FGDC invites public comment on draft National Vegetation Classification Standard, Version 2

Information about the draft National Vegetation Classification Standard, Version 2.0

The draft National Vegetation Classification Standard, Version 2.0, supports the development and use of a consistent national vegetation classification (the “NVC”) in order to produce uniform statistics based on vegetation data gathered at local, regional, or national levels.

This Standard establishes national procedures for classifying vegetation that Federal agencies shall use to share vegetation information and facilitate reporting of national statistics. It requires that all Federal vegetation classification efforts meet core data requirements to permit aggregation of data from all Federal agencies. The Standard also requires that vegetation mapping and inventory units crosswalk to the NVC, meaning that the composition of any map unit or inventory unit shall be described in terms of one or more vegetation types at an appropriate level of the NVC hierarchy.

This Standard shall not preclude alternative classification approaches and systems that address particular needs of Federal agencies. It is intended to facilitate an orderly development of the NVC and collaboration with international vegetation classification activities.

This Standard applies only to vegetation documented for a specific location and time, and the NVC includes only existing vegetation types. This Standards applies to vegetation classification efforts in the United States and its Trust Territories. Specific time need not be the present, that is, historical data may be included.

Lastly, this Standard establishes minimum metadata requirements to ensure consistent reporting on the status of our Nation's vegetation resources. Both the NVC and the metadata requirements may be used nationally to link local level vegetation inventory and map efforts.
