Habitat surveys

General walkover surveys of sites can be useful to ascertain the key features in terms of wildlife value of a site. The rapid identification of these features can potentially reduce future costs as habitat surveys aim to highlight habitats and species which may require mitigation. These can then be avoided, or a mitigation solution may be found.

Phase 1 Habitat Survey

A Phase 1 habitat survey is a very useful and commonly used tool for quickly assessing the vegetation and wildlife habitat in existence at any particular site. Phase 1 habitat surveys are an assessment technique recommended by Natural England and the Institute of Ecology and Environmental Management.

An Extended Phase 1 habitat survey may also be carried out. This is based on Phase 1 methodology, but is a more detailed survey. It is usually undertaken over a smaller area. The site is surveyed and then vegetation is mapped on to a large scale map. A standard numerical and colour code system is used, as specified by the Joint Nature Conservation Committee (JNCC). The output is a colour coded habitat map which allows rapid visual assessment of the different habitat types present.

‘Target notes’ are produced for each habitat. These provide a habitat description and record of species of conservation concern and suitable habitat for such species. Target notes are an essential for providing more detailed information on sites of interest and those requiring further survey(s).
