Vultures are declining worldwide with poisoning being the greatest threat in Africa. Using a novel capture-recapture model applied to carcasses found by 51 GPS tracked vultures, we estimated the exposure, threat, and risk of poisoning to vultures in southern Tanzania. Exposure to poisoning was defined as the areas that vultures use and where carcasses are likely to be found by a given individual. We used a human footprint map as a proxy for threat, identifying locations where poisoning was possible. Risk of poisoning was determined as areas with an overlap of exposure and threat. We found that locations with the greatest risk of poisoning were within 20 km of protected areas. Although most high-risk areas we identified fell within this buffer, our risk assessment method identified additional hot-spots including some high-risk areas that fell outside nearby buffers. We found that our risk assessment allowed us to identify more localised, high-risk areas that cover a much smaller total area. This gives more precise insight into where conservation management should be prioritised and limited resources should be focused.}, journal={BIOLOGICAL CONSERVATION}, author={Peters, Natasha and Kendall, Corinne J. and Davies, Jacob G. and Bracebridge, Claire and Nicholas, Aaron and Mgumba, Msafiri P. and Beale, Colin M.}, year={2023}, month={Jan} } @article{kendall_bracebridge_lynch_mgumba_monadjem_nicholas_kane_2023, title={Value of combining transect counts and telemetry data to determine short-term population trends in a globally threatened species}, ISSN={["1523-1739"]}, DOI={10.1111/cobi.14146}, abstractNote={Abstract}, journal={CONSERVATION BIOLOGY}, author={Kendall, Corinne J. and Bracebridge, Claire and Lynch, Emily C. and Mgumba, Msafiri and Monadjem, Ara and Nicholas, Aaron and Kane, Adam}, year={2023}, month={Sep} } @article{kendall_carrier_folta_tinka_fraulo_leeds_lukas_2022, title={Can teacher-centered community-based conservation programs influence student household sustainable behaviors near a biodiversity hotspot?}, volume={2}, ISSN={["2578-4854"]}, url={https://doi.org/10.1111/csp2.12648}, DOI={10.1111/csp2.12648}, abstractNote={Abstract}, number={4}, journal={CONSERVATION SCIENCE AND PRACTICE}, publisher={Wiley}, author={Kendall, Corinne J. and Carrier, Sarah J. and Folta, Elizabeth and Tinka, John and Fraulo, Aimee and Leeds, Austin and Lukas, Kristen E.}, year={2022}, month={Feb} } @article{peters_beale_bracebridge_mgumba_kendall_2022, title={Combining models for animal tracking: Defining behavioural states to understand space use for conservation}, volume={9}, ISSN={["1365-2699"]}, DOI={10.1111/jbi.14483}, abstractNote={Abstract}, journal={JOURNAL OF BIOGEOGRAPHY}, author={Peters, Natasha M. and Beale, Colin M. and Bracebridge, Claire and Mgumba, Msafiri P. and Kendall, Corinne J.}, year={2022}, month={Sep} } @article{ogada_virani_kendall_thomsett_odino_kapila_patel_wairasho_dunn_shaw_et al._2022, title={Evidence of widespread declines in Kenya's raptor populations over a 40-year period}, volume={266}, ISSN={["1873-2917"]}, DOI={10.1016/j.biocon.2021.109361}, abstractNote={Kenya's wildlife has been declining substantially for decades, due to rapid human population growth and its associated impacts on natural habitats. Predators and scavengers are particularly sensitive to anthropogenic pressures, and their changing status has corresponding impacts on the ecosystem services they provide. To estimate rates of change in Kenya's raptor populations we compared linear encounter rates (individuals 100 km−1) recorded during road surveys conducted in 1970–1977 and 2003–2020. Encounter rates for 19 out of 22 species examined had fallen, by a median of 70% among those showing a significant or near-significant change. No species had increased significantly. Declines had occurred among all vulture and large eagle species, and were especially pronounced among once-common small and medium-sized raptors. Our findings demonstrate the importance of protected areas (PAs) for Kenya's remaining raptor populations. The median encounter rate for vultures and large eagles had dropped by 23% within PAs and by 76% in unprotected areas. Smaller species showed divergent trends in relation to PA status, their median encounter rate increasing by 104% within PAs while declining by 85% elsewhere. Based on projected declines over three generation lengths, 45% of the species examined would qualify as nationally Endangered or Critically Endangered. Key threats include electrocution/collision with energy infrastructure, deliberate and incidental poisoning, and impacts associated with habitat degradation. Kenya's raptor declines could be reversed through enhanced management of PAs, mitigation of specific threats and the implementation of species recovery plans; all requiring steadfast government commitment and close collaboration with conservation stakeholders.}, journal={BIOLOGICAL CONSERVATION}, author={Ogada, Darcy and Virani, Munir Z.

Studies on ranging behavior provide insight into the utility of protected areas. Vultures are one of the fastest declining groups of birds globally and are popular subjects for telemetry studies, but continent-wide studies are lacking. To address how vultures use space and identify the areas and location of possible vulture safe zones, we assess home range size and their overlap with protected areas by species, age, breeding status, season, and region using a large continent-wide telemetry datasets that includes 163 individuals of three species of threatened Gyps vulture. Immature vultures of all three species had larger home ranges and used a greater area outside of protected areas than breeding and non-breeding adults. Cape vultures had the smallest home range sizes and the lowest level of overlap with protected areas. Rüppell's vultures had larger home range sizes in the wet season, when poisoning may increase due to human-carnivore conflict. Overall, our study suggests challenges for the creation of Vulture Safe Zones to protect African vultures. At a minimum, areas of 24,000 km 2 would be needed to protect the entire range of an adult African White-backed vulture and areas of more than 75,000 km 2 for wider-ranging Rüppell's vultures. Vulture Safe Zones in Africa would generally need to be larger than existing protected areas, which would require widespread conservation activities outside of protected areas to be successful.}, journal={BIOLOGICAL CONSERVATION}, author={Kane, Adam and Monadjem, Ara and Aschenborn, H.

In the African savannah, habitat loss and particularly tree damage caused by elephants have been suggested as possible factors in the decline of large bird species. Given the recent declines of vultures and other scavenging raptors, it is critical to understand if nest availability is a limiting factor for these threatened populations. Loss of woodland, partially due to elephant populations, has been reported for the Mara‐Serengeti ecosystem. Data on characteristics of trees used for nesting were collected for white‐backed, lappet‐faced, white‐headed vulture, and tawny eagle nests in Masai Mara National Reserve, Kenya. Nest tree characteristics were compared with the distribution of a random subsample of trees to assess nest preferences and determine suitability of available trees. Nearest neighbor distances were estimated as well as availability of preferred nesting trees to determine if tree availability is a limiting factor for tree‐nesting vultures. Tree availability was found to greatly exceed nesting needs for African vultures and tawny eagles. We thus conclude that on a landscape scale, tree availability is not a limiting factor for any of the species considered here (white‐backed, lappet‐faced, white‐headed vultures and tawny eagles).}, number={1}, journal={JOURNAL OF AVIAN BIOLOGY}, author={Kendall, Corinne J. and Rubenstein, Daniel I. and Slater, Pamela L. and Monadjem, Ara}, year={2018}, month={Jan} }
