Preliminary Ecological Appraisals
Preliminary Ecological Appraisals (PEAs) are the most common ecological survey that we undertake. These surveys can also be known as Extended Phase 1 Habitat Survey, a Baseline ecological survey, Phase 1 Survey, Ecological Constraints Survey, Ecological Site Assessment, Ecological Site Appraisal, Ecological Scoping Survey or Ecological Site Walkover Survey. Local authorities will often use these terms interchangeably.
The ecological impact of any development, from small scale domestic projects to national infrastructure projects, should be considered at the planning stage. It is vital that you consider the ecology of your site at the earliest possible stage to allow time for surveys and assessments to be undertaken at optimal times. By considering surveys early costs can be reduced and the risk of delays to the project are minimised.
A PEA consists of a visit to the site to identify habitats and features on the site that may constrain development and desk based survey to gather information about the site and its context in the wider area will be carried out. Data is usually obtained from Local Biodiversity Records Centres. This includes information on protected and Biodiversity Action Plan priority species and the presence of nearby statutory protected areas.
During the PEA the whole site and its boundaries will be assessed and field maps will be annotated with Phase 1 habitat types. Key plant species will also be identified whilst looking for evidence of protected or pest species. Although there is no need for you to be present during the Preliminary Ecological Appraisal, if you have any concerns about site ecology we are very happy to have an informal site meeting at the start, or the end, of the site visit
The outcome of the survey is a clear and concise report including a detailed map of your site describing habitat types present and any features of ecological interest. This is the foundation ecological document for your site and is normally valid for two years from the date of survey.
Where appropriate, recommendations for impact avoidance, mitigation and post-development enhancement are made to ensure compliance with wildlife legislation and relevant planning policy. If it is unclear whether protected species are present or how they use your site, the report may make recommendations for further protected species surveys.
Cost of a PEA
When quoting for a PEA various factors will be taken into account:
Size of the site
Complexity of site habitats
Proximity to external protected habitats
Impact of development
