New research has revealed that butterfly populations in the UK are thriving in areas with abundant trees and hedgerows, highlighting the crucial role of natural field boundaries in supporting biodiversity.

The study, conducted by conservation scientists and published this week, found that woodland edges and well-managed hedgerows create ideal microclimates for butterflies by offering shade, shelter from wind, and access to nectar-rich plants. Species such as the Speckled Wood, Gatekeeper, and Brimstone were notably more abundant in areas with diverse tree cover and hedge structures.

“These linear habitats act as wildlife corridors,” explained Dr. Emily Hargreaves, lead researcher. “They help butterflies move across landscapes and connect fragmented habitats — a key factor in building climate resilience.”

The findings come amid increasing calls to expand nature-based solutions across British farmlands and rural developments. Conservation groups are urging landowners and councils to restore and protect native hedgerows, not only for aesthetic or historical value but as a critical step in combating pollinator decline.

With more than 75% of the UK’s butterflies showing long-term declines, environmentalists stress that simple actions — like planting trees and letting hedges grow wild — can make a powerful impact.
