Understanding the composition, abundance, and habitat associations of mammalian species is crucial for their effective conservation and habitat management. The study was aimed at filling the knowledge gaps regarding mammalian diversity and distribution in the Yegof National Forest Priority Area and its surrounding habitats. Accordingly, we assessed the species composition, abundance, and habitat association of mammals in the study area from July 2021 to April 2022. Based on plant physiognomy, the study area was categorized into five habitat types: natural forest, wooded grassland, plantation, bushland, and open grassland. A total of 13 mammalian species were recorded through line transect surveys. The order Primate was the most abundant taxonomic group accounting for 68.9% of the total mammals recorded. Among the recorded species, was the most numerous, accounting for 32.77% of the total, followed by (19.95%) and (16.15%). The abundance of mammals varied significantly across different habitats. During the dry and wet seasons, 57.7% and 42.3% were recorded, respectively. A statistically significant seasonal difference in abundance was observed. More than half (56%) of the species recorded were common to all five habitat types. The highest species similarity index (SI = 0.95) was observed between natural forest and wooded grassland. The study reveals considerable mammalian diversity in the study area, accompanied by notable variations in abundance across different habitats and seasons. However, the study area faces conservation challenges, including deforestation, illegal hunting, and human-wildlife conflict, which threaten population sustainability. Addressing these threats is essential to ensure the long-term survival of mammal species.
了解哺乳动物物种的组成、数量及其栖息地关联对于其有效保护和栖息地管理至关重要。本研究旨在填补叶戈夫国家森林优先区域及其周边栖息地有关哺乳动物多样性和分布的知识空白。因此,我们在2021年7月至2022年4月期间评估了研究区域内哺乳动物的物种组成、数量及其栖息地关联。根据植物外貌特征,研究区域被划分为五种栖息地类型:天然林、树木繁茂的草原、人工林、灌木丛和开阔草原。通过样线调查共记录了13种哺乳动物物种。灵长目是数量最多的分类类群,占记录到的哺乳动物总数的68.9%。在记录的物种中, 数量最多,占总数的32.77%,其次是 (19.95%)和 (16.15%)。不同栖息地的哺乳动物数量差异显著。在旱季和雨季分别记录到57.7%和42.3%。观察到数量存在统计学上的显著季节差异。记录到的物种中超过一半(56%)在所有五种栖息地类型中都有。天然林和树木繁茂的草原之间的物种相似性指数最高(SI = 0.95)。该研究揭示了研究区域内存在相当丰富的哺乳动物多样性,不同栖息地和季节的数量也存在显著差异。然而,研究区域面临着保护挑战,包括森林砍伐、非法捕猎和人兽冲突,这些都威胁着种群的可持续性。应对这些威胁对于确保哺乳动物物种的长期生存至关重要。
