英文摘要 | Relict vegetation in the Jahlmanal watershed is sparsely and scantily distributed on forest land. Farmers maintain tree species (Salix spp., Populus spp., Hippophae rhamnoides) on the boundaries of terraced agriculture fields to meet the fodder and fuel wood requirements. Juniperus macropoda was found in relict forest patches in sparse and stunted conditions. The density of Salix fragilis was 3340 trees ha(-1) under agroforestry and 5520 trees ha-(1) under forestry. The density of J. macropoda was 4200 tree ha(-1) in natural forest followed by 700 tree ha(-1) in agroforestry and 160 tree ha(-1) in managed forestry systems. The agroforesty system of the watershed consists of 30% trees, 35% small trees and 35% shrubs species. Shrubs contributed the highest density with 59.1% of the total, followed by density of trees (29.5%) and small trees (11.3%). Trees contributed highest basal area in all the three systems, i.e., agroforestry, forestry and forest. The relict forest patches are subjected to deforestation due to anthropogenic pressure, hence in-situ and ex-situ conservation are required. Efforts are needed for plantation of ecologically suitable multipurpose tree species with indigenous species in the watershed. Technological interventions are also required to improve the quality and resistance against drought and climate change. |
