Abstract:
Land degradation is widespread and a serious threat affecting the livelihoods of many. It was found that the prospect of restoring degraded lands is technically promising using area exclosure. Data on vegetation were gathered from 90 quadrants from exclosures of different ages and 30 from adjacent free grazing lands. The seedling and sapling inventory were done by two subplots of 2 x 5 m established at the beginning and the end of the baseline on opposite sides of the main plot. A total of 27 sapling species belonging to 16 families was recorded. Sapling density ranges from 1000 to 21,000 saplings per ha (3197 ± 720). Fabaceae is the dominant family in the sapling. Similarly, a total of 17 seedling species belonging to 11 families was recorded. The overall seedling density ranges from 1000 to 12,000 seedlings per ha (2897 ± 980). Like sapling, fabaceae is the dominant family in the seedling. Analysis of seedling and sapling density indicated that both exclosures and free grazing areas were found to be dominated by few species. Local communities’ participation, incorporation of indigenous ecological knowledge, is crucial for long-term success of rehabilitation activities.
