Certain invertebrates are subject to protection under the Wildlife and Countryside Act 1981, while others are listed under Section 41 of the Natural Environment and Rural Communities Act 2006. Entomology is a complex subject, but Ecology Solutions is able to call on experts in their field for survey and assessment. In a development context, invertebrate interest is often encountered on brownfield sites to be subject to redevelopment. Ecology Solutions is able to advise on suitable mitigation strategies, and negotiate with the relevant authorities to agree the approach.White-clawed Crayfish is protected under the Wildlife and Countryside Act; it is the native freshwater crayfish species, much reduce in range as a result of the spread of the American Signal Crayfish. Surveys may be required where development affects suitable streams within the range of the species.Surveys for invertebrates are undertaken across the spring and summer seasons, with a series of visits generally required to gain a full appreciation of the interest present. Surveys for White-clawed Crayfish are undertaken from mid-July until mid-September.
