Meadow browns are common grassland butterflies that have declined with loss of unimproved meadows, with welfare implications for populations in fragmented habitats.
Meadow brown welfare under precautionary insect welfare approaches depends on grass-rich unimproved meadows. Grassland intensification removes the larval food plants and adult nectar sources they require. Maintaining and creating unimproved grassland supports both population viability and individual butterfly welfare across the life cycle.
