Abstract
A plant community of Pinus nigra Arn. with a 70-80 years old stand was investigated. The aboveground phytomass of the stand was 278 t/ha. Th e stem biomass was increased with 23,6 t/ha every 5 years (dry weight) . The litter fall per year was 3,5 t/ha. The mean value of the ground layers production was reached to 897 kg/ha/y. The whole aboveground ph ytomass in the community was 282,3 t/ha.
