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.

Do you have some spare time this summer? CBDC have office based volunteering opportunities available that will allow you to learn new skills and meet new people. We will provide you with the training you need, but you will need to be competent with Microsoft Word and Excel, and have an eye for detail.

Our next recording day will be at Hay Bridge Nature Reserve on the 18th July. CBDC and Rusland Horizons are running an optional workshop alongside the normal recording day for anyone who wishes to learn a bit more about biological recording. In doing so, we hope those of you that are regular recorders can share your skills and expertise with those new to species identification and record keeping. However, you are not obliged to participate in the workshop if you would prefer to spend more time recording. Our online booking form and further information will be available in the next couple of days, but you can also email Debs to book a place. We hope to see you there!

**SIGHTING OF THE WEEK** 17th - 23rd June

The High Brown Fritillary (Argynnis adippe) is the most endangered butterfly in the British Isles. In the UK between 1976 and 2014 its distribution plummeted by 96%, and its abundance by 62%, mainly due to habitat loss. Its European conservation status is “not threatened”, but its current UK distribution is limited to Dartmoor, Exmoor, a small colony in Wales, and on the Morecambe Bay Limestones. This photograph was taken at Arnside Knott by David Cook on the 19th June. To sex this individual the photograph was compared with pinned specimens in the Tullie House Museum Entomological Collections, under the supervision of the museum’s curator Dr. Simon Jackson. This female is typical of Cumbrian records of this species in that it is from the south of the county. Virtually all CBDC records (of which there are 1422) are from the SD 100km square, with just a handful from the southern end of the NY 100km square. In Cumbria, its favoured habitat is a bracken mosaic on limestone outcrops particularly where scrub has been cut back. The caterpillars’s preferred food plants are Common Dog- violet (Viola riviniana), and in particular Hairy Violet (V. hirta) growing on limestone. Bracken areas on upland moorland are too acidic to support violets, so they are unsuitable for High Brown Fritillaries. Conservation methodology is primarily focussed on bracken management providing the right mix of medium and high density bracken patches, thick bracken litter, and open grassy areas which allow the violets to flourish. This is achieved with a mix of cattle grazing, cutting, burning and chemical application.
