Abstract:
Understanding the occurrence patterns of forest pests is fundamental for effective forest management from both economic and ecological perspectives. Here, we review the history of the occurrence patterns and causes of outbreaks and declines of pests in Korean pine forests over the last 50 years. During this period, the major pests of pine forests in Korea have shifted from pine caterpillar (Dendrolimus spectabilis Butler) to the pine needle gall midge (PNGM, Thecodiplosis japonensis (Uchida and Inouye)) and finally to pine wilt disease (PWD) caused by the pine wood nematode (Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle). Outbreaks of pine caterpillar, a native species in Korea, have been recorded as far back as 900 years, and it was the most relevant forest pest in Korea until the 1970s. The decline of its importance has been attributed to reforestation and higher levels of subsequent natural enemy activity. The PNGM is an invasive species, first discovered in Korea in 1929, that became widely distributed by 1992 and the major forest pest in the 1980s and 1990s. A suite of parasitic wasps attacking the PNGM contributed at least partially to the decline of PNGM densities. Following the decline of the PNGM, damage from PWD has increased since 2003. These shifts in major forest pests might be related to changes in forest composition and interactions among forest pests. Therefore, a new management strategy for controlling forest pests is required to mitigate the decline of pine forests in Korea.

Abstract:
The health of the forestlands of the world is impacted by a number of insect pests and some of them cause significant damage with serious economic and environmental implications. Whether it is damage of the North American cypress aphid in South America and Africa, or the destruction of maple trees in North America by the Asian long horned beetle, invasive forest pests are a major problem in many parts of the world. Several studies explored microbial control opportunities of invasive forest pests with entomopathogenic bacteria, fungi, and viruses, and some are successfully utilized as a part of integrated forest pest management programs around the world. This manuscript discusses some invasive pests and the status of their microbial control around the world with entomopathogenic fungi.

Abstract:
Invasive forest pests can cause environmental and economic damage amounting to billions of dollars (US) in lost revenues, restoration and response costs, and the loss of ecosystem services nationwide. Unfortunately, these forest pests do not stay confined to wildland forest areas and can spread into suburban and urban areas, imposing significant costs on local governments, homeowners, and management agencies. In this study, a contingent valuation experiment is used to estimate Florida residents’ willingness to pay (WTP) a monthly utility fee that would protect urban forests from invasive pests by implementing a monitoring and prevention program for their early detection and eradication. On average, the respondents are WTP US $5.44 per month to implement the surveillance program, revealing an aggregate WTP in the order of US $540 million per year. The results also reveal that respondents are sensitive to the scope of the program, with higher rates of participation and higher WTP for a program that is more effective at preventing forest pest invasions.

Abstract:
A risk analysis framework comprised of assessment, response and communication elements is discussed in the context of forest pest management in Canada. Despite many shared pests and common issues in resource management, capacity in forest pest management varies greatly by jurisdictions depending on historical, socio-economic and cultural expectations. Research and operational expertise is separated among jurisdictions as is responsibility for native and alien pests. A risk analysis framework provides a structure for the development of common evidence-based analysis, harmonized responses and best practices. Two case studies: mountain pine beetle, a native insect, and gypsy moth, an alien invasive insect, are presented to illustrate the process.

Abstract:
Worldwide, a large number of potential pest species are introduced to locations outside their native ranges; under the best possible prevention scheme, some are likely to establish one or more localized populations. A comprehensive early detection and rapid-response protocol calls for surveillance to determine if a pest has invaded additional locations outside its original area of introduction. In this manuscript, we adapt and spatially extend a two-stage sampling technique to determine the required sample size to substantiate freedom from an invasive pest with a known level of certainty. The technique, derived from methods for sampling livestock herds for disease presence, accounts for the fact that pest activity may be low at a coarse spatial scale (i.e., among forested landscapes) but high at a fine scale (i.e., within a given forested landscape). We illustrate the utility of the approach by generating a national-scale survey based on a risk map for a hypothetical forest pest species threatening the United States. These techniques provide a repeatable, cost-effective, practical framework for developing broad-scale surveys to substantiate freedom from non-native invasive forest pests with known statistical power.

Abstract:
The forest landscape of the United States has changed over time, as has public concern for the trees, water, and wildlife. Early in the history of the United States, forests were viewed as an encumbrance and an inexhaustible resource, used to meet the needs of a growing nation. Around 1900, it became clear that old approaches were not sustainable and forest pathology saw its beginning. Annual lumber production increased from 5.4 billion to 44.5 billion board feet. Forest pathologists were called upon to help manage forests for a variety of products, with a focus on decays of wood and wood products. Projection of timber famine stirred public concern, and a number of laws were enacted to deal with the issue. Pathologists were called upon to deal with many of the issues associated with intensive management, and new pests such as chestnut blight and white pine blister rust demanded attention. Then pathologists were called upon to help manage for multiple benefits, and the issues became more complex. Pests such as mistletoes, root diseases, rusts, nursery pests, and urban pests presented new challenges. Concepts such as landscape level assessments, ecosystem management, and multiple-use led to the management of forests to provide for a complex variety of needs. Management objectives vary across the landscape, and pathologists find themselves working with managers who want to maximize fiber production, those that manage areas set aside for special purposes, and all combinations in between. Issues such as acceptable levels of pests, nonnative invasive species, landowner values, visual and watershed quality, and best management practices must be considered in an ever-changing landscape.

Abstract:
The forests of North America provide a variety of benefits including water, recreation, wildlife habitat, timber, and other forest products. However, they continue to face many biotic and abiotic stressors including fires, native and invasive pests, fragmentation, and air pollution. Forest health specialists have been monitoring the health of forests for many years. This paper highlights some of the most damaging forest stressors affecting North American forests in recent years and provides some projections of future risks.

Abstract:
Understanding the biosecurity risks that invasive alien insect pest species currently ravaging forest trees pose is of great importance to forest ecosystems and health. This problem has posed significant challenges to researchers, relevant stakeholders, policy makers and national biosecurity agencies worldwide. This study gives an overview of the top 15 suspected insect pest species most likely to invade or have already invaded forested habitats in order to disrupt ecosystem services and biodiversity within the borders of Nigeria through borderline states (Gombe, Jigawa, Borno, Yobe, Sokoto, Cross River and Lagos). For Nigeria as a whole, all of these top 15 pest species have already established, with identified intra- border line states having no significant effect on severity of invasions ( F1,6=0.07, P=0.910) when compared to identified inter-border line states. This study concludes that the immediate biosecurity risks from already identified invasive insect pests are greater from outside country (inter) borders of Nigeria than within state-to-state (intra) borders of Nigeria. Our findings have potentially significant implications for immediate implementation of national biosecurity forest policy Acts in compliance with Cartagena and Nagoya protocols, emphasizing the need to initiate and implement biosecurity measures simultaneously with any ongoing trans-national border interventions.

Abstract:
China is implementing an extensive urban forestry plan in Xiongan New Area (XNA), a new city in Hebei province. The city has been designated to serve Beijing’s noncapital functions and promote the integration of the broader Beijing–Tianjin–Hebei city-region. As part of a green initiative to minimize environmental impacts and its carbon footprint, a massive urban forestry system has been planned on an unprecedented scale, expected to cover over 600 km2 by 2030. Using science to inform policy, one major goal is to simultaneously minimize impacts of invasive species, while making urban forests more resilient to potential invasive species threats. In this review, we introduce these urban forestry plans such as basic concepts and principles for afforestation, tree species to be planted, delineation of existing pests already established, and expected forest invasive species of concern threatening the new area. Finally, we introduce a framework for invasive pest management strategies in XNA based on a “big data” approach and decision system to minimize impacts of invasive species. This new approach to urban forestry has the potential to become an exemplary global model for urban forestry planning, one that integrates research activities focused on forest health surveys and monitoring with sustainable forestry management. Finally, we provide an overview of the forest health policy required for the design of an unprecedentedly large new urban forest from initial planning to full implementation of an integrated forest management program.

Abstract:
As tree species composition in forests of the northeastern United States changes due to invasive forest pests, climate change, or other stressors, the extent to which forests will retain or release N from atmospheric deposition remains uncertain. We used a species-specific, dynamic forest ecosystem model (Spe-CN) to investigate how nitrate (NO3–) leaching may vary among stands dominated by different species, receiving varied atmospheric N inputs, or undergoing species change due to an invasive forest pest (emerald ash borer; EAB). In model simulations, NO3– leaching varied widely among stands dominated by 12 northeastern North American tree species. Nitrate leaching increased with N deposition or forest age, generally with greater magnitude for deciduous (except red oak) than coniferous species. Species with lowest baseline leaching rates (e.g., red spruce, eastern hemlock, red oak) showed threshold responses to N deposition. EAB effects on leaching depended on the species replacing white ash: after 100 years, predicted leaching increased 73% if sugar maple replaced ash but decreased 55% if red oak replaced ash. This analysis suggests that the effects of tree species change on NO3– leaching over time may be large and variable and should be incorporated into predictions of effects of N deposition on leaching from forested landscapes.

Abstract:
Au cours des dernières décennies, la détérioration de la santé des forêts a entraîné des épidémies fréquentes des ravageurs et pathogènes. Ces phénomènes menacent la capacité des forêts à fournir des biens et services écosystémiques à la société. Il est donc nécessaire de maintenir la santé des arbres et de réduire les effets des parasites et des agents pathogènes. Cette thèse considère trois problèmes de gestion du point de vue économique : l'invasion actuelle, l'invasion attendue d'un agent pathogène, et les attaques d'un parasite endémique. À partir de ces trois problèmes de gestion, la thèse vise à évaluer les impacts des ravageurs et des pathogènes forestiers et à informer sur la manière dont les ressources peuvent être réparties de façon optimale pour assurer la fourniture de biens et de services par la forêt à long terme.Les invasions biotiques ont un impact sur les prix des produits du bois du fait des chocs d'approvisionnement qui, à leur tour, influencent les choix de gestion forestière. Ceci permet d'introduire des effets de réaction entre les dynamiques écologiques et de marché. Le premier article vise à évaluer ces impacts en combinant un modèle d’équilibre partiel avec des modèles de diffusion spatiale et de mortalité, calibrés pour représenter le dépérissement du Frêne en France (causé par le pathogène Hymenoscyphus fraxineus). Les résultats montrent que les impacts dépendent généralement de la distribution des ressources, de la propagation du pathogène et de la structure du marché. On observe que les choix d’adaptation des gestionnaires forestiers (c'est-à-dire les choix de régénération et de récolte) sont une composante non négligeable de la perte de volume totale.Le deuxième article est axé sur la surveillance et le contrôle d’une invasion attendue. La surveillance et la détection précoce des espèces envahissantes sont importantes pour atténuer les dommages et réduire les coûts de contrôle. Dans le cas où plusieurs propriétaires sont concernés, l’effort de surveillance des propriétaires plus proches du point d'introduction n’est pas optimal, car il ne prend pas en compte les effets négatifs de l'invasion dans les propriétés voisines. Grâce à un jeu différentiel, combiné à un modèle épidémiologique, nous avons calculé la solution non coopérative et coopérative. Nous avons conçu un paiement monétaire pour soutenir la coopération en fonction d'une décomposition intertemporelle du système de négociation de Nash. Les résultats nous montrent que ce paiement garantit que l’accord entre les deux propriétaires est crédible et incitatif. Le modèle est calibré pour l’éventuelle invasion du nématode du pin (Bursaphelenchus xylophilus) dans le Massif Landais.L'objectif principal du troisième article est d'adapter la gestion forestière aux perturbations biotiques et abiotiques. On combine le modèle classique de Faustmann avec un modèle dynamique de population de ravageurs et un modèle de tempête pour calculer l'âge de coupe optimale et le bénéfice actualisé en séquence infinie (BASI) pour différents scénarios de perturbations. Le modèle est appliqué aux dégâts de la chenille processionnaire du pin (Thaumetopoea pityocampa) dans les Landes. Nos résultats ont montré que les tempêtes ont tendance à réduire l'âge optimal de la récolte, alors que le parasite tend à l'augmenter. Les éclaircies augmentent la rentabilité et constituent une stratégie de couverture efficace contre les deux risques. Dans le troisième article, nous avons introduit une règle de décision cut-or-keep pour modéliser le problème du propriétaire forestier après une tempête. Ces implications en termes de gestion sont étudiées plus en détail dans le quatrième article. Notre règle de décision conduit à des gains plus élevés (dans environ 75% des cas) qu’en suivant la règle, généralement utilisée en économie, qui consiste à couper et à replanter les arbres survivants indépendamment du niveau de dégâts
In recent decades, the deterioration of forest health resulted in frequent pests’ outbreaks and the diffuse pathogens’ presence. These phenomena threaten forests’ ability to supply ecosystem goods and services to the society. It is therefore necessary to maintain tree health and reduce pest’s and pathogen’s impacts. This thesis approaches three management problems from an economic perspective such as the current invasion and the incumbent invasion of a forest pathogen as well as the outbreaks of a native pest. Starting from these three pest and pathogen management problems, the thesis aims at assessing the impacts of forest pests and pathogens and, secondly, informing how resources can be optimally allocated for assuring the long-term provision of good and services.Pest and pathogens invasions have an impact on the prices of wood products via supply shocks, which, in turn, influence forest management choices, thus introducing feedback effects between market and ecological dynamics at a large scale. The first paper aims at evaluating these impacts by combining a recursive partial equilibrium model with spatial-explicit pathogen-spread and pathogen-induced mortality models calibrated to represent the ash dieback in France (caused by the pathogen Hymenoscyphus fraxineus). Results showed that impacts are not homogeneous across regions and generally depend on the resource distribution, pathogen spread and market structure. We observed that the behavioural adaptation of forest managers (i.e., regeneration and harvesting choices) is a non-negligible component of the total standing volume loss.The second paper focusses on monitoring and control of an incumbent invasion. Monitoring and early detection of invasive species is important to mitigate the damages and reduce the control costs. However, when multiple decision-makers are involved, the monitoring effort of frontier landowners (landowners closer to the introduction point) is suboptimal because it does not consider the negative impacts of the invasion spreading to neighbouring properties. Through a two-player differential game combined with an epidemiological compartmental model, we computed the non-cooperative and the cooperative solution. We designed a monetary payment to sustain cooperation based on an intertemporal decomposition of the Nash bargaining scheme. We showed that this payment assured time-consistent outcomes, meaning that the ex-ante agreement between the two landowners was credible and self-enforcing. The model was calibrated for the possible invasion of the pine wilt nematode (Bursaphelenchus xylophilus) in south-western France.In the last two papers, the analysis is downscaled from the landscape level to the stand level and concentrates on a native defoliator pest. The main objective of the third paper is to adapt forest management to biotic and abiotic disturbances. The classic Faustmann model was combined with a pest population model and a windstorm model to compute the optimal rotation age and the land expectation value (LEV) for different disturbances scenarios. The model was calibrated for maritime pine (Pinus pinaster) plantations in south-western France and Pine Processionary Moth (PPM, Thaumetopoea pityocampa) cyclical outbreaks. Our results showed that storms tend to reduce the optimal harvest age, whereas PPM tends to increase it. Overall, the impact of PPM on the rotation length prevails and, here, risks increase rather than decrease the optimal rotation length. Thinnings increased profitability and constitute an effective hedging strategy against both risks. In the third paper, we introduced a cut-or-keep decision rule to model the forest owner problem after a storm event. Its economic and management implications are further investigated in the fourth paper. Unlike previous economic studies which assumed clearing and replanting regardless of the level of damages, the cut-or-keep condition led to higher payoffs in roughly 75% of the cases

Abstract:
Invasive species exact important ecologic, economic, and cultural tolls in forests. This research focused on the intersections of invasive ecology, forest management, and a forest commodity. Invasive ecology was explored through an assessment of two potential biological control agents of hemlock woolly adelgid. The two species of silver fly (Leucopis spp.) from the Pacific Northwest were first examined for temporal resource partitioning patterns. The niches of these species were then examined spatially by developing a species distribution model. Leucopis spp. exhibited sinusoidal patterns of daily emergence when examined over a 29-day period, with peak daily abundances that were inversely related. Spatially, however, landscape-scale and climatic indicators were not significant in predicting the presence of Leucopis spp. in the Pacific Northwest. This adds important information about niche dynamics of Leucopis spp. in the Pacific Northwest, which may have logistical and operational implications for their use in the USDA Forest Service’s Hemlock Woolly Adelgid Initiative. Additionally, the potential opportunities and risks of using wood that has been impacted by invasive species and pests was explored through a literature analysis focused on three species posing a threat to northeastern US forests: emerald ash borer, hemlock woolly adelgid, and southern pine beetle. Based on this review, I concluded that although opportunities for the use of this wood are sometimes recognized, the phytosanitary risks in feedstock pre-treatment are not being directly addressed in US-related literature. These studies provide important evidence for adaptive solutions to forest pests that consider both forest health and forest economics.

Studies show that the number of biological invasions has increased. The spread of species from their native range to other places is directly related to the increase in transport and movement of people and their goods. The Pine Wood Nematode (Bursaphelenchus xylophilus) (PWN), the causal agent of the pine wilt disease, is an example of this problem, originated from North America, has become a serious pest on Eurasia. This dissertation aims to understand if environmental factors are determining tree mortality in an area where the PWN has been confirmed since 2009. The study area is located in the centreal part of Portugal, a complex area regarding the topography and soil making it also complex concerning climatic and ecological conditions, providing a good study case on the possible interaction between a biological invasion and local environmental conditions. In order to evaluate the study area several of environmental parameters were determined, and analyzed in GIS. Additionally it was determined the proportion of recently dead trees in randomly selected pine forests within the study area. The Binary logistic model showed that temperature in the warm trimester was the only parameter that better predicted the mortality. Climate change models predict an increase in the temperature in the future, thus indicating that the susceptability of Pinus pinaster to the PWN will increase.

Abstract:
The Eurasian spruce bark beetle Dendroctonus micans is a major pest of spruce which is expanding its range in France, Turkey, England and Wales. Its monospecific predator Rhizophagus grandis has followed naturally the bark beetle into most areas and, since the 1960s, has also been mass-produced and successfully released within newly infested locations.

In this scope, the development of an effective trapping method would be very useful to assess the bark-beetle presence at previously uninfested sites, or predator establishment after release or natural spread. We demonstrated the efficiency of oxygenated monoterpenes-baited kairomone traps to monitor R. grandis in various epidemiological conditions, including areas localized behind or at the limit of the pest’s distribution, or in areas where artificial releases were performed. Because the predator is strictly species-specific, another exciting possibility offered by the kairomone trapping is the indirect monitoring of the pest itself in areas of unknown status (e.g. areas under colonization, or considered as at risk at medium- term).

R. grandis is also considered as one of the most valuable natural enemies to strike aggressive North-American Dendroctonus species. In this respect, R. grandis has been recently applied in a neo-classical biological program against the red turpentine beetle D. valens, which invaded China from North America in the late 1990’s. In laboratory tests conducted on pine logs in the laboratory, or on living pine trees in the field, we demonstrated that R. grandis adults can successfully enter and reproduce into D. valens galleries.

In Europe, R. grandis is the only species regularly found in the brood systems of D. micans, where adults and larvae attack the gregarious larvae of their prey. In such enclosed systems, R. grandis’ functional response is therefore influenced by various interrelated components, such as the prey density, the predator density, or the prey distribution. Measuring the predator’s success in terms of larval survival and growth rates, we demonstrated the time spent by R. grandis larvae to wound and kill their prey to be the main factor limiting their development. This factor may be considerably influenced by the proportions of diseased, wounded or molting prey rise in the brood system, for instance as a result of an increase in prey density, or due to the presence of conspecific adults (which wound their prey but do not consume them entirely). Furthermore, our tests suggest that no cannibalism or noticeable intraspecific competition occurred between R. grandis larvae, whereas some lighter mode of competition probably took place.

R. grandis also exhibits a reproductive numerical response to prey density, which mainly relies on the perception of chemical stimuli and inhibitors released in the bark beetle brood system. In the current study, we developed a non-destructive approach to follow the dynamics of volatile compound production, using sequential sample collection on SPME fibers. Our tests demonstrated that the larval activity of D. micans or D. valens strongly influences the release of some oxygenated monoterpenes. However, our attempts to correlate the relative quantities of some identified chemicals to offspring production were less successful as it concerns the identification of potential oviposition stimuli and inhibitors.

The problematic rose by the progression of D. micans, as well as detailed results of each of the described above studies are discussed in the two published papers and the three manuscripts forming this thesis. Bringing all these studies together, several perspectives are also presented in the general discussion.

Ravageur des épicéas, Dendroctonus micans est toujours en voie d’extension en France, en Turquie, en Angleterre et au Pays de Galles. Dans la plupart de ces zones, le dendroctone est accompagné de manière naturelle par son prédateur monospécifique, Rhizophagus grandis. Depuis les années 1960, le prédateur a également fait l’objet d’une production de masse et de programmes de lâchers dans les zones d’arrivée récente du scolyte.

Dans le cadre de la lutte biologique contre D. micans, les gestionnaires forestiers doivent donc estimer au plus tôt la présence du ravageur dans des zones jusque là indemnes, mais également vérifier l’établissement du prédateur par progression naturelle ou résultant d’introductions délibérées. Dans la présente étude, nous avons démontré l’efficacité de pièges d’interception appatés à l’aide de monoterpènes oxygénés pour la capture de R. grandis. Celle-ci s’est faite dans différentes conditions épidémiologiques, incluant notamment des zones situées en arrière du front de progression du scolyte et des zones où des lâchers artificiels ont été réalisés. Comme R. grandis est strictement inféodé au dendroctone, un autre avantage de la technique est la possibilité de réaliser un dépistage indirect du ravageur dans les zones où son statut est incertain (zones en cours de colonisation, ou considérées comme à risque à moyen terme).

Par ailleurs, R. grandis est également considéré comme un des meilleurs ennemis naturels potentiels pour lutter contre d’autres espèces de Dendroctonus aggressifs. Dans cette optique, R. grandis a été récemment utilisé dans un programme de lute biologique contre D. valens, ravageur invasif arrivé en Chine dans la fin des années 1990 en provenance d’Amérique du Nord. Nous avons démontré la capacité de R. grandis à s’introduire et à se reproduire dans les galeries de D. valens lors de tests de laboratoire, mais aussi sur des arbres vivants en pinèdes.

En Europe, R. grandis est strictement inféodé aux galeries de D. micans, où larves et adultes du prédateur s’attaquent aux larves grégaires du scolyte. Dans ce système clos, la réponse fonctionelle de R. grandis est influencée par plusieurs facteurs étroitement corrélés, la densité de proies, la densité de prédateurs, et la distribution des proies. En mesurant l’efficacité de prédation de R. grandis en termes de survie des larves et de taux de croissance, nous avons démontré l’influence sur leur développement du temps passé par les larves à blesser et à tuer leurs proies. Ce facteur est par ailleurs fortement dépendant de la proportion de larves malades, blessées ou en cours de mue au sein du système ;une proportion qui peut augmenter en réponse à une augmentation de la densité de proies, ou lorsque des adultes sont présents (ceux-ci blessent les proies mais ne les consomment pas entièrement). Enfin, nos tests suggèrent qu’il n’existe que peu de cannibalisme ou de compétition intraspécifique entre larves de R. grandis, tandis que des modes de compétition moins importants prennent vraisemblablement place.

R. grandis présente également une réponse numérique reproductive à la densité de proies disponibles, principalement basée sur la perception de stimuli et d’inhibiteurs présents dans les galeries du scolyte. Par la collecte de composés volatils présents dans ces systèmes à l’aide de fibres SPME, nous avons développé une méthode non-destructive pour suivre la dynamique de production des médiateurs chimiques. Nos tests ont démontré que l’activité des larves de D. micans ou D. valens influence fortement la dynamique de production de certains monoterpènes oxygénés. En revanche, il n’a pas été été possible de corréler les différents composés identifiés au nombre de larves de R. grandis présentes dans le système.

La problématique soulevée par la progression de D. micans, de même que les résultats détaillés de chacune des études décrites ci-dessus sont discutés dans les deux papiers publiés et les trois manuscrits formant cette thèse. Les différentes perspectives apportées par ce travail sont également présentées dans la discussion générale.

Abstract:
Doutoramento em Engenharia Florestal e dos Recursos Naturais - Instituto Superior de Agronomia / UL
Leptoglossus occidentalis Heidemann (Heteroptera: Coreidae) is an invasive pest seriously damaging conifer seeds. Native from North America, the insect was first detected in Europe in 1999, and recorded in Portugal in 2010. Both nymphs and adults feed on seeds of several conifer species. Bug impact on seed production of Stone pine, Pinus pinea, is of major concern in the Mediterranean Basin countries because cone production and seed yield have decreased during the last years quite simultaneously to the records of L. occidentalis. Thus, the insect has been considered the most plausible cause of this decrease. However, there was still a substantial lack of knowledge about the effective impact of bugs and their ecological adaptations on Stone pine. My main goal was to add valuable and pertinent knowledge to understand the interactions between seed bugs and Stone pine. At first, a careful revision of all the literature available about Leptoglossus occidentalis was carried out, together with discussions with other European researchers working on this pest, in order to define the PhD aims. The PhD plan was then divided into three main issues. I first characterized and measured the importance of bug damage on seeds of Stone pine. In a second part, I investigated the ecological interactions between invasive bugs and Stone pine cones and seeds. Bug host preference was tested between Stone pine and the other two main native pine species growing in southern Europe (P. pinaster and P. halepensis), and cues possibly underlying such preferences were suggested. I also evaluated the impact of the bug in Stone pine seed orchards under two different management strategies. In a third part, I suggested possible invasion routes of L. occidentalis in the Iberian Peninsula, using genetic data and field records

Abstract:
The Spanish slug (Arion vulgaris) is one of the most problematic invasive species in Europe and a serious pest species in agriculture and gardens, and it can have negative effects on native slug species. In this study, we used passively intergraded transponder (PIT) telemetry to determine the movement behavior of 57 Spanish slugs during autumn in two different habitats: a private garden and a deciduous forest, located in Karlstad municipality, Sweden. The slugs generally moved within relatively small areas. There was a difference between the movements between the two habitats, with slugs moving longer distances per day (2.0 m day‑1) and over larger areas in the forest than in the garden (1.1 m day-1). Local control measures are therefore potentially effective in gardens and in agricultural landscapes, since the Spanish slug there concentrate within patches of habitat. To develop control methods to mitigate the impact of this problematic slug, we need more basic ecological knowledge, and this study provides such knowledge.
Den spanska skogssnigeln (Arion vulgaris) är en av Europas mest problematiska invasiva arter och ett allvarligt skadedjur för jordbruk och trädgårdar. Den kan också ha negativa effekter på inhemska snigelarter. I den här studien använde vi telemetri baserat på passivt integrerade transpondrar (PIT) för att bestämma rörelsemönstret hos 57 spanska skogssniglar under hösten i två olika habitat: en villaträdgård och en lövskog, i Karlstads kommun, Sverige. Sniglarna rörde sig inom små områden. Det var en skillnad mellan rörelserna i de två habitaten, sniglarna förflyttade sig längre distanser per dag (2,0 m dag-1) och över större områden i skogen än i trädgården (1,1 m day-1). Lokala kontrollåtgärder är därför potentiellt effektiva i trädgårdar och jordbrukslandskap, då den spanska skogssnigeln där koncentrerar sig inom fläckar av habitat. För att utveckla kontrollmetoder för att minska påverkan av den här problematiska snigeln, så behöver vi mer grundläggande ekologisk kunskap, och den här studien förser oss med sådan kunskap.

Abstract:

Due to overpopulation and resource-poor habitat structure, deer threaten the future of oak and other browse-sensitive species in hardwood forests. Appropriate tools must be used to ensure desirable, diverse, and ecologically stable regeneration of future forests and the sustainability of native plant communities. We performed two experiments and a review to examine the effectiveness of available methods for managing browse of hardwood seedlings and to discover how these interact with each other and other silvicultural methods. First, we examined how fencing interacts with controlled-release fertilization, seed source (genetically select and non-select), and site type (afforested and reforested sites) to enhance the regeneration of planted northern red oak (Quercus rubra L.), white oak (Quercus alba), black cherry (Prunus serotina), and black walnut (Juglans nigra) at five sites in Indiana. Fencing proved to be the greatest determinant of seedling growth, survival, and quality. Fertilizer enhanced the early growth of white oak and black cherry, though for black cherry this occurred only inside fences. Select seed sources grew better and showed greater quality; however, the survival of select seedlings was limited by deer browse in absence of fences. Trees at afforested sites had lower survival if left non-fenced. Secondly, we also investigated how fencing and invasive shrub removal affected natural regeneration, species richness, and ground-layer plant cover under closed-canopy forests. Honeysuckle (Lonicera maackii) removal had a variable effect depending on species and site. Positive effects were most common for shade-intolerant species, while negative effects occurred for a few shade-tolerant species at some sites. Deer fencing had a positive effect on cherry and hackberry seedling density, and a negative effect on elm seedling density. Honeysuckle and deer fencing interacted antagonistically in some instances. Fencing without honeysuckle removal resulted in lower elm abundance and herbaceous-layer cover. In the densest invasions, leaving honeysuckle intact resulted in a complete lack of recruitment into the sapling layer. Our experiment suggests that invasive shrub removal and fencing be done together. Finally, we synthesized the existing literature on browse management options for hardwood regeneration to evaluate their relative effectiveness. Fences, tree shelters, repellents, facilitation by neighboring plants, deer population control, timber harvest, and slash all had positive effects on height growth of regenerating seedlings under deer browse pressure. Fences were more effective at reducing browse than repellents, while fertilizers increased browse and had no effects on growth.

Abstract:
AbstractManaging invasive species becomes increasingly difficult and expensive as populations of new pathogens, plants, insects, and other animals (i.e., pests) spread and reach high densities. Research over the past decade confirms the value of early intervention strategies intended to (1) prevent invasive species from arriving within an endangered area or (2) detect and respond quickly to new species incursions (Baker et al. 2009; Ewel et al. 1999; Holden et al. 2016; Leung et al. 2014). The goal of such biosecurity approaches is to keep or return the density of invasive species to zero so that damages from those pests might be prevented or to confine populations to localized areas so that damage from those species might be limited (Magarey et al. 2009). Prediction, prevention, early detection, eradication, and other rapid responses, all components of proactive management, are less costly and more effective than reactive tactics (Epanchin-Niell and Liebhold 2015; Leung et al. 2002; Lodge et al. 2006; Rout et al. 2014) (Fig. 6.1). Prediction is achieved through risk assessment (a process to forecast the likelihood and consequence of an invasion) and pathway analysis (a process to evaluate the means by which invasive species might be brought into an area of concern). Prevention is achieved through a variety of measures including regulations and quarantine treatments. Indeed, pathway analyses and subsequent regulation of those pathways are considered “the frontline in the prevention of biological invasions” (Hulme 2009) and cost-effective approaches (Essl et al. 2015; Keller et al. 2007; Leung et al. 2002; Tidbury et al. 2016). Surveillance is fundamental to early detection, and if a target species is detected, the primary rapid responses are eradication, containment, or suppression (reviewed in Beric and MacIsaac 2015). Early intervention strategies often operate at spatial scales that are much greater than the scale at which most land managers operate. Success thus requires effective coordination among researchers, regulators, and managers at international, national, sub-national, and local levels.

Abstract:
AbstractThe root cause of the biological invasion problem is globalization, which has facilitated the planet-wide breakdown of biogeographic barriers to species migration (Mooney and Hobbs 2000). In order to understand and manage the problem, coordination on a global scale is essential, and international cooperation among affected countries as well as with countries of pest origin must therefore play a critical role in virtually all aspects of research on biological invasions (Chornesky et al. 2005; McNeely et al. 2001; Perrings et al. 2010; Wingfield et al. 2015). Here we discuss key aspects of research on biological invasions, where international collaboration and coordination are important, and what infrastructures play a role in this work.

This chapter provides a holistic understanding of the existing conditions of urban green spaces in Sabah by reviewing relevant past studies and publications. Nature serves as the foundation in the establishment of pocket parks, urban parks, and forest protected areas that are made available for public access within and outside of the major urban areas in Sabah. Presently, both native and exotic flora and fauna species are coexisting at the local urban green spaces, although some invasive exotic species have developed into urban pests of Sabah. Moreover, the importance and functions of urban green spaces in maintaining the well-being of mankind and ensuring the survival of indigenous wildlife species are acknowledged by society. Nevertheless, much research is required to fill up the research gaps of urban forestry, and also to provide solutions to the existing problems that happened at the urban green spaces in Sabah.

Abstract:
The trees, developed green spaces, and natural areas within the City of Austin’s 400,882 acres will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the City Austin to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how less common native species, nonnative species, and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening trees and forests in Austin. Major current threats to the region’s urban forest include invasive species, pests and disease, and development. Austin has been warming at a rate of about 0.4°F per decade since measurements began in 1938 and temperature is expected to increase by 5 to 10°F by the end of this century compared to the most recent 30-year average. Both increases in heavy rain events and severe droughts are projected for the future, and the overall balance of precipitation and temperature may shift Austin’s climate to be more similar to the arid Southwest. Species distribution modeling of native trees suggests that suitable habitat may decrease for 14 primarily northern species, and increase for four more southern species. An analysis of tree species vulnerability that combines model projections, shifts in hardiness and heat zones, and adaptive capacity showed that only 3% of the trees estimated to be present in Austin based on the most recent Urban FIA estimate were considered to have low vulnerability in developed areas. Using a panel of local experts, we also assessed the vulnerability of developed and natural areas. All areas were rated as having moderate to moderate-high vulnerability, but the underlying factors driving that vulnerability differed by natural community and between East and West Austin. These projected changes in climate and their associated impacts and vulnerabilities will have important implications for urban forest management, including the planting and maintenance of street and park trees, management of natural areas, and long-term planning.
