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.

Cumbria Biodiversity Data Centre

The Cumbria Biodiversity Data Centre at Tullie House Museum, Carlisle keeps wildlife information for the county of Cumbria. Tullie House Museum, in its role as a local natural history museum, has collected and disseminated records of wildlife in Cumbria since its inception in 1893. From the early 1990s the Museum has developed a computerised database of species and habitat records in Cumbria and has taken the central role in providing a local biodiversity data service for the county. This role was restyled as Cumbria Biodiversity Data Centre (CBDC) in 2010, a not-for-profit organisation hosted by Tullie House Museum and advised by local stakeholders.

12/12 days of Christmas:
For the twelfth day, we wanted to share the county flower of Cumbria, Grass of Parnassus (Parnassia palustris) or ‘Bog Star’, seen here as wall art in Whitehaven….. Not in flower just yet but look out for it in the summer in damp places across Cumbria.
