Indicators of outdoor grow operations include unusual amounts of traffic; use of camping equipment or recreational vehicles on wooded property with no evidence of recreational activities; large amounts of PVC piping, irrigation hoses or plastic planters located in heavily wooded areas; use of fertilizer in remote areas and patrolled or guarded woods or swamps. 

To report a suspected marijuana grow site, call 1-800-235-HEMP (4367).  Callers can remain anonymous.  Individuals should not attempt to take action themselves, but instead report the site to law enforcement as soon as possible.

Last year, over 40,000 plants were found growing outdoors including over 4,000 plants found in Gladwin County after hunters alerted law enforcement in the area.  This is an increase from the 23,198 plants located outdoors in 2007.
