2 <br />GENERAL MANAGEMENT PHILOSOPHY <br />Weed control is part of the overall site management and revegetation program. This <br />weed management plan will work to complement that revegetation plan. Our focus is <br />not simply to control weeds, but to remove weeds in order that desirable plants <br />(typically native grasses) can succeed. Preventative programs will occur in successive <br />years to insure that desired plants continue to thrive without competitive pressure <br />from weed species, whether designated as noxious or undesirable. We will implement <br />preventative programs, for the life of the permit, to eradicate species currently present <br />on the site and to keep the site free of species that are not yet established but which <br />are known to be pests elsewhere in the area. We will set priorities for the control <br />and /or elimination of weeds according to their actual and potential impacts on native <br />species and communities. <br />We will use an adaptive management strategy, as follows. <br />1). Establish the goals for the site. <br />2). Identify species that block us from reaching these goals and assign priorities based <br />on the severity of their impacts. <br />3). Consider methods for controlling them or otherwise diminishing their impacts and, <br />if necessary, re -order priorities based on likely impacts on target and non - target <br />species. <br />4). Develop weed control plans based on this information. <br />5). Implement the plan and monitor results. <br />6). Evaluate the effectiveness of our methods in light of the site goals, and use this <br />information to modify and improve control priorities, methods and plans. <br />7). Re- evaluate the plan and make necessary adjustments to insure that goals are <br />being met. <br />We set priorities in the hope of minimizing the total, long -term workload. Therefore, <br />we act to prevent new infestations and assign highest priority to existing infestations. <br />A. SETTING PRIORITIES <br />In a general senses, weed species will be ranked for control priority based on the <br />following criteria: <br />1. Current extent of undesirable species in the area: <br />• Species currently present & expanding <br />• Species currently present and static <br />• Species not in the immediate area, but with the potential to invade the <br />area <br />2. Potential negative impact: <br />• Species that out - compete native plant populations, excluding natives from <br />the area. <br />• Species that overtake and exclude natives following disturbances such as <br />mechanical disturbances, or that hinder restoration of natural <br />communities. <br />
