Overview
12/04/07 FGDC Vegetation Subcommittee Briefing
FGDC National Vegetation Classification Standard
• Purpose and Scope
• Response to Public Review Comments
• Draft Implementation Plan
Overview
12/04/07 FGDC Vegetation Subcommittee Briefing
FGDC National Vegetation Classification Standard • Purpose
– Facilitate data-sharing among Federal agencies and partners
– A cross-walking standard for vegetation data and information (local to global)
– Does not replace classification systems used by individual agencies
Purpose and Scope
12/04/07 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
Purpose and Scope
12/04/07 FGDC Vegetation Subcommittee Briefing
FGDC National Vegetation Classification Standard -
1997• Established a physiognomic/floristic
vegetation hierarchy
• Established a content standard for the physiognomic levels– A list of vegetation types
• Initiated the development of a process standard for the floristic levels– How to define floristic vegetation types
History
12/04/07 FGDC Vegetation Subcommittee Briefing
Revision of the FGDC Vegetation Classification
Standard• Resolve identified problems with the
physiognomic hierarchy
Current Status / Timeline
12/04/07 FGDC Vegetation Subcommittee Briefing
Revision of the FGDC Vegetation Classification
Standard• Resolve identified problems with the
physiognomic hierarchy
• Complete the process standard for classifying alliances and associations
Current Status / Timeline
12/04/07 FGDC Vegetation Subcommittee Briefing
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”
Current Status / Timeline
12/04/07 FGDC Vegetation Subcommittee Briefing
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 NatureServe
and the ESA Vegetation Panel
Current Status / Timeline
12/04/07 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
Current Status / Timeline

Implementation Plan Objectives
• Facilitate & support development of standard vegetation classification
• Maintain & disseminate classification content
• Define & adopt standards for data collection & analysis
Implementation
12/04/07 FGDC Vegetation Subcommittee Briefing
Implementation Plan Objectives
• Maintain scientific credibility through peer review of proposed changes
• Facilitate inter-agency collaboration and inter-agency product consistency
Implementation
12/04/07 FGDC Vegetation Subcommittee Briefing
Core Implementation Activities
1. Maintain & disseminate current & previous versions of dynamic content of the standard
2. Maintain & disseminate supporting data that form the basis for decision on content
3. Preparation & submission of proposals for revising the standard
Implementation
12/04/07 FGDC Vegetation Subcommittee Briefing
Core Implementation Activities
4. Review and evaluate proposals for revisions of classification content
5. Disseminate results of review process & incorporate approved changes of classification standard in a public record
Implementation
12/04/07 FGDC Vegetation Subcommittee Briefing
Other Implementation Features
• Implementation will vary between natural and cultivated vegetation types
• Outreach and training materials will need to be developed
• Must provide for long-term maintenance• Must be compatible with other
international vegetation classification standards
