Floristic Composition Of Woody Vegitation With Emphasis To Ethnobotanical Importance Of Wild Legumes In Laelay And Tahtay Maichew Districts Central Zone Tigray Ethiopia

This study was focussed on the floristic composition of woody plants and ethnobotanicalrnimportance of legumes in Laelay and Tahtay Maichew, central zone, Tigray. To study woodyrnplants study sites were selected via preferential sampling in protected, mountains and degradedrnwatershades following survey. At the end of the day, sixty (60) plots were laid down. Interviewsrnwere conducted with informants and field observations were made to collect Ethnobotanicalrndata. Statistical tools like hierarchial cluster analysis and Shannon-Wiener diversity index werernused for vegetation data analysis. Preferential ranking was also applied for Ethnobotanical datarnanalysis. As a result 57 woody species and 8 herbaceous legumes were identified. The mostrnspecies rich family was Fabaceae with 13 species. The result of cluster analysis show that, fiverncommunity types with distinct species number and the community types found in protected areasrnhave more species than unprotected ones. The prefertial ranking for ethnobotanical study ofrnlegumes show that, widely used plants for food and farm implements are Ziziphus spina-christirnand Acacia lahai respectivelly. The traditional medicinal knowledge is acquired more fromrnparents in the area. The major threats of woody plants are cutting, continuous cultivation andrnovergrazing Woody. Meanwhile plantations are the main conservation practices applied in thernareas to conserve and facilitate regeneration of woody plants.rnKEY WORDS and PHARASES: Woody plants, cluster analysis, Ethnobotany, legumes,rnplantation
