Preliminary Ecological Appraisal in Kent

As one of England’s most economically diverse counties, developments in Kent often face sustained development pressure. A Preliminary Ecological Appraisal (PEA) is often a routine and important part of the planning process across Kent.

The diversity of Kent’s landscapes means ecological constraints vary considerably across the county. Common constraints identified in preliminary ecological appraisals across Kent include:

• Bats – the county’s historic oast houses, barns, churches, and mature parkland trees provide significant roosting potential across a wide range of site types
• Great crested newts – widespread across lowland Kent wherever suitable pond habitat exists within 500 of a development site
• Reptiles – brownfield sites, coastal grassland, and heathland remnants support populations of common lizard, slow worm, and grass snake
• Otters and Water voles – present along the River Stour, Medway, Darent, and associated drainage networks, particularly in low-lying areas around Romney Marsh

This is not an exhaustive list. Every site is different, and a thorough desk study and field survey will establish which constraints are relevant to your specific proposed development.

Collington Winter provides Preliminary Ecological Appraisal across Kent, from desk study through to field survey and report production. Our ecologists understand both the regional ecology and the expectations of Kent’s local planning authorities, producing proportionate, clearly evidenced reports that support planning applications and identify and further species surveys required at the earliest possible stage.

How do I know if my site needs a Preliminary Ecological Appraisal?
The most reliable way is to seek early advice from a qualified ecologist or to raise it during pre-application discussions with your local planning authority. As a general rule, if your site includes features such as trees, hedgerows, ponds, watercourses, old buildings, or scrubland, a PEA is likely to be required before your planning application can be determined.

How long does a PEA take to complete?
Most PEAs can be completed within two to three weeks of the site visit being carried out. Timescales can be affected by site size and complexity, as well as the availability of records from local biological record centres. Instructing early in the planning process avoids these factors becoming a source of delay.

What happens if protected species are identified during the survey?
The PEA report will identify the species and recommend appropriate follow-up surveys. Depending on what is found, a licence under the Wildlife and Countryside Act 1981 or the Conservation of Habitats and Species Regulations 2017 may also be required before any works affecting those species or their habitats can proceed.

Does a PEA have an expiry date?
Yes. Most local planning authorities expect ecological survey data to be no more than two to three years old at the point of application submission. If your site has changed materially since the original survey – through vegetation clearance, building works, or changes in land management – an updated assessment may be required regardless of when the original PEA was carried out.
