There are over 40,000 species of invertebrate recorded across the British Isles, whilst around 70 of these receive special protection including white-clawed crayfish, freshwater pearl mussel and lesser silver water beetle. Many are also priority species, including widespread species such as cinnabar moth, garden tiger moth and knot-grass. Where protected or priority species could be impacted by development proposals for an area, avoidance or mitigation strategies are often required to avoid significant impacts.

Tyrer Ecological Consultants Ltd is able to offer specialist surveys for both protected and priority species across a range of terrestrial and aquatic environments for development and other projects. The exact methodologies outlines for individual projects would however, differ dependent upon the habitats available and species likely to be present and would need to be tailored accordingly.
