Abstract:
Gelawoldie Community Forest is found in Yilmana Densa District,west Gojjam Zone. It provides diverse ecosystem services to the surrounding community. However, there are no data about the 59 woody species status of the forest. Therefore, the objective of the study was to determine the woody plant species diversity, structure and regeneration status of the forest and to identify threats of biodiversity loss. Six transect line laid down at 100m distance to collect woody vegetation data. Thirty two quadrate each with 400 m2 (20 m X 20 m) at a distance of 50 m were located along the transect lines for tree and shrub species. Sub plots of 5 m X 5 m within the main quadrate were laid to record saplings and seedlings of woody plants. A total of 59 woody species in 49 genera and 38 families were identified from the forest. From the total woody plant species, 21 (35.5%) were trees 30 (50.8%) were shrubs and 8 (13.5%) were woody climbers. Of all the families, Fabaceae and Asteraceae were the most dominant, each contributing 5 species (8.77%) of the total. The forest had the Shannon- Wiener diversity index (H`) of 3.787 and evenness of 0.936. A vegetation comparison of Gelawoldie community forest with other related forests in Ethiopia revealed relatively high vegetation similarity with Yimrhane forest with Sorensen’s similarity coefficient of 68%. The analysis of DBH and height distribution of the forest showed normal inverted J-shaped pattern indicating that most of the populations found in lower diameter and height class respectively. The first two lower height classes contribute 75.63%. The total mean basal area of the selected tree species in the community forest calculated was 93.8 m2ha1 and the total important value index of the selected plants in the community forest was 291.75. The population structure of the study forest indicated that there are more seedlings than saplings which could be attributed to factors that affect the seedlings from reaching saplings. These factors included human interventions and browsing by animals. The area was seriously deforested due to unwise use of the surrounding community. Thus the forest needs urgent government intervention to conserve the forest by the community and ensure the continual existence of the species.
