Ecological surveys

Preliminary Ecological Appraisal

A Preliminary Ecological Appraisal is usually the first survey to be undertaken. The ecologist will assess the habitats and features in and around a site, identify the potential ecological constraints and make recommendations, which may include the need for ecological mitigation measures or for more detailed ecological surveys to be carried out.

The appraisal should be informed by an up-to-date biological records search from the Kent and Medway Biological Records Centre (KMBRC).

More information about what is included in a PEA report can be found within the CIEEM Guidelines for Preliminary Ecological Appraisal.

Species surveys

Any additional species surveys, as identified in the PEA, need to be undertaken and the results and any necessary mitigation proposals submitted with the planning application. The surveys and outcomes can be reported as stand-alone survey reports, or by incorporation into an Ecological Impact Assessment report. The results of further surveys are important to inform mitigation strategies and the development proposal’s design, for which you should demonstrate how ecological survey outcomes and recommendations have been incorporated. This also ensures that all the ecological impacts can be addressed in the planning decision, in accordance with Government guidance, legislation and planning policy.

The time of year when further surveys can be carried out is often restricted to when species are most active or visible and can also be further constrained by weather conditions. Natural England’s Standing Advice includes a protected species survey timetable for guidance, and your ecological consultant will be able to provide specific advice.

Ecological Impact Assessment (EcIA)

Larger or more complex developments are typically informed by an Ecological Impact Assessment (EcIA). This assessment is more detailed than that of a PEA and incorporates the findings of further surveys, an evaluation of the effects of the proposals upon important ecological features and recommends mitigation solutions (avoidance, mitigation and / or compensation measures) to address conclusions regarding the likely impacts on ecological features. You should demonstrate in your planning submission that mitigation recommendations will be incorporated into your development proposals.

The EcIA should provide enough detail and clarity to ensure planning decisions are based on robust adequate information.

More information about what needs to be included within an EcIA can be found within the CIEEM Guidelines for Ecological Impact Assessment and the EcIA Checklist.
