Phase 1 habitat surveys are a technique for environmental audit.  Phase 1 is a system of habitat classification that is widely recognised within environmental and planning disciplines. 

Phase 1 habitat surveys are regularly undertaken to assess habitats.  Extended Phase 1 surveys, identify the potential for protected species, record invasive species or any other significant ecological interest within a site, and the surrounding area.
