Federal, state and county officers spent about a week cutting down marijuana gardens across the Sequoia National Forest above Porterville in an effort named Operation LOCCUST.[1][2][3] By 7 August 2008 they had destroyed more than 420,000 plants at 83 grow sites in the Sugar Loaf and Blue Ridge areas, a haul officials valued at more than $1 billion on the street.[1][2] Tulare County Sheriff Bill Wittman called it the largest and most sophisticated growing operation authorities had seen in recent years.[2]

36 arrested, weapons and contraband seized

Officers arrested 36 people on suspicion of offences including cultivation of marijuana, possession for sale, firearms offences and conspiracy.[2][3] They seized 27 weapons along with $6,900 in cash, three vehicles, eight ounces of cocaine and two and a half pounds of methamphetamine found at the sites.[3] The suspects were booked into custody while the investigation continued.[3]

Officials attributed the grows to a Mexican drug cartel that chose the remote forest to cultivate and live, leaving camps with tents, food and poached wildlife.[1][2] Crews also hauled out miles of irrigation pipe, tonnes of rubbish, fertiliser and pesticides that officials said threatened wildlife and the water table.[2][3] The operation drew national attention: drug czar John Walters joined the sheriff and the US attorney at a Visalia news conference on 6 August.[3]
