Noxious Weeds
Noxious weeds are invasive plant species that can be detrimental to the local ecosystem. Noxious weeds can out-compete native plants, decreasing native vegetation important to animals and insects. Some noxious weeds can be poisonous, and sometimes deadly, to livestock and household pets.

Eliminate Noxious Weeds
Many weeds are slow to establish, but will grow and expand rapidly once they have taken hold. Removing noxious weeds from your property helps prevent their spread to other properties in Cortez and agricultural land outside of the City limits. The early detection and removal of noxious weeds is important to inhibiting growth.
How to Dispose of Noxious Weeds:
- Pull the weed out by the root, if possible. Hand pulling or digging out the roots is most effective when the soil is moist, either in late spring or after a deep rain.
- If the plant is blooming, bag it to reduce the spread of seeds.
- Throw weeds away in the trash. Do not add weeds to a burn pile or compost.
- Mowing or cutting back weeds does not reduce the overall population of noxious weeds, although it can help control the overall spread.
