Crayfish conservation is accelerating across Wales as organisations work together to protect the white-clawed crayfish, a native species at risk of disappearing from Welsh rivers.

Once thriving across Wales, the white-clawed crayfish is now endangered and faces extinction due to increasing pressures from invasive species like the North American signal crayfish, pollution, climate change and ongoing habitat loss.

To help combat their decline in Wales and boost remaining populations, conservationists are working to establish Ark sites, which are locations where new populations of white-clawed crayfish can safely be established.
