Abstract

Aim: The objective of this study was to survey the species composition, relative abundance and to determine major threats of medium and large-sized mammals in Amoro Forest. Method: Linetransects surveying and indirect surveys method (including fresh tracks, scats, hair, spines and burrows) were used to survey mammalian diversity. A survey was conducted in the early morning from 6:00 to 10:00 and late afternoon from 16:00 to 19:00. Key interview and direct site observationswere carried out to assess the major threat of mammals in the study area. Results: A total of 12 species of medium and large sized mammals belonging to sex orders and eight families were recorded. Porcupine (Hystrix cristata), Vervet monkey (Chlorocebus aethiops) and Olive baboon (Papio anubis) were among the medium-sized mammals while, Spotted hyena (Crocuta crocuta),Leopard (Panthera pardus) and Common duiker (Sylvicapra grimmia) were among the large sized mammals observed in the study area. Shannon–Wiener Index values were low (H′ = 1.666) whereas, the Simpson’s index (1-D) of diversity showed the highest species diversity (0.761) in the study area. Illegal logging of trees; overgrazing, agricultural activities and human-wildlife conflicts were the foremost threats in the area. Conclusion: Species richness and evenness were varied from habitat to habitat in Amoro forest. Land degradation anddifferent anthropogenicactivities were common threats for the mammals in the study area. Community participation and awareness creation is very important to limit the impact of anthropogenic activities threatening wildlife.
