The present paper reports on the biomass, forest floor biomass,litterfall and net prinmry productivity in different aged plantations of Pinus patula in Kumaun Himalaya. Biomass increased from 108.9 t ha"1 at a stand age of 15 years to 151.3 t ha'1 at 21 years. The forest floor biomass was 6.9 t ha'1at 15-y-old and 8.9 t ha"1 at 21-y-old plantations. Annual litterfall ranged from 2t ha"1 at 15 years to 3 t ha"' at 21 years. Net primary productivity was 13.5 t ha~'y"'a t age 21 and 12.1 t ha'1y1 at 15 years. The biomass accumulation ratio of these plantations was between 10.3 and 12.7.
