Woody Species Composition, Diversity and Vegetation Structure of Dry Afromontane Forest, Ethiopia

摘要

This study was conducted in wanzaye natural forest, South Gondar, Ethiopia. The main objective of the study was to determine the species composition, diversity and vegetation structure analysis of wanzaye natural forest. A total of 75 quadrants or plots were used. Each sample plot covered an area of 400 m2 (20m x 20 m). For trees/ shrubs, all woody species with diameter at breast height (DBH) 2.5 cm and height 2 m were recorded in all plots. For the regeneration purpose, trees/shrubs species with diameter 2/sup?hasup-1/sup. Number of individuals with (DBH) 2.5cm and height 2 m was 482 trees hasup-1/sup?and for the regeneration it was (2916 individuals hasup-1/sup). Based on Importance Value Index (IVI) Ficus sycomorus (56%) followed by Dodonaea viscosa (31%) and Croton macrostachys (19%) was recorded. The overall diameter frequency distribution of woody species show inverse J- shape.
