Level II

Intensive monitoring is the key for providing insight into causes affecting the condition of forest ecosystems and into effects of different stress factors.

Set up of the ICP Forests intensive monitoring

  • Around 800 plots have been established
  • Major forest types of Europe are represented
  • The integrating evaluation of different surveys offers the possibility to understand complex ecosystem processes
