Effect of exclosure on woody species diversity and population structure in comparison with adjacent open grazing land: the case of Jabi Tehnan district north western Ethiopia

Land rehabilitation by area exclosure was the fastest and moderate approach of recovering degraded sites. However, the effect of exclosure on woody species parameters in Jabitehnan district, north-western Ethiopia has not been investigated. Therefore, the current study was conducted (i) to assess an...
