Part II - Sustainable Biomass Resources

Summary

Abstract

Forests are important for providing wood for products and energy, and the demand for wood is expected to increase over the next decades. The potential woody biomass supply was estimated for the period 2000–2020 for stem wood as well as residues, taking into account economic, environmental and technical restrictions. Constraints reducing the availability of forest biomass were defined and quantified for three mobilisation scenarios and five wood price scenarios in order to estimate the realisable potentials. The theoretical biomass potential was estimated from Austrian forest inventory data and applying the PROGNAUS forest growth simulator. It lies between 32.7 and 38.4 million m3 equivalents yr-1 over bark for the period 2000–2020. The realisable potential in Austria was estimated in a range between 23.9 and 31.1 million m3 equivalents yr-1 over bark for the period 2000–2020. These potentials represent 73–84% of the theoretical potential. Nutrient sustainability in the context of whole-tree harvesting appeared to be an important constraint when considering how much biomass is realisable from forests. The attitude of private forest owners towards increased harvest of forest biomass is also of major importance for the realisable potential, given the small-scale structure of forest ownership in Austria.
