Preliminary Ecological Appraisals

The aim of a Preliminary Ecological Appraisal (P.E.A) is to outline the current vegetation and  habitats on site following under guidelines set out by the Joint Nature Conservation Committee (JNCC) and to assess the potential impacts to habitats and species that could be using the site.

Wallace Darwin will assess your development site to determine; What species and habitats currently occupy the site, what is the base line conditions of site (requirement for Biodiversity Net Gains), what protected species may potentially inhabit the site, and what the impacts will be and how they can be mitigated. 

Our P.E.A's include 

  • A walkover assessment of the site which includes a preliminary roost assessment for bats and birds if a building is located on site and Habitat Suitability Index for Great Crested Newts if water bodies are located on site 

  • A phase 1 habitats map with habitats in either JNCC classification or UKHAB.

  • A detailed report illustrating findings, recommendations and enhancements that could be included within the project.

Should any features be identified to contain the potential to support protected species by our experienced surveyors, then the appropriate protected species presence/absence surveys will be necessary to outline the impact of the proposed works on the land.
