The UK Crayfish website, www.crayfish.org.uk, holds a vast amount of information about native and non-native crayfish populations in the UK. It includes conservation, research, species identification, legislation and much more. The website, launched in 2011 by Buglife and the Environment Agency, now features details of crayfish projects currently being undertaken all over the UK. See here for information about these projects and to submit information about projects not currently listed.
