Preliminary Ecological Appraisal
Ecological field surveys often begin with a Preliminary Ecological Appraisal or Extended Phase 1 Habitat Survey. Within the survey area each parcel of land is classified, recorded and mapped in accordance with a list of ninety specified habitat types using standard colour codes. This allows a rapid visual assessment to be made of the extent and distribution of different habitat types. ‘Target Notes’ are used to provide supplementary information on features which are particularly interesting or significant, or too small to map, and to provide additional details, for example relating to species composition and structure.
