Comparative biodiversity analysis of natural reserves and managed forest areas
Abstract
In the wake of UNCED Conference in 1992 the concept of sustainability became a public interest. With follow-up results like the Pan-European Criteria and Indi-cators for SFM (1998- 2003) or Johannesburg 2002 biodiversity issues involved high demands and efforts to forestry in Europe and all over the world. In this context forest biodiversity was reviewed and analysed with respect to current requirements from the environmental policies. It showed out that human influences and impacts on forest ecosystems working directly and indirectly are of major concern regarding biodiversity. Examples of measures that have been taken to mitigate these effects include the installation of a network of nature forest reserves (e.g. Austrian Federal Office and Research Centre for Forests – BFW, Madhupur National Park, Sundarbans Bangladesh). These networks of nature forest reserves aims at, inter alia, investigating natural ecological processes and de-veloping respective methods of close-to-nature silviculture. So this study will focus on comparative analyses of biodiversity in mixed, uneven-aged coniferous forests of natural reserves and managed forest areas. Permanent sample plots in different natural reserves in Austria and Bangladesh will be used to analyse structure and composition of forest elements (e.g. natural regeneration, tree characteristics, vegetation patters, coarse woody debris, higher taxon richness (using genera or families) as a surrogate for species richness) as indicators for forest biodiversity. The biodiversity of these natural reserves will be compared with managed forest areas of similar site and topography which had been continuously managed for more than 200 years. The data will be analysed by detrended correspon-dence analysis (DCA), to evaluate the relative influence of the environmental variables on the vegetation composition and degree of heterogeneity, and to look for species characteristic of untouched forests with regard to biodiversity issues. The results of the study will help to identify the effects of forest management on the different levels of biodiversity of forest communities. Therefore the studies will help to increase our knowledge about a sustainable management of forest ecosystems with respect to biodiversity aspects.
