This project studies:

  • the diversity of higher plants, mosses, lichens and fungi
  • the productivity of grasslands and
  • in experiments the effect of dispersal limitation and disturbance



The major aims of this project are:

1. to assess the effect of land use on the diversity of plants and lichens in grassland and forest as well as on plant pathogenic fungi in grassland,

2. to measure functional and phylogenetic diversity of grassland plants cultivated under standardized conditions,

3. to monitor above- and belowground grassland productivity and nitrogen content as important ecosystem processes, and

4. to manipulate plant diversity experimentally by seeding, disturbance, or plant removal to test the consequences of changed plant diversity for ecosystem processes and how these depend on land use.

The repeated monitoring of diversities and ecosystem processes will further allow us to estimate the stability and resilience of communities, and to relate changes in plant diversity and composition to changes in other taxa. In addition, our project will provide important baseline information for other projects and allow assessing the effect of taxonomic, functional, and phylogenetic plant diversity, and grassland productivity on ecosystem processes and the diversity of other taxa.
