Wild Butterfly Conservation: UK Overview 2026

UK butterfly populations have declined by approximately 50% since the 1970s. Targeted conservation through habitat management and monitoring is showing results for some species.

Key Facts

The UK Butterfly Monitoring Scheme is one of the longest-running insect monitoring programmes in the world
Specialist butterflies of rare habitats have declined most severely while generalists are more stable
Climate change is shifting the ranges of some southern species northward
Rewilding projects are creating large-scale habitat mosaics that support butterfly metapopulations
Public participation in butterfly transect surveys provides critical population trend data

Welfare Considerations

Butterfly welfare and conservation are inseparable from habitat quality and connectivity. The aggregate welfare of billions of individual butterflies across the UK is shaped by land management decisions at every scale.

What You Can Do
