Irish butterfly populations showing a decline

The Irish Butterfly Monitoring Scheme, organised by Tomás Murray at the Waterford-based National Biodiversity Data Centre, began in 2008 so the details of the scheme are now well established. The overall trend in Irish butterfly populations since 2008 shows a decline of 6%. The recently-published Newsletter No 11 reveals that last year, 110 volunteers walked 115 transects and recorded more than 46,000 butterflies. The Small Heath (Coenonympha pamphilus) experienced the strongest decline.
