The Guardian web site:- “The conservation charity Buglife hopes to help restore and create at least 150,000 hectares of wildflower pathways with the launch on Monday 13th July 20 of its B-lines network for England.
B-Lines are a strategically mapped network of existing and potential wildflower habitats that criss-cross the country. The 3km-wide corridors stretch from the coast to the countryside and towns and cities, covering in total some 48,000 sq km of England….”
In Monmouthshire, B-Lines run from Chepstow up the Wye Valley and also Chepstow, Usk, Abergavenny and Monmouth.
