Dynamics in mountain forests - natural disturbances and regulative mechanisms
Abstract
The dynamics of mixed-species mountain-forests are determined by site factors, inter- and intra-specific competition and the disturbance regime. The old-growth forest „Rothwald“ and the adjacent stormthrown forest area „Edelwies“ both belong to the wilderness area „Dürrenstein“, a research area of the IUCN-category Ia. This area is unique within Central Europe regarding its size and suitability for basic research on the succession of interacting disturbance factors and regulatory mechanisms. Cooperating with scientists from the FWF-project „Long-term dynamics in Central European old-growth spruce-fir-beech forests: A case study at Rothwald, Austria“, different issues are pursued: a) deduction of the susceptibility of forests to storm-throw and bark-beetle attacks, b) calculation of the risk of bark-beetle infestations (using a model of bark-beetle development and taking into account the role of bark-beetle antagonists), c) deduction of the susceptibility of forests to bark peeling and browsing, d) investigations on the role of small mammals and ruminant game for the forests´ regeneration, e) simulation of biogeochemical cycles in never logged respectively natural forests, initialization of BGC-models, f) reconstruction of the structure of a windthrown forest stand to run different simulations. These project parts are not only important for an understanding of the dynamics of old-growth forest ecosystems, furthermore they are also of interest for managed forests and thus for forest enterprises. Altogether, several different hypotheses and models which are explaining and forecasting the dynamics of old-growth forests and of disturbance events or which are dealing with the function of small mammals within a forest ecosystem as well as the presumed zero-growth in old-growth forests were tested.
