Why is weed management so important?
All homeowners must take responsibility for their property and respect the property of their neighbors. Uncontrolled, weeds will invade and conquer. Weed management is
more successful if neighbors join together to control the spread of weeds and share the common goal of protecting their property and the property of their neighbors from the negative effects of
noxious weeds. Controlling new or small infestations, planting competitive grasses and preventing bare spots from overgrazing are just a few ways we can all start battling these
What is the Town’s position on weed management?
ALL LIST A WEEDS MUST BE ERADICATED. Currently, Myrtle Spurge is the only List A noxious weed found within the Town. All other weeds, both from the State list and those locally
declared a nuisance, must, at a minimum, be mowed. Please keep in mind that mowing is not effective on low growing weeds such as Puncturevine or weeds that have aggressive root systems. Also,
different weeds have different growth cycles. For all noxious weeds it is essential to determine the growing cycle and appropriate timing for optimum management and control. Weeds should be mowed in
the spring and again as necessary. If they are not controlled before going to seed, the wind will spread these weeds throughout the Town and neighboring communities.
Noxious and Nuisance Weeds
The Colorado Noxious Weed Act states that certain noxious
weeds pose a threat to the natural resources of Colorado and that it is the duty of all persons to manage noxious weeds. These weeds affect local wildlife, invade open space, can be poisonous to
livestock and horses, irritating to human skin and dangerous for pets. In accordance with this Act, the Board of Trustees adopted a bill for an ordinance providing for the management and control of
What is a noxious weed?
The Act defines a noxious weed as an alien plant or parts of an alien plant that has been designated by rule as being noxious and meets one of the following additional criteria:
Aggressively invades or is detrimental to economic crops or native plant communities.
(b) Is poisonous.
(c) Is a carrier of detrimental insects, diseases or parasites.
direct or indirect effect of the presence of these plants is detrimental to the environmentally sound management of natural, open space or agricultural ecosystems.
How are the weeds categorized?
The State of Colorado, through the Commissioner of the Colorado Department of Agriculture (CDA), has declared the noxious weed list for the State. The list is divided into 3
List A: Rare noxious weeds
that are subject to eradication wherever detected statewide in order to protect neighboring lands and the state as a whole.
List B: Noxious weed species with discrete statewide distributions that are subject to eradication, containment or suppression in portions of the State designated by the Commissioner in order to stop
the continued spread of these species.
List C: Widespread and well-established noxious weed species for which control is recommended but not required by the State, although local governing bodies may require management. The Town of
Foxfield has opted to require control of weeds on List C.
How are noxious and nuisance weeds
Through an Integrated Management Plan which is a process by which one selects and applies a combination of management techniques that, together, will control a particular weed species or infestation
efficiently and effectively, with minimal adverse impacts to non-target organisms.
What are the different management strategies?
Management strategies include any activity that prevents a plant from establishing, reproducing or dispersing itself and include prevention, eradication and control methods of containment and or
Prevention: The first line of defense
to keep weeds from occurring or increasing. It includes using measures that will prevent the introduction or establishment of noxious weeds into areas not currently infested. This is the most
practical and cost effective means of weed management.
Eradication: the removal of weeds from an area so they will not recur unless reintroduced. ALL LIST A
WEEDS MUST BE ERADICATED.
Control (containment and suppression): Control reduces a weed population to a level where you can enjoy using the land. There are four control methods:
- Biological: The use of an organism to disrupt the growth of noxious weeds. Grazing is effective on some species.
- Cultural: Management practices which favor the growth
of desirable plants over noxious weeds such as maintaining healthy pastures and preventing bare spots by seeding areas with competitive grasses.
- Mechanical: Methods that physically disrupt plant
- Herbicidal: the use of herbicides
or plant growth regulators to
disrupt the growth of noxious
Combining control methods and persistent management is critical to control both noxious and nuisance weeds.
