djur. Avskräckande åtgärder, som att tända eldar, göra oväsen, tända chilibriketter eller sätta upp chili-rep, för att hålla elefanter borta från böndernas åkrar kan också användas. Ett annat alternativ är att bönderna byter från att odla högriskgrödor som elefanter föredrar till att odla grödor som chili eller sesam, vilka sällan eller aldrig äts av elefanter.

Full textAbstract:
La conservation des populations animales autour desquelles existe une controverse passe entre autres par une compréhension de l’écologie de l’espèce, mais également par une analyse des attitudes humaines vis-à-vis de sa présence. Cependant, ces deux aspects sont rarement mobilisés ensemble au sein de travaux combinant sciences de l’environnement et sociologie. Nous proposons ici une étude portant sur la population d’ours brun (Ursus arctos) résidant dans les Pyrénées, intégrant à la fois dynamique de la population et de sa distribution, et une analyse de l’attitude des Pyrénéens vis-à-vis des plantigrades. Nous conduisons également une réflexion sur les méthodes à employer afin d’intégrer ces résultats au sein d’une approche socio-écologique. Nos modèles écologiques, qui utilisent des données de suivi obtenues dans le cadre d’un partenariat transfrontalier entre France, Andorre et Espagne, mettent en évidence une augmentation des effectifs et une réduction de la distribution de la population entre 2008 et 2014. Si ces conclusions ne semblent pas aller dans le sens d’une dégradation rapide de leur état de conservation, les ours pyrénéens restent menacés du fait de leurs faibles effectifs et du fort taux de consanguinité au sein de la population. Notre enquête sociologique, réalisée dans les communes sur lesquelles l’ours est ou a été présent entre 2008 et 2013, a mis en évidence une hétérogénéité spatiale dans l’attitude des habitants des Pyrénées sur la question de l’ours, avec notamment des variations significatives en fonction de leurs lieux de naissance et de résidence. Nous discutons ensuite d’une approche intégrant résultats de sociologie et d’écologie avec le but de créer un modèle pouvant servir d’outil à un responsable chargé de la gestion ou de la résolution du conflit, en analysant les méthodes à notre disposition, leurs avantages et leurs limites. Nous concluons sur l’intérêt des approches pluridisciplinaire dans la gestion des controverses autour de la conservation de populations animalesThe conservation of controversial animal populations requires an understanding of the species’ ecology, but also an analysis of the human attitudes towards its presence. However, those two aspects are rarely studied together through a combination of environmental sciences and sociology. Here we study the brown bear (Ursus arctos) population residing in the Pyrenees mountains, analyzing both population dynamics and distribution, and the attitudes of Pyrenean people towards the species. We also ponder on the methods to use to combine these results in a socio-ecological approach. Our ecological models, which use monitoring data obtained through a crossborder partnership between France, Andorra and Spain, highlight an increase of population size and a reduction of its distribution between 2008 and 2014. If those conclusions do not seem to indicate a quick degradation of their conservation status, Pyrenean brown bears remain threatened by low numbers and high inbreeding in the population. A sociological study was performed in the municipalities where bear was or had been present between 2008 and 2013. We found spatial heterogeneity in the attitudes of Pyrenean people regarding bears, with significant variations depending on where they were born and where they currently live. We follow by discussing an approach that combines sociological and ecological results, with the goal of building a model that can be used as a tool for someone responsible for managing or solving the conflict; to do this, we analyze the methods available, their strengths and limits. We conclude on the importance of interdisciplinary approaches when managing controversies over wildlife conservation

Full textAbstract:
Le défi de la protection des espèces menacées en Afrique est de concilier de façon durable les objectifs de conservation de la nature, et la nécessité de développement économique des populations humaines. Au Niger, survivent aujourd'hui les dernières girafes d'Afrique de l'Ouest (Giraffa camelopardalis peralta). Ces girafes sont unique à plusieurs titres : (i) elles constituent les seules représentantes de la sous espèce peralta (ii), elles vivent dans une région fortement anthropisée (iii) elles vivent dans une zone non protégée, (iv) et elles ne cohabitent avec aucun prédateur. En 1996, la population était au bord de l'extinction avec seulement 50 individus. Malgré des signes de restauration observés ces dernières années, la sous-espèce est inscrite depuis 2008 dans la liste rouge des espèces menacées de l'UICN (Union Internationale pour la Conservation de la Nature) avec le statut « en danger ». Quels sont les facteurs qui pourraient limiter le taux de croissance maximum récemment observé dans cette population? Est-ce que les conjonctures favorables à l'augmentation de la population sont durables? Aborder les questions de conservation des populations met en avant le besoin de connaitre les paramètres démographiques de la population concernée, et les paramètres environnementaux qui conditionnent sa distribution spatiale. Nous avons réalisé une analyse de l'historique des comptages, puis, nous avons déterminé les paramètres démographiques de la population grâce à une approche par Capture Marquage Recapture. Une analyse spatiale à plusieurs échelles nous a permis de caractériser la distribution des girafes aux niveaux de la population et du troupeau (à partir d'observations directes), et de mesurer la sélection de l'habitat au niveau individuel (à partir d'un suivi par colliers GPS)One of the main challenges for endangered species protection in Africa is to find a sustainable way of integrating objectives of nature conservation with the economic development needs of the local human population. Last West African giraffe population, Giraffa camelopardalis peralta, lives in Niger. These giraffe are unique for several reasons: (i) they represent the only population of peralta sub-species, and (ii) they live in an area densely populated by humans, (iii) which is unprotected and (iv) without predators. In 1996, this giraffe population was almost extinct, with only 50 individuals remaining. Despite signs of population recovery, the sub-species has been classified as “endangered” according to the IUCN Red List assessment criteria. What are the limiting factors for the maximum annual growth rate that has been recorded over the last years in the population? Are favorable conjunctures to this population increasing sustainable? Assessing population conservation requires knowledge of demographic parameters and understanding of the environmental factors driving its spatial distribution. Census data from 1996 to 2009 were analyzed and then demographic parameters through a capture-markrecapture method were determined. A multi-scale spatial analysis allowed me to determine giraffe distribution at both population and herd level (through observations), and to measure habitat selection at the individual level (through GPS satellite collars). Census results, almost exhaustive from 2005 to 2008 highlited an annual growth rate of 12%. This is the maximum growth rate for a giraffe population, and fits with the theoretical maximum growth rate for the species. At the population and herd level, giraffe distribution patterns are driven by food availability. These food resources are seasonally distributed and impacted by human activities. Habitat selection shows that during dry season, giraffe avoid village proximity, where disturbance is high. However, at night giraffe move closer to villages where food resource quantity and quality are higher (tree density, granaries). The use of bean field crop suggests that some cultivated crops gain in attraction and even become favourable to giraffe. This might explain the increase of human-giraffe conflicts. My results clearly show the importance of taking human activities and perception into account, when assessing wildlife conservation strategies

Masai Mara, a large nature reserve in south-western Kenya, was created in the midst of semi-arid agropastoralist rangelands to protect wildlife. Wildlife and indigenous people co-existed for many years, usually with limited conflict; but in recent years, the conflict has intensified, mainly due to increasing human population, changing land use patterns, and altered perceptions of wildlife. This study examines the causes and nature of wildlife-human conflict in the Masai rangelands of Kenya, and considers how wildlife conservation and human development needs can best be integrated.Findings indicate that common conflicts are livestock depredation and crop damage, human deaths or injuries, transmission of diseases, and competition for resources. Land surrounding the reserve can be divided into two distinct topographic and agroclimatic regions. The degree of conflict is spatially varied within the region. Upland ranches have high land use potential, high human and livestock population densities, and more development of agriculture. They experience limited conflict with wildlife. Lowland ranches are more arid, have lower human population density and little agriculture, but have high wildlife and livestock population densities and experience a high degree of conflict. These conflicts vary seasonally, and with distance from the protected area.
Perceptions of wildlife and attitudes towards conservation are related to past experience with wildlife. The degree of loss, effectiveness of damage control, fairness of government compensation, and involvement in wildlife tourism affect the degree of tolerance for wildlife conflict. Various socio-economic factors including level of education, knowledge of conservation priorities, and system of land ownership are related to attitudes towards wildlife. As human activity increases in the region, wildlife is more likely to be displaced. Because most animals are migratory, conflict in the land surrounding the reserve puts the viability of animal population in the protected area in question.
A two-phase program for integrating wildlife conservation with human needs is proposed. The first phase involves designation of the region into four zones: Zone A--the protected area, Zone B--the peripheral area, Zone C--multiple use, and Zone D--agriculture. The second phase of the program is the integration of the wildlife conservation with human interests through: community wildlife-damage-control, compensation for loss, sharing of tourism benefits with local people, conservation education, and local participation in wildlife conservation policy. The program provides a framework within which operational decisions can be made, and serves broader natural resource management and community development objectives in the rangelands.

The aim of the project was to explore the acquisition and dissemination of knowledge amongst decision-makers involved in the management of red deer in Scotland. While research exists on the ecology of red deer habitat, no research exists that focuses on the relationship between the deer and the people responsible for their management. Therefore, this thesis is primarily qualitative research which aimed to explore the various aspects of red deer management in Scotland within the socio-ecological context in which it exists. There are numerous groups with interest in red deer management, however this research, due to scope and time restrictions, was limited to two primary groups, the individuals tasked with implementing policy and the practitioners who carry out culling. During the course of the project, under-researched topics surfaced, highlighting areas of practical and theoretical divergence between stakeholders. This thesis therefore aims to explore how differing views and perspectives of two of the key stakeholder groups – the estate-based practitioners (including stalkers, land-managers, and land-owners) and staff of governmental agencies – influence the management of red deer in Scotland. This research indicates that people with different roles hold different relationships with the deer, which affect management decisions and implementation at local, regional, and/or national level. As with other areas within conservation and wildlife management, this research indicates there is a disconnect between blanket governmental policy and site-specific needs, with a lack of inclusion of practitioner knowledge. Potential future research would include additional qualitative research to follow up some of the management issues raised by this research and formulate recommendations for changes to practice, followed by collection of quantitative data assessing the efficacy of interventions.

Full textAbstract:
Although Panamá is an important global hotspot for biodiversity, basic information on large carnivore and prey distributions as well as habitat needs is largely unknown. Wildlife studies in Panamá have been limited to populations located in protected areas along the Panamanian Atlantic Mesoamerican Biological Corridor (PAMBC) and have not considered potentially important refuge habitats located outside the PAMBC. Further, research on human attitudes and perceptions associated with large carnivores, such as jaguars (Panthera onca), is limited in Panamá. My study was conducted in 2 disparate study areas: Cerro Hoya National Park (CHNP), an isolated remnant of tropical rainforest habitat 125 km from the PAMBC that straddles the Veraguas and Los Santos provinces on the Azuero Peninsula; and Serranía de Pirre (SP), a comparative study area in the PAMBC located in Darién National Park (DNP). I used remote cameras to investigate patterns of site occupancy and detection probabilities, as affected by habitat and anthropogenic influences, for 3 species of felids (jaguars, pumas [Puma concolor], and ocelots [Leopardus pardalis]) and 2 species of peccaries (white-lipped [Tayassu pecari] and collared [Pecari tajacu]). In addition, I assessed attitudes and perceptions of rural Panamanians about jaguars and the conservation of CHNP and DNP via oral surveys. Site occupancy did not appear to differ between study areas for any felid or peccary, but detection frequencies and detection probabilities of focal species were overall higher in SP than CHNP. For collared peccaries, probability of detection was a function of survey year, study area, and Julian date, and estimated occupancy was higher in CHNP than SP. For ocelots, probability of detection was significantly higher in SP than CHNP when an ocelot was detected in a previous occasion. For pumas, detection increased with Julian date in CHNP but was seasonally unaffected in SP. Puma occupancy was higher closer to river systems. For jaguars, detection probability decreased with Julian date, increased with number of camera days per occasion, and was higher in SP than CHNP. Jaguars were more likely to use habitat at higher elevations in both study areas. White-lipped peccaries were never detected in CHNP, which may indicate their local extirpation in this region of Panamá. Regarding surveys measuring perceptions of rural people, factors such as gender, level of education, land ownership, and number of cattle affected knowledge and attitudes towards jaguars and criticism towards park management. Additionally, there was a higher frequency of human-jaguar conflict in SP than CHNP and coyotes (Canis latrans) were the most commonly reported threat to livestock in CHNP. My research elucidates previously unknown distribution limits of jaguars and coyotes in the Azuero Peninsula, as well as providing evidence for the potential local extirpation of white lipped peccaries in CHNP. I provide wildlife managers with improvements for survey design of future occupancy studies in the Neotropics. Further, my research provides targeted areas to prioritize for future wildlife conservation efforts and mitigation efforts concerning human-jaguar conflict.

Full textAbstract:
The recovering harbor seal population along the Swedish west coast has coincided with declining cod stocks. Although the cod stocks were primarily depleted by intense fisheries, some stakeholders argue that reduced seal populations could have direct, positive effects on the cod stocks. The outbreaks of Phocine distemper virus (PDV) in 1988 and 2002 when up to 66% of the harbor seals along the Swedish west coast died, could be viewed as natural experiments allowing for assessment of any positive impacts of reduced mortality from seal predation on cod abundance. I quantified removal from seal predation and fishery landings and analyzed correlations to cod abundance of different length classes. Analyses were conducted for a longer time- series, 1979-2019, reaching back to when removal from fisheries was substantially larger than that from seal consumption. I also analyzed the data with a more recent perspective, 2003-2019, starting after the later PDV outbreak when seal predation relative landing sizes has increased. During this period, fishery discard data is available and included in the models. Methods include graphical presentation, multiple linear regression analyses, and to expand the existing data on seal diet, I collected diet samples of harbor seal feces from two haul-outs in Skagerrak. No statistically significant, negative correlations between seal predation and cod abundance were found in any data set, hence, I cannot support the idea of harbor seals having an impact on cod abundance. Also, the significant correlations between cod abundance and landings were all positive. I argue that culling of seals cannot be motivated as a strategy to help cod recover, as this would jeopardize the persistence of the seal population rather than assuring cod stability.

Full textAbstract:
As suburban and exurban residential developments continue to multiply in urban areas, they encroach on wildlife habitats leading to increased human-wildlife interactions. The animals involved in direct conflict with homeowners are often relocated or exterminated by the homeowners. Often the homeowners contact state licensed wildlife trappers to eliminate the problem animal. In this study I examined how landscape, ecological, and social factors influence the incidence of human-wildlife conflict of thirty two residential areas in the Tampa, Florida metropolitan area. These residential areas, totaling over 300 km2, are part of the urban development gradient representing a range of urban land use from the urban core to exurban residential areas. This study consisted of four phases. In the first three phases, I investigated which landscape, ecological, and social factors contribute to homeowner conflict with wild animals on their property. In the last phase, I combine the significant factors contributing to human-wildlife conflict from the first three phases to build a more complete model.
A spatial analysis of the locations of human-wildlife conflict events recorded by licensed wildlife trappers showed the most significant development and landscape factors affecting human-wildlife conflict reporting in a residential area were human population density and total area of natural habitat immediately adjacent to the residential area. A survey of the relative abundance of conflict prone animals living near and in remnant patches of habitat in suburban residential areas revealed that greater abundance was not correlated with the reported conflict of that species within that residential area. Species that were social, omnivorous, and had some flexibility in home range size were involved most often in conflict in highly urbanized environments. Species that were less social, and were not omnivorous, were not significantly involved in human-wildlife conflict in highly urbanized residential areas. These species tended to be restricted to intermediately urbanized areas like suburban and exurban residential areas.
Several social factors were also significant contributors to human-wildlife conflict as revealed through personal interviews with suburban homeowners in Hillsborough and Pasco counties. Interviews confirmed that most people have positive attitudes toward wildlife, but some form of conflict was reported by thirty four percent of suburban residents, although only seventeen percent of those perceived it as a problem worth spending money to solve. Analysis of the attitudes of residents who reported having experienced problems associated with wildlife on their property, revealed significant negative correlations with statements of environmental concern and concern for the treatment of animals.
Using all the significant variables from the physical landscape, ecological evaluation, and the human attitude study in the suburbs, I developed a statistical model of human-wildlife conflict across the urbanization gradient. While the model has marginal success in terms of practical application for prediction, it is quite valuable for defining the importance of these variables in relation to conflict with certain types of species across the gradient. This set of papers collectively defines relationships between variables existing in urban, suburban, and exurban residential areas and human-wildlife conflict. These factors should be considered when planning new residential areas to minimize human-wildlife conflict while maximizing the residents’ enjoyment of natural areas and species within the residential area.

Full textAbstract:
Conflict with livestock farmers is the most serious threat to the survival of the jaguar (Panthera onca) across its range of 19 countries of the Americas. In this thesis I examine the needs for mitigating human-jaguar conflict at a range-wide scale by: a) reviewing the state of knowledge on the topic, b) modelling the risk of conflict across the range, c) analysing a series of empirical field case studies, and d) proposing appropriate approaches for different levels of conflict. Findings from 43 published studies and 117 expert-described cases show that human-jaguar conflict occurs on large cattle ranches, mixed farms and smallholdings alike. Depletion of prey and poor livestock husbandry are reported as the key reasons for depredation, regardless of ecological, cultural or socio-economic context. Attitudes and tolerance towards jaguars are not necessarily linked to losses, so recent research has focussed on understanding the behaviours of farmers. With 65% of the remaining jaguar range outside of protected areas, effective strategies for coexistence with farmers are essential. By combining geospatial datasets with expert-based information, spatial patterns of human-jaguar conflicts were presented in a predictive model of conflict hotspots. Around 85% of the total jaguar range, 72% of the total Jaguar Conservation Units area and 90% of the Jaguar Corridor area overlap with livestock, and 15% of the jaguar range has risk of conflict. Regions in which jaguars are repeatedly persecuted may become ecological traps and decimate populations. An aggregate study of 17 case studies across seven countries exposed a very large variety of geographic, agronomic and socio-economic contexts. Both within and across case studies there are considerable differences in farmers’ experiences with livestock losses, concerns about depredation, levels of tolerance and attitudes, as well as social norms towards jaguars in each community. No situational factors could be used to predict how farmers perceive jaguars and deal with depredation. The only pattern consistent across case studies was that attitudes towards jaguars are most likely predicted by a factor of perceived loses combined with the social norms of the community. In most scenarios, correctly balanced strategies of improving husbandry combined with behaviour-influencing methods may be the best way forward. To this end, a conceptual model is proposed, which distinguishes three levels of conflict and explains the importance of addressing any underlying history of grievances or incompatibility of values as part of any human-wildlife conflict mitigation strategy.

Full textAbstract:
Human-wildlife conflicts around protected areas are important issues affecting conservation, especially in Africa. In Gabon, this conflict revolves around crop-raiding by protected wildlife, especially elephants. Elephants’ crop-raiding threaten livelihoods and undermines conservation efforts. Gabon is currently using monetary compensation and electric fences to address this human-elephant conflict. This thesis compares the impacts of the human-elephant conflict in Pongara and Ivindo National Parks based on their idiosyncrasy. Information was gathered through systematic review of available literature and publications, observation, and semi-structured face to face interviews with local residents, park employees, and experts from the National Park Agency. This thesis argues that the impacts of human-elephant conflict are more severe in Ivindo compared to Pongara National Park due to their specific characteristics. To effectively address this human-elephant conflict, an adaptive management strategy is needed. This adaptive management strategy should integrate conservation, livelihood security, and combine to the specific characteristics of each park.

Full textAbstract:
Conflict between humans and crop raiding wildlife is a growing problem, particularly in tropical, unmechanised farming communities where increased competition for resources intensifies the likelihood of human-wildlife interactions. However, conflict can arise as much from perceptions of risk as actual damage, and perceived and actual degrees of risk do not always match. Hoima District in Uganda reportedly has a long-standing issue of crop raiding. Forest fragments in northern Hoima District support chimpanzees and other primates, and are surrounded by a mosaic of farms. During this study crop damage was monitored in farms next to four forest fragments each week for one year (November 2006 to November 2007), and farmers’ attitudes to crop raiding were explored through interviews and focus groups. Most farms lost less than 1% of their crops, and more than half of farms did not experience crop damage by large vertebrates (primates, porcupine, bush pig and civet). Cattle were responsible for over one third of the total area of damage; more than all other large vertebrates combined. Whilst local people do not consider crop raiding by wildlife to be as severe a risk to crops as disease and weather, conflict with wild animals does exist. Farmers’ attitudes appear less influenced by the area of crop damaged than by the frequency of damage events (real or perceived) and by factors external to crop loss: i) ability to control loss and impacts of loss, ii) a fear of personal safety, iii) labour requirements of managing crops. That farmers’ opinions of crop raiding animals appear to be shaped more by these external factors than by actual levels of crop loss is a likely consequence of the low level of damage present in the study sites. This research illustrates that perceptions of conflict between humans and crop raiding animals should always be examined in tandem with actual losses, and that conflict may persist in areas where little loss occurs. Employment of amelioration techniques must therefore be selected with care, as inappropriate use of these tools risks focusing farmers’ frustrations onto crop raiding activities and exacerbating conditions.

Full textAbstract:
Free-ranging banded mongooses (Mungos mungo) in northeastern Botswana are infected by a novel Mycobacterium tuberculosis complex pathogen, M. mungi, which putatively infects mongooses through lesions in the skin (often the planum nasale) from an environmental reservoir. To understand the epidemiology of the yearly and highly seasonal outbreaks of M. mungi in this population of banded mongooses, researchers need to understand what factors influence banded mongoose exposure to M. mungi and banded mongoose susceptibility to M. mungi infection. Researchers have no baseline data on the behavioral ecology of this population of banded mongooses - such as home range dynamics, denning ecology, movement ecology, and foraging ecology, all of which may play a role in banded mongoose exposure to M. mungi. Further, researchers have highlighted the potential role of prolonged elevations of glucocorticoids in impairing cell-mediated immunity, which would play a significant role in determining susceptibility to a mycobacterium such as M. mungi, however, researchers have no data on the endocrinology of banded mongooses. Finally, researchers have not detected M. mungi infection in any other population of banded mongooses. Our study population has a gradient of troops (social groups) that vary from troops with extremely close association with humans in a town, to troops associated with humans at tourist lodges within the Chobe National Park, to troops with no discernible association with humans within the national park and surrounding forest reserve. Researchers have few data on how synanthropy (living with humans) affects banded mongoose behavioral ecology and no data on how synanthropy affects banded mongoose endocrinology. Researchers do not know whether or how the high level of synanthropy in this population of banded mongooses plays a role in the epidemiology of M. mungi outbreaks.
Thus, we document here some aspects of banded mongoose home range dynamics, movement metrics, denning ecology and foraging behavior for our study population in northeastern Botswana. We present a novel method for screening data from global positioning system (GPS) collars for large measurement error and we present a detailed home range study. We also document the spatio-temporal dynamics of glucocorticoid production among several banded mongoose study troops across our study site, using a non-invasive assay for fecal glucocorticoid metabolites, which we validated and also present here. We tested to see which factors, including nutritional limitation, predation risk, and reproduction (and associated competition, agonistic encounters, and predation), best explained the variation in glucocorticoid production among our study troops over several years.
We found that the metrics traditionally used to screen data from GPS collars, horizontal dilution of precision (HDOP) or fix dimension (2-D or 3-D), performed poorly relative to a new screening metric that we propose, the estimated elevation error (EEE). We propose that researchers use our screening method, which combines test data and a model-averaging information-theoretic framework that uses a priori candidate models of telemetry measurement error. Although we recommend including EEE in a priori candidate models, it may not describe telemetry error in other systems as well as it did in our own.
Banded mongooses in our study population formed troops of a median of 13 adults (IQR: 11 to 21 adults) and these troops used home ranges of a median of 68 ha (IQR: 39 to 134 ha) with core areas of a median of 15 ha (IQR: 9 to 28 ha). These cores (statistically-clumped space use) occurred at a median volume contour of 66 % (IQR: 58 to 71 %). Synanthropic troops showed more clumped area use than apoanthropic troops (those living away from humans). Synanthropic troops also used man-made structures for den sites in SI{81}{percent} of nights, fed from refuse sites in 13 % of foraging observations, and drank from anthropogenic water sources in 78 % of drinking observations.
From our conducted adrenocorticotropic hormone challenge, we detected valid increases in fecal glucocorticoid metabolite concentrations in mongoose feces using our four tested enzyme-immunoassays. An 11-oxoetiocholanolone assay detecting 11,17-dioxoandrostanes (11,17-DOA) performed best. Using this assay, we detected expected decreases in fecal glucocorticoid metabolite concentrations 48 h after administering dexamethasone sodium phosphate. We also validated this assay using biological events as challenges, in which captive mongooses showed higher fecal glucocorticoid metabolite concentrations during reproductive activity, agonistic encounters, and depredation events. The time delay of fecal glucocorticoid metabolite excretion approximately corresponded with food transit time, at a minimum of approximately 24 h. Fecal glucocorticoid metabolite metabolism was minimal up to 8 h post-defecation.
Reproduction and its associated challenges dramatically increased glucocorticoid production, which otherwise remained low and stable in a captive troop with a constant food supply and lowered predation risk. Variation in glucocorticoid production in free-ranging banded mongooses was best explained by food limitation as described by current nutritional limitation (proportion of fecal organic matter), recent rainfall (which increases soil macrofauna availability), and access to concentrated anthropogenic food resources. Habitat differences in soil macrofauna density and reproductive events also explained variation in glucocorticoid production in free-ranging mongooses, but to a much lower degree. Predation risk, as measured by canopy cover (escape from aerial predators) and group size (decreased per capita vigilance) explained very little of the variation in glucocorticoid production. In the late dry season, banded mongooses in our population may face a ``perfect storm\'\' of nutritional limitation, agonistic encounters at concentrated food resources, aggressive evictions, estrus, competition for mates, parturition, and predation pressure on pups. We suspect that this prefect storm may push glucocorticoid responses into homeostatic overload and may impair cell-mediated immunity in banded mongooses.

Predator-prey dynamics shaped the evolution of morphological and behavioral adaptations that foraging animals use to detect and avoid predators. Wildlife managers can potentially exploit antipredator behavior when attempting to deter animals from areas of human-wildlife conflict. A promising new tool in the field of wildlife damage management is the unmanned aircraft system (UAS; or drone), which might be able to overcome the mobility limitations of other deterrent strategies. The main objective of my study was to determine the behavioral response of blackbirds (Icteridae) to three drones, using a predator model, a standard fixed-wing, and a multirotor as candidate platforms. I evaluated the behavioral response of individual, captive red-winged blackbirds (Agelaius phoeniceus) to the three drones approaching at direct and overhead trajectories, and I evaluated their efficacy on eliciting escape and resource-abandonment behavior in free-ranging blackbird flocks.North Dakota State University.

Full textAbstract:
Elephants are cognitive species that exhibit many types of learning. Associative, social, and insight learning have been investigated with elephants, but one of the simplest forms, habituation, has not. As an individual learns that a stimulus is neither harmful nor beneficial, it will decrease its response to the stimulus through the process of habituation. Elephants possess a well-developed sensory system and may habituate to stimuli that could be used for enrichment and/or management. The aim of this study was to examine the habituation process of elephants in response to repeated presentations of two auditory stimuli –buzzing by a disturbed beehive and the sound of banging on pots and pans, as these sounds invoke alert and avoidance behaviors in wild elephants as part of humanelephant conflict mitigation. I hypothesized that elephants would initially exhibit strong reactions to both sounds, but these responses would diminish over repeated trials. I also hypothesized that their responses to the bee sound would decrease more slowly than to the pot/pans sound because bee buzzing represents a biological cue that a threat is nearby. This study was conducted using four female African elephants (Loxodonta africana) at the Nashville Zoo. Elephants received each stimulus for a 10-day period. On the first sound presentation, the elephants reacted by exhibiting distress, avoidance, and vigilance behaviors. Over repeated presentations, the elephants stopped responding to the stimuli, suggesting habituation had occurred. They also seemed to generalize their habituation between the first and second sound, resulting in a faster habituation to the second sound. Although a preliminary study, the results suggest that elephants learn which stimuli are non-threatening and subsequently stop responding to them, most likely through habituation. Specifically, the elephants habituated to bee buzzing and banging pots and pans, two deterrents used to stop elephants from entering farmlands and eating crops. Habituation is a major concern for the development of effective human-wildlife conflict mitigation and zoo enrichment programs. The results from this study indicate that habituation is an important learning process that should be considered during the implementation of captive and wildlife management, even for highly intelligent species such as elephants.

Full textAbstract:
The support of local communities has become accepted as critical for success in wildlife conservation, particularly in developing areas such as Kenya. Human-wildlife conflict is a major cost to people living amongst wildlife, and a threat to support for conservation. This research focused on conflict experienced by Maasai pastoralists in Laikipia, Kenya, an area of conservation importance and the site of many community conservation initiatives. It was found that the levels of conflict experienced by the communities were much higher than suggested by official reports from the Kenya Wildlife Service. Livestock depredation, mainly by hyenas, was identified as particularly underrepresented. These inaccuracies in the official reports are likely to lead to complications in conservation planning, and should be addressed in order to ensure that the benefits of conservation are going to be sufficient to outweigh the costs of conflict, and satisfy the expectations of local people.L'appui des communautés locales est considéré comme essentiel pour le succès des projets de conservation de faune, en particulier dans des régions en voie de développements tels que le Kenya. Le conflit humain-faune a un coût important pour les personnes vivant parmi la faune, et il est une menace de la conservation. Cette recherche s'est concentrée sur le conflit éprouvé par les pastoralists de Maasai Laikipia, au Kenya, une région d'haute valeur à la conservation et l'emplacement de beaucoup d'initiatives communautaire de conservation. Cette étude conclue que les niveaux du conflit éprouvés par ces communautés étaient beaucoup plus élevés que suggérés par les rapports officiels du Kenya Wildlife Service. La déprédation de bétail, principalement par des hyènes, est identifiée comme particulièrement sous représenté. Ces inexactitudes peuvent mener aux complications dans la planification de projet de conservation. Elles devraient être adressées afin de s'assurer que les avantages de la conservation sont supérieurs aux coûts du conflit, et satisfont les espérances des personnes locales.

Full textAbstract:
Mobile phones are transforming many aspects of rural areas in the developing world. Much of the early research on phones and related information and communication technologies (ICTs) in developing countries has focused on social networking and economic benefits in primarily urban or agricultural settings. Few studies, however, have examined the implications of mobile technologies on pastoralist livelihoods and biodiversity conservation. To build on this opportunity, this study examines the impact of mobile phone technology on four Maasai communities near Tarangire National Park in northern Tanzania. I asked the questions: (1) How do phones affect human-wildlife interactions?; and (2) What are the effects of mobile phone use on measures of human-wildlife conflict (HWC)? This research uses a mixed methods approach to address these two questions and test the hypothesis that mobile phone use reduces HWC. Qualitative group interviews revealed that households use phones to manage wildlife interactions in every aspect of their lives - especially when the interactions relate to pastoralism and crop-based agriculture. Maasai use mobile phones as tools of information distribution to mitigate and reduce the severity of effects of HWC. Multivariate analyses of survey measures of phone use and exposure to conflict (i.e., crop and livestock predation and human attacks) offer mixed evidence that mobile phone use is correlated with a perception of less recent HWC events.

Full textAbstract:
Connection to and appreciate for the natural world are directly linked to positive experiences participating in outdoor nature-based activities. These direct experiences have been declining over the past decade, causing concerns about the perceptions of nature by populations that don’t participate in nature-based activities. This study examines framing of media coverage about human-wildlife conflicts and its implications for perception building by those audiences with less experience in the natural world. Data were collected via daily newspapers across the Intermountain West from 2010 to 2015. Results demonstrated that there were significant differences between newspapers serving larger, more urban communities and smaller, more rural communities. Findings indicate that urban audiences are exposed to messages that discourage participation in the natural world. Messages regarding human-wildlife conflict in newspapers serving larger, more urban communities should be reframed to avoid negative perceptions of nature and to motivate connection to the natural world.

Full textAbstract:
Understanding and addressing conflict between subsistence farmers and wildlife due to crop-raiding is an increasingly crucial conservation issue. Raiding often compromises local food security, reduces tolerance of wildlife, and undermines management efforts. Although many primates consume crops regularly, there are very few quantitative accounts of on-farm primate behaviour or techniques to deter primates from raiding. Working in partnership with farmers, this study was conducted over two primary crop-growing seasons in six villages adjacent to Budongo Forest Reserve, Uganda. Using systematic observational sampling techniques, interviews, and focus groups, the research examined the behaviour of farmers, primates, and other wildlife at farm-forest interfaces to understand the dynamics and parameters of crop-raiding. This information was then used to develop and evaluate a series of effective and locally-appropriate deterrents to raiding. Primates were the predominant diurnal raiders while bush pigs were the mam raiders at night. Six species of primate were observed to raid. Rates of raiding were directly aligned with the availability and maturation of crops, with maize and beans being raided most frequently. Patterns of raiding varied spatially and temporally, and raiding behaviour differed across species. Raiding-group size, duration of raid, and distance travelled onto farm determined crop loss during raiding events. Although crop losses were relatively small they were costly for farmers. Farmers did not detect crop-raiding completely and may underestimate raiding activity. Farmers used a wide range of responses to raids, typically In combination. Deterrents implemented at study farms included alarm systems to improve early detection of wildlife, barriers (nets or fences) and border crops, natural repellents, systematic guarding, and alternative crop locations. Farmers identified benefits and shortcomings for each deterrent, and considered most to be effective and valuable. Insights from. the research may be used to inform intervention strategies to address raiding issues and extend options to mitigate human-wildlife conflict. Recommendations for further research are provided.

Full textAbstract:
Human wildlife conflicts can represent missed opportunities for ecological monitoring, including tracking invasive species. The great cormorant Phalacrocorax carbo sinensis is the centre such a conflict, where the lack of concrete scientific evidence is often replaced by anecdotal evidence, leading to the vilification of these birds. The primary aim of this study was to assess the extent of the overlap between cormorant diet and the fish the fishermen are allowed to catch on the North West coast of Gotland, the Baltic seas´ biggest island. To assess cormorant diet, the otoliths in the cormorant pellets were analysed. Secondary aims included assessing the potential to use cormorant diet as a proxy for local fish abundances by comparing it to monitoring fisheries in the same area. Highly contentious species only included cod, herring and flounder, none of which were commonly consumed by cormorants. Cormorants and the monitoring fisheries found comparable proportions of all species except for flatfish herring sprat, sculpin. We conclude that the cormorant poses a relatively low risk to the fishing industry on the North Western coast of Gotland and that they could potentially be used as a sentinel for local fish abundances, including tracking invasive species such as the round goby.

Full textAbstract:
Conflicts between humans and black bears (Ursus americanus) jeopardize the safety of both humans and bears, especially when bears become food-conditioned to anthropogenic food sources in areas such as campgrounds. Interest in using non-lethal techniques, such as aversive conditioning, to manage such conflicts is growing. I conducted a captive experiment at The Wildlife Science Center in Minnesota and two field experiments in the La Sal Mountains, Utah, to investigate the effects of taste aversion conditioning using thiabendazole (TBZ) with a novel flavor cue and food removal on black bear food consumption and visitation to human food sources. In 2007, I conducted food trials with 6 captive black bears (3 control, 3 treatment). Controls received 1 kg baked goods scented with a peppermint-canola oil mixture and treatments received 1 kg baked goods also scented with a peppermint-canola oil mixture but mixed with 10-20 g TBZ. In the 2007 field experiment, I baited 24 field sites with 300 g of baked goods during a baseline phase for approximately 3 weeks. Half of these sites were then treated with 10 g of TBZ and camphor during a treatment phase for 4 weeks. In 2008, I baited 22 sites with 300 g of baked goods during a baseline phase for approximately 4 weeks. I then removed food and discontinued baiting at half of the sites for 4 weeks. Infrared cameras and barbed-wire hair snags were established at field sites to document bear visitation. I did not establish taste aversion in treated bears in captivity and bears fully consumed food in the majority of trials. Treating food supplies with 10 g TBZ and camphor flavor did not significantly reduce bear visitation (P = 0.615) or food consumption at field sites (P = 0.58). However, I observed a significant reduction in bear activity at sites where food was removed (P = 0.006). Potential reasons for my failure to reduce bear visitation using thiabendazole include insufficient conditioning, reluctance of bears to desist in investigating sites that previously contained untreated food, and masking of a treatment effect due to continued encounters of sites by new individuals.

Full textAbstract:
This qualitative multiple case study explored human-elephant conflict-coexistence relationships and issues of conservation in Namibia (Damaraland) and Sri Lanka (Wasgamuwa) from a posthumanist, multispecies perspective. Within each region, conflict between humans and elephants is considered high, elephants are considered endangered and are of high conservation priority, the human population has grown significantly, and community-based organizations are implementing holistic approaches to increase positive relations between humans and elephants. This study was guided by research questions that explored the current landscape of the human-elephant-conservation nexus within each region, the shared histories between humans and elephants over time, and the value in utilizing more-than-human theoretical and methodological frameworks to enhance human-elephant relationships and support conservation efforts. Data collection methods included participant observation, naturalistic observation, interviews, visual data, and documents. Data was triangulated and analyzed within each case, as well as across cases. Major themes were identified within each case that describe unique contexts, cultures, and shared histories. These findings were then analyzed comparatively. Emergent themes across cases identified ways that a more-than-human framework may be useful in fostering coexistence between humans and elephants and supporting conservation efforts. This study contributes to the evolving scholarship on multispecies approaches to inquiry and methodology from the position of conflict resolution scholar, supports a more inclusive framework for analyzing human-wildlife conflicts, discusses theoretical and methodological implications in multispecies research, and provides recommendations for future research.

Full textAbstract:
This study seeks to find the best strategies to be implemented to decrease the human-wildlife conflict (HWC). Other countries management practises and strategies to manage HWC was reviewed, in order to identify if Skåne county in Sweden could pursue improvements. To be able to tackle HWC, a greater understanding of people's ethical views were investigated and their perceptions of improvements were documented and researched. This study aims to provide quantitative data with web based surveys and spatial mapping of impacts from the HWC in Skåne county. It further aims to map the values that affects society caused by the HWC, and to answer the following questions; What are the optimal strategies in order to decrease HWC in Skåne? Where can cost effective improvements be implemented? This was both answered in the interviews conducted, and the gathered data. Optimal strategies that were detected where Skåne county can improve were; extensive implementations of ecoducts and passages for game, reducing the use of fencing, translocating, compensation actions, increase hunting opportunities and an installment of further game warning systems. Ethical views of different respondents’ towards the HWC were also analyzed. The online survey revealed that there were a difference in respondents views of HWC, based on if they were environmental science students, hunters or the general public. The gathered data and result, stated that the general public and the environmental students/workers were categorized in the ethical views of ecocentrism. The hunters ethical views could not be determined, due to the inconsistency of the answers of the questions. By showing differences and similarities in ethical views and how to manage HWC, strategies and incentives can more easily be adapted, to reach a better community base that can work together to reduce the HWC. Because of the different knowledge of the respondent groups and of their ethical views, there needs to be a broader incentive program that can maintain different interests of people and reduce conflicts, as well as preserve the biological state of ungulates in Skåne. In the online survey, all of the respondents agreed that the stakeholder, most suitable to handle and manage the problematics regarding HWC, is the government/county government. Other stakeholders that were believed suitable for managing HWC in Skåne, were organisations, for-profit companies and lastly, private self-acting individuals. Furthermore, the respondents beliefs on coexistence between humans and wildlife were also studied. The data showed that the general public and the hunters believed that future were to be positive, and the environmental students/workers believe the HWC would still be a problem in the future.

Full textAbstract:
Understanding and addressing conflict between farmers and wildlife due to crop raiding is of increasing conservation concern. Raiding impacts farmers’ livelihoods, reduces tolerance to wildlife and often results in lethal methods of retaliation. Although crop raiding occurs on commercial as well as subsistence farms, there are very few quantitative accounts of on-farm primate behaviour or techniques to deter primates from raiding commercial farms. Working in partnership with commercial crop farmers, this study was conducted in Blouberg Municipality, South Africa. Using systematic behavioural observations, camera trapping techniques, vegetation transects, interviews and a workshop, this research adopts an interdisciplinary approach to examine farmers’ perceptions of nature, behaviour of primates, and crop damage by other wildlife to understand the nature and extent of crop raiding. This information was used to develop and evaluate effective and locally appropriate deterrents to wildlife crop raiding. The farmer-baboon relationship is complicated and filled with ambiguity. Farmers are happy to see baboons in the wild, but on the farm baboons are not welcome. High population numbers and the inability to control baboons are particular concerns for commercial farmers. Baboons were the dominant raiders, whose rates of raiding were influenced most by natural food availability. Vervet monkey raiding was also frequent and was influenced by the presence of baboons on the farm. In addition to primates, 18 other wildlife species were observed within crop fields. Farmers’ perceptions were influenced by duration of raiding, average group size and overlap between farmer activity and crop raiding. Farmers underestimated crop loss to wildlife, but were able to accurately estimate where most damage occurs. The use of bells as an alarm system was not effective at alerting field guards to the presence of vervet raiders. Motion-activated sounds were effective at reducing baboon raiding for a short time, but baboons soon habituated. Electric fencing was effective at keeping most wildlife out of crop fields. The information obtained throughout the thesis was used to provide recommendations to commercial crop farmers to reduce crop raiding by wildlife.

Full textAbstract:
Geographic profiling (GP) was originally developed to solve the problem of information overload when dealing with cases of serial crime. In criminology, the model uses spatial data relating to the locations of connected crimes to prioritise the search for the criminal's anchor point (usually a home or workplace), and is extremely successful in this field. Previous work has shown how the same approach can be adapted to biological data, but to date the model has assumed a spatially homogenous landscape, and has made no attempt to integrate more complex spatial information (eg, altitude, land use). It is this issue that I address here. In addition, I show for the first time how the model can be applied to conservation data and - taking the model back to its origins in criminology - to wildlife crime. In Chapter 2, I use the Dirichlet Process Mixture (DPM) model of geographic profiling to locate sleep trees for tarsiers in dense jungle in Indonesia, using as input the locations at which calls were recorded, demonstrating how the model can be applied to locating the nests, dens or roosts of other elusive animals and potentially improving estimates of population size, with important implications for management of both species and habitats. In Chapter 3, I show how spatial information in the form of citizen science could be used to improve a study of invasive mink in the Hebrides. In Chapter 4, I turn to the issue of 'commuter crime' in a study of poaching in Savé Valley Conservancy (SVC) in Zimbabwe, in which although poaching occurs inside SVC the majority of poachers live outside, showing how the model can be adjusted to reflect a simple binary classification of the landscape (inside or outside SVC). Finally, in Chapter 5, I combine more complex land use information (estimates of farm density) with the GP model to improve predictions of human-wildlife conflict.

Full textAbstract:
Habitat loss and fragmentation and human-wildlife conflicts, often resulting in retaliatory killing in response to livestock predation, are one of the main threats to wild felids worldwide, including pumas (Puma concolor). However, mesocarnivores are more abundant than large carnivores, live closer to human settlements, and drive community structure and processes in similar or different ways from large predators. Understanding both large and small carnivores' habitat use is key to their conservation and management. Thus, there is need to explore the ecological roles of predators (including invasive ones like free-ranging dogs [Canis lupus familiaris] and cats [Felis catus]) to examine how ecological context modulates the ecological roles of carnivores . This is especially important in my study area, which was severely burned by a catastrophic mega-wildfire in 2017.
I used dynamic occupancy modeling of human-wildlife conflict (HWC) across 52 provinces for 8 years in Chile and found that free-ranging dogs outpace pumas in livestock depredation, killing substantially more livestock than pumas. Occupancy models show that HWC occurrence for both dogs and pumas increased with sheep density. Unexpectedly, dog HWC decreased with anthropogenic habitat degradation indicating that dogs may travel far to prey on livestock. The emergence of puma HWC in a site where it did not occur in the previous year was positively associated with anthropic disturbance. Countrywide, dogs HWC occurrence probability was higher than pumas in 43 out of the 49 provinces where both species occurred. I discuss livestock vulnerability, management strategies, and policy to mitigate HWC, and also highlight threats that free-ranging dogs pose to biodiversity conservation and even human public health.
I also used single-species, single-season occupancy models fit to camera-trap data to investigate the patterns of site occupancy and response to mega-wildfires of native mesocarnivores in southern-central Chile: guignas (Leopardus guigna), culpeo foxes (Lycalopex culpaeus) and chilla foxes (Lycalopex griseus). I found that vulnerable guignas avoided burned sites, preferring sites with native, dense vegetation while culpeo foxes were intermediate in being able to use plantations, but avoiding burned sites. Chilla foxes were most tolerant to landscape change with no response to burns and were found closer to human habitation and rivers.
Finally, I used two-species, single season occupancy models, and Kernel Density Estimation on circular data, to investigate the spatial and temporal dynamics, and overlap of native and exotic carnivores. I found that feral cats are a potential threat to pumas, guignas, and native foxes given they overlap extensively in time of activity with these species. Also, feral dogs had the widest distribution of all species indicating that their effects could be ubiquitous on the landscape. Thus, exotic species are damaging to wildlife, to livestock industry, and even to public health. I urge dialog between government authorities, wildlife managers, and scientists to generate a legal and public policy framework to properly managing habitat and HWC in southern-central Chile.Doctor of Philosophy
Landscape transformation and human-wildlife conflict (HWC), which often result in retaliatory killing of wildlife in response to livestock predation, is one of the main global threats to wild cats, including pumas (Puma concolor). Medium-sized carnivores (mesocarnivores or mesopredators) are more abundant than large carnivores, live closer to human settlements and, like large predators, impact ecosystem structure and function significantly. Understanding habitat use of these carnivores is key to their conservation and management and to biodiversity preservation. Thus, there is need to investigate the ecological roles of carnivores (including invasive ones like free-ranging dogs and cats) to determine how interactions with other carnivore species and with the physical environment influence ecological roles of such species. This is especially important in my study area, which was severely burned by a catastrophic mega-wildfire in 2017, and for which there is scant information on wildlife responses to the mega-fire. I determined the distribution and causes of HWC across 52 provinces for 8 years in Chile and found that free-ranging dogs accounted for higher livestock depredation than pumas, killing substantially more livestock. Occurrence of HWC for both dogs and pumas increased with the sheep density of the province. Unexpectedly, dog HWC increased in less degraded habitats, indicating that dogs may travel far to prey on livestock in remote areas. The emergence of puma HWC in a site where it did not occur in the previous year increased with human-caused disturbance. Countrywide, dog HWC was higher than pumas in 43 out of the 49 provinces where both pumas and dogs occurred. I discuss livestock vulnerability, management strategies, and policy changes to address HWC, and discuss the threats that free-ranging dogs pose to biodiversity conservation and even to human public health. I also used remotely-triggered, camera-trap records to explore distribution of three mesocarnivores (guignas, culpeo foxes and chilla foxes across the landscapeand in response to mega-wildfires in southern-central Chile. I found that guignas, a small and vulnerable wild cat, avoided burned sites, preferring sites with native, dense vegetation while culpeo foxes were intermediate in being able to use plantations, but avoiding burned areas. Chilla foxes were most tolerant to landscape change with no response to burns, and they were found closer to human settlements and rivers. Finally, I examined overlap in space and time of day between native species pairs and native and exotic species pairs. I found that dogs were the most widely distributed species across the landscape, but were mostly diurnal while native species were primarily nocturnal. Cats however had high temporal overlap with guinas and chilla foxes, highlighting the potential for competition between them.. Thus, exotic species are damaging to wildlife, livetock and even huan health. I discuss the management implications and urge dialog between government authorities, wildlife managers, and scientists to generate a legal and public policy framework to properly managing habitat and HWC in southern-central Chile.

McDonald, Lucian R. "Urban Alaskan Moose: An Analysis of Factors Associated with Moose-Vehicle Collisions." DigitalCommons@USU, 2019. https://digitalcommons.usu.edu/etd/7547.
Full textAbstract:
As human populations continue to grow and encroach into wildlife habitats, instances of human-wildlife conflict are on the rise. Increasing numbers of reported wildlife-vehicle collisions (WVCs) provide tangible evidence of anthropogenic impacts on wildlife as well as increasing threats to human health and safety. Increasing WVCs are of particular concern, especially those involving large-bodied ungulates such as moose (Alces spp.), because of the increased risk of property damage, personal injuries, and human fatalities. Motorists directly involved in a WVC are at risk of injury or mortality, but other motorists are also put at risk due to road obstructions and traffic congestion associated with WVCs. Mitigating these impacts on motorists and wildlife requires investigation into the temporal and spatial factors leading to WVCs.
In Alaska, most WVCs involve moose (Alces alces), a large bodied ungulate capable of threatening human life when involved in a collision. Each moose-vehicle collision (MVC) in Alaska is estimated to cost $33,000 in damages. With this analysis, I analyzed the plethora of factors contributing to moose and motorist occurrence on the road system and motorist detection based on a historical dataset of MVC reports throughout Alaska from 2000 to 2012 and a dataset of field-derived measurements at MVC locations within the Matanuska-Susitna Borough from 2016 to 2018. My first analysis focused on the daily and annual trends in MVC rates as compared to expected moose and human behavioral patterns with a focus on guiding mitigation strategies. Fifty percent of the MVCs reported between 2000 and 2012 occurred where the commuter rush hours overlapped with dusk and dawn in winter, and the artificial lighting differences between boroughs suggest a link between artificial lighting and reduced MVCs.
To focus more specifically on roadside features contributing to MVC risk, I collected and analyzed local and regional scale land cover and road geometry data at reported MVC sites in an area with a rapidly growing human population. I compared these data to similar data collected at random locations near documented MVC sites and at locations where moose that were fitted with global-positioning system (GPS) transmitters crossed highways. I used generalized additive mixed models to delineate which of the variables impacted the risk of both moose road crossings and MVCs. Moose road crossings were influenced by approximations of spatial, seasonal, and daily moose density as well as the proportion of deciduous-coniferous and coniferous forest in the area and the number of possible corridor or land cover types surrounding the site. The best MVC risk model was described by expected seasonal and daily changes in moose density and local scale measurements, including the sinuosity of the road, the height of vegetation near the road, and the angle between the road surface and the roadside. Together this information should guide transportation and urban planners in the Matanuska-Susitna Borough to use roadside vegetation removal, seasonal speed reduction, improved lighting strategies, dynamic signage, or partnerships with mobile mapping services to reactively reduce MVCs and to focus future road planning in areas with lower moose abundance and build roads that increase visibility and detection distances in areas where moose are common.

Full textAbstract:
Many believe community-based ecotourism (CBE) can assist in conservation efforts and community development; however, little research has been done to assess the potential of CBE in a specific region. As part of a large, long-term, international research project, I define three problematic areas that may impede successful CBE efforts in the Kasigau location of southeast Kenya: bushmeat utilization, community attitudes and wildlife abundance. Samples of meat purchased from butcheries and meat markets are identified to species using molecular analysis, community attitudes are ascertained via written social surveys and transect sampling methods are used to determine the relative abundance and diversity of wildlife on Maungu Ranch in Kasigau. Through these three separate analyses a clear picture of problematic issues facing CBE in Kasigau becomes clear. This study provides valuable baseline data that can be used in future research to determine the impacts of CBE in the region.

Full textAbstract:
Includes bibliographical referencesHuman-wildlife conflicts are increasing globally and are believed to be one of the most prevalent and intractable issues that face conservation biologists today. One such conflict is found on golf courses, where high numbers of geese can come into conflict with residents and members. In South Africa, the indigenous Egyptian Goose Alopochen aegyptiaca population has increased dramatically over recent years and as a result they are often seen as nuisance animals whose population requires active management. Most non-lethal methods of goose control have had little success due to habituation to their presence, whilst the use of lethal methods are often deemed socially unacceptable. In this study we experimentally investigated the efficacy of falconry as a management tool to mitigate human-wildlife conflict. We hypothesised that the use of falconry would re-establish a landscape of fear, whereby habitat choice is influenced by the perceived fear of predation, resulting in the local departure of geese to a safer habitat, thereby reducing the population of geese to a tolerable level. Absolute counts of geese and analysis of vigilance levels were conducted at three golf courses in the Western Cape which included two control sites and a treatment site. The results of the experiment indicate that goose abundance declined by 73% at the treatment site after falconry was initiated, and that this was well over the losses due to direct predation. Vigilance levels increased by 7 6% during the treatment period, with no such changes observed at either control site. Additionally, vigilance was higher when filmed from a golf buggy compared to when filmed on foot, which may suggest the geese also learned to associate the golf buggy with the threat of predation, enhancing the overall efficacy of the falconry. While there is a relatively small lethal aspect to falconry, the results of this study confirm that a reduction in the population of geese can be achieved by simulating the naturally occurring non-lethal effects of predation that have been lost in some habitats, as a result of anthropogenic changes to the landscape. To our knowledge, this is the first truly experimental test of the efficacy of falconry to reduce nuisance birds and these important ecological findings have relevance for techniques that people deploy for dealing with human wildlife conflict, particularly where lethal options are unfavourable.

Full textAbstract:
[Partial abstract]: Human-wildlife conflict is a widely observed phenomenon and encompasses a range of negative interactions between humans and wildlife. Depredation upon livestock and game species proves to be the prevalent form of this conflict and often results in the killing of carnivores. Within the South African context, despite intense lethal control, two sympatric mesopredators, the blackbacked jackal (Canis mesomelas) and the caracal (Caracal caracal), remain common enough to be considered a major threat to human livelihoods through depredation. Wildlife ranches and livestock farms dominate the landscape in the Eastern Cape Province. Moreover, human-predator conflict within the region is extensive as both the black-backed jackal and caracal are seen to be inimical by landowners. Understanding this conflict is essential for mitigating any potential adverse environmental reactions (i.e. range collapses or extinctions) and requires knowledge of anthropogenic, ecological and environmental factors. I interviewed 73 land owners across five municipal boundaries in the Eastern Cape to quantify perceptions of predator control methods.

Human wildlife conflict is a considerable conservation challenge that threatens many carnivore species worldwide and is a result of complex socio-economic and ecological processes. An understanding of the drivers of conflict is essential for any efforts to achieve coexistence. This study investigated the levels of conflict, livestock management and tolerance amongst the farming communities of the Southern and Western Kalahari in Botswana. A questionnaire survey was completed with 310 farmers throughout the region. The majority of respondents regarded coexisting with carnivores as a challenge, with losses due to depredation perceived as the greatest problem facing farmers. Conflict was widespread throughout the study area, with some spatial variations for certain species. Cattle management levels were low and while smallstock management was better, the use of improved levels of management could reduce current levels of conflict. Tolerance levels were generally low with few respondents seeing the benefits of coexistence with carnivore species. The results indicated that farm type, gender, education level, source of income, livestock numbers, location and land use all have an effect on perceived conflict and tolerance levels and strongly interact with each other. In general cattleposts were characterised by higher proportions of females, lower education levels, more benefits derived from wildlife and veld products and fewer livestock than fenced ranches. They also experienced more conflict, carried out more management and had better tolerance levels. It could be that closer connections to the land and deriving benefits from natural resources resulted in more tolerance and this is certainly worth further investigation. An improvement in the use of effective methods of livestock management, targeted environmental education programs to develop a greater awareness for the conservation value of carnivores and a diversification of livelihoods to include benefits from natural resources have the potential to reduce conflict and improve tolerance in the Kalahari region.

Full textAbstract:
The black bear (Ursus americanus) has returned to Kentucky and is now part of a reproducing population in the southeastern Cumberland Mountain region. The broad objective of this project was to examine the interactions between people and bears, with the ultimate goal of improving bear management in a way that addresses stakeholder concerns. Using interviews of regional stakeholders, participant observation, and media reports collected between summer 2003 and fall 2006, I investigated how the presence of black bears in Harlan and Letcher counties in Kentucky has had an impact on area residents. I complemented this information with observations of bear behavior and an analysis of bear capture and handling data collected within the study period. Artificial provisioning of bears was widespread and >60% of black bears captured were confirmed to use anthropogenic foods at least some of the time. I found a significant difference (P<0.0001) in the apparent physical condition of confirmed anthropogenic feeding bears and bears whose feeding behavior was unknown, and similar differences in physical condition between bears captured along traplines in Harlan and Letcher counties when compared to bears captured along traplines in Bell County (P<0.01). Mean litter size was 3.25 ± 0.11 (SE), significantly above average for eastern North America (P<0.05) although cub survival remains unknown. All documented mortality of adult bears was human-caused. Anthropogenic food sources may affect bear behavior, survival, reproduction, and physiology, as well as bring bears into close contact with humans. Artificial provisioning is currently an important part of bear-human interaction in eastern Kentucky, both facilitating bear tourism as well as precipitating nuisance problems. Cessation of provisioning could have important consequences for the developing tourism industry in the region and for the bears themselves. Both the Kentucky Department of Fish and Wildlife Resources and many local people have an interest in conserving bears, but problems have arisen due to differing conceptions of appropriate or desirable management. A better understanding of the human dynamics and cooperation taking place in this situation could provide much-needed information both in Kentucky and in other localities where stakeholders are debating how to co-exist with wildlife.

Full textAbstract:
This study conducted an evaluation of farmer and shepherd perceptions on Anatolian Shepherd dogs, used as livestock guarding dogs to mitigate farmer–wildlife conflict and meet conservation ends. The case study involved Anatolian Shepherd dogs bred at the Anatolian Shepherd Dog Breeding Project in the Namaqua National Park, and placed mostly on farms and at stock posts near the Namaqua National Park in the Northern Cape. The data were collected during structured and semi-structured interviews with livestock farmers and shepherds that received Anatolian Shepherd dogs from the Breeding Project. Anatolian Shepherd dogs were evaluated in terms of their contribution to reduce livestock losses and conservation of wildlife species. In terms of effectiveness in preventing or reducing livestock losses, 84% of the dogs eliminated or reduced livestock losses. Respondent satisfaction with the dogs was high, with 95% of respondents willing to recommend the Breeding Project and the use of Anatolian Shepherd dogs. Of the respondents, 95% perceived their dogs to be economically beneficial. Another 48% of respondents reported some form of behavioural problems at least once during the placement of the dogs. The most common reported problem was resting in the shade rather than accompanying the livestock. However, corrective training was effective in all cases where training was undertaken immediately. In terms of conservation, fewer respondents used lethal predator control methods in the years after placement of the dogs than before their placement. The overall perception regarding the use of lethal control methods (e.g. gin traps, shooting and poison) was that such control is cruel and that it is better to use non-lethal control methods only. However, a few respondents reported that lethal control measures were occasionally necessary to make a living when no other control measures were available, especially when the herd was relatively large. The effects of Anatolian Shepherd dogs on non-predator species in this study were minimal. The presence of the dogs therefore aided predator conservation and improved farmer tolerance of predators, especially by effectively reducing livestock losses.
