Geometrische Kennzahlen für die forstfachliche Bewertung der Zersplitterung von Privatwaldarealen

Due to the importance of forests for our society, a sustainable and efficient cultivation is in the general interest. About half of the forests in Bavaria is private property; in particular in private forest areas, the lots of owners often are of bad shape and lie scattered over the region, which is detrimental to a future-oriented cultivation. It is intuitively possible to describe the problem factors in a qualitative way, but in forestry consulting and for the owners themselves quantitative measures are of special interest. We present and discuss a couple of such quantitative measures. Their central significance for the evaluation of the scattering of forest areas was identified in workshops by experienced forest professionals. The measures are based on the lot geometries of the properties, which are available since there is geodata for forest regions. We classify them in three categories as regards content. Additionally, we discuss some details of the underlying data basis. The computation, indication and visualization of the presented measures were implemented in an intuitive software-tool "ArborTec", for which no GIS-knowledge is necessary. This yields a foundation for an application of our results in practice. We conclude our discussion with some recommendations of an application of the measures in forestry consulting.
