Species richness
The types of mammals recorded in the current study were higher than those of mammals with medium and large mammals in different areas. For example, according to Geleta and Bekele (2016) reported that 15 species of mammals were recorded in the Wacha reserved forest, Western Ethiopia, with direct and circumstantial evidence. Moreover, Woldegeorgis and Wube (2012) and Abdu et al ., (2020) recorded 14 mammals species from the Yayu forest in southwestern Ethiopia and consequently the Birbir Protected Forest, Western Ethiopia respectively. However, small (12) mammals have recorded inside the Mengaza network woodland, Gojjam, Ethiopia (Getachew & Mesele, 2018). In contrast, the total number of medium and large-sized mammalian species (19) recorded during the present study was relatively low compared to areas of different protection levels across the country and elsewhere. For instance, 28 species of medium and large mammals were recorded from Dhati wolel National Park (Rabira et al., 2015), 23 species from Baroye Control Hunting area (Dereje et al., 2015) and Borena Saint National Park (Alemu, 2010), 20 species from Alatish national park (Girma & Afework, 2008) and 22 species from Fragmented Ruminant Forest around Asela town (Kasso & Bekele, 2017) and 21 species from the Faragosa-Fura landscape, Gamo Zone, Southern Ethiopia (Gebo et al ., 2021).
Similarly, research performed in distinctive countries revealed that the medium and large‐sized mammals recorded had been higher than the end results bought from the present study. Some of the studies amongst others include, Melo et al ., (2015) recorded 33 mammals species in Brazil; Botelho et al ., (2012) recorded 27 species of medium to large-sized mammals in the Humaitá wooded area protected, inside the south West of Amazonia; Campos et al .,( 2013) observed 23 mammals’ species in Brazil and Oliveira an Hannibal, (2017) recorded 22 species of deciduous wooded area, with leafy bushes in Brazil.These differences may be due to climate change, variation in mammal’s group composition, variation in vegetation structure, human impact due to deforestation, agricultural expansion, coal production, and the increase in domestic livestock and other environmental factors. The current study area, however, was not given due attention to biodiversity conservation and landscape restoration within the beyond decade.
In addition, as shown in the paragraph above, the wide variety of mammals recorded all through the cutting-edge determine about it used to be additionally in contrast with a few different research performed in Ethiopia and elsewhere. Therefore that, the relative abundance of food resources, coverage of green vegetation, and the presence of water (Dhidhessa River) may also be key factors in controlling their abundance and richness of biodiversity in the current lookup area. Recent research has shown that endangered species round the world such as Panthera Leo and Panthera pardus were recorded in the area, indicating the area has practicable for biodiversity conservation.
