Creation of a White-clawed crayfish Ark Site in the Yorkshire Dales

White-clawed crayfish Ark site creation: Yorkshire Dales.
GSL Ecology worked with a major mineral extraction company to create a white-clawed crayfish ark site within a former limestone quarry in the Yorkshire Dales.
The creation of Ark sites is now recognised as an essential part of the white clawed crayfish conservation strategy for England and Wales.
The project aims to establish a self-sustaining population of white clawed crayfish in this isolated quarry site, safe from non-native crayfish and crayfish plague.
Other work undertaken on the site included breeding bird surveys; protected species scoping survey; NVC botanical survey; ecological input to site restoration design; and ongoing monitoring of establishment of habitats within the site.
