Invertebrate surveys: Freshwater and terrestrial
Invertebrates are critical to biodiversity. They facilitate processes such as pollination and form vital links within eco-systems.
Owing to their importance and general decline, invertebrates receive various levels of protection. The Wildlife and Countryside Act 1981 protects 69 species of invertebrate, including the white-clawed crayfish.
RSK’s experienced ecologists can conduct invertebrate surveys and develop cost-effective mitigation schemes that meet clients’ ecological obligations and commercial needs. An initial survey identifies and assesses potential invertebrate habitats. If necessary, a detailed survey using the most appropriate survey technique follows.
The white-clawed crayfish, the UK’s only native freshwater crayfish, is in serious decline. Consequently, there are numerous statutory instruments for protecting and preserving its habitats. A relevant licence held by a qualified ecologist is required to trap this species for survey purposes and a separate licence from the Environment Agency is needed for the use of crayfish traps under the Salmon and Freshwater Fisheries Act 1975.
