Crayfish in Britain: Native and Invasive Non-Natives
6 September 2012
Rye Meads RSPB Reserve, Hertfordshire
Tutor: Paul Bradley MIEEM
Level: Beginner - Intermediate
(NB This workshop was originally due to take place on 27 March 2012, but has been rescheduled for 6 September).
Invasive non-native crayfish, of several species, are becoming an increasing dominant component of freshwater systems throughout southern Britain.
This new workshop will provide a unique opportunity to see most of the crayfish species that now occur in the wild in Britain.
With special permission from the Environment Agency, we aim to show participants live American Signal Crayfish, Narrow-clawed (Turkish) Crayfish, Red Swamp Crayfish, Virile Crayfish, and native White-clawed Crayfish. We will also provide an introduction to all other non-native species that have been recorded, or might be illegally introduced to Britain. The invasion ecology of each species will be described.
With the economic and ecological impacts of invasive crayfish in Britain becoming increasingly apparent, the workshop will provide an introduction to dealing with invasive species and conserving the region’s natives.
