Conservationists Unite to Save London’s Rare ‘german’ Hairy Snail

The Race to Save London’s Rare Hairy Snail

In a bid to preserve one of Britain’s most unique and endangered species, conservationists and citizen scientists have joined forces in an effort to save the German hairy snail (Pseudotrichia rubiginosa) from extinction. This charming little creature, with its distinctive slim shell covered in fine hairs, has called London’s riverbanks home for thousands of years but is now facing severe challenges.

A Species Under Threat

First recorded in the UK in 1982, this rare snail species was believed to have originated from continental Europe and thrived during the ice age. However, due to habitat loss and other environmental pressures, the German hairy snail has become one of the UK’s most endangered molluscs. The snails are currently found only in small, fragmented patches of their historic damp riverside habitat along the River Thames.

Conservation Efforts

The project is led by Citizen Zoo and the Zoological Society of London (ZSL) with support from various partners including the London Wildlife Trust. Over the past few months, teams have been conducting surveys in boroughs such as Newham, Richmond upon Thames, and Barnet to better understand the snail’s distribution across the capital.

Joe Pecorelli, freshwater conservation programme manager at ZSL, emphasized the importance of these surveys: “This charming little snail has called our riverbanks and wetlands home for thousands of years—yet it is sadly now very rare in the UK, potentially restricted to just a few sites along the Thames.” The team hopes that by mapping the snail’s current range, they can identify areas critical for conservation and develop strategies to protect these habitats from further degradation.

Adapting to Modern Challenges

The German hairy snail has developed unique features to adapt to its environment. Its fine hairs on the shell allow it to sweat off moisture, making its slime sticky enough to cling onto slippery riverside debris and plants where it feeds. This adaptation is crucial for survival in London’s often wet conditions.

Elliot Newton from Citizen Zoo added: “The German hairy snail is a species that helps spark imagination and open people’s minds to the curious and diverse wildlife that can thrive across Greater London.” He highlighted how collaboration with local communities could lead to a deeper understanding of London’s hidden biodiversity, ultimately helping both the snail and other species.

The project involves working closely with organizations such as the Conchological Society of Great Britain and Ireland, Greenspace Information for Greater London CIC, and the Port of London Authority. Funding support comes from Thames21 and the Conchological Society itself.

Looking to the Future

By identifying how habitat restoration, pollution management, and careful relocation can help recover snail populations, conservationists hope to secure a future for these fascinating creatures in their historic home. The team believes that such efforts will not only protect the German hairy snail but also safeguard green spaces across London, benefiting both people and wildlife.

The work of these dedicated conservationists serves as a reminder of the importance of preserving biodiversity in our cities, where nature can often be found just beyond the familiar urban landscapes. As they continue their vital research, there is hope that one day, the German hairy snail will once again flourish along London’s riversides.
