What is a PEA and why do you need one?

A Preliminary Ecological appraisal, or PEA, is an essential first step in the planning process for most development projects. It involves a thorough assessment of the ecological condition of a site, identifying any potential impacts your proposed development may have on habitats or protected species and highlighting the need for any further survey work.

What does a PEA involve?

A PEA typically involves two key stages:

• Desk Study: This phase involves gathering existing information about the site and its surroundings. This includes consulting ecological databases, historical records, and relevant mapping resources to identify known or potential habitats, protected species records and designated sites. It will also determine the local planning policy requirements that are applicable to the site.
• Field Survey: A qualified ecologist will visit the site to assess the habitats present, their condition, and the presence of or potential for protected species. This involves visual observations, taking photographs, recording plant and animal life, and searching for signs of species activity like badger setts or trees with bat roost potential. If your site has a building, we will also conduct a Preliminary Roost Appraisal (PRA) for bats. Surveys can be conducted at any time of year but are best conducted during the growing season from April to September.

Outcomes of a PEA

Following the desk study and field survey, a comprehensive report is prepared that outlines the findings. This report typically includes:

• A description of the identified habitats and their ecological value.
• An assessment of the potential presence of protected species and potential impacts on them as a result of your proposals.
• A Phase 1 or UKHab plan/habitats map with Target Notes indicating key ecological features.
• Recommendations for any further, more detailed ecological surveys that may be required.
• Mitigation measures to minimise potential impacts on the site’s ecology.
• Opportunities for incorporating ecological enhancements into the project design.

We recommend that you have a PEA carried out as early as possible, even if you don’t yet have formal plans. Identifying ecological constraints early in the planning process allows you to proactively address potential issues, reducing the risk of costly delays (due to the seasonality of some surveys), or objections during the planning application process.

Breakwell Ecology have extensive experience in conducting PEAs and bring a personalised approach to every project. We will guide you through the planning process, providing practical solutions to help secure the success of your development project while protecting our natural environment.
