Wetlands are among the most biodiverse ecosystems on Earth and critical for millions of waterbirds. Their drainage has caused one of the largest wildlife welfare crises in modern history.
Wetland bird welfare is inextricably linked to habitat quality. Wading birds such as curlew are highly mobile and capable of apparent distress responses: curlews are known for their loud alarm calls and distraction displays when nests are threatened. Chick mortality from starvation - caused by invertebrate loss in drained grasslands - is a direct welfare harm occurring on a vast scale across Britain's agricultural landscape. Adult birds that return to depleted nesting sites face nest failure season after season - a chronic welfare stress. Restoration of wet grasslands, re-wetting of drained peatlands, and reduced agricultural drainage are the most important wetland bird welfare interventions.
