High Value Freshwater Ecosystems

Mapping opportunities to align ecological restoration & protection of freshwater ecosystems & adjacent areas with climate action

Our Approach

We adapted the High Conservation Value (HCV) framework to define High-Value Freshwater Ecosystems (HVFEs), aiming to support a more strategic and actionable approach for identifying freshwater ecosystems in need of conservation (including both protection and restoration).

HVFEs extend beyond conventional freshwater definitions by integrating freshwater and adjacent terrestrial ecosystems that collectively support the regulation of hydrological and carbon cycles within watersheds.
