Preliminary Ecological Appraisal

Preliminary Ecological Appraisal

Preliminary ecological appraisal (PEAs) is usually the first stage of a site assessment and provide an evaluation of the base line conditions of the site and any habitats associated with the site – including its botanical interest and potential habitats. The main aim of the assessment is a preliminary investigation into whether any further surveys and possible mitigation measures are required.

Preliminary Ecological Appraisal Report

The PEA follows the standard format, documented in a final report:

  • Assess the baseline conditions by using the phase 1 habitat survey guidelines (JNCC 2010)
  • Assess the potential for the presence of protected species, such as the presence of ponds, ancient woodland and hedgerows
  • Identify any potential constraints to the site
  • Identify if further protected species surveys are required or if further specialist vegetation surveys are necessary
  • Provide an assessment of the habitat’s ecological importance
  • Provide recommendations for reducing impacts or highlighting the potential for significant ecological impacts
  • Identify potential enhancement opportunities
  • Mapping
  • Photographs of the site

The Preliminary Ecological Appraisal report provides further recommendations such as further detailed surveys or surveys required to support an Ecological Impact Assessment (EcIA).
