Preliminary Ecological Appraisal Habitats on site will be assessed for their suitability to Priority invertebrate species during the initial Preliminary Ecological Appraisal.
Butterfly Surveys Where suitable habitats are identified, further butterfly surveys will be recommended, specific to the species targeted. A surveyor will carry a walkover survey during suitable weather conditions to identify, count and map butterfly species present, using a butterfly net where necessary for closer inspection. In some cases, such as surveys for white letter hairstreak, egg searches may be more appropriate.
Reporting Results of butterfly surveys will typically be incorporated into existing preliminary ecological appraisal reports, providing impact assessment and recommendations for mitigation and/or compensation.
