A camera trap assessment of the forest mammal community within the transitional savannah‐forest mosaic of the Batéké Plateau National Park, Gabon.

Monitoring populations in areas of ecological transition is crucial to understanding species distributions, but also a critical conservation tool. We used camera trapping to investigate the forest mammal community in the Batéké Plateau National Park (BPNP) in Gabon, a transitional landscape that experiences severe poaching. We compiled a species inventory, investigated group sizes and activity patterns of observed species, and conducted an initial test to evaluate whether ecological gradients within this landscape influence species occurrence. Based on 6612 images and videos recorded at 40 locations during 5,902 camera days, we identified 31 mammal species, including eight classified as threatened according to the IUCN. We detected lion (Panthera leo, Linnaeus), which was thought to be extinct in Gabon, and mandrill (Mandrillus sphinx, Linnaeus), for which BPNP was thought to be outside of their natural range. Our findings suggest that BPNP supports a low species richness compared to more forested protected areas. We found no changes in species composition of the forest mammal community with increasing distance from the continuous Gabonese rainforest, but a potential decrease in abundance for some species. Continued survey efforts need to be combined with detailed ecological data collection and effective law enforcement in the region. [ABSTRACT FROM AUTHOR]
