Woody Plant,Composition, Structure And Regeneration Status Of Gura Tiregni Forest In Gida Ayana Woreda, East Wollega Zone, Ethiopia

Abstract

One of the moist montane forests in Ethiopia's East Wallaga Zone is the Gura Tiregni Forest, which is home to a wide variety of animal and plant species. Thus, this study was conducted on Woody Plants, Composition, Structure and Regeneration Status of Gura Tiregni Forest in Gida Ayana Woreda, East Wollega Zone, Ethiopia. To achive the basic research questions the researcher was used Systematic sampling method to collect vegetation data. Quantitative data was descriptively analysed through descriptive statistic like frequencies and percentages used to summarize and interpret the research findings 110 species and 53 families. The results of the study show that, from these species, 70 (57%) were trees, 18 (28%) werelianas, 16 (13%) were shurbs and 2(2%) were trees/shrubsBased on their relative importance value index, 26.92% of tree species were selected as dominant species in the woodland vegetation. Erythrina brucei Schweinf.and Salix mucronata Thunb. (S. subserrata Willd) was the most abundant species in seedling stages with 174 and 150 individuals respectively. Their sapling stages are also 81 and 88 individuals respectively. The result from the analysis showed communities three and four shared about 50%or the highest of allsimilarity in species composition. Generally, the structural analysis of vegetation revealed that, the density of woody species in the forest as well as the selected dominant species was decreased with increasing DBH from lower to higher DBH classes, which implied the predominance of small-sized individuals in the lower classes, indicating good recruitment of the forest.
