Preliminary Ecological
A Preliminary Ecological Appraisal (PEA) is a type of biodiversity survey.
Preliminary Ecological Appraisal is sometimes referred to as an Extended Phase 1 Habitat Survey or Phase 1 Ecology Survey, and is the first stage in assessing the ecological value of a site and enables identification of features of particular ecological interest.
The appraisal comprises a rapid assessment to identify features of ecological interest on-site or within the vicinity of the site to understand the potential ecological impacts that may be caused by a proposed project.
The rapid assessment includes:
- A desk study to provide background data and context.
- A walkover of the site is completed to classify and map the habitat types that are present.
- Looking for evidence of or potential for protected species within or adjacent to the site.
A Preliminary Ecological Appraisal can be undertaken at any time of the year, although the optimal time for the Phase 1 Habitat Survey is from April to September, inclusive.
