Abstract:

Detection dogs for wolf scat can assist in conservation-monitoring of wolves. In this pilot project, the first encounters of experienced detection dogs with wolf scat were documented. It was tested how a dog, trained with only a few scat samples (minimally four, maximally six), could generalise towards new unknown wolf scats and discriminate them from distracting odours. Four dogs all showed a behavioural expression of aversion upon first presentation with wolf scat during their initial training to fixate on wolf scat. The dog that showed the least aversion to wolf scats was trained during two

Abstract:

ABSTRACT Conservation detection dogs have been widely used for finding scats, retreat sites and specific plant and animal species for a variety of purposes, including monitoring, management, biosecurity and eradication programs. Their cost-effectiveness appears well established in finding cryptic and rare animals, yet they are not included in the Department of Biodiversity, Conservation and Attractions’ published search protocol for bilbies. In this study a human searcher located six of 90 scats (6.7%) compared to the conservation detection dog that located 89 of 90 bilby scats (98.9%). The do

Abstract:

Detection dogs are increasingly used to locate cryptic wildlife species, but their use for amphibians is still rather underexplored. In the present paper we focus on the great crested newt (Triturus cristatus), a European species which is experiencing high conservation concerns across its range, and assess the ability of a trained detection dog to locate individuals during their terrestrial phase. More specifically, we used a series of experiments to document whether a range of distances between target newts and the detection dog (odour channelled through pipes 68 mm in diameter) affects the l

Abstract:

Interspecific interactions can be a key driver of habitat use, and must be accounted for in conservation planning. However, spatial partitioning between African carnivores, and how this varies with scale, remains poorly understood. Furthermore, most studies have taken place within small or highly protected areas, rather than in the heterogeneous, mixed-use landscapes characteristic of much of modern Africa. Here, we provide one of the first empirical investigations into population-level competitive interactions among an African large carnivore guild. We collected detection/non-detection data f

Abstract:

In conservation, consistent and extensive under-funding has necessitated creative thinking to address conservation issues on a low budget, and innovations are burgeoning as a result. One example is the use of dogs that, thanks to their heightened olfactory abilities and bond with humans, are trained to detect odours of interest to conservationists. Conservation dogs have proven to repeatedly outperform alternative survey methods in terms of accuracy, efficiency and/or cost. They have now been used for the detection of endangered and invasive species, fauna and flora, direct and indirect (e.g.

Conservation detection dogs (CDDs) are trained to locate biological material from plants and animals of interest to conservation efforts and are often more effective and economical than other detection methods.

Training skilled volunteers to work with suitable pet dogs may help address this constraint.

Abstract:

AbstractIn recent years, the potential to locate endangered animals using scent trained detection dogs (conservation detection dogs) has gained attention. Among vertebrates, conservation detection dogs have demonstrated a remarkable capacity to detect the scent of endangered mammals, reptiles, and birds, but their use in detecting amphibians is only beginning to be explored. A lack of work in this area is surprising given that amphibians are declining faster than any other vertebrate taxa. Moreover, amphibians are generally small, highly cryptic and breed in complex habitats, making them diffi

Abstract:

Conservation detection dog handler teams (CDDHTs) offer many potential benefits to the world of conservation. Seabird populations are an important component of marine ecosystems. However, they are threatened by several anthropogenic activities, including the introduction of invasive species. Although CDDHT can support seabird conservation through invasive species management efforts and population assessments, they are under-utilised. A lack of methodological standardisation within CDDHT work and the under-publishing of their use within seabird research leads to difficulties in conducting new C

Abstract The endangered natterjack toad (Epidalea calamita) faces ongoing habitat loss, requiring effective conservation measures. Field surveys must therefore address its highly variable detectability in terrestrial habitats. We investigated the factors influencing capture success comparing two methods: artificial cover boards (ACBs) and wildlife detection dogs (WDDs). We first analysed environmental and training factors influencing toad detectability for four detection dogs with varying experience using a binomial generalized linear model (GLM). Then, we compared capture success of ACBs and

Abstract:

Abstract Monitoring large carnivores is imperative for conservation planning, but is difficult due to their elusive behaviour and natural rarity. Some carnivores such as the cheetah (Acinonyx jubatus) are particularly wide ranging and often go undetected despite being present, or are detected at rates too low to make meaningful quantitative inferences. The combination of minimally invasive survey techniques, such as detection dog surveys and camera traps, holds promise for improving monitoring efforts of large carnivores. We surveyed a cheetah population within the Acacia savanna biome of cent

ABSTRACT Freshwater turtles are one of the most threatened vertebrate groups and face multiple threats including habitat loss, predation, and road mortality. Wildlife Detection Dogs (WDDs) have been used to aid in conservation globally. However, their use for freshwater turtle conservation has received minimal research attention. This descriptive study explores the efficacy of using a WDD to locate both turtles and nests, to protect them from mortal threats. A WDD was trained to detect turtle-related odours, specifically female turtles, eggs, and nests. Deployment at two wetland sites in Weste

Abstract:

AbstractConservation detection dogs (CDD) use their exceptional olfactory abilities to assist a wide range of conservation projects through the detection of target specimens or species. CDD are generally quicker, can cover wider areas and find more samples than humans and other analytical tools. However, their efficacy varies between studies; methodological and procedural standardisation in the field is lacking. Considering the cost of deploying a CDD team and the limited financial resources within conservation, it is vital that their performance is quantified and reliable. This review aims to

AbstractThe development and use of cost-effective and appropriate survey methods to assess species distribution and to monitor range expansion and contraction of wild populations is crucial due to the limited financial resources for conservation. Of particular importance, yet little studied, is the ability to collect information before a wild population is well established, i.e. at the early stages of recolonisation. During 2018 and 2019, we used camera traps, audio recorders, and scat detection dogs simultaneously to investigate composition, detection probability, and territorial extent of a

Guyana contains a wealth of intact tropical forest (∼18.4 million ha) and savanna (1.6 million ha) habitats, but management of this species is hindered by a lack of data. We present two photographic records (consisting of nine individuals) of bush dogs from camera-traps set in the Kanuku Mountains Protected Area (KMPA) – the first of this species in Guyana.
