Two enclosures of 0.5 hectares each, one on flat land and the other on 50 degree slope, western exposure, were established in alpine grazing lands at Paya (Kaghan) during 1969 and 1971 respectively. The effect of closure was studied during September, 1976, seven and five years respectively after their establishment. Due to closure the forage production increased about three fold. The increase was due both to increase in grass and forbs. No appreciable difference was found in the frequency of grasses or forbs of desirable, intermediate or undesirable species due to closure.
