Crayfish

17 November 2021 Off

A key aim of the NRT is to help protect the native crayfish in the Wansbeck and Aln catchments from the invasive Signal Crayfish that are now approaching from all sides.  As part of the work supported by the Environment Agency and a number of other funders we have been undertaking surveys of which species is where, raising awareness of the species through community events, building slippery underwater barriers to slow the spread of Signals and exploring ‘Ark Sites’ where we can hopefully hide away populations of native crayfish.
