StartClim2009.A Vegetation Change According to Different Climate and Management Conditions in Austrian Mountain Grassland - A Case Study on Styrian Mountain Grasslands
Abstract
Austrian grassland farming is highly influenced by structural and climatic changes, which may lead to an increase of cutting frequency in favoured regions (with sufficient precipitation and mesic temperature. This project aims to detect whether meadow plants can cope with enhanced stress due to mowing in a changing climatic environment. Therefore field experiments and time series analysis of vegetation shall be obtained on rich grassland concerning mainly diversity (species richness) and biomass production. Considering data on vegetation, site characters and biomass of grassland stands in the Styrian Enns Valley (Tauplitz-Oppenberg) from the years 1997-1999 taken during a MAB-project (Man and Biosphere) repeated measurements in 2008 shall document changes. Thus, 32 meadow sites with management alteration since the last 10 years will be chosen and compared to status quo sites. Cutting regime (2 to 4 times a year) and organic fertilizer (solid/liquid) are the fixed effects on diversity, biomass and growth forms with respect to climatic variables temperature and precipitation. The primary issue of this study is to improve the predictions of vegetation change induced by climate change and changes in management intensity by means of a case study. Additionally, a Dafne project (cooperation BOKU-Institute of Botany, LFZ Raumberg-Gumpenstein and Bio Ernte Steiermark) consisting of a field experiment with same treatment was initiated for next 3 years.
