For larger developments, a PEA or extended Phase 1 Habitat survey provides an ecological baseline.

A Preliminary Ecological Appraisal (PEA), previously known as an extended Phase One Habitat Survey, provides a standardised system to record semi-natural vegetation and other wildlife habitats. The approach is designed to present an initial assessment of habitat type and potential importance for nature conservation.
The survey comprises a comprehensive walkover and is typically conducted on larger development sites (more than 1 acre). Best undertaken between April and September inclusive, a PEA provides an assessment of habitats and species on and adjacent to the site.
This informs any need for further survey effort and/or mitigation. As part of the survey, a report and map are produced that can be interpreted by the Local Planning Authority to help assess the ecological value of a site.
