Thousands of rare snails released in Pentland Hills as part of conservation efforts

Thousands of rare pond mud snails have been released into wetlands around the Pentland Hills as part of a conservation project run by the Royal Zoological Society of Scotland (RZSS). 

Alongside local MP Scott Arthur, and species steering group members from the RSPB, and the Pentland Hills Regional Park Service, the wildlife conservation charity released over 3,000 snails into ponds and marshes near the Threipmuir Reservoir and Bavelaw Marsh area.  

Dr Helen Taylor, deputy head of conservation at RZSS, said: “Once widespread, this vulnerable species is now found at only a few sites in Britain. RZSS has been successfully breeding these snails since 2017 and has learned a lot about the species during that time.  

“As a wildlife conservation charity, we’re always determined to stand up for the little guy and the success of our breeding programme has meant that we can now release thousands of snails into specially selected sites, giving the wild population a significant boost. 

“But this isn’t the end. Regular monitoring is required to check the species is not only surviving but thriving. It’s brilliant to be able to do this kind of work right on our doorstep, just outside Edinburgh – proof that conservation doesn’t have to be restricted to remote locations.” 

Pond mud snails play an important role in the ecosystem, acting as natural cleaners by consuming dead plants and organic waste. They also help control excessive algal growth and recycle nutrients back into the water. By protecting pond mud snails, RZSS is helping maintain healthy ecosystems that benefit other wildlife and people alike. 

The pond mud snails project is only possible thanks to support from the Scottish Government’s Nature Restoration Fund.
