Chavers Mining Resource Integrated Noxious Weed Management Plan January 2024 Page 2 1.2 WEED MANAGEMENT PRIORITIES AND GOALS The priorities of this weed management plan are to: 1) contain current noxious weed infestations; 2)suppress and/or eliminate noxious weed species present; and 3)prevent potential invasive weed species in Weld County from infesting the Site. General descriptions of these basic weed management goals for the Site are below: ■ Elimination/Eradication: Elimination(or eradication)is the complete removal of a weed infestation. It is the implementation of a short-term but intensive control effort to completely purge a targeted weed infestation permanently from an area(unless reintroduced). Elimination is desirable and possible for small weed patches, but not always for larger ones. (Important note: if eradication creates an open environment, a weed problem may be cured simply to create another one; therefore, it is essential to revegetate the ground to prevent another infestation). ■ Containment: Containment prevents weed encroachment onto non-infested areas. It is the creation and enforcement of confining perimeters around the infestation. This is achieved by eradicating plants on the exterior of the infestation's designated perimeter and those along vector corridors(such as roads, streams,trails)that may help spread the infestation beyond the perimeter. ■ Suppression: Suppression reduces weed density and area. It is the use of a wide variety of weed management techniques that reduce the density and severity of infestations within the boundaries of containment perimeters. This is done to mitigate the harm to agriculture,the environment, and other values caused by widespread and well-established populations of noxious weeds. 1.3 LOCAL AGENCY EVALUATION AND CONSULTATION ASCI contacted the Weld County Public Works Department - Weed Management Division for assistance in preparing this weed management plan. A site visit to identify the types, locations, and extents of noxious weeds present at the Site was conducted with Weed Management Division Supervisor, Ms. Tina Booton, on December 4, 2023. Information regarding the identification and management strategy for noxious weeds obtained from the Weed Management Division is present throughout this plan.
