EMPIRICAL FORMULAE TO ASSESS THE BIOMASS OF THE ABOVE-GROUND PART OF PINE TREES

Jarosław Socha, Piotr Wężyk

 

ABSTRACT



The material for the studies were the results of the measurements carried out on 113 experimental trees coming from the experimental plots located in the monitoring network established in the Niepołomice Forest (Puszcza Niepołomicka) within the project FOREMMS 5PR UE [20]. After cutting down the trees wet biomass of twigs with needles was determined. Stem discs were also taken to make stem analysis. In laboratory conditions dry mass of twigs with and without needles was determined. The dry mass of stem and twigs was determined based on wood density in pine. Using the correlation analysis the features explaining most variability of respective components of the above-ground biomass of trees were selected. These features were used to assess empirical formulae to measure biomass. The formulae to assess biomass of stem, twigs, needles, cones were made as well as the formula to measure the whole biomass of the above-ground part. At the present stage the proposed empirical formulae can be applied

Key words: needles biomass, twigs biomass, stem biomass, allometric formulae, Scotch pine..
