dc.description.abstract	Chelya Aguat Wuha and Liminch Tach Jufi Wetlands are located at the periphery of durbete town in South Achefer Woreda, north western Ethiopia. This study investigate the ecological status of these wetlands and examine the scale of the human disturbances that the local conductivity (  S/cm), pH, dissolved oxygen(mg/l), turbidity (NTU) in-situ and nitrate and phosphate in ex-situ were measured for communities might impose on them. Temperature ( o C), assessing ecological condition of wetlands. Macrophytes data collected using transect sampling method. Sixty reliv’e sites selected randomly every ten (2mx2m) on the eleven transects. six line transect counting sites were used for counting birds by naked eye and Binocular. Household survey, focus group discussion, field observation and key informant interview were made. Descriptive statistics were used to analyze data. Relatively the value of pH, conductivity and turbidity higher in the Chelya Aguat Wuha wetland than Liminch Tach Jufi wetland, however, the value of all physico chemical variables measured were inline with standards. Thirteen and fifteen macrophyte families in Chelya Aguat Wuha and Liminch Tach Jufi wetlands recorded respectively. Totally thirty seven genera and seventeen macrophyte families were recorded. The highest diversity index(2.67) and evenness (0.84) of macrophyte at Chelya Aguat Wuha was recorded during wet season and the least diversity index(1.61) and evenness(0.65) was recorded during the dry season in Liminch Tach Jufi wetland. Species composition of birds during the wet and dry seasons was significantly different (P<0.05) but insignificant difference between studied wetlands (P>0.05). Chelya Aguat Wuha was more diverse bird species than Liminch Tach Jufi wetlands. The biological and environmental condition was similar and suitable habitat for fauna and flora, however, chelya Aguat Wuha and Liminch Tach Jufi was least and mid disturbed wetlands respectively by human activities. Draining for small scale irrigation in Liminch Tach Jufi, expansion of farming, overgrazing, over exploitation and eucalyptus plantation were major threats.
