Woody species composition and diversity of riparian vegetation along the Walga River, Southwestern Ethiopia

Fifty quadrats of 10m X 50m were laid at 500m interval through systematic sampling method along river line. Vegetation height (>2m) and DBH (>2.5m) of only tree species were measured, and altitude, ecological disturbance such as, grazing intensity and human impacts were included as main environmental variables at each of the sampled plots.

The data was analyzed using different R statistical packages. Ninety-nine woody vascular plant species belong to 81 genera and 45 families were recorded in Walga riparian vegetation. Only 10% of species were endemic to Flora area.
