Aboveground biomass in a beech chronosequence in Thüringen (Germany)
A destructive biomass sampling was carried out in a beech chronosequence in Thüringen, Germany, in December 2000 and June 2001. Three plots of different age (40, 70 and 120 years) were investigated, and allometric equations were used to upscale the tree data to the stand. Total aboveground biomass in the 70- and 120-year-old stands is 411.9 Mg ha-1 and 334.3 Mg ha-1, respectively. The 40-year-old stand is mixed, with beech, ash and maples. In this stand, the aerial biomass for beech only is about 62 Mg ha-1. It is likely that, even including ash and maple, stand biomass could hardly attain 100 Mg ha-1, a low value compared to those found in the literature. Actually the younger plot is more heterogeneous than the others and is not strictly even-aged. Partitioning of biomass into stem, branch and leaf is variable. The stems account for nearly 90% of total aerial biomass in the 70-year-old stand, while the 120-year-old stand shows a high percentage of branch biomass. This is partly due to lower stocking of the stand, but other factors also affect biomass.
