Intermittently flooded areas, called temporary wetlands dry out seasonally, sometimes for several years but often every year or sometimes unpredictably. They are sensitive to global change, especially in the boreal areas. They are hotspots of biodiversity, hosting specific flora and fauna adapted to the hydro-periodicity. They are typically devoid of fish, thus allowing the development of amphibians, invertebrates and flora that are sensitive to fish predation and destruction. Their particular biochemical functions have been largely impacted by drainage that often targeted shallow and temporary wetlands. However, the restoration of temporary wetlands appears to be an effective tool to return their ecosystem functions for sustainable forest managements. However, a lack of rigor and coherence in the regulatory protection of small aquatic resources remain a global phenomenon. The POOL project gathers the expertise of a multidisciplinary team of researchers, artists and stakeholders to raise awareness on temporary wetlands in European boreal forests. POOL will propose nature based solutions using temporary wetlands for a sustainable management of forest with wetland conservation.
