A former wheat-growing farm in West Sussex, England, has recorded a remarkable increase in butterfly numbers just two years after a large-scale habitat restoration project began, with 5,290 butterflies belonging to 28 species documented during surveys in 2026. The findings, reported by The Guardian and detailed by Halnaker Hill Farm, include the first recorded sightings at the site of two nationally important butterfly species, offering an encouraging sign of how quickly wildlife can return when farmland is managed for nature.
