Riparian vegetation which is an essential part of riverine ecosystems are highly disturbed and degraded over the world including in Ethiopia. The present study aims to examine the status woody species vegetation alongside of Huluka River. Total of 25 quadrant transects with 100 X 50m were laid out at every 1km distance perpendicular to the flow of the river. At the corners of all transects 10 × 10 m plots was used for the sampling of trees and plot size of 5 × 2 m that nested in the 10 × 10 m plot were used for sampling of shrubs and saplings. In each sample plot all tree species with height (≥2.5 m) and DBH (≥2.5 cm) were measured by using Suunto clinometers and calliper respectively, and all individual shrubs and sapling species were counted. Diversity indices such as Shannon diversity index (H'), evenness index (E), species richness (R), and Simpson diversity index (D) were calculated. A total of 25 trees species belonging to 21 families and 22 shrub species belonging to 19 families were recorded. 99% were indigenous, while the remaining was exotic species. Acacia abyssinica, Juniperus procera and Olea africana from tree species, and Carissa edulis and Maytenus arbutifolia from shrub were the most dominant species. Species diversity ranged between 0.43 and 2.47, whereas evenness ranged between 0.46 and 1.06. Species diversity and richness show increasing pattern from upstream of the river system (Dendi district) to the downstream of the river system (Ambo district), but it depends on the contiguous land uses i.e. riparian vegetation bordered with natural forests higher species richness and diversity, whereas those bordered with grazing land has lower species richness and diversity. The riparian vegetation along the river is highly converting to agricultural and grazing lands, and this results degradation of the vegetation.
