Abstract Background: The species composition, relative abundance and distribution of rodents were studied in Wof-Washa Natural State Forest, Ethiopia from December 2016 to May 2017 during dry and wet seasons. A total of 49 Sherman live traps were set per grid at 10 m intervals in permanent 4900 m2 (70mx70m) live trapping grids established in intact forest, disturbed forest, Erica woodland, plantation forest and Farmland habitats. Result: A total of 621 individuals of rodents were captured in 2,560 trap nights by using both live traps and snap traps. Seven species of rodents in family Muridae were recorded. Out of the total rodents caught in the study period, Stenocephalemys albipes, Pelomys harringtoni and Lophuromys flavopunctatus are endemics to Ethiopia. Plantation forest had the highest mean trapping success whereas the lowest trap success was in the Erica woodland. The distribution of rodent species was significantly differed (P<0.05) among studied habitats. Higher trap success was recorded in dry season (26.2) than the wet season (24.4). The highest value of Shannon index was recorded in plantation forest (H’ = 1.82) followed by farmland habitat (H’ =1.67) during the wet season and the lowest value was observed in the intact forest (H’ = 0.67) and Erica woodland (H’ = 0.67) during the dry season. From the total catch, adults comprised 260(41.9%), sub-adults 248(39.9%) and juveniles 113(18.2%).Conclusion: The present study provides the first valuable demonstration on the species composition, relative abundance and distribution of rodents in the WWNSF. Further monitoring and inventory of small mammals is warranted to document and conserve the different endemic and endangered rodent species to designing important biodiversity management plan in the area.

A study was carried out to evaluate the species composition and relative abundance of bird species of the natural and plantation forest of Ogbese Forest Rserve, Ekiti State. The study was conducted from April, 2010 to February, 2011 covering both wet and dry seasons. Sample sites were stratified based on the vegetation types and transect count techniques was employed for the evaluation. A total of 52 bird species consisting of 47 resident and 5 immigrant species was recorded. The species composition of birds during the wet and dry seasons was not significantly different. The natural forest vegetation had the highest species diversity and evenness. The relative abundance score of species during the Wet and dry seasons was variable in both habitats. The result of this study has shown that the natural and plantation vegetation types of Ogbese Forest Reserve, Ekiti State. The heterogeneity of flora species in the natural forest compared to the plantation forest might be responsible for the variation. The management of birds in the reserve should take cognisance of the vegetation types for effective conservation of bird species which are resident in the reserve.

Introduction. Ethiopia is one of the most avifauna rich countries in Africa. Avifaunal surveys are required to inform conservation decisions and enhance land management for biodiversity. Avifaunal surveys from Ethiopia are lacking. This study examines species composition, relative abundance, and habitat association of avian fauna in Zegie Peninsula forest patches and associated wetlands from surveys carried out from August 2018 to March 2019, covering both the wet and dry seasons. Data Collection. Forest, shrub, lakeshore, and wetland habitats were identified as ecologically relevant habitats in the study area for data collection. Data were collected using point count and line transect methods, for 24 days in total for both seasons in the morning and afternoon. Results. A total of 96 species of birds were identified during the whole study period. Out of the total, 40 species were observed during the wet season, 13 during dry and 43 species in both seasons. There was significant variation of species distribution among habitats. During the wet season, the highest species diversity was recorded in the wetland habitat followed by forest habitat. During the dry season, avian diversity was the highest in the lakeshore followed by wetlands. The highest evenness was observed in the shrubland during both the wet and dry seasons. During the wet season, the highest species similarity was recorded between wetland and lakeshore habitats, and during the dry season, the highest species similarity was recorded between forest and shrub habitats. Based on encounter rate data, 64 (66.66%) of the avian species were uncommon. Conclusions. Compared to previous studies conducted in the study area, species diversity was lower. This might be due to various anthropogenic activities such as deforestation of trees for timber and cutting trees for firewood. Therefore, awareness creation should be given to the local community to reduce habitat destruction due to various human-induced factors.

Natural  stand changes in the forest reserve of Liedekerke were analysed during the  period    1986-1996, using a permanent grid of circular plots. The monitoring  concentrated on natural    changes in species composition, using stem number and basal area as  indicators, and changes    in spatial distribution and colonization capacities of trees and shrubs,  with special interest in the    competition between exotic and indigenous species. After only a decade of  monitoring important    natural changes in the woody layer were detected. The pioneer forest is  gradually maturing    through self-thinning processes and shifts in species composition. The  overall stem number    decreased with 33.6%, while the basal area increased with 20.9%. Birch (Betula pendula/    pubescens) and indigenous oak (Quercus robur/petraea) remained  dominant. More tolerant    exotic species, like red oak (Quercus rubra) and sweet chestnut (Castanea  sativa), are slowly    increasing their share in the species composition and expanding their  range. Pioneer species on    the other hand, like aspen (Populus tremula), willow (Salix  capreaicinerealaurita), alder buckthorn    (Frangula alnus) and  common (Alnus glutinosa)  and grey alder (A. incana),  strongly declined.    Black cherry (Prunus serotina) seems to be slowly invading the forest due to its  massive    natural regeneration. Strong competition may be expected especially from  rowan ash (Sorbus    aucuparia), which showed similar regeneration  and colonization capacities. Elder (Sambucus    nigra) dramatically extented its range, though  its share remains marginal. Beech remained absent    most probably due to the lack of mature trees in the vacinity of the  forest. Finally this    change detection allowed that general predictions could be made on the  future natural development    and composition of this forest reserve, which could serve forest management  decisions.
