Abstract :

Degraded hillsides have been allocated for tree planting to find land for farmers while improving their lives. We assessed the contribution of tree growing on re–vegetation of degraded hillsides. Vegetation inventories were carried out from randomly fixed sample plots. Independent samples t–test was run on density, richness, diversity indices and volume of woody species between managed and disturbed hillsides. ANOVA was also used to examine age and site effects among hillsides. The study showed that management increased tree density by a factor of 4.1 over disturbed hillsides (p
