Diversity index of landscape
Species index of diversity confirmed that there is a variant in species range among the habitats. As an example, grassland and dense forest have the highest species range (H′ = 2.198; H= 2.165), respectively, whilst the least species variety becomes recorded from the plants’ land (H′ = 2.037). The species index of the diversity of the examined location confirmed better species richness (H = 2.296; 1-D = 0.8406) than to the observe conducted by Qufa and Bekele (2019) inside the Lebu natural included wooded area, Ethiopia (H = 2.119; 1-D = 0.8167) and less than look at conducted through Gebo et al., (2021) in the Faragosa-Fura landscape, Gamo Zone, Southern Ethiopia (H=2.56; 1-D=0.8968). In addition, research performed by Kasso and Bekele (2017) confirmed that the variant in the range and abundance of mammal species among unique habitats is associated with the quality of the habitat, preference of the species, availability of food assets, dense forest cover, and water is probably contributed to better species richness. Our finding is inconsistent with the study carried out by way of (Geleta and Bekele, 2016; Gebo et al ., 2021), in which they obtained a better species range in the grassland and herbal wooded area. Those variations might be due to human stress on the Arjo Diga conservation forest earlier than it became protected.
