Plant regeneration ecology

We study the importance of extreme events such as drought, storms, forest fires or clearings for the forest dynamics. In the frame  of such disturbances we focus on:

  • resistance to disturbance: the potential to resist; we experimentally test the drought resistance of regenerating trees
  •  resilience after disturbance: the potential to regenerate; we monitor severely disturbed forests on the basis of systematic or stratified samples
  • functional traits of forest plant species
     

Both the strong climate warming and a growing demand of forest goods (timber, fuel) will result in a general increase of disturbances. We elaborate basic knowledge for an adaptive forest management.
