Wild Meadow Brown Butterfly: Grassland Management for Welfare

Meadow brown butterfly populations depend on traditional unimproved grassland management that provides larval food plants.

Key Facts

Meadow brown larvae feed on grasses including fescues, bents, and meadow grasses
Unimproved grassland with structural diversity supports higher butterfly abundance
Rotational cutting leaving areas uncut each year maintains suitable sward structure
UK butterfly populations declined by 46% between 1976 and 2017 on monitored sites

Welfare Considerations

Butterfly larvae starving or unable to pupulate due to habitat destruction experience welfare costs that scale with their number. Grassland management that maintains diverse sward structure directly reduces these welfare costs by maintaining food plant availability.

What You Can Do

Manage any grassland areas rotationally, leaving some uncut each year
Plant native grass species that support butterfly larvae in garden meadow areas
Participate in Butterfly Conservation UK monitoring and advocacy
