In the course of this Wienerwald BR project, in Co operation with Forstamt und Landwirtschaftsbetrieb der Stadt Wien (MA 49) and ÖBf AG, the wood is sampled several times
a year over an observation period of 10 years, trapping, collecting and identifying beetles and fungi respectively.
A number of questions were explored in connection with the project: e.g. which properties are linked with which soil types, what are the changes in availability of water to plants, and how good is the nutrient supply in various locations?
The initiation of natural regeneration is one of the most important but also most difficult tasks in the management of semi-natural forests. The extent of benefit from light absorption has a major impact on the regenerative success of beechwoods and oakwoods.
In conjunction with the project entitled ’Integrative, sustainable wildlife management in the Wienerwald BR’, criteria and corresponding indicators were developed for the sustainable management of wildlife and their habitats.
In line with the goals laid down by UNESCO, the core zones of the Wienerwald BR are designated to conserve biological diversity, to monitor ecosystems exposed to anthropogenic disturbance and to implement research projects. Through conservation by non-intervention in natural processes, it is hoped that these areas will become the ‘virgin forests of tomorrow’.
Invasive species such as Tree of Heaven (Ailanthus altissima) and Japanese knotweed (Fallopia japonica ) are on the advance in the Wienerwald. Owing to their dominance and rapid spread, the diversity of plant species and thus the resilience of native ecosystems is reduced.
