The study in wetland vegetation of the area was conducted between October 2005 and June 2006. The vegetation and environmental data were collected from 88 quadrats (during wet season) and 77 quadrats (during dry season) from the six study sites. The Purpose of the study was to investigate floristic composition and diversity of wetland vegetation in the area. The major issues addressed include floristic diversity, vegetation description, community type identification, site diversity, measurement of aboveground biomass and wetland plant inventory. During the study, the percentage cover abundance of each species was estimated and later converted into modified Braun-Blanquet 1-9 scale. Clipping of all the aboveground vegetation was carried out in 1 m2 plot size, which is placed at the center of each 4 m2 quadrat, used for plant community description. Some environmental variables and disturbance scale was recorded for each site. A total of 69 and 56 plant species representing 28 and 27 families were identified during wet and dry seasons respectively. The families Cyperaceae, Poaceae and Lamiaceae were represented by the highest number of species. All the vegetation data were analyzed with SYNTAX-2000, computer program. Three and four reasonable plant community types were obtained and described. The resulting clusters were interpreted as community types and were given names after two dominant plant species. Shannon-wiener diversity index was employed to analyze species diversity in the plant community types and the study sites. The clusters of stands were found to show variation due to differences in altitude, moisture contents, and other site conditions. Recommendations for the sustainable utilization of the vegetation resources at the study sites are provided.enBiologyThesis
