| Abstract | Forest restoration has brought increasing international attention, especially since the adoption of the UN’s Sustainable Development Goals and New York Declaration on Forests in 2015. However, there is little study on how management can improve natural regeneration capacity and reduce costs. This study investigated the species diversity, stem density, basal area, regeneration pattern and rate of S. robusta forest along with the costs of establishment of the nursery for seedlings establishment against the costs for managing forests for improving natural regeneration. The species diversity determined by Shannon Index, and species evenness value which was considerably higher in managed compared to unmanaged forest site. Although density, basal area varied by forest types; however, forest structure found J reverse shape in both forest sites. Based on Important Value Index and relative abundance S. robusta species was dominant in all layers of forest and density, basal area were higher compared to other species. Distribution pattern of S. robusta in managed site layers seedling (MI= 1.11) and sapling (MI=1.13) in managed was clumped (MI>1) and in unmanaged site seedling (MI=0.63) and sapling (MI=1) observed random and uniform respectively, which was different from managed site. We found that seedlings increased with increased in number of trees as positive correlation between mother tree and seedlings. This study suggests extending management strategies with effective management practices need to be adopted which directly enhance the natural regeneration and improve overall condition of forest. |
