In order to assess the role of exclosures for biodiversity conservation, we collected vegetationdata from a young and an older exclosure using a systematic sampling design and contrasted the results with thoseobtained from an adjacent open grazing land. The stand density of all woody plants in the young exclosure was587 ha-1 and 1022 ha-1 in the old exclosure, while it was only 180 ha-1 in the open area. Sorensen’s similaritycoefficient indicated considerable dissimilarity in the species composition of vegetations between the exclosuresand open area. As exclosures mature, woody plant cover and species richness increased while herbaceous plantcover decreased. A total of 133 species representing 107 genera and 45 families were recorded from the studyarea where twenty species were recorded common to the exclosures and open grazing land. The Shannon diversityindex was highest (3.66) in the old exclosure and lowest (2.03) in the grazing land. In general, the result revealedthat management influenced the vegetation density richness and diversity. The study showed that area exclosuresplay potential role in enhancing the recovery of vegetation diversity of degraded areas.Key words: Free grazing, Vegetation diversity, Exclosure ages
