Glutinous snails, aquatic creatures no larger than a fingertip, have become critically endangered in the United Kingdom. Once distributed across numerous waterways throughout the country, the species now exists in a single natural location: Llyn Tegid, a lake situated within Eryri National Park in Wales. Scientists attribute the dramatic population decline to habitat destruction and shifts in environmental conditions that have made survival increasingly difficult for the species.
Wingham Wildlife Park, located near Canterbury in Kent, has joined a coordinated national initiative to prevent the species from disappearing entirely. The facility obtained a small number of snails from the wild population to establish a captive breeding program. According to Samantha Eden, an assistant curator at the park, the initial breeding cohort consisted of six adult snails. The program has already achieved significant success, with staff recently relocating approximately 130 juvenile snails from one pond to establish a separate breeding colony at the facility.
The transportation of snails to the park during the start of July yielded an unexpected benefit. Staff members transporting 24 snails in a six-hour journey from Wales discovered that the creatures had begun reproducing during the drive itself, producing roughly 12 egg pods by the time the journey concluded. Hannah Ellins, who oversees the reptiles and invertebrates department, noted that while the park typically focuses on exotic species, the opportunity to contribute to the conservation of native British wildlife represents a meaningful addition to their work.
The breeding initiative at Wingham Wildlife Park represents one component of a broader conservation network. Multiple facilities have committed to the effort, including Askham Bryan Wildlife Park in York, Longleat in Wiltshire, Dudley Zoo, and Chester Zoo. The Freshwater Habitats Trust is collaborating with these institutions to identify appropriate water bodies suitable for eventual release of captive-bred snails into the wild, with the goal of restoring the species to its historical range.
