  2. Piedmont brownwater rivers

  3. Alluvial plant communities of Piedmont brownwater rivers • Describe the vegetation composition and structure • Inform management decisions and future restoration projects

  4. Piedmont brownwater rivers

  5. CVS protocol • 20m X 50m plots • Nested corners in 4 intensive modules • Cover by strata • Soil samples and geomorphic position

  6. Analysis • Cluster techniques • Ordination • Indicator species analysis • Comparison of groups with current classifications • Classification of the Natural Communities of North Carolina, 3rd approximation, Schafale and Weakley • U.S. National Vegetation Classification
