Abstract
Wabero forest is one of the very few remnant moist evergreen montane forests in Southeast Ethiopia. However, basic data on vegetation structure and composition of the forest that could provide valuable information for possible conservation measures is lacking. The main objective of this study, therefore, was to investigate the woody species composition, vegetation structure and regeneration status of the forest. In the study 30 quadrants of 20 m by 20 m were used for woody species data and 5 m by 5 m for sapling and seedling in a nested form. The sample quadrants were laid down along transects at a distance of 300 m from each other. Diameters at breast height (DBH), basal area, frequency and importance value index were used for analysis of vegetation structure. In the study, a total of 47 woody plant species belonging to 43 genera and 33 families were recorded. The major families were Rubiaceae and Rutaceae each represented by four species followed by Sapindaceae, Moraceae and Oleaceae each represented by three species. The rest of the 28 families were represented by one or two species, only. The mean density of all the woody species recorded in the study site was 21,737 ha-1. Diospyros abyssinica, Podocarpus falcatus, Strychnos mitis, Celtis africana and Coffea arabica were found to be the most dominant and frequent species with the highest importance value index. Results of regeneration status of the forest, which was analyzed by comparing number of seedling and sapling with mature trees, revealed that the forest is under good regeneration status. Therefore, based on the results of the study, awareness creation and implementation of participatory forest management strategy is recommended in order to sustain the forest. Key words: Basal area, diameters at breast height (DBH), importance value index, Montane forest, woody species composition.
Highlights
Ethiopia is one of the tropical countries with highest floral diversity (Motuma et al, 2010)
1950‟s, the area covered by forest in Ethiopia estimated to be 9 million ha (16% of the land area) and in the 1980‟s; it was reduced to 3.6% and by 1989 to 2.7% (Gessesse, 2010)
A total of 47 woody plant species belonging to 33 families were identified in the 30 plots
Summary
Ethiopia is one of the tropical countries with highest floral diversity (Motuma et al, 2010). Between; 6,000-7,000 species of higher plants are estimated to exist in the country of which about 780-840 (12-13%) plant species are estimated to be endemic (Demel, 2001) These biologically rich resources of Ethiopia are vanishing at an alarming rate due to extensive deforestation. Even though several factors contribute for destruction of natural forests in Ethiopia, agricultural expansion is probably the dominant force (Mulugeta and Demel, 2006). This will result in the loss of biodiversity resources along with their habitats (Senbeta and Denich, 2006). Since forest serves as a source of food, household energy, construction and agricultural material, tourism and recreation values and medicines, its loss would have impact on the socio-economic setup of the communities (Hundera et al, 2007)
