Site locations

The interactive map below shows all the locations across the UK where we have BMS transects. Results from these feed into all our analyses. Click on the markers to drill down through countries and counties. Click on the map's Back button to go back up a level. Use the zoom and pan controls to see more detail.

Alternatively, you can find out more by viewing a list of all locations.

The UKBMS is run by  Butterfly Conservation (BC), the Centre for Ecology and Hydrology (CEH) and the British Trust for Ornithology (BTO), in partnership with the Joint Nature Conservation Committee (JNCC), and supported and steered by Forestry Commission (FC),  Natural England (NE), Natural Resources Wales (NRW), Northern Ireland Environment Agency (NIEA), and Scottish Natural Heritage (SNH). The UKBMS is indebted to all volunteers who contribute data to the scheme.
