QMy neighbor has very tall weeds. Can I report this to the Weed District?

ALarimer County has NO HEIGHT ORDINANCE. Cities DO HAVE HEIGHT ORDINANCES. The Weed District has jurisdiction only over county listed noxious weeds. The Weed District can only help if 1). One of the nine noxious weeds is present AND 2). The property is in Larimer County and DOES NOT fall in any city's limits. See pictures and descriptions of the noxious weeds. If both conditions apply, call us at 970-498-5768 to report it. Note: The Weed District makes every effort to keep all reports confidential! Unfortunately, we cannot enforce on anything other then noxious weeds. If no noxious weeds are present, talk to your neighbor! Ask them to mow their weeds. If you want to know the name of your neighbor, look at the Assessor's website for more information.

QWhat is a noxious weed?

AThe term "noxious" has a legal connotation with the Colorado Department of Agriculture - non-native and invasive (can out-compete and exclude other types of vegetation). Most noxious weed species in Colorado originated in Europe and/or Asia, and were unintentionally introduced into the United States as a contaminant in crop seed or on farm machinery. Some were intentionally introduced as ornamental plants, forage, or plants used as wind breaks or for soil stabilization. These non-native plants have proliferated or have the potential to proliferate in Colorado due to:

  • The country or region of origin has a climate, soil type, and/or elevation similar to that of Colorado
  • Introduced species lack the natural checks that kept them in balance in their native range such as:
    • Competition from plants they co-evolved with
    • Browsing by large native herbivores they co-evolved with (Colorado's native herbivores such as deer and elk seldom feed on weedy plants)
    • Insect predation
    • Soil nematodes, diseases, and other factors

QAre these the only weeds we need to be concerned about?

ANo. There are many more weeds that degrade our environment. However, the Colorado Noxious Weed Control Act mandates control and enforcement only on designated noxious weed species. Look at our troublesome weed list for other weeds and management suggestions.

QCan employees of the Weed District enter upon private land without first getting the landowner's permission?

AYes, but only to perform weed management if the landowner has refused to do so after due notice. Per the Colorado Noxious Weed Control Act, a Right To Enter Upon Lands form is signed by one of the county commissioners, thus authorizing the Weed District to enter onto the property to perform weed management. Landowners will then be assessed a fee for the services provided. This is always a last resort. The Weed District makes every attempt to notify and work with the landowner first.
