Phase I surveys are one of the most common ecological surveys carried out. Using
standard methodology they identify and map the habitats on site and are usually extended
to include detailed protected species recording as well as an assessment of the suitability of
the habitats to support protected species. The surveys and reporting are relatively quick
to complete and provide valuable information for submission with planning applications as
well as identifying any constraints that may be associated with a particular project, which
can help avoid costly delays at a later stage.
Walkover surveys are a quicker, scaled down version of a Phase I Habitat Survey. They
identify potential constraints and are useful to inform possible acquisition of sites or
potential developments. Walkover surveys are generally not considered comprehensive
enough for submission with planning applications.
Botanical Surveys
Habitats of particular interest may require a more detailed botanical survey. This is
usually carried out to National Vegetation Classification (NVC) standards. These surveys
not only identify the plant communities present but will also bring to light any rare or
protected plant species on any given site.
Hedgerow Surveys
Hedgerows are the subject of their own legal act and specific surveys may be required if
hedgerows are to be impacted on by development. Hedgerow surveys are used to identify
'important' hedgerows in accordance with the Hedgerow Regulations (1997).
