Weed Lists and Laws

The Colorado Noxious Weed Act
 
Since 1990, the Colorado State Department of Agriculture has protected the state’s natural resources by enforcing regulations controlling noxious weeds. More recent revisions to the Colorado Noxious Weed Act, 35-5.5-101-119 C.R.S., enables County and City governments to implement management programs aimed at noxious weeds in order to reclaim infested acres and protect weed-free land. 

These changes included categorizing the State noxious weed list into three separate list, A, B, and C. 

List A plants are designated for elimination on all County, State, and Federal and Private Lands. 

List B includes plants whose continued spread should be stopped. 

List C plants are selected for recommended control methods. 

Please see our La Plata County Priority and Enforceable Weeds brochures.  They are also available at the County Weed Office.
