The National Vegetation Classification (NVC) is a standardised method for identifying plant communities.

An NVC Survey is carried out when a more detailed analysis is required than the basic Phase 1 Habitat Survey. This may be because a habitat of high potential conservation importance has been identified, and confirmation of their extent and value is required.

Records of the abundance and frequency of plant species on the site are obtained through the use of standardised sample quadrats. These records are then used to map the habitats on site, divided into a mosaic of vegetation assigned to specific NVC sub-communities.

An NVC map is generally created using a Geographic Information System (GIS), which allows area calculations to be made for each habitat type.

NVC Surveys should take place between April and September (see Survey Calendar).
