Abstract : The study was conducted to measure species diversity and habitat preference of amphibian fauna in Gulmi district, Nepal, from March 2016 to July 2018. The objectives of the study were to: (i) examine the richness and abundance of amphibian species in Gulmi district (ii) evaluate amphibian inventory of species and diversity (iii) compare the assemblage composition of different habitats. Data were collected by quadrate and pitfall sampling method. In total, 674 individual amphibian species belonging to 4 families, 9 genera and 12 species were recorded. The richness of amphibian species in riparian habitat (S= 11) was higher in number compared to the richness of the forest (S=3). Shannon-Weiner diversity index (H´) was 1.842 in agricultural field and 2.012 in riparian, whereas Simpson’s diversity index (λ) were 0.789, 0.815 in agricultural field and riparian habitat, but lower (0.613) in forest. Margalef’s, Menhinick’s and Brillouin index (HB) diversity indices salso showed higher diversity in riparian and lower in forest. Comparison of relative abundance and equitability index/Pielou evenness (J) of individuals among the species showed that species diversity of agricultural field (0.359) and riparian (0.336) habitat were abundant and numerically similar to the other habitats. Among habitats, abundance was greatest in the riparian with 286 (42.43%) followed by agricultural fields with 203 (30.11%) individual amphibians. The lowest amphibian abundance was documented in forest with 21 (3.11%) individuals. The presence of exclusive species in forest and wetland reinforces the importance of preserving different habitats for the maintenance of richness and diversity of local species.
