A study of Northern Brown Argus in the Scottish Borders by wildlife charity Butterfly Conservation Scotland (BCS) has revealed the region to hold significant nationally important colonies. However, sadly 54 out of 92 butterfly colonies identified have been deemed as under long-term threat primarily from unsuitable grazing and afforestation.
The Northern Brown Argus is a small chocolate brown butterfly that has its UK stronghold in the Scottish Borders region. The butterfly is high priority species for BCS as its favoured habitat, species-rich grassland, is in severe decline.
In recent summers a team of BCS volunteers have been surveying many of the Northern Brown Argus colonies in the Scottish Borders and have found that almost half are at risk of being lost. MORE
