Abstract
AbstractThis study investigates the response of large mammal populations to human‐induced modifications in the Omo‐Shasha‐Oluwa Forest Reserves landscape. The impact of habitat alterations on species diversity and distribution remains poorly understood in this region. Over four seasons from May 2017 to April 2019, 52 sites were surveyed, revealing the presence of 12 large mammal species across six families. Maxwell's duiker exhibited the highest overall occupancy (0.897 ± 0.062), while the Forest elephant had the lowest (0.115 ± 0.043). Forest buffalo experienced the greatest increase in site occupancy (0.290 ± 0.076 to 0.358 ± 0.098), whereas the Mona monkey saw the most significant decrease (0.713 to 0.651). The study employed single‐species, multi‐season occupancy modelling, predicting colonisation and extinction events solely for the civet (ϒ = 0.347 ± 0.154; ε = 0.041 ± 0.031) and Red river hog (ϒ = 0.158 ± 0.098; ε = 0.098 ± 0.059). The likelihood of Civet cat and Red river hog colonisation increased with distance from the nearest settlement. These findings enhance our understanding of habitat characteristics influencing large mammal distribution, offering valuable insights for the conservation of these species in forest landscapes.
