The grey partridge has declined 92% in the UK since 1967, making it a priority species. Its welfare is intimately linked to arable farming practices that affect chick survival.
Grey partridge chicks die rapidly without sufficient insect food in the first weeks of life — a welfare issue directly caused by pesticide use eliminating arthropod populations from arable fields. Adults in hedgerow-poor landscapes cannot thermoregulate effectively in cold weather. Ground-nesting birds also suffer welfare impacts from mechanical cutting of field margins during the breeding season. Research-based management on demonstration farms shows stark improvements in survival rates when insect-rich margins are maintained.
