American ginseng Ginseng. HABITAT: Deep leaf litter in rich, moist deciduous woods, especially on rocky, shaded, cool slopes in sweet soil. STATUS: Rare in Canada. Threatened in the United States. Possibly extirpated in Rhode Island; endangered in Alabama, Delaware, and Mississippi; threatened in Connecticut, Illinois, Kentucky, Massachusetts, Michi- gan, New Hampshire, New York, North Carolina, Ohio, Oklahoma, South Carolina, Tennessee, Virginia, and Wisconsin; rare in Arkansas, Iowa, Louisiana, Maine, Minnesota, Nebraska, New Jersey, Pennsylvania, Ver- mont, and West Virginia. NOTES: Panax quinquefolium occurs across southern Ontario and adjacent Quebec, but it is relatively rare throughout. It grows in populations ranging from 2-3 plants up to 50-60, or rarely 200, individuals. The spe- cies is included here as rare in Ontario because of its declining population due to the commercial harvest of roots and the loss of hardwood forests. Threats to the species from international trade have led to its listing in Appendix II of the Convention on International Trade in Endangered Species (CITES) and the annual export of root from Ontario is monitored by permits issued by the Ontario Ministry of Natural Resources. American ginseng is highly valued in the Orient as a panacea and it is increasingly used in North America as an herbal medicine. Since its discovery near Montreal in 1715 there has been a flourishing trade in dry roots. In 1979-1980 export permits were issued by CITES HABITAT: Couches épaisses de feuilles mortes des forêts de feuillus touffues et humides, en particulier sur des talus rocailleux, ombragés et frais, en terrains alcalins.
