Classification of Natural Communities (Fourth Approximation)

Draft descriptions for the 4th approximation communities are offered for use and feedback. We welcome feedback on the 4th approximation, including on the draft descriptions and the classified communities.

Detailed descriptions are available at two levels of the classification. Subtypes, the finest level, are the units tracked by the Natural Heritage Program, and are generally equivalent to associations in the National Vegetation Classification. Four-digit codes next to the names are the “CEGL codes” (NVC Codes) that identify the most equivalent association. Descriptions are also being written for themes, the coarsest level in the 4th approximation. Themes are broad ecological groupings containing several community types and subtypes. Theme descriptions contain material that is common to all or most of the types and subtypes they contain, to avoid repeating this material in multiple subtype descriptions.

To contribute input, please note the subtype and NVC code. Send all comments to michael.schafale@ncdcr.gov.
