PhotoThe National Vegetation Classification is supported by a standard that provides the basis for a process for considering, evaluating and acting on proposals. Yet, at all times, a definitive, current list of types will be available.  As revisions to hierarchy are made and new descriptions are drafted, the new information will be posted on this web site. The ESA Vegetation Panel will be managing a formal review at each level of the classification. If you are interested in participating in the review process, please contact the NVC Manager and she will guide you to the appropriate contact.


In winter 2016 the NVC for the Conterminous U.S. will be formally released.  Soon NatureServe and the ESA Vegetation Panel will be engaged in a revision and review process for the mid-levels for Alaska, Hawai’i, and Puerto Rico.


Once the initial content is formally adopted, the process for managing the NVC as a dynamic standard includes a peer review process and open access for anyone interested to submit a proposal for consideration.  Figure 1 shows the proposed data flow for managing the USNVC.


With the initial content of the hierarchy in place, the ESA Panel on Vegetation Classification is responsible for managing the peer review and publication of the Proceedings of the NVC.   When a proposal for changes to the NVC are received, the Editor-In-Chief will oversee the work of regional peer review board to conduct the peer review.   A report to the Federal Geographic Data Committee – Vegetation Subcommittee outlining the review process has been drafted and will be available on line in Spring 2016.
