SECURING A FUTURE FOR NORFOLK'S WHITECLAWED CRAYFISH
White-clawed Cray昀椀sh (WCC) are an endangered
species threatened by invasive non-na}ve
species, disease, and loss of habitat. We aim to
improve our knowledge of the remaining range
of the WCC in Norfolk through e-DNA sampling
and surveys. This informa}on will be used to
iden}fy suitable sites to carry out habitat
enhancements including the addi}on of woody
material and cobbles suitable for WCC refuge.

of a Cray昀椀sh Hatchery at Banham Zoo by
providing training and match-funding.
Outputs:
