We will address our objectives in riparian networks within six river basins in Europe, including Boreal, Continental, Alpine, Temperate and Mediterranean systems. First, we will gather local needs and interests from key stakeholders together with satellite imagery and GIS environmental data for all basins. Then, riparian and river ecosystems functions will be modelled, and ecological hotspots will be identified through a GIS-based multi-criteria, including stakeholders inputs. Then, we will collect in situ data to assess multiple biodiversity and stressors at the local scale and, subsequently, scale-up this information to the network scale using geostatistical tools and advanced modelling. This knowledge will be conveyed to managers at local and EU scales in the form of decisionsupport tools allowing decision makers to identify protection gaps and ecological hotspots along riparian networks based on multiple biodiversity, functional and connectivity criteria.
