The Cornish chough returned to Cornwall in 2001 after a 50-year absence, with welfare dependent on short coastal turf grazed by traditional livestock breeds providing invertebrate prey.
Cornish chough welfare is directly linked to the quality of coastal grassland management. Short, grazed turf with abundant soil invertebrate prey supports healthy chick growth and adult condition. Rank, ungrazed vegetation prevents foraging access and causes chick starvation when parents cannot find sufficient prey. The recolonisation of Cornwall demonstrates that targeted habitat management translates directly into welfare improvement for previously lost species. Conservation grazing programmes using native breeds such as the Cornish Chough Reserve cattle maintain the habitat conditions that chough welfare depends upon.
