Ecological Assessment

The baseline survey that tells you what ecology is on your site and what it means for your application.

Typically required for

Most planning applications where habitat, trees or buildings are present

Survey timing

Year-round, though optimal between April and October

Project stage

Pre-application and application

What is it?

An ecological assessment combines desk-based research with a site walkover to characterise the habitats present and assess the potential for protected species. An Extended Phase 1 Habitat Survey maps what is there. Where a scheme is likely to have significant effects, a full ecological impact assessment follows CIEEM methodology to assess those effects against national and local ecological value.

When is it required?

Most local planning authorities expect a baseline appraisal alongside a planning application, and many raise it at pre-application stage. It is also commonly required for permitted development notifications and prior approval submissions.

What happens

  1. 01Desk study of existing ecological records, designated sites and historic mapping
  2. 02Site walkover recording habitats, boundary features and evidence of protected species
  3. 03Assessment of the potential for further species-specific survey
  4. 04Reporting against CIEEM guidelines in a form the planning authority will accept

What happens next

If the appraisal identifies potential for protected species, targeted surveys follow. Those surveys are season-bound, so it pays to know early.
