The conservation status of freshwater species and habitats in Key Biodiversity Areas at the Douro river basin
2022
This report presents the results of a broad assessment of freshwater diversity in the Douro river basin in Spain and Portugal. The Douro river basin is the largest of the Iberian Peninsula, and an ecological region of great value due to the high diversity of ecosystems and the number of species. A total of 14 sites, either identified as Key Biodiversity Areas (KBAs) or potential KBA sites, were surveyed for fish and macroinvertebrate species.
