Acer Ecology’s licensed ecologists have carried out Ecological Walkover Surveys in Northumberland.

Walkover surveys are also sometimes called Extended Phase 1 Habitat Surveys.

Alternative names for Extended Phase 1 Habitat Survey are:

  • Phase 1 Habitat Survey,
  • Preliminary Ecological Appraisal,
  • A Baseline Ecological Survey,
  • Phase 1 Survey,
  • Ecological Constraints Survey,
  • Ecological Site Assessment,
  • Ecological Site Appraisal, and
  • Ecological Scoping Survey.

We are well placed to carry out all types of ecological surveys across Northumberland and the surrounding areas of Scotland, Tyne and Wear, Newcastle, Sunderland, Durham, and Cumbria. Usually, the standard Phase 1 Habitat survey methodology is used, whereby colour coded habitat maps are drawn up showing the extent and distribution of the different habitat types present on a site.

Dogwood Ecology Survey

We recently conducted an ecological walkover in Alnwick, the survey identifies habitats and features on the site that may constrain development and evaluates the potential of these habitats to support protected species. If the site is assessed as having low wildlife interest, then no further surveys may be needed. If necessary, clients are advised to undertake more detailed specialist studies of the site.

A data trawl is usually undertaken in conjunction with the survey, whereby information about the site and its context are obtained from organisations such as Local Biodiversity Records Centres. This includes information on protected and Biodiversity Action Plan priority species and the presence of nearby statutory protected areas.
