COLORADO ROSE RED, INC. COLORADO ROSE RED STONE RESOURCE - WEED CONTROL PLAN MARCH 12, 2014 PAGE 2 already established on the property, according to their actual and potential impacts on the land management goals for the prop- erty, and according to the ability to control them now versus later. Actions will be taken only when careful consideration indicates leaving the weed unchecked would result in more damage than controlling it with best available methods. The plan follows the adaptive management approach: • First, weed species are identified through inventory of the property and by gathering information from other sources. • Second, land management goals and weed management objectives are established for the property. • Third, priorities are assigned to the weed species and weed patches based on the severity of their impacts, while considering the ability to control them. • Fourth, methods are considered for controlling them or otherwise diminishing their impacts and, if necessary, re -order priorities based on likely impacts on target and non - target species. • Fifth, An Integrated Weed Management (IWM) plan is developed based on this information. • Sixth, the IWM plan is implemented. • Seventh, the results of management actions are monitored and evalu- ated in light of weed management objectives for the management area. • Finally, this information is used to modify and improve weed manage- ment objectives, control priorities, and IWM plans, thereby starting the cycle again. The premise behind a weed management plan is that structured, logical approach to weed management, based on the best available information, is cheaper and more effective than an ad -hoc ap- proach where one deals with weed problems as they arise. 3.
