Noxious Weed Management Enforcement Policy
Sec. 15-1-10. Title.
This policy shall be known, and referred to as, the "Weld County Noxious Weed Management
Enforcement Policy", and shall be in effect throughout the unincorporated areas of Weld County.
Sec. 15-1-20. Purpose of Policy.
The Colorado Noxious Weed Act,Section 35-5.5-101,et seq.,C.R.S., (hereinafter"the Act")states
that certain noxious weeds pose a threat to the continued economic and environmental value of the
land in Colorado and that they must be managed by all landowners in the State. The Act states that
local governments (cities and counties) are directed to take the necessary steps to manage the
noxious weeds in their respective jurisdictions. As a result, Weld County established a Noxious
Weed ManagementAdvisory Board and this Weld County Noxious Weed Management Enforcement
Policy.

optimum fertility and plant moisture status in an area, planting at optimum
density and spatial arrangement in an area,and planting species most suited
to an area.

bank is exhausted
(b) Containment: Maintaining an intensively managed buffer zone that separates
infested regions,where suppression activities prevail,from largely uninfested
regions, where eradication activities prevail.

desirable plant communities on lands of significant environmental or
