dc.description.abstractDistribution of Woody Vegetation along altitudinal ranges from Abay Gorge to Choke Mountain was conducted in East Gojjam Zone of Amhara Regional State, North West Ethiopia, with aim of assessing floristic composition, species diversity and structure of woody plant species in the study area. Systematic line transect sampling method was applied to collect woody vegetation data. Accordingly, 56 quadrats each with 400 m2 (20 m X 20 m) at a distance of 50 m. a. s. l. along a transect line for tree and shrubby species and subquadrats of 5 m X 5 m within the main quadrats were laid to record saplings and seedlings of woody plants and soil sample. Vegetation classification was performed by using R Software packages. Four clusters were identified and designated as local plant community types. Each community was named after two or three of the dominant tree or shrub species in the group. Shannon-Wiener diversity index was used to compute species richness and evenness of the communities. Ecological dissimilarity of communities was determined by Euclidean distance. CCA was used to correlate pH and altitude, while FSO was used to correlate environmental factors. DBH, Density, Frequency and IVI were computed to describe the structure of vegetation. A total of 120 woody plant species in 90 genera and 48 families were identified. Fabaceae and Asteraceae were the most dominant families with 16 and 14 species and with 11 and 10 genera each respectively. Shrubs were the dominant life forms. Thirteen endemic species were recorded, from which 4 are new records for FEE. Altitude and soil pH have great impact in vegetation distribution. Future research directions and recommendations were suggested for the sustainable utilization of the vegetation.
