Purpose and Scope
7/11/2006 FGDC Vegetation Subcommittee Briefing
Promotes the coordinated use, sharing, and dissemination of geospatial data on a national basis.
OMB Circular A-16
Purpose and Scope
7/11/2006 FGDC Vegetation Subcommittee Briefing
FGDC National Vegetation Classification Standard • Purpose
– Facilitate data-sharing
– Develop a cross-walking standard for vegetation data and information
– Builds on existing classification systems
Purpose and Scope
7/11/2006 FGDC Vegetation Subcommittee Briefing
FGDC National Vegetation Classification Standard • Scope
– Mandatory for all vegetation data gathered using federal funds.
– Cross-walking requirement applies to:• Vegetation plot data• Vegetation types (taxonomic units)• Vegetation map units

NVC Milestones• 1996-98.NVC Hierarchy completed by TNC (modified
UNESCO 1973). • 1997-98. FGDC adopts hierarchy as federal standard:
Complete set of physiognomic units (content standard); Provisional set of floristic units.
• 1998. ESA Panel is tasked to create a set of guidelines and peer review process for floristic units.
• 1998-02. Partners test the hierarchy (USFS, NatureServe) and request revisions. Canadian partners begin collaboration on a Canadian NVC.
• 2003. Hierarchy Revisions Working Group to explore revisions to upper levels.
• 2004 ESA Panel completes its guidelines; FGDC begins work on standards for floristic units, based on dynamic content standard.
• 2005 HRWG completes its draft revisions, FGDC incorporates those revisions into standards process for all units. Mexican partners begin collaboration on Mexican NVC.

NVCS Today2006
• FGDC revising floristic and physiognomic parts of NVC standard
• Federal agencies are working with the provisional NVC
• Nature Serve continues to maintain provisional set of associations and alliances:
• ESA VegBank plot database now operational.• ESA Panel developing Peer Review Process.

Revision of the FGDC Vegetation Classification
Standard• Resolve identified problems with the
physiognomic hierarchy.
• Complete the process standard for classifying alliances and associations.
• Establish all levels of the FGDC hierarchy as a “dynamic content standard.”

Implementation Needs• Databases (e.g., VegBank, Biotics, Peer
Review Tools) have been built in support of NVCS, but need further development to fill in gaps.
-prototypes of test tools are in development

-prototypes of test tools are in development
• A large backlog of vegetation types will need to be peer reviewed to begin implementation of the FGDC Standard.

• A large backlog of vegetation types will need to be peer reviewed to begin implementation of the FGDC Standard.
• Peer review and data management for the dynamic content standard will require continuity of funding (move away from an ad-hoc funded collaboration).

Dynamic Content Standard • Initiates an innovative approach to
streamline the FGDC standards process to revise the list of vegetation types.
• The classification content would be maintained by an authorized body with oversight from a national peer review board.
• Requires databases for vegetation types, plot data, and peer review tracking.– Prototypes have been developed by Nature Serve
and the ESA Vegetation Classification Panel.
Current Status / Timeline
7/11/2006 FGDC Vegetation Subcommittee Briefing
Changes to the FGDC Hierarchy
• Move Natural vs Cultural vegetation distinction to top of hierarchy.
• Reduce and revise physiognomic levels.
• Add new mid floristic levels that reflect broad phyto-geographic affinities.
