Preliminary Ecological Appraisal Derbyshire: Collington Winter

What is a Preliminary Ecological Appraisal?

A Preliminary Ecological Appraisal (PEA) should be the first step you take in evaluating a site. An Ecological appraisal will provide an overview of a site, which can help you to understand the ecological conditions. This can include the presence of any protected species, details of any habitats present or any other key ecological constraints which could affect your projects.

The two main elements of an ecological appraisal include an extended Phase 1 habitat survey and an ecological desk study.

When is a Preliminary Ecological Appraisal Required?

If a development has the potential to impact biodiversity on a site, an ecological assessment of the site must be carried out. Preliminary ecological appraisals should be carried out before the submission of a planning application.

We advise that discussions with the local planning authority are undertaken to determine whether an ecology survey is required.

How Can Collington Winter Assist Your Project?

Collington Winter are able to assist your project by undertaking ecological desk studies, as well as extended phase 1 habitat surveys.

Ecological Desk Study:  Collington Winter provide an ecological desk study service, obtaining records and data on designated sites. We undertake research on legally protected sites and obtain records on protected species within the area of the site. We are then able to provide printed or interactive maps using GIS using the data provided.

Extended Phase 1 Habitat Survey: Using extended phase 1 habitat surveys, we can identify any key ecological issues. We can also provide guidance on how to best resolve the ecological issues identified.

We use the extended phase 1 habitat survey technique to map habitats present on-site and within the surrounding area. This can determine whether further specific surveys must take place, such as bat surveys or great crested newt surveys.

We can also assist with ecological impact assessments and protected species surveys.
