Extended Phase 1 Habitat Survey

Verge Survey
Habitats are mapped in the field and the data is transferred on to a Geographic Information System (GIS).

Initial ecological appraisal

This is the survey method that forms the initial stage of survey (or initial ecological appraisal) on a prospective development site and assesses a site's potential to support protected species or features that may place constraints on a prospective development site. Due to seasonal constraints associated with surveys and potential subsequent mitigation work, it is recommended that these surveys are commissioned as early as possible to identify any ecological constraints. This approach can save both time and resources and helps avoid running in to problems further down the line during the development phase.

Initially, a desktop study is carried out that reviews both publically and privately available data, and identifies records of protected species and neighbouring sites such as Sites Important for Nature Conservation (SINCís) or Sites of Special Scientific Interest (SSSIís) for a defined area around the site.

After this initial study has been carried out, recommendations for future work can be made, however if the site is deemed to have little or no ecological interest then further work may not be necessary.

Invasive Plant Species

As a matter of course and prudence we routinely include an invasive weed survey as part of the Extended phase 1 survey (at no additional cost) and so are able to let our clients know early on if they have any invasive plant issues. The position and extent of the invasive weed are mapped and transferred on to a Geographic Information System (GIS). See our Invasive Plant Species page for more details.
