Short summary

Non-floodplain wetlands (NFWs) – wetlands located outside floodplains – confer watershed-scale resilience to hydrological, biogeochemical, and biotic disturbances. Although they are frequently unmapped, we identified ~ 33 million NFWs covering > 16 × 10 km² across the globe. NFWs constitute the majority of the world's wetlands (53 %). Despite their small size (median 0.039 km²), these imperiled systems have an outsized impact on watershed functions and sustainability and require protection.
