Spotted a non-native crayfish?
The Non-Native Species Secretariat have set up RISC, which is The Recording Invasive Species Counts project, which aims to record and better understand the ecology and distribution of invasive species in the UK.
If you have seen a non-native crayfish such as an North American Signal crayfish, you can now record your sighting and help us identify where non-native crayfish are spreading to. You can fill in and send your crayfish sightings here at the NNSS website.
