Preliminary Ecological Appraisal Guidance for Development

Preliminary Ecological Appraisal (PEA) surveys identify protected species, habitats, and other ecological features that could be impacted by a proposed development. By conducting a PEA survey, developers and planners can detect potential ecological issues early in the planning process, ensuring compliance with environmental regulations and fostering biodiversity conservation.

The insights obtained from PEA surveys assist in designing mitigation measures, informing Ecological Impact Assessments (EcIAs), and supporting sustainable development practices throughout the UK. By integrating ecological considerations into the planning process, a PEA helps balance development needs with the imperative to protect and enhance the natural environment.

The Preliminary Ecological Appraisal process

The process of conducting a Preliminary Ecological Appraisal (PEA) survey in the UK typically involves two key steps to ensure a detailed evaluation of any ecological constraints a proposed development may face. Here is an overview of the PEA survey process:

1. Ecological desk study:
• Data gathering: Collect existing ecological data from sources such as local biological records centres and previous ecological reports.
• Literature review: Review relevant literature, including local biodiversity action plans, designated sites (e.g., Sites of Special Scientific Interest, Special Areas of Conservation, and Special Protection Areas), and historical ecological data.
2.  Extended phase 1 habitat survey:
• Habitat mapping: Conduct a site visit and walkover field survey to map habitats on the development site using Phase 1 Habitat Survey methodology.
• Species list: Identify and record plant species and any signs of protected and notable species (e.g., nests, burrows, droppings). This information can then be used to determine whether any further surveys for protected species may be required.
• Photographic evidence: Take photographs to document habitat types and notable features.

Further Preliminary Ecological Appraisal guidance can be found on the CIEEM website.

When is a Preliminary Ecological Appraisal required?

If a development has the potential to impact biodiversity on a site, an ecological impact assessment of the site will usually need to be carried out. Preliminary ecological appraisals should be carried out before the submission of planning applications. We would advise that pre-application discussions with the local planning authority are undertaken to find out if a site survey is required.

When considering a planning application, the local planning authority will consider how the impacts of the development on the environment and biodiversity of an area. It will also consider the presence of any notable species or habitats present on the site.

If it is determined that the proposed development could affect species and habitats in the area, mitigation methods will be required to be put in place before the proposal can be granted planning permission. This is done to support protected species in the surrounding area and ensure no further harm is caused.

Conducting a PEA at the early stages of a project not only enables a smoother planning process but also promotes sustainable development by safeguarding the UK’s rich and diverse ecological heritage. It is an integral part of responsible development, balancing the needs for growth and infrastructure with the imperative of conserving the natural environment for future generations.
