Intercantonal Permanent Forest Observation Programme

Since 1984 the IAP conducts research in the fields of forest ecology and plant physiology. Our main concern is the health of forests in Switzerland and urban trees in Basel, which we monitor in permanent plots. In addition, we conduct case studies and field experiments to address specific questions. We run the Intercantonal Permanent Forest Observation Programme on behalf of Swiss cantons (AG, BL, BS, GR, LU, OW, NW, SO, SZ, TG, UR and ZH). Data analysis and special examinations are funded by the Swiss Federal Office for the Environment (FOEN).
