MADISON, Wisconsin (AP) — They slink through the woods in camouflage and face paint, armed with tire irons, screwdrivers and hoes. They're the new breed of U.S. ginseng diggers, hoping to feed rising Asian demand for the increasingly rare — and expensive — plant's roots.
Police say more diggers are pushing into the backcountry in search of wild ginseng, ripping up even the smallest plants and ignoring property lines.
The price of wild ginseng roots has climbed. Now domestic buyers pay $500 to $600 per pound (0.45 kilogram) compared with about $50 per pound of cultivated roots.
"It's lucrative to spend a day in the woods and walk out with $500 of ginseng in a bag when you don't have a job," said Wisconsin conservation warden Ed McCann. "Every one of these plants is like looking at a $5 or $10 bill."
Property owners are enraged, and biologists worried about the slow-growing plant's long-term survival.
"We're not finding big, healthy populations. It was there, and a lot of it has been taken," said Nora Murdock, an ecologist with the National Park Service. "It's like taking bricks out of a building. You might not feel the first brick ... but sooner or later, you're going to pull out too many."
Ginseng, a long-stemmed plant with five leaves and distinctive red berries, long has been coveted in many Asian cultures because the plant's gnarly, multipronged root is believed to have medicinal properties that help improve everything from memory to erectile dysfunction. The wild roots are believed to be more potent than cultivated roots.
The plant takes years to mature, and it has been harvested to the edge of extinction in China. Ginseng buyers have turned to North America, where the plant can be found from northeastern Canada through the eastern U.S.
Conscious of the harvesting pressure, the Convention of International Trade of Endangered Species of Wild Fauna and Flora imposed restrictions on exports in 1975. Under those terms, states certify ginseng has been harvested legally, and exporters must obtain a federal permit. Most states have restricted ginseng harvest to a few months in the fall and require diggers to obtain permits. It's illegal to harvest ginseng from any national park.
Poachers dig up immature roots, ensuring the plants won't reproduce and feeding a cycle of dwindling populations and rising prices.
It's difficult to get a clear picture of the extent of poaching in the U.S. Violation statistics are spread across layers of state and federal jurisdictions, but law enforcement officials and biologists across the eastern half of the country told The Associated Press they believe it's on the rise.
A team of West Virginia University researchers counted 30 ginseng populations across New York, Pennsylvania, Maryland, Indiana, Kentucky, Virginia and West Virginia between 1998 and 2009. The team reported that of the 368 plants they discovered had been harvested, only five were taken legally.
In Wisconsin, the leading U.S. producer of commercially grown ginseng, wildlife officials say violations such as harvesting wild ginseng without a permit or harvesting out of season tripled from 12 in 2007 to 36 last year.
Ohio wildlife authorities made 100 arrests between 2008 and last year for various ginseng violations ranging from digging without permission to digging or buying out of season.
"It's very difficult to catch a poacher," said U.S. Forest Service botanist Gary Kauffman. "You could put everything in a backpack and your hands are clean, nobody really knows what you're doing."
A grand jury in southeastern Ohio charged 78-year-old Joseph Kutter with killing a man whom Kutter claimed had trespassed onto his property to poach ginseng. According to court documents, Kutter shot Bobby Jo Grubbs with an assault rifle in May and hid his body in a mulch pile. Kutter's attorneys didn't return messages seeking comment.
Sara Souther, a University of Wisconsin-Madison botanist who worked on the West Virginia University ginseng team, said multiple times she has encountered poachers trying to harvest the plant.
"These are intimidating people," Souther said. "You can tell these men are not hiking. If you're out there and witness an illegal act, you don't know what people will do."
