UK's Last Glutinous Snails Saved in National Conservation Effort
Zoos and conservationists unite to rescue a rare mollusc species from extinction.
1The Rarity of the Glutinous Snail
The glutinous snail (Myxas glutinosa), once widespread across the UK, is now found only in Llyn Tegid, Wales' largest natural lake. This tiny mollusc, no larger than a fingertip, is known for its delicate, gold-flecked shell and a gooey mantle that gives it its name. Conservationists compare its ecological value to that of an Egyptian artefact, highlighting its role as an indicator of healthy aquatic ecosystems. Pollution and habitat loss have driven it to near extinction in England, making its preservation critical.
2A Backyard Conservationist's Mission
Ian Hughes, a dedicated conservationist, has made it his life's work to save the glutinous snail. Starting in 2014, he began collecting and studying these snails under a license from Natural Resources Wales. Hughes even designed concrete shelters in Llyn Tegid to protect them. His home in Llanarth became a sanctuary, with over 2,000 snails bred in homemade tanks. His breakthrough came when he successfully observed their eggs for the first time, a milestone in understanding their reproduction.
3Family Involvement in Snail Rescue
The Hughes family, including Ian's wife Kerry and their three sons, has fully embraced the mission. They brave freezing lake waters in January to collect snails, driven by the belief that every species plays a vital role in the ecosystem. Ben Hughes, 27, describes the effort as rewarding despite the challenges. The family also rears other critically endangered invertebrates, such as scarlet malachite beetles and ladybird spiders, turning their home into a hub for conservation.
4Zoos Join the Rescue Effort
The British and Irish Association of Zoos and Aquariums (BIAZA) has partnered with the Hughes family to relocate snails to wildlife parks across England. Wingham Wildlife Park in Kent, Askham Bryan Wildlife Park in York, and Longleat in Wiltshire are among the participants. These zoos have created specialized habitats, including ponds, to breed and study the snails. The goal is to eventually reintroduce them to the wild, supported by a £60m UK government scheme for rare species protection.
5Scientific Research and Future Plans
Nicky Needham, head of species management at BIAZA, emphasizes the importance of research into the snails' ecology, husbandry, and genetics. This data will guide reintroduction efforts, with hopes to achieve wild releases within three years. The Freshwater Habitats Trust is identifying suitable water bodies for future releases. Climate change poses an additional threat, making the zoos' role in maintaining captive populations even more crucial for the species' survival.
6Community and National Pride
Eryri National Park, home to Llyn Tegid, takes pride in hosting the UK's last glutinous snails. Assistant warden Simon Jones calls the project 'amazing' and pledges full support. The park recognizes the snails' uniqueness and the heightened risks they face due to environmental changes. Local and national efforts are now aligned to ensure these snails are not just a memory for future generations but a living part of the ecosystem.
7Challenges and Innovations
Conservationists face significant challenges, including the snails' extreme delicacy and specific habitat needs. Hughes' concrete shelters and captive breeding programs are innovative solutions to these problems. The collaboration between zoos, researchers, and volunteers exemplifies a multifaceted approach to conservation. Each small success, like the first observed eggs, is a step toward reversing the snail's decline.
8A Legacy for Future Generations
For Ian Hughes, preserving the glutinous snail is a duty to future generations. He likens the snails to treasures, as valuable as historical artefacts. The project's momentum, fueled by national support and scientific collaboration, offers hope. By diversifying conservation efforts across multiple sites, the UK aims to avoid the peril of 'having all eggs in one basket,' ensuring the species' long-term survival and ecological contribution.
