KEYNOTE A COST-LED EVALUATION OF SURVEY METHODS AND MONITORING FOR WHITE-CLAWED CRAYFISH- LESSONS FROM THE UK
The white-clawed crayfish Austropotamobius pallipes is under threat in the UK and elsewhere in its European range. There is legislation to protect it and a requirement for the status of the species to be monitored. There is a need for a strategy that meets reporting requirements, but allows resources to be targeted to surveys and action that contribute most to the conservation of the species. The paper shows how different objectives lead to differing requirements for information. It takes a cost-led view of survey methods, their benefits and limitations. Using the example of rivers in the UK, it presents an approach to monitoring, in which the priority is the identification of the key threats to white-clawed crayfish. This can inform management decisions about the monitoring to be carried out in future and the options for action in the interests of conservation.
