Extended Phase 1 Habitat Survey

An Extended Phase 1 Habitat Survey (EP1HS) (sometimes called a Preliminary Ecological Appraisal (PEA)) is usually the first ecology survey completed at a proposed development site.

It is during this survey that potential ecological issues that may affect the granting of planning permission are identified and that the requirement for further surveys is determined. 

An EP1HS usually includes:

  • An initial desk study to identify nearby sites designated for their biological interest and to obtain biological records data from the local area.
  • An ecological walkover survey ofthe proposed development site and adjacent areas to:
  • map broad habitat types;
  • determine the presence/likely absence of notable and protected species;
  • identify the presence of controlled plant species (e.g.. Japanese Knotweed); and
  • Production of an EP1HS report, including recommendations for further ecological surveys and ecological enhancements, suitable for inclusion with planning applications.

BiOME has completed EP1HSs in relation to many development proposals from extensive upland sites to brownfield land in urban areas. 

The knowledge and experience that we bring minimises the risk that potentially significant ecological issues are overlooked which could lead to costly delays.
