Salix riparian communities are particularly diverse and of extraordinary ecological importance. This study will analyze the diversity of Salix riparian communities (S. alba, S. fragilis, S. purpurea and S. triandra), their distribution, ecological importance, and conservation. There were 444 records for S. alba, 417 for S. fragilis, 457 for S. purpurea, and 375 for S. triandra, both from the literature and herbaria. Thus, it can be seen that the distribution of the four Salix species studied is very widespread throughout the territory where this study was carried out. According to EIVE (Ecological Indicator Values of Europe) but also to the national list values for niche positions and niche widths, they were noted to be very close for all ecological indicators: M (soil moisture), L (light), and T (temperature), but not for the ecological indicator of soil nitrogen (N) availability or R (soil reaction). Obviously, those riparian Salix communities are important for the functions they indicate, primarily for climate change mitigation, but also for regulating water flow, improving water quality, and providing habitats for wildlife. Conservation and management of these important ecosystems are necessary to maintain their biodiversity, and ecological services and strategies that can be used to protect and manage these communities are outlined.
