In light of the increasing use of unused forest residues, the knowledge about the amount and sites takes#on special relevance in regard to the planning of bioenergy projects. The volume and its spatial dispersion can be derived from the WEHAM-Data (fig. 1). Therefore, in Baden-Württemberg approximately 1.5 mio. Mg DM/a of forest residues and an additional 0.8 mio Mg DM/a of other wood assortments (e.g. small dimensioned wood) can be supplied for energetic use until 2017 (fig. 2). Considering the amount of forest residues which is used as firewood (0.5 mio. Mg DM/a) as well as an expected mobilisation rate under favourable conditions, the available volume amounts to approximately 1.2 mio. Mg DM/a. However, only half of this amount is easily accessible (tab. 1). Pertaining to the spatial dispersion of these 1.2 mio. Mg DM available volume, the Black Forest displays areas of particularly high volumes (fig. 3). On the other hand, these areas are difficult to access so that it is necessary to analyse the situation in its entirety (cp. fig. 4).
