Grand County Noxious Weed Guide - web version
Grand County Noxious Weed Guide - printable version
The Middle Park Conservation District, in partnership with Grand County Natural Resources, recently produced a Grand County Noxious Weed Guide that is specific to the Noxious weed species found in Grand County and methods for control as well as information about prevention, re-seeding, and calibrating your sprayer for proper herbicide application.
There are printer instructions in order to get the proper printout or hard copies are available at our office; NW Ranch Supply in Kremmling; the Conservation District office in Kremmling; and a few other local businesses around Grand County.
Grand County Division of Natural Resources identifies and manages State listed Noxious weeds on all County Rights-of-Way, County properties and we partner with local offices of the USFS and BLM for invasive species control as required by State law. We do not work on private property or private roads. The term, "Noxious," is a legal term and the Colorado Noxious Weed Advisory Committee assists the Colorado Department of Agriculture in determining if a non-native plant is invasive enough in CO to warrant listing for control. For more information about this committee: CO Noxious Weed Advisory Committee.
Noxious weeds are a direct and growing threat to the native environment of Grand County and the west. They threaten the very reasons we live, work, and recreate in Colorado and all Colorado land owners are responsible for controlling noxious weeds on their property. Noxious weeds are non-native plant species that have been introduced into an environment with few, if any, natural biological controls, giving them a distinct competitive advantage in dominating and crowding out native plant species, altering plant diversity and ecosystem integrity. They are aggressive, spread rapidly, possess the ability to reproduce profusely, and resist control. Pollinators are pushed to pollinating more of the non-native species instead of the native species', furthering their ability to displace native flora and negatively affect wildlife habitat and native ecosystems.
Establishment & Control
Noxious weeds become established in soils disturbed by a variety of activities such as construction, motorized vehicles, road maintenance, recreation, improper livestock grazing, and natural disturbances such as fire. Noxious weed seeds are transported to new sites in numerous ways such as wind, water, tires, people, as well as on or in wild and domestic animals.
Grand County Division of Natural Resources (DNR) operates under a directive from the Colorado Department of Agriculture to control and reduce the spread of noxious weeds in Grand County. This includes all county owned property, road rights of way, and public lands. Grand County DNR is also focused on providing information and assistance to private land owners to help control the spread of noxious weeds.
