摘要

The ecosystem of Doon Valley is greatly influenced by open cast mining for limestone, marble, dolomite and phosphorite, etc. The mining on the watershed has resulted in denudation of hill slopes, loss of vegetation and soil cover, decrease in soil moisture retention, nutrient holding and water recharging capacity and thereby changing the total hydrological picture of the region. Land degradation in the region has become the most important problem when dealing with the watershed management. Poor moisture availability in addition to various other physico-chemical characteristics and nutrient deficiency, are responsible for poor growth of plants. In order to restore the vegetation cover, productivity in term of fuel, fodder and to regulate the hydrological behaviour of the watershed, micro-interventions using silvipastoral system, i.e. planting of grasses in between trees and shrubs have been carried out in mined degraded areas. The impact of micro-interventions on autogenic progression of other species, soil physico-chemical attributes and infiltration characteristics after seven years of restoration have been studied in Bhitreli micro-watershed of Doon Valley and results discussed in the present paper.
