On the biodiversity in forest communities rich in/influenced by Pinus cembra: A silvicultural analysis of stands in different altitudes at Mt. Stoderzinken/Dachstein (Styria) : Diplomarbeit, Universität für Bodenkultur, Institut für Waldbau
The main aim of this paper is to investigate the biodiversity of forest communications rich of or influecend by Pinus cembra. The investigation will produce quantitative figures and allow for further analysis to discover whether there are differences concerning biodiversity within and between stands in different altitudes. Finally rules (hints) will be developed on how to treat Pinus cembra forest communities under consideration of protecting respectively increasing biodiversity on the basis of the Shannon/Weaver-Index, the Species-profile-Index by Pretzsch and the Parameters by Füldner. To support these objectives the following hypothesis were proposed and tested: Hypothesis 1: There is a significant difference concerning biodiversity in the herb layer between forest communities poor in tree species near the tree line and forest communities in a lower altitude. Hypothesis ": Forest communities in lower altitudes show a higher diversity respectively differentiation concerning horizontal and vertical structure than forest communities near the tree line.
