Biodiversity declined markedly over the past 150 years with the biodiversity loss in fluvial ecosystems exceeding the global average. River restoration now combines flood safety and biodiversity requirements but the effects are so far locally. At the scale of large river tributaries the recovery remained elusive. Over 179 floodplains, we quantify changes in biodiversity of protected and endangered species over 15 years of river restoration in the embanked floodplains of an entire river delta. We distinguish seven taxonomic groups and four functional groups in more than 2 million field observations of species presence.
Findings and implications to practice
Of all 179 fluvial floodplain sections examined, 137 showed an increase in biodiversity, particularly for fast-spreading species. Birds and mammals showed the largest increase. This shows that flood risk interventions were successfully combined with biodiversity recovery. However, future projects should consider requirements for all endangered species. Explore the storyline for practitioners to get a visual and scrollable overview of the findings.
