Complete documentation on the status of mammals is indispensable for appropriate conservation measures in protected areas. However, there is inadequate information on mammalian resources in the ecosystem of Gibe Sheleko National Park (GSNP). Thus, the study aimed to assess species diversity, abundance, and habitat association of medium- and large-sized mammals in GSNP. We stratified the study area into five dominant habitat types, namely dense forest, wooded grassland, grassland, riverine forest, and farmland habitat types based on land cover and vegetation structures and further employed stratified random sampling technique across each habitat type. The sample transects covered 20% of the study area. Transect width ranged from 50 m to 400 m based on vegetation cover and visibility of mammals. The main data were collected via direct observation. Data were analyzed via chi-square test and species diversity indexes. We recorded the total of 20 mammals species' those belong to 10 families of which 8 species were large-sized and 12 species medium-sized mammals. There were two IUCN vulnerable species, namely and , and two globally near-threatened species, particularly and in the study area. Dense forest held the highest species diversity of medium- and large-sized mammals (' = 2.28) with the highest evenness index ( = 0.84). Riverine forest had the least diversity with uneven population distribution. was the most abundance species, whereas was the least abundant in the study area. GSNP is home for threatened and spectacular mammals species'; hence, an appropriate conservation measure is mandatory to keep existing mammals species'.
完整记录哺乳动物的状况对于保护区采取适当的保护措施至关重要。然而，关于吉贝谢莱科国家公园（GSNP）生态系统中哺乳动物资源的信息不足。因此，本研究旨在评估GSNP中大中型哺乳动物的物种多样性、丰度和栖息地关联。我们根据土地覆盖和植被结构，将研究区域划分为五种主要栖息地类型，即茂密森林、树木繁茂的草原、草原、河岸森林和农田栖息地类型，并在每种栖息地类型中进一步采用分层随机抽样技术。样本样带覆盖了研究区域的20%。样带宽度根据植被覆盖和哺乳动物的可见性在50米至400米之间。主要数据通过直接观察收集。数据通过卡方检验和物种多样性指数进行分析。我们总共记录了20种哺乳动物，它们属于10个科，其中8种是大型哺乳动物，12种是中型哺乳动物。研究区域有两种世界自然保护联盟（IUCN）易危物种，即 和 ，以及两种全球近危物种，特别是 和 。茂密森林中大中型哺乳动物的物种多样性最高（' = 2.28），均匀度指数最高（ = 0.84）。河岸森林的多样性最低，种群分布不均衡。 是研究区域中数量最多的物种，而 是数量最少的物种。GSNP是濒危和壮观的哺乳动物物种的家园；因此，必须采取适当的保护措施来保护现有的哺乳动物物种。
