B-Lines

Saving bees and other pollinators from extinction by restoring rich, wildflower habitats across the UK.

Throughout the UK, 97% of species-rich grassland has been lost since 1940, mainly due to modern farming methods and urban spread. As a result, 75% of our pollinators are in decline, and 35 species of bees face extinction.

Much of our wildlife is now confined to tiny, isolated habitats and, if action isn’t taken to restore and reconnect them, between 40 and 70% of native species may go extinct.

The B-Lines initiative intends to help combat this catastrophic bio-diversity loss via the creation of a UK-wide network of pollinator-friendly habitats, known as ‘B-Lines.’ This network of B-Lines will restore at least 150,000 hectares of rich meadows and grassland, and reconnect currently isolated habitat areas all over the UK.

Before launching the B-Lines project, Buglife and Natural England asked CBDC to map out existing insect pollinator populations across Cumbria, Lanashire, and Greater Manchester.

In collaboration with other record centers, we analysed, edited, and digitally mapped out existing and collected pollinator habitat data, via ArcGIS model building. Our maps formed the working foundations for the North West B-Line networks, and helped to develop project methodology that was used in other B-Line projects around the UK.

Thanks to our work in the North and contribution to the wider B-Lines project, CBDC was hired to work on the Bee Roads South project.

Stage 1 began with a collaborative effort from local recording and data centers to identify potential habitats. During Stage 2, we evaluated the quality and suitability of these habitats, narrowing them down into Core Areas. A 3 kilometre buffer was added around the Core Areas, which provided the first step towards creating the B-Line network. During Stage 3, we used digital modelling to analyse terrain and map out the most efficient way to connect the Core areas, founding the B-Lines network.

Young mudshrimps Corophium are growing & moulting right now; a friend once described the piles of cast exoskeletons as 'like snow-drifts' along the shore. Not quite such dramatic nos. here but I was thrilled to find them - the long antennae are clearly seen https://t.co/Fmtf33Duf9 CumbriaBDC photo
