Conservation headlands are strips of farmland managed with reduced pesticide use around field edges, providing the insect-rich habitat that grey partridge chicks depend on for survival.
Conservation headlands directly address the primary welfare driver of grey partridge chick mortality: starvation due to insufficient insects. In the first two weeks of life, partridge chicks need abundant invertebrate prey — sawfly larvae, aphids, and other small insects — to develop their immune system and growth. Fields treated with broad-spectrum insecticides and herbicides lack these insects entirely. Even a narrow strip of reduced-input farmland at field edges provides sufficient insect prey to sustain chick survival, representing a high-value and cost-effective welfare intervention.
