Preliminary Ecological Appraisal (PEA)

PEA's are a phase 1 survey performed before any development to assess the potential for protected species to use a site and to inform any future surveys that will be necessary for development to continue without compromising on the environment.



Why are PEAs carried out?

Preliminary Ecological Appraisals (PEAs) are an invaluable tool for assessing impacts, monitoring and planning mitigation, or enhancement for a site. The survey can also be used to inform future monitoring and updating if it is required for further development of the site.


When do I need to have a PEA?

Phase 1 surveys can be undertaken all year round; however, they are best undertaken in spring and summer. We would always advise commissioning such a survey well in advance when planning your site development, to allow time for any necessary targeted surveys for protected species, which are often restricted to specific times of year.

What does Abrehart Ecology offer?

At Abrehart Ecology we offer professional, skilled, and efficient PEAs. We undertake in-house fieldwork and expert report writing, with our employees.

Our Phase 1 and PEA surveys provide clients with an overview of the habitats present, a comprehensive list of plant species for their site (depending upon the time of year) and is often extended to include the potential of a site to support legally protected species. 

Biodiversity Net Gain (BNG)

With new legislation coming into force during 2024, BNG will need to be carried out as part of phase 1 surveys, alongside PEAs, for large devlopments from 12 February 2024, and small developments from 2 April 2024.
