Abstract
A survey on the diversity, abundance, and habitat association of small mammals in Wenchi Highland, central Ethiopia, was carried out from August 2019 to January 2021. Small mammals were trapped at six different habitats (Hagenia Woodland, Erica Scrub, Qibate, Lakeshore, Erica, and Albesa Forests) using Sherman and snap traps in standard trapping grids. A total of 937 rodents belonging to 12 species (Arvicanthis abyssinicus, Desmomys yaldeni, Mastomys natalensis, M. awashensis, Stenocephaylemys albipes, Lophuromys flavopunctatus, L. brevicaudus, L. chrysopus, Dendromus lovati, Lophiomys imhausi, Graphirius murinus, and an unidentified murid rodent), and 22 insectivores belonging to 3 species (Crocidura bailey, C. fumosa and C. olivieri) were recorded. Hystrix cristata and Tachyoryctes splendens were also recorded through indirect evidence. About 52.9% of the identified small mammals were endemic to Ethiopia. A significant variation was observed in the captures of small mammals. The capture rate was higher in live traps (23.85%) than in snap traps (8.26%). The diversity and composition of small mammal species varied among habitats. The highest species diversity (H’=1.656) was recorded in Albesa Forest, while the lowest was in Erica Scrub (H’=1.409) and Qibate Forest (H’=1.407). However, after controlling for sampling effects, species diversity was the highest in the Erica Scrub (Fisher’s alpha=2.128) and the lowest in the Lakeshore Forests (Fisher’s alpha=1.318). The highest number of individuals was recorded in Lakeshore Forest (27.73%), whereas the lowest was in Erica Forest (3.96%). Mastomys natalensis (30.86%) and S. albipes (27.82%) were the two most abundant species, whereas L. imhausi (0.1%) was the least abundant one. Wenchi montane forests are essential homes for unique small mammals that need urgent conservation actions.
