Project summary


While it may seem small to us the White-Clawed Crayfish is one of the UK’s largest freshwater invertebrates and is an important part of our water systems. This often invisible and largely defenseless species is globally endangered due to non-native competitors joining the pool and widespread habitat loss.

As pressure mounts on crayfish they have started to isolate themselves in small headwaters and in still ponds where they are slightly more protected from the North American Signal crayfish and the crayfish diseases it spreads. However, these small endangered creatures need our help and the South West Peak Landscape Partnership and the Staffordshire Wildlife Trust have a plan.

The South West Peak is an ideal location for the crayfish to recover their numbers. The area has numerous isolated streams and ponds dotting the landscape where crayfish can take refuge and ensure their survival long into the future.

With the leadership of the Staffordshire Wildlife Trust, this project is surveying and monitoring crayfish populations and has identified the best locations for White-Clawed Crayfish to call home. These protected and isolated locations are then populated with crayfish from donor populations so that these endangered invertebrates can recover their numbers in a location free from invasive crayfish and the diseases that they spread.

The Cheshire hills are home to communities of fungal species which are grassland specialists. These communities can be valuable indicators of ancient grassland. Also, like their grassland habitat, they are threatened by improvement, disturbance, or cessation of management.
