The Washington State Patrol located a decreased number of large, outdoor marijuana grows on public land during the 2013 summer growing season.
NBCRightNow.com - The Washington State Patrol found fewer large, outdoor marijuana grows on public land during the 2013 summer growing season.
According to Troopers, the continued decline over the past nine years is because of aggressive eradication efforts and keeping the pressure on drug traffickers that misuse public lands to grow large quantities of marijuana.
Marijuana eradication teams eliminated 39,113 plants this year. That's down from 216,010 in 2012, and from a high of 609,133 in 2009.
Eradication is done by identifying and locating the illegal grow sites, and because they are on public land, search warrants are not needed.
Washington State Patrol says outdoor grow sites targeted for eradication not only produce marijuana, but are dangerous and environmental disasters. Some growers have been known to booby trap their grow sites.
Troopers also saw a decrease in "corn grows," where growers sneak onto a farmer's land and plant marijuana in the center of what would otherwise be a vast cornfield. Growers then harvest their illegal crop prior to the landowner harvesting their legitimate corn crop.
