Welcome to the Yorkshire Branch of Butterfly Conservation

Butterflies are not only beautiful and fascinating creatures but are also highly responsive to the environment. David Attenborough described them as 'A thermometer of the health of our natural world' Almost every species of butterfly is in decline and a quarter are facing extinction. We have lost more than 97% of our traditional meadows and woodland in recent times so it is crucial we raise awareness about the threats facing our butterflies, moths, their habitats and our natural environment. Yorkshire Branch work in partnership with land owners, local authorities, conservation bodies, businesses and the local community to achieve this.

Here in Yorkshire the Duke of Burgundy and Pearl Bordered Fritillary are particularly vulnerable due to habitat loss and increasingly susceptible to extinction. Yorkshire also has the only remaining colony of the Dark Bordered Beauty Moth in England, on Strensall Common and is on the brink of extinction.

Become a member today and help us save butterflies, moths and their habitats. There are many rewarding roles volunteering in recording and conservation; you will be surprised to find out what is on your doorstep! We have a real challenge when 60% of children in the UK have never seen a Peacock butterfly according to a YouGov Survey and 78% of parents are concerned that children don’t spend enough time interacting with nature. Founded in 1981 Yorkshire branch wil be 40 years old next year and has more than 1800 members.

An 'Introduction to the Yorkshire Branch of Butterfly Conservation' online event held on 25th Febuary

Our first online event was rather special and proved to be very popular and well recieved. Held to allow our members to meet those closely involved with helping conserve Yorkshire's species and key people within our branch, including committee members, recorders, and BC regional staff and hear what they are involved in. BC Yorkshire wants to ensure we are doing the best possible job for our members, as well as our butterflies.

You can watch all our past events recordings on YouTube HERE

February 23rd Patrick Barkham writing in the Guardian highlights the row over UK tree-planting drive: 'We want the right trees in the right place' as multple agencies critisise the rush the Forestry commision are in to get trees in the ground to match government ambitious targets. But it cannot be at a substantial cost to biodiversity as Patrick outlines many examples including Butterfly Conservation's objection to tree planting in Wareham Forest where Grayling still strive and would be lost by tree planting.

Science Spotlight : Are Grizzled Skippers stuck in the south?

Population‐level responses of an early‐successional specialist butterfly to climate across its UK range over 40 years

Climate change has been predicted to facilitate poleward (northern) expansion of many early‐successional specialist invertebrates. The Grizzled Skipper, Pyrgus malvae, is a threatened butterfly in long‐term decline that has not met expectations of northern expansion in Britain, possibly indicating that climate change has not improved northern habitat suitability or that another driver (e.g. land use change) is masking its effects. The article explores the effect of climate on population size trends over four decades, and whether any regions show an improving population trend that may be a precursor to northern expansion.

We found that P. malvae population size declined more over time in the north and west of its UK range than in the south and east, and was negatively related to high December temperature and summer rainfall. However, the effect sizes of temperature and rainfall were minimal
