Meadow brown butterflies depend on unimproved grassland - their decline mirrors the loss of species-rich grassland across the UK.
Meadow brown welfare is fundamentally linked to the availability of unimproved grassland with diverse plant communities. The UK has lost over 97% of its species-rich grassland since 1930 - the most profound habitat loss of any UK habitat type. Every remaining grassland fragment and each newly created grassland contributes directly to meadow brown and other grassland insect welfare.
