NWR OF FORESTS AND CLIMATE CHANGE ADAPTATION
Ivan Pilaš, Croatian Forest Research Institute Sava river (Croatia) – using natural floodplains as NWR for flood protection
• The largest complex of alluvial floodplain wetlands in the Danube basin and the largest lowland forests
• The Sava is a unique example of river where the floodlplains are still intact, supporting both floods alleviation and biodiversity (NATURA 2000 areas)
NWR in support of flood protection Žutica forest retention area – 6400 ha
NWR to NWR in support of biological conservation DANUBEPARKS is a network of protected areas along the Danube River that constitute unique natural areas of ecological, scientific and cultural importance on an international scale.

The main objective of AFORENSA is to generate relevant knowledge how the forest ecosystems in Croatia responds to observed extreme climatic variations, and what are possible future expectations in respect to the progression of climate change and disturbances of natural hydrologic cycle with intensification of drought frequency and severity. Forest vegetation and NWR
Alpine
Continental
Mediterranean
Mediterranean trees show higher NWR potential and better water conservation, they are not limited to growing season! Inherent WR of forests as resilience strategy
Thank you!
