Terrestrial medium and large-sized mammalian species diversity in Michole Community Protected Forest, southern Ethiopia.

The study on medium and large-sized mammalian species' diversity and distribution is important for conservation efforts in the different protected areas of Ethiopia. The present study was intended to investigate the species diversity of medium and large-sized mammalian fauna between October 2019 and July 2020 in Michole Community Protected Forest, southern Ethiopia. The study was conducted by stratification of the study area into three habitat types: riverine forest (3.37 km²), woodland (4.14 km²), and grassland with scattered trees (2.33 km²) based on the vegetation cover. A diurnal transect survey method was implemented to record the mammalian species diversity. A total of 18 representative sample transect lines (six in riverine forest, four in grassland with scattered trees, and eight in woodland habitats) that varied in length and width were used. A total of 17 species of medium and large-sized mammalian species were identified and recorded in the study area. As a result, the orders Carnivora and Primates have the greatest abundance, while the order Lagomorpha has the least. Anubis baboon (Papio anubis) was the most abundant species (15.14%), followed by Spotted hyena (Crocuta crocuta) (12.98%), Crested porcupine (Hystrix cristata) (12.51%), Vervet monkey (Chlorocebus aethiops) (10.35%), Common duiker (Sylvicapra grimmia) (8.80%), and Giant root-rat (Tachyoryctes macrocephalus) (8.65%). The distributions of mammals among the three habitat types were comparable. The riverine forest harbored the highest mammalian diversity index (H' = 2.35) followed by the woodland (H' = 2.32), and the grassland with scattered trees (H' = 2.30), respectively. The greatest species similarity was recorded in woodland (0.902). The study area harbors considerable mammalian species that are threatened by interacting anthropogenic factors. So, urgent conservation measures by concerned sectors are needed to safeguard these animals and their habitat.
