  • Taxonomic and Community Classification Resources and StandardsRobert K. PeetUniversity of North Carolina at Chapel Hill

  • Beware of dangerously obsolete standards A.E. Radford, C.R.Bell. H.Ahles. 1968. Manual of the vascular flora of the Carolinas. J.K. Small. 1933. Manual of the southeastern flora.

    Resources for plant names

  • Why we need to use new floras and new resources New names New taxon concepts (lumps & splits) New discoveries Taxa new to science New collections & overlooked collections New data sources (Plots, Heritage lists) New determinations

  • Our preferred standard! Alan S.Weakley. 2006 (or subsequent eds). Flora of the Carolinas,Virginia, Georgia, and surrounding areas.

    Resources for plant names

  • Other modern standards: USDA Plants database Flora of North America

    Resources for plant names

  • Data integration requires unambiguous identification of organisms.Taxonomic names are ambiguous. Taxonomic concepts should be represented by a name and a reference.Single largest impediment to large-scale synthesis in ecology is the failure to document taxonomic concepts.

    Species concepts & data

  • Abies lasiocarpaAbies bifoliaAbies lasiocarpasec. Littlesec. USDA PLANTSsec. Flora North AmericaThree concepts of subalpine firSplitting one species into two illustrates the ambiguity often associated with scientific names.

  • USDA Plants & ITISAbies lasiocarpa var. lasiocarpavar. arizonicaWhat are the fir trees of the West?

  • Flora North AmericaAbies lasiocarpa Abies bifoliaWhat is Abies lasiocarpa?Partnership with USDA plants to provide plant concepts for data integration

  • Which species occur with Andropogon glomeratus?Record dataFind dataMerge data

  • Taxonomic headaches The Andropogon virginicus complex in Carolina has between 1 and 9 taxa, with 17 different concepts variously applied by 8 important authors.

  • The challenge: Few large-scale compilations of concepts and their relationships are available.The good news: Multiple organizations are developing tools for concept use and integration. The greatest progress has been made here in the Southeast

  • Toward a new AtlasCarya carolinae-septentrionalis, Radford et al. 1968How to integrate new sources of data??

  • Add dynamic access to NCU collectionCarya carolinae-septentrionalisNCURAB

  • Carya carolinae-septentrionalisNCURABUSDACVSAdd USDA PLANTS records & CVS vegetation plot data

  • But wait !!There is a concept issueAccording to Radford 1968, USDA PLANTS v 4.0, & Weakley 2006Carya carolinae-septentrionalisCarya ovataAccording to Stone 1997 in Flora of North America.Carya ovata var australisCarya ovata var. ovata

  • Carya carolinae-septentrionalisSome nominal occurrences might or might not represent the taxon

  • Community types with the concept

  • Resources for community compositionCarolina Vegetation Survey website Mike Schafale & Alan Weakley. 1990. Classification of the natural communities of North Carolina. Third approximation. U.S. National Vegetation Classification (NVC; see below)
