Phase 1 Habitat Survey
Phase 1 habitat survey is a standard technique for the rapid appraisal of habitats at a site. This type of survey is often sufficient to establish the presence or absence of protected habitats, although when habitats with a high conservation value are present, it may be also be necessary to classify these in more detail through an NVC (Phase 2) survey.
Extended Phase 1 Habitat Survey
An extended Phase 1 habitat survey is often the first step undertaken in the initial appraisal of the possible ecological issues at a prospective development site. As such, this type of broad reconnaissance survey is invaluable for screening and scoping purposes.
The standard Phase 1 habitat survey is extended to include an assessment of the potential of the site to support protected animals. Such species are often difficult to see but the likelihood that these occur can often be predicted, through knowledge of their local distribution, habitat requirements and tell-tale field signs (such as feeding remains, droppings, nests, etc).
National Vegetation Classification (NVC) Habitat Survey
NVC survey categorises the plant communities of an area very precisely, based on the full range of plant species present. It is particularly valuable for establishing the quality and distribution of habitats that are specially protected under the EU Habitats Directive, or that are priority habitats within the UK Biodiversity Action Plan or Local Biodiversity Action Plans.
A key application of this information is to guide the micro-siting of development features, that may be needed to avoid undue damage to a protected habitat.
Clyde Ecology and its associates offer both Phase 1 and NVC habitat surveys.
