Allometric relationship and biomass expansion factors (BEFs) for above- and below-ground biomass prediction and stem volume estimation for ash (Fraxinus excelsior L.) and oak (Quercus robur L.)

Popis výsledku v původním jazyce

Due to changing climate conditions, trends in the proportion of the area of major tree species in Europe will tend to show a greater share of lowland tree species composition. The estimation of tree biomass and its components is needed to determine the amount of carbon held in trees and to plan forest resources. This study presents the biomass functions applicable for ash (Fraxinus excelsior L.) and oak (Quercus robur L.) trees growing in floodplain forest of the Czech Republic, which could subsequently be grouped into more efficient generic model for the particular tree species in the Central Europe. It is based on a detailed destructive analysis of six ash and seven oak trees. The range of the basic predictors of sampled trees included: diameter at breast height (DBH) from 21.3 to 69.7 cm, height (H) from 21.0 to 33.9 m, crown length (CL) from 7.6 to 16.3 m and width of crown (CW) from 3.8 to 14.3 m. The allometric relationships were constructed to derive leaf- (LB), shoot- (BsB), branch- (BB), stem- (SB) and root- (RB) biomass components and to derive aboveground- (TAB), which contains SB and BB, and total biomass (TB) comprising all biomass components. Equations for estimating stem volume were developed, which are required for forest management and it is necessary for planning the availability of commercially valuable wood. Finally, biomass expansion factors (BEFs) converting stem volume into biomass components were constructed. The BEFs were slightly positively linear DBH dependent for BsB, BB, TAB and TB, whereas for LB, SB and RB they were shown to be DBH independent across the diameter distribution of the sampled trees.
