ALBERT FREI & SONS, INC.. PAGE 2 AFS-BENNETT PIT - WEED CONTROL PLAN JANUARY 3 1 , 20 1 9 The plan follows the adaptive management approach: • First,weed species are identified through inventory of the property and by gather- ing 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 in the spring or fall as recommended by the CSU Cooper- ative Extension local office. • Seventh, the results of management actions are monitored and evaluated in light of weed management objectives for the management area. • Finally, this information is used to modify and improve weed management objectives, control priorities, and IWM plans, thereby starting the cycle again. The premise behind a weed management plan is that a structured, logical approach to weed management, based on the best available information, is cheaper and more effec- tive than an ad-hoc approach where one deals with weed problems as they arise. 3.
