Preliminary Ecological Appraisals Surveys

 
Preliminary Ecological Appraisals

Ecological appraisals are an in depth survey of a site that gives a full overview of the site’s potential to support protected species and habitats and outlines any constraints to potential development.

Background Information

While called Preliminary Ecological Appraisals (PEA), they are also sometimes called Ecological Assessments, Scoping Surveys, Extended Phase 1 or Protected Species Scoping Surveys.

A PEA is used as a starting point for gathering ecological information about a site, highlighting any areas for further survey, such as target species surveys.

The appraisals incorporate methodologies from other habitat surveys, such as phase 1, walkover surveys and arboricultural assessments, but they are more detailed and give more information about potential impacts to the ecology from any proposed works and can help inform mitigation strategies.

Survey Methodology

A systematic and detailed site assessment is undertaken using methods from the phase 1 survey with habitats marked on a site plan and a species list written. Any trees or buildings on site will be shown on the map and visually assessed for their condition and potential to support protected species such as bats. Any buildings on site will also be assessed for potential to support roosting bats.

All habitats present on site will be mapped. Each habitat will be assessed for its suitability for utilization by protected species and any signs of protected species encountered will be mapped using a GPS handset.
