(CNN) — More than $1 billion worth of marijuana has been uprooted from federal lands during a two-month operation targeting illegal pot farms, federal authorities announced Tuesday.
Operation Mountain Sweep has resulted in the destruction of 578,000 marijuana plants, Benjamin B. Wagner, U.S. attorney for the Eastern District of California, said in a press release.
The operation, involving agents from the Drug Enforcement Administration, Department of Homeland Security, U.S. Forest Service, National Park Service, Bureau of Land Management and the U.S. Fish and Wildlife Service as well as local agencies, targeted growing sites on public lands in seven Western states — Arizona, California, Idaho, Nevada, Oregon, Utah and Washington.
Wagner said 14 individuals in California have been indicted on charges resulting from Operation Mountain Sweep. Authorities have shut down 96 pot farms on public lands in California since the operation began July 1, the federal authorities said. Among those pot farms were sites in national forests and parks, including Death Valley National Park.
Besides producing an illegal crop, the pot farms can do long-term damage to public lands by destroying trees and vegetation, introducing chemicals and pesticides, diverting water sources, and generating large amounts of trash.
“Those who cultivate marijuana on public lands pose a safety threat to the public and an environmental threat to the land. Many of the grow sites are controlled by drug trafficking organizations, which arm their cultivators with dangerous firearms. The poisons they spread kill wildlife and native plants and pollute watersheds,” Wagner said in the press release.
The operation will continue through the end of August, authorities said.
