annual biomass production - Opis:
- The paper presents the results of the study on biomass volume and annual production of oak stands in the Niepołomicka Forest. The analysis was based on the material collected from 59 circular sample plots where oak accounted for more than 50% of the volume of the tree layer. In the total biomass of the tree layer amounting to about 225.3 t·ha–1, the biomass of the shrub layer (underbrush) is about 2.3 t·ha–1. In the tree layer biomass (about 223 t·ha–1), wood makes up on average 86.4%, bark – 12% and assimilatory apparatus – 1.6%. The share of wood in the biomass increases with the increase of stand age, while that of bark and assimilatory apparatus declines. The proportion of these elements in the dry mass production (on average 9.8 t·ha–1·year–1) is somewhat different. Almost 35% of its volume is assimilatory apparatus whose share increases with stand age. The increment of bark is about 9%, while of wood it is 56% of the annual biomass production of the stands under analysis and slightly decreases with stand age.
