Preliminary Ecological Appraisals (PEA)
What is a Preliminary Ecological Appraisals (PEA)?
A Preliminary Ecological Appraisal (PEA) is usually the starting point for most planning applications where development may affect semi-natural habitats. At Whitcher Wildlife Ltd, we use PEAs to provide an initial overview of a site’s ecology, identify any ecological constraints, and advise on whether further, more detailed surveys are needed before a planning application is submitted.
PEA Survey Process
Our PEAs are carried out in line with the Chartered Institute of Ecology and Environmental Management (CIEEM) Guidelines for Preliminary Ecological Appraisal (Second Edition, 2017) and use the UK Habitat Classification (UKHab) Version 2.0. We assess the habitats present on site, along with the presence, or potential presence, of protected or notable species and invasive non-native plants. In most cases, our surveys are supported by a desktop data search obtained from the local ecological records centre.
Our findings are presented in a clear, easy-to-understand report prepared for the developer and design team. This includes habitat maps, an assessment of the ecological value of the site, any protected or notable species recorded (or likely to be present), and practical recommendations for further surveys, mitigation, enhancements or design changes that may be needed to support the planning process.
Survey Timing & Next Steps
PEAs can be carried out at any time of year, although some habitats and species require surveys at specific times. For example, grassland surveys are usually undertaken in mid-summer, woodland surveys in spring, and heathland surveys in autumn. Many protected species also have strict survey seasons and methods, such as great crested newts, which require spring pond surveys, and bats, which require dusk and dawn surveys during the spring and summer months. Where relevant, our PEA reports clearly set out what further surveys are required and when they should be carried out.
For simpler sites, a PEA may be sufficient on its own to support a planning application. However, for more complex developments, or where significant ecological impacts are identified, the PEA is often supplemented by an Ecological Impact Assessment (EcIA), which Whitcher Wildlife Ltd can prepare to support the final planning submission.
Why choose us for your Preliminary Ecological Appraisals (PEA)?
Our team has extensive training and experience in carrying out PEAs across a wide range of habitat types. Where additional surveys are needed, Whitcher Wildlife Ltd works closely with the design team to set out clear, realistic survey timescales and to advise on any changes to the site layout or design. We also provide guidance on appropriate mitigation and enhancement measures to help reduce ecological impacts and ensure that proposals align with the requirements of the National Planning Policy Framework (NPPF).
