Extended phase 1 habitat surveys
Conducting an extended phase 1 habitat survey is normally the first step in assessing the ecological value of a site and the likely effects of the proposed development. Local Planning Authorities normally require an extended phase 1 habitat survey to be undertaken where the proposals could impact designated sites, protected habitats or protected species.
Phase 1 habitat survey (JNCC, 2010; CIEEM, 2013) is a standard technique for recording and mapping the habitats present within a development site. The technique is typically “extended” to include an assessment of the potential of the site to support protected species and carried out alongside a desk study to obtain records of designated sites, protected habitats and protected species from third parties, such as local biodiversity records centres and local conservation groups.
