The urgent hunt for the rare hairy snail
Scientists and volunteers launch a major effort to save the rare German hairy snail. The species ranks among the most endangered molluscs in the UK, yet new conservation work could revive its numbers. More than 100 volunteers take part in surveys led by Citizen Zoo and the Zoological Society of London. They aim to map the snail’s presence across London and create stronger protection plans. The snail measures only the size of a fingernail, which makes each search difficult. Every confirmed sighting counts as progress for the team.
A charming creature with an ancient story
Joe Pecorelli from the Zoological Society of London calls the species a “charming little creature”. The snail has lived in wetlands and riverbanks for thousands of years. It was first recorded in Britain in 1982. Fossilised remains show it lived here since the Neolithic era. It may even date back to the last Ice Age when Britain remained connected to mainland Europe. Fine fibres on its shell inspired its name. These tiny hairs help it retain moisture and cling to riverside plants and drifting debris that provide food. Habitat loss and pollution cause its decline. Experts believe only a few fragmented sites along the River Thames still support the population.
Protecting green spaces and rare wildlife
Pecorelli says the surveys reveal how the species copes with modern pressures. The work also guides future conservation plans. He stresses that saving the snail helps protect London’s green spaces. These areas must remain healthy for people and wildlife for decades to come. The research team collaborates with the London Wildlife Trust, the Conchological Society of Great Britain and the Port of London Authority. They already found the snail in several places, including Richmond upon Thames, Isleworth Ait and areas near Kew. Elliot Newton from Citizen Zoo felt “over the moon” when he found his first German hairy snail. He describes the creatures as “beautiful and curious-looking”. Newton says the surveys show how cooperation across the city deepens understanding of London’s hidden biodiversity and strengthens community action to protect it.
