Abstract
A comparative study of vegetation data of Menagesha Suba State Forest between 1980 and 2006 in the central plateau of Ethiopia was conducted. The forest represents a dry evergreen Afromontane Forest. The vegetation data were correlated in previously laid 50 quadrants, each with 20 m x 20 m systematically. The presence and absence of all shrubs and trees in the stands were recorded. Density values for trees and shrubs were registered. Soil pH, altitudes, slopes and aspect were measured. The vegetation data were analyzed using Association Analysis and TWINSPAN. Results of the Association Analysis were used for matching the species used as characteristic in the determining the community types in the previous and the current study. TWINSPAN outputs are used to identify vegetation types using polythetic hierarchical approach. According to the outputs of TWINSPAN Analysis six clusters were recognized. These are: 1. cuprussus lusitanica, 2. Myrsine africana – Erica arborea, 3. Myrsine africana – Olea europaea, 4. Olea europaea – Sideroxylon gillettii, 5. Dovyalis abyssinica – Allophyllus abyssinicus, 6. Lantana trifolia - Juniperus procera . Structural analysis of the forest showed dominance of small sized species.
