IEB Experimental Vegetation Ecology Research Group

Leader of the research group: 
Profile of the group: 

We investigate how changing climate and land use affect vegetation in the sand region of Kiskunsag, Central Hungary. Research topics include the ecological effect of warming, drying, wildfires, and plant invasion, as well as succession following land abandonment and following the removal of alien tree plantations. Approaches range from descriptive local case studies and long-term monitoring, through lanscape and regional-scale surveys, to complex field experiments.
