Ecological Site Assessment

Our services

This service has a range of other names, such as ‘Extended Phase 1 Survey’ or ‘Ecological Appraisal’. It is typically the first phase of a more detailed baseline study, but for a small project on a simple site, it can provide sufficient information to stand alone. At ESL we consider this assessment to include three stages:

All our in-house ecologists are trained to carry out such assessments, and at least one member of every field team visiting any site will have the necessary Natural England survey licences for any species likely to be found.

Timing of surveys

This level of assessment can be carried out at any time of year, but where necessary the report will recommend that for certain species, more detailed surveys be carried out at the season specified in Natural England guidance.

Senior staff will always explain any seasonal concerns in advance, and will advise on survey timing for particular projects and habitats.

Why carry out Ecological Site Assessments

This study is likely to be required on every site for which planning permission is to be sought, with the level of detail necessary depending on the size of the application and the complexity of the site, but may also be carried out for other reasons. Typical reasons for requesting this type of study may include:

In each case, senior staff will advise on how the basic survey would be adjusted to provide exactly the type and level of information required for the project.
