Abstract

Present study was carried out in three silver birch (Betula pendula Roth.) stands in the Oxalis site type in South-Estonia. The above-ground biomass, above-ground biomass production and foliar characteristics of 14-, 32- and 45-year-old silver birch natural stands were studied. The above-ground biomass and production of the stand was estimated in August 2008 using dimension analysis (model tree method). The above-ground biomasses in the 14-, 32- and 45-year-old silver birch stands growing on forest land were 39.9; 140.3 and 224.3 t ha-1 respectively. All results are given in dry mass (DM). Current annual production (CAP) of stem mass ranged 4.7-7.5 t ha-1. Leaf area index (LAI) ranged 2.5-4.4 m2 m-2 in the studied stands. Based on these results, stands of silver birch growing in Oxalis site type are very productive and may exceed the respective values presented in yield tables used in Estonian forestry.
