Bloodroot (Sanguinaria canadensis) Distribution and Supply on the Waynesville Watershed in Western North Carolina
Inventory data from nine stands of bloodroot (Sanguinaria candensis L.) on the Waynesville watershed in Western North Carolina are analyzed to determine distribution and supply of the resource. Inventory data analysis and a review of the relevant literature explore the potential of bloodroot to be harvested sustainably as a non-timber forest product. Additional qualitative analyses of several forests in North Carolina provide a context for interpreting the data collected on the Waynesville watershed and a means for comparing harvested stands with protected stands.
Sampling took place in June through August of 2007 in Western North Carolina and data analysis examines the relationships between various plant demographic and environmental variables. There is a high degree of variability between the nine stands and mean bloodroot stand densities range from 2.1 to 35.417 plants per square meter. Stand sizes vary from 5.28 to 47,400 square meters. Projections based on the data suggest that only 0.5 to 1.8 percent of the Southern Appalachian region supports bloodroot growth and comparisons between forests suggest that populations subject to harvesting face population decline.
Statistical analysis of 174 bloodroot rhizomes reveals that stem height and stem diameter are good predictors of belowground biomass. Results may be used to guide the development of sustainable harvesting regimes.
