Description: Das Projekt "ForestBIOTA - Strukturdiversität" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Arbeitsbereich für Weltforstwirtschaft und Institut für Weltforstwirtschaft des Friedrich-Löffler-Institut, Bundesforschungsinstitut für Tiergesundheit durchgeführt. Objectives: Biodiversity has gained global attention particularly since the UNCED conference in Rio de Janeiro in 1992. In April 2003, the forestry ministers of Europe and the European Community declared the aim to 'further maintain, conserve, restore and, as appropriate, enhance forest biological diversity'. In December 2003 the forest Focus regulation of the EU entered into force aiming inter alia at the development of forest biodiversity monitoring in Europe. In this context, the ForestBIOTA project was created in order to further develop monitoring methods for some aspects of forest biodiversity and to carry out correlative studies between some compositional, structural and functional indices of forest biodiversity. The project is based on more than 100 already existing intensive monitoring plots of the EU and ICP Forests monitoring programme with well established infrastructure and data base and is coordinated at the Institute for World Forestry. Until today, harmonized methods for the assessment of (i) stand structure (ii) deadwood (iii) epiphytic lichens (iv) ground vegetation and (v) forest classification have been developed. Results: A detailed assessment of forest biodiversity aspects needs to take into account the differing composition, structure and functioning of forest ecosystems across Europe. A classification into 28 forest types was therefore successfully tested. Results show significant relations of all the newly assessed parameters to the forest type of the respective plots. Forest stand structure characterised by diameter variation and deadwood occurrence differed between forest types. The same was true for ground vegetation characteristics and for the number of epiphytic lichen species per plot. A harmonized method for deadwood assessment proved to be feasible. The occurrence of deadwood was significantly related to the age of the stands. Forest management was an important factor affecting the amount of deadwood in European forests. In total, 276 epiphytic lichen species were recorded on sample trees of 83 test-plots. In many countries the assessments include valuable records of threatened and endangered species. Plots with a lower number of epiphytic lichen species had significantly higher sulphur and nitrogen deposition. There are clear indications that both sulphur and nitrogen deposition affect lichen species number and as well lichen species composition.
