Vegetation (NVC) Surveys

When do I need a Vegetation (NVC) Survey?

Vegetation surveys, sometimes called Phase 2 Habitat Surveys or National Vegetation Classification (NVC) Surveys, may be required where priority or potential protected habitats have been identified on site or in adjacent lands during a Preliminary Ecological Appraisal (PEA) or an Extended Phase 1 Habitat Survey.

What is a Vegetation (NVC) Survey?

An NVC Survey is an industry standard method of identifying and classifying habitat types. This method is described by JNCC (2006) here.

Using this method habitats and plant communities are classified based on species assemblages identified in sample quadrats in distinct habitat areas. The survey provides a high level of information about the species composition and diversity present which can be used to inform mitigation and compensation measures where habitats are to be relocated, recreated or enhanced.

How long will it take?

When considering the completion time for Vegetation (NVC) Surveys it is important to remember the differing seasonal restrictions that apply for this type of survey for different habitat types:

Woodland NVC Surveys:

As the maximum species-richness occurs in the spring before the leaves appear on the trees these surveys can only take place from mid-April to June.

Wetland NVC Surveys:

As the maximum species-richness occurs in the summer when aquatic plants have had a chance to grow these surveys can only take place from June to August.

Peatland NVC Surveys:

As the maximum species-richness typically occurs in mid-late summer many of these surveys can only take place from June to September.

Grassland NVC Surveys:

As the maximum species richness occurs in the summer these surveys can only take place from June to August.

Cost: From £550*
