Abstract:
The protected forest “Brentenkogel“ has to protect people, settlements, power supply systems and roads from natural hazards. First notations from this area were made in 1982. 17 years later, in 1999, another inventory sampling was conducted. Due to the expansion of the protected forest area to 110 ha, the sampling network has been extended as well to 110 ha. This expansion was realized in course of a pilot project In 2009, in course of this project, an evaluation matrix for 26 areas in the protected forest was developed. These areas were presented as thematic maps in ArcGIS. The aim of this thesis is on the one hand a comparison of the forest’s development from 1982 to 2017, and on the other hand a comparison of the measure areas’ development from 2009 to 2017. The evaluation of the notations is both, on the inventory sampling and the measure areas, unsatisfactory. Due to the high browsing rate, caused by rockfall and a high canopy closure, the development of rejuvenation is poor. Older areas which are protected by fences, show a good development. In future, these areas will ensure an adequate protection against natural hazards. Only the protective effect in the middle and the lower part of the protected forest area, due to a lack of rejuvenation phases and thicket phases, is limited. Based on the results of the inventory sampling, the development of the forest in 50 years’ time was simulated with the program Prognaus Vers. Px 1.1 (LEDERMANN, 2007). Five different kinds of treatments were simulated by Prognaus. Most of the technical buildings are in good conditions, however decay can be anticipated in the next 30 years. In order to preserve the forest’s protective function, silvicultural measures must be taken immediately.
