Extended Phase 1 Habitat Survey

Comprehensive ecological assessment. Often required for planning applications

Our experienced ecologist will provide an Extended Phase 1 Habitat Survey following the Joint Nature Conservation Committee’s Environmental Audit Guidelines 2010 and the Institute of Environmental Assessment’s Guidelines for Baseline Ecological Assessment, 1995.


The Phase 1 Habitat Survey provides the user with a basic assessment of habitat type whilst the ‘extended’ component details the potential value of the site for nature conservation and protected species.


Each habitat type / feature is identified by way of a brief description. It is allocated a specific name, an alpha-numeric code, and a unique mapping colour.



   A site visit that maps out site habitats, including photographs and using the JNCC habitat categories

   Identification of the dominant species within the site and position of species within each habitat.

   Target-noting of features of ecological significance or those unable to be mapped.

   Produce a Phase 1 habitat category results map including key using the JNCC habitat mapping palette.

   Supply a written report that documents the survey results, habitats, assessment details and recommendations including a clear, concise non-technical summary.

   Desk study including any protected sites within 1km and any records of legally protected or notable species within 1km.

   Protected species habitat assessment.

   Biodiversity action plan habitat assessment including reference to UK and Local BAP reports throughout.

   Invasive species survey.



We can also undertake dedicated protected species surveys where they are deemed necessary. All protected species surveys follow industry best practise survey guidelines, including seasonal restrictions on when certain surveys can be undertaken.


Selected Projects

  • Habitat creation for Natterjack toads, with NCC and British Herpetological Society in West Cumbria.  Assessment, Creation, Transfer.
  • Coastal dune stabilisation, West Cumbria.
  • Wildlife habitat creation, nature study centre and interpretation trail, Drax, North Yorkshire.
  • Steel Valley Walk, Stocksbridge, schools involvement, Community Woodlands Officer appointment.  Wildflower meadows were created with the help of local children.
  • Woodland planting for screening and nature conservation.
  • Phase 1 habitat surveys and ecological improvement schemes.
  • Preparation of a 25 year Environmental Audit of all habitats on Heriot-Watt University’s Riccarton campus.  Incorporating studies of birds and aquatic fauna by others.
  • New ponds and meadows for the West Student Village at Heriot Watt University.
  • Invasive species survey for Giant Hogweed, Japanese Knotweed, Himalayan Balsam and Method Statement for remediation
  • River Thames Japanese Knotweed eradication, retired flood defence scheme, habitat creation of Willow Carr

The presence of legally protected species of plants and animals on a development site can have significant implications for project timings and costs.  Follow these guidelines to keep costs down.

  1. Choose sites of low wildlife value if possible  – it will have fewer ecological issues.
  2. Incorporate arboriculture and ecology at an early stage. Your design should fit the surrounds not vice versa. Small design changes can reduce arboricultural and ecological impacts and costs considerably.
  3. Submit all the ecological information to the planners early. Failure to do so can lead to costly delays.
  4. Plan in time for seasonal surveys. Protected species surveys can only be carried out at certain times of year. Make sure you know when. (See Survey Season Guidelines)
  5. Manage your site during the pre-development period. Disused sites soon become inhabited by wildlife.
  6. Enhance your site cost effectively. Planning policy often requires ecological enhancement measures. There are ways to achieve this without running over budget.
  7. Listen to your ecological consultant and avoid short cutting their advice. We don’t recommend that you do things unnecessarily. Early and thorough intervention in a project can save you time, money and headaches.
  8. Read the reports thoroughly. It is important that you know what is required in the way of ecological surveys and mitigation.
  9. Inform your consultant early of any proposed site changes.
  10. Never assume that a site has no ecological constraints. Protected species are quite widespread and commonly encountered during development, including some urban sites.
