Federal and local law enforcement officials are citing increased environmental degradation as a primary reason for an imminent crackdown on large-scale marijuana grow operations. But when it comes to the full scope of the damage, it's difficult to get more than anecdotal examples of diverted streams, unpermitted soil grading, the clear cutting of trees, heavy fertilizer and pesticide usage and stories about tons -- literally tons -- of garbage left in some of the state's most pristine public lands. The only peer reviewed scientific study that begins to quantify the impacts of large-scale, illicit pot grows was released earlier this summer by UC Davis researchers. It concludes that the heavy use of high-powered rodenticides at outdoor marijuana grows is likely a leading cause of death for the Pacific fisher, a reclusive weasel-like creature that is currently a candidate for federal protection under the endangered species act. Lauding the study as a "game changer," many officials said it underscores the need to make sure illegal grow sites are properly cleaned up and to find funding for studies on other potential impacts associated with large-scale marijuana cultivation. "The truth of the matter is you don't have to have the flu to know it's bad -- they can do 400 studies, and I know it's bad," said North Coast Congressman Mike Thompson in a recent phone interview with the Times-Standard. "But, anything at all that can be done to quantify this -- to show exactly how bad it is -- I think we need to do." Several officials -- including Thompson -- said they believe increased scientific data quantifying the environmental damage caused by large-scale illegal marijuana grows will loosen federal purse strings, leading to a much needed increase in federal funding to help clean up some of the damage. When police raid a grow site, it's often the marijuana plants that garner the attention -- with headlines boldly stating how many thousands of plants were pulled from a remote section of a national or state park. But, it's the other items found at the grow sites that may actually pose a larger danger to the public. Humboldt County Sheriff's Sgt. Wayne Hanson said it's not uncommon for investigators to find complex mazes of plastic irrigation lines and large containers of high-powered pesticides, fertilizers and rodenticides. Then, he said, there's the trash -- often mounds of soda cans and other debris -- and literally piles of human feces in holes dug into the ground and used as makeshift outhouses. Traditionally, these things get left behind by law enforcement, he said. "We don't have the time nor the resources to switch modes after we eradicate the marijuana into reforesting and cleaning up," he said. "We remove the marijuana and look for suspects and clues as to who's doing it, but we do not clean up the sites." Instead, Hanson said, law enforcement will call state parks, fish and game or the bureau of land management to notify them of the eradication operation so that, if they choose, they can follow up with a cleanup effort. The problem, most concede, is that rarely happens. The other agencies are underfunded and overworked, and simply don't have the resources to conduct a large-scale cleanup effort of the grow sites, which are often only accessible by helicopter or by hiking through miles of dense forest. In some cases, this leaves the sites -- still complete with the growing infrastructure -- as prime cultivation locations for the same organizations that planted the first crop of plants. Thompson pointed to a marijuana eradication operation in Mendocino County last summer that pulled more than 1,000 plants. Two days later, Thompson said, Mendocino County Sheriff's Department deputies were flying over the site and reported seeing some activity on the ground. When they landed, Thompson said, they were shocked at what they found. "Every hole was filled with a new plant," Thompson said. When the Humboldt County Sheriff's Office busted a 26,000 plant grow near Hoopa recently, Sheriff Mike Downey said the site had been used and busted several years earlier. But there is new push to make sure some of these sites are cleaned up, according to Tommy Lanier, head of the White House-funded National Marijuana Initiative. With California's Campaign Against Marijuana Planting program, known as CAMP, strapped due to state budget cuts, the feds are looking to fill the void. Lanier said the federal public lands and drug enforcement agencies have gotten together and formed a new program, known as the Cannabis Eradication and Reclamation Team, that will put equal focus on pulling pot plants and cleaning up after the growers who planted them. "That's a big priority for us -- to get the infrastructure out of these parks, to reduce the impacts and reclaim our watersheds," Lanier said. Downey said he's also working to partner with other local and state agencies whenever his deputies bust a grow site, trying to make sure the operation is cleaned up afterward. In the Hoopa bust, Downey said, deputies left the cut down, immature marijuana plants on site and used the helicopters to pull out trash and the grow's infrastructure. But all concede there are more grow operations out in the hills and forests than could possibly be busted, much less cleaned up and reforested, with current resources. "We're trying to have enforcement actions target the people, organizations and operations that are the most egregious," Lanier said. Randy Wagner, the special agent in charge of the Drug Enforcement Agency's Northern California operations, said his agency is making a concerted effort to work with the Environmental Protection Agency and the Department of Fish and Game when conducting marijuana eradication operations. In addition to having those agencies on board to possibly help investigate and prosecute growers for violating environmental laws, Wagner said they have the expertise to properly assess the environmental and health risks associated with the sites. "When we're on location with someone, and we see something dangerous, we're not going to leave it behind," he said. "We're not going to leave a scene unsafe for people or the environment. We'll secure the area and bring in the experts in our agencies that can deal with the cleanup." While law enforcement agencies seem to be paying increased attention to the environmental aspects of grow sites, officials say more studies are needed to bring even more resources to the table. The UC Davis researchers are already looking into the impacts rodenticides may have on species other than the fisher and on ecosystems as a whole. Lanier said he's looking to secure funding to have universities study the potential impacts of smoking marijuana that's been treated with heavy-duty pesticides and fertilizers. Thompson said he's interested in seeing data on the impact marijuana grows have on watersheds and fisheries, noting that stream diversions and heavy fertilizer usage likely contribute to low flows and heavy algae blooms. As a congressman who has secured a great deal of funding for salmon studies and restoration over the last decade, Thompson said the situation is hugely frustrating. "We're spending millions of dollars, if not billions of dollars, trying to restore our fisheries, and then these guys come along and just put all of our efforts back by light years," he said. "It's a huge, huge mess." - --- MAP posted-by: Jay Bergstrom
