A HISTORICAL GAZETTEER

OF THE WHITE-CLAWED CRAYFISH

(AUSTROPOTAMOBIUS PALLIPES Lereboullet, 1858)

IN WATSONIAN YORKSHIRE

C. A. HOWES

Introduction

In Europe, the White-clawed Crayfish Austropotamobius pallipes was formerly widespread in France, Spain and Italy, but populations are now confined to a diminishing number of areas and it is classed as Globally Threatened by IUCN and WCMC.

In Britain the white-clawed crayfish is our only native crayfish and is our largest freshwater invertebrate. It lives in clean, relatively hard, mineral-rich waters with a pH of between 7 and 9 and calcium concentrations above 5mgL -1. It is widespread in clean, calcareous streams, rivers and lakes in England but many populations have been lost since the 1970s.

Due to this decline, in the UK the white-clawed crayfish achieved legal protection in 1986 through its addition to Schedule 5 of the Wildlife & Countryside Act 1981 (in respect of taking native crayfish from the wild). It is also covered under Schedule 9 of this act, making it an offence to release into the wild, or allow to escape, all three species of non-native crayfish in the UK.

In 1992 the European Union Directive on the Conservation of Natural Habitats and of Wild Fauna and Flora (92/43/EEC) (the Habitats Directive) listed white-clawed crayfish in Appendix II requiring, amongst other things, Special Areas of Conservation (SAC) to be set up to protect it. Further international recognition of its vulnerability has resulted in its inclusion in Appendix III of the Bern Convention.

Within Britain, to help protect the species from the damaging consequences of the introduction of alien crayfish species, DEFRA (formerly Ministry of Agriculture Fisheries & Food) introduced the Prohibition of Keeping of Live Fish (Crayfish) Order 1996, which designated “nogo” areas for alien crayfish farming and banned the unlicensed keeping of Pacifastacus leniusculus in no-go areas.

The Conserving Natura 2000 Rivers protocol led to the Life in UK Rivers project which developed methods for conserving the wildlife and habitats of rivers – this project includes the monitoring the white-clawed crayfish.

The White-clawed Crayfish has now been identified as a priority species in the Biodiversity Action Plans of at least 12 planning Authority in the Yorkshire region.

As a result of the above mentioned legislative and conservation protocols the YNU has provided records and data on former distribution of the White-clawed Crayfish in Yorkshire waters to a large number of planning authorities, statutory organisations, conservation bodies, academics and ecological consultancies.

Within the last decade the White-clawed Crayfish has been the subject of numerous site and river catchment surveys within the Yorkshire region, the results of which are being collated the Environment Agency.

The following Gazetteer and Bibliography is made available here to provide background information for current and future studies and to help provide a baseline against which status changes can be compared.
