| Abstract Detail
Ethnobotany Bradford, Caroline [1], Metzgar, Jordan [2]. Collection analysis and predictions on availability for two Southern Appalachian wildflowers (Sanguinaria canadensis and Trillium erectum). Sanguinaria canadensis (Papaveraceae), commonly known as bloodroot, and Trillium erectum (Melanthiaceae), commonly known as Red Trillium, are native North American flowering plants that have been collected for generations. The medicinal properties contained within each species have continued to generate a vast interest in collectors. These species play an integral role within traditional medicinal practices as well as having modern pharmaceutical uses. Their rising popularity makes it important to better understand current harvest rates and practices along with potential threats these species may encounter from over-collecting or changing climates. Southern Appalachian residents were surveyed to determine any trends for the availability of both species. In addition, we produced estimates of the projected effects that anthropogenic climate change will have on Sanguinaria canadensis and Trillium erectum using species distribution models. Our preliminary results show a drastic decline in both populations as a result of both mild and severe warming scenarios. These results emphasize the need for more detailed harvest data due to the serious implications of declining habitat availability for both species. Each species holds a valuable cultural and medicinal role in many communities and our research will contribute to efforts to conserve their populations.
