A map showing our 30 study populations
located in 7 states

The data for our research comes from intensively monitoring over 4,600 plants in 30 ginseng populations located in 7 states. Annually, census data on individual plant survival, size, health and reproduction is collected. Our study populations are representative of typical ginseng populations, and occur in a variety of habitats ranging from suburban woodlots to rich, old-growth forests.
