Appendix A Key to the National Vegetation Classification (NVC) Associations which occur, or potentially occur, at Little River Canyon National Preserve NatureServe April 2009 Associations which are documented by NatureServe from Little River Canyon are in bold type. Those which are potential, but undocumented for any of the plots in this project, are in normal type. Associations highlighted in yellow are vegetation map units used by UGA – CRMS. Those associations which were not mapped, are noted in bold before the name. For each association, the common name is given, with the Element Code in brackets [CEGL00####]. 1. Communities in river or on floodplain of river or creek tributaries .......................................................................... 2 1. Upland communities or wetland communities isolated from river or creek tributaries (such as depression ponds) ....................................................................................................................................................... 13 2. Shrublands, herbaceous, or sparse herbaceous communities .................................................................................. 3 2. Forests or woodlands, stands dominated by trees .................................................................................................... 7 3. Aquatic community regularly inundated, becoming dry only during extreme drought; often dominated by Justicia americana and frequently contains the rare Kral’s water-plantain (Sagittaria secundifolia) as a secondary species ............................................................................................................................................................ ..................................................... (This association not mapped) Water-Willow Rocky Bar and Shore [CEGL004286] 3. Community occasionally inundated by water but is usually above water’s edge ..................................................... 4 4. Fern-dominated community primarily limited as riverside occurrences that are patchy and very small(This association not mapped) Cumberland Royal Fern Seep [CEGL008404] 4. Shrub-dominated community ................................................................................................................................... 5 5. Dense exotic shrub cover along creeks dominated by Ligustrum sinense .................................................................. ................................................................................... (This association not mapped) Privet Shrubland [CEGL003807] 5. Sparse to dense shrub cover not dominated by Ligustrum sinense, but comprised of various native species ........................................................................................................................................................................... 6 NatureServe LIRI - AA JUNE 2010 17
