Abstract
The widespread absence of site maps in Styria requires a new approach to site exploration and mapping of existing forest sites. Another scientific challenge is the consideration of future changed climatic conditions, which will also affect the classification of sites and forest types. For such a required "dynamic site classification" exist theoretical concepts, the concrete implementation of an integrated site and forest classification in a real region such as Styria is new territory.
Within the framework of the project, a forest typing based on a GIS-based geo-ecological stratification model will be carried out. The database will be based on the digital elevation model, a geological base map, digitally available site and climate data as well as new site parameters. For the forest type map, theme maps for the factors heat, water and nutrient balance are to be modeled on the basis of the point and area data, which are then combined into forest types with a uniform combination of factors. The model then allows stratification of the forest types on all main forest sites based on the data basis derived digital geo-ecological parameters (including height, slope, substrate, terrain, slope). Each forest type is displayed on the forest type map at a scale of 1: 25,000. In addition to the ecological facts, each forest type is provided with a silvicultural description containing information on the appropriate tree species, hazards and possible treatment options with regard to climate change. This silvicultural characterization also describes the previous experiences with the existing tree species and their mixtures, separated by forest types, and gives recommendations for future tillering and their management with regard to climate change.
