The dataset “Extended wetland ecosystem” is a derived product of the Corine Land Cover (CLS) layer for the year 2018 which has then been reclassified into 20 wetland classes on the basis of ancillary spatial layers (“Water and Wetness 2018” and “Riparian Zone Layer” Copernicus products, the “Ecosystem types of Europe” v3.1 and “The Global Spatial Water Explorer” datasets). Besides the traditional types of inland and coastal wetlands (i.e. marshes, rivers, lakes, lagoons, estuaries), the layer also covers the forest, grassland and agricultural ecosystems which are seasonally or permanently flooded (i.e. riparian forests, wet grasslands, rice fields) and are therefore considered as wetlands according to the Ramsar Convention definition and typology. This wetland reclassification and mapping considers their hydro-ecological characteristics and provides information about the real spatial extent and distribution of varied wetland habitats.

Additional information

A great diversity of wetlands exists making the definition of a wetland ecosystem both challenging and controversial. The development of an extended wetland ecosystem layer according to the definition of the Ramsar convention is an explicit policy request in Europe which builds on an ecosystem-based justification of an inclusive definition, delimitation and delineation of wetlands, looking at the “hydro-ecological” boundaries of this ecosystem (including their wetness and flow characteristics).
