Wren Ecology can offer the following habitat surveys to its clients to support their planning applications and other requirements:

Phase 1 Habitat Survey:

A ‘Phase 1 Habitat Survey’ records the wildlife habitats (both urban and rural) and vegetation that a site supports, through an industry-approved classification technique that includes colour mapping of the survey site.

This survey technique has been devised by the Joint Nature Conservation Committee and is widely used throughout the UK by ecological consultants. It is recognised by both environmental and local planning sectors to support planning applications and can identify the requirement for any any subsequent habitat-specific surveys to identify flora or habitat features of nature conservation value.

Extended Phase 1 Habitat Survey:

An ‘Extended Phase 1 Habitat Survey’ comprises both a Phase 1 survey and also records any evidence of species habitation or utilisation of the survey site. It will record and map the habitats that support or have the potential to support legally protected faunal species or those of conservation concern.

In addition to the habitat findings provided by this survey, an Extended Phase 1 survey can help clients inform their development programmes when it comes to any requirement for further habitat or species specific surveys, mitigation measures and construction phase timings.


Surveying of Hedgerows for their Ecological Value:

A survey of hedgerows to confirm their ecological value in respect of the criteria set out in The Hedgerows Regulations 1997 can also be carried out to support planning applications.


Survey Timing:

All the above surveys should be carried out during the months of April through to September in order that as many flowering species and evidence of faunal activity can be identified. Surveys can be undertaken outside of these months, but may be limited in habitat/species identification; in such cases it is prudent to ascertain whether the relevant Local Planning Authority or Statutory Stakeholder will accept survey findings outside of these optimal months.


A report will be produced after completion of the habitat survey, which can be used to support the site’s planning application. Where necessary, the report will also include any requirement for further species/habitat specific surveys and recommended implementation of mitigation measures to avoid direct/indirect impacts to habitats and/or species during the proposed construction/works phase.
