Crayfish Surveys

Estrada Ecology consultants are fully licensed and experienced in surveying for the species.

The white-clawed crayfish is Britain's only native crayfish and is protected under European and UK legislation. It is widely distributed in England, mid-Wales and Ireland.

They are largely nocturnal, with breeding taking place from September to November when water temperatures drop below 10°C for an extended period.

The white-clawed crayfish lives in a diverse variety of clean aquatic habitats but especially favours hard-water streams and rivers.

There is only a short period of time in a year when Crayfish surveys can be carried out, the optimal time is July to Sept. Surveys cannot be carried out during winter months due to the lack of activity.
