Ridgway: Spotted knapweed or herbicides on Uncompahgre River riparian areas through town?

From The Telluride Watch (Gus Jarvis):

Majority opinion in Ridgway has forbidden the use of herbicides within town limits in the battle to eradicate weeds to the point where Town Council has passed a resolution that states that no chemical herbicides may be used. The problem, according to Mabry, is that the spotted knapweed (Centaurea maculosa), a non-native species, is spreading like wildfire along the banks of the river and something needs to be done about it. Spotted knapweed is designated as a “List B” species on the Colorado Noxious Weed Act and it is required to be either eradicated, contained, ore suppressed depending on the infestation. “My biggest concern is the spotted knapweed down along the river,” Mabry declared at council’s March 17 work session, showing pictures from last summer proving the weed has a stranglehold on the riverbanks. “As you can see, it is forming a monoculture by forcing out all the native species down there. I see this as a critical problem.”
