3.3| Species diversity and evenness
The highest diversity of mammals was recorded from scrublands followed
by natural forests in the area. But, only a single species was seen in
the bar land habitat, as a result no species diversity here. Medium and
large sized mammalian similarity was high between scrublands and natural
forests (SI=0.62), followed by scrubland and bar land habitats
(SI=0.25). But, there was no mammalian species similarity between
natural forests and bar land (SI=0.00). On the other hand,the higher and
lower evenness of the mammalian species was recorded in scrublands(E =
0.826) and natural forest (E = 0.636). The highest Simpson’s index (1-D)
of mammalian species was recorded from the scrublands (0.803) and the
natural forests habitat had a lower diversity (0.647).The overall
species richness of Amoro forest was 12, and Shannon–Wiener Index
values were low (H′ = 1.666) whereas the Simpson’s index of diversity
showed the highest species diversity (0.761) in the study area (Table
3).
