This is the baseline survey that is used to identify which natural habitats are present on a site and can highlight any evidence of protected or invasive fauna or flora. From this point the assessor can decide whether any further, more specific, surveys are required. 



Types of Phase 1 Habitat Survey


Phase 1 Habitat Survey

The Phase 1 surveying method is a system that was developed to provide a record of the vegetation and habitats over a specific area. The surveys are undertaken following the Phase 1 survey methodology (JNCC, 2010), listing the plant species associated with each habitat.

A phase 1 survey provides a base line and a means of evaluation upon which further ecological surveys may be based.

Extended Phase 1 Habitat Survey

An Extended Phase 1 Habitat Survey follows the same JNCC methodology but also includes an assessment of the site for protected species, species of conservation concern and suitable habitat by combing the phase 1 with a preliminary protected species walkover. Habitats on a survey site are recorded onto a base plan and any habitats that are considered to be of potential interest to nature conservation, are recorded through the use of target notes to annotate a Phase 1 habitat map.

Desk Study

A desk study can also be completed in conjunctions with an Extended Phase 1 Survey. The desk study includes purchasing data from the local biological records office and consultation of online sources including the National Biodiversity Network, MAGIC and local authority websites. Consultation with statutory bodies and local recording groups such as bat and ornithological groups can also be undertaken.

When is an Extended Phase 1 Survey Required?

A Preliminary Ecological Appraisal / Surveys are often required by a planning authority as part of a planning application. The Phase 1 / Extended Phase 1 Survey provide a baseline for planning and technical reports will be produced to support our client’s applications.

Technical reports provided following the site survey includes the following information:

  • Habitats present on site and their significance;

  • Species or potential species present and their significance;

  • Assessment of value of the habitats or species present;

  • Potential impacts of work on the species or habitats;

  • Legal and planning policy issues that may arise that should be addressed; and

  • Recommendations for additional surveys, appropriate mitigation, compensation and enhancement.

Extended Phase 1 Habitat Surveys can be undertaken at any time of the year.
