7 <br /> Integrated Noxious Weed Control Plan: The development of this plan is accordance with Section 3.1.10 <br /> (6) of the Mineral Rule and Regulations of the Colorado Mined Land Reclamation Board for the <br /> Extraction of Construction Materials, which states: Methods of weed control shall be employed for all <br /> prohibited noxious weed species,and whenever invasion of a reclaimed area by other weed species <br /> seriously threatens the continued development of the desired vegetation.Weed control methods <br /> shall also be used whenever the inhabitation of the reclaimed area by weeds threaten to further <br /> spread of serious weed pests to nearby areas. <br /> This Integrated Noxious Weed Management Plan is for the control of noxious weed species within the <br /> Two Rivers gravel permit boundary. The plan identifies existing noxious weed on the property and <br /> potential weeds in the vicinity of the pit that may invade the site. Appropriate weed control actions <br /> shall be implemented whenever noxious weed species are observed on the property per the attached <br /> noxious weed fact sheets. <br /> 1. Weed control must be applied and evaluated over an extended period of time to be successful. <br /> 2. The basic steps of Weed Control include identification of weed species, locating the weed <br /> problem, development of control and prevention strategies, implementation of those strategies, <br /> and ongoing monitoring to assess the effectiveness of the efforts. <br /> 3. To prevent or minimize the infestation and spread of noxious weeds, bi-annual inspections of <br /> the pit area will evaluate presence or absence, degree of invasion, and the response to previous <br /> treatments in the spring and fall of each year. <br /> 4. Specific treatment methods and time tables are identified in the attached weed summaries. <br /> Plans may be modified based in new invasions of weed based on the species of concern, <br /> location and extent of the infestation, and other pertinent factors. <br /> WEED MANAGEMENT GOALS AND PRIORITIES:This management plan focuses on the control of <br /> targeted noxious weed species listed below. <br /> The goal is to implement this weed control plan. The best management practice for this site is to <br /> contain the current infestations of salt cedar/tamarisk and work towards its elimination. <br /> Following is a general description of the basic types of weed management. Also refer to the specific <br /> noxious weed guidelines provided by the Turkey Creek Conservation District and Colorado Department <br /> of Agriculture in the attached noxious weed fact sheets. It is very important to get control of these <br /> invasive species on a local level. <br /> • Elimination or eradication is the complete removal of a weed infestation. It is the <br /> implementation of a short-term but intensive control effort to completely purge a targeted <br /> weed infestation permanently from an area (unless reintroduced). Elimination is desirable and <br /> possible for small weed patches, but not always for larger ones. (Important note: if eradication <br /> creates an open environment, a weed problem may be cured simply to create another one; <br /> therefore, it is essential to revegetate the ground to prevent another infestation.) <br /> • Containment prevents weed encroachment onto non-infested areas. It is the creation of <br /> confining perimeters around the infestation.This is achieved by eradicating plants on the <br /> exterior of the infestation's designated perimeter and those along roads, streams and trails that <br /> may help spread the infestation beyond the perimeter. <br /> • Suppression reduces weed density and area. It is the use of a wide variety of weed management <br /> techniques that reduce the density and severity of infestations within the boundaries of <br /> containment perimeters.This is done to mitigate harm to agriculture,environment and other <br /> valuable land caused by widespread populations of noxious weeds. <br />
