3. SPECIFIC CONTROL PLANS FOR HIGH PRIORITY WEED SPECIES <br />Weed: Russian knapweed (Centaurea repens), and related species--Spotted or <br />diffuse knapweed Priority: 1 <br />A. Current distribution: Existing infestations of Russian knapweed are known to be present <br />on the project site. This weed is notorious for infesting gravel pits and seed then being <br />spread with the contaminated gravel. Determination of extent of current infestation will <br />be made at initial weed survey used to develop baseline data. <br />B. Goal: To eradicate the existing populations and prevent spread to non-infested <br />locations in, or within, the permit area. <br />C. Management plans: Utilize herbicide applications as warranted by severity of infestation. <br />D. Evaluation: Assess population changes through annual inventory. <br />Weed: Canada thistle (Cirsium arvense) Priority: 1 <br />A. Current distribution: One small patch is located on the property. <br />B. Goal: To eradicate current population and prevent spread to non-infested locations <br />within the project area. <br />C. Management plans: Reduce any population through herbicide application. <br />D. Evaluation: Assess population changes through annual inventory. <br />Weed: Tamarisk (Tamarix ramosissima) Priority: 1 <br />A. Current distribution: Known infestations are present in the southwestern corner of the <br />site. This, and other infestations, will be identified at initial weed survey used to <br />develop baseline data. <br />B. Goal: To eliminate existing populations, and prevent establishment of new infestations. <br />C. Management plans: Utilize herbicide applications as warranted by severity of infestation. <br />D. Evaluation: Assess population changes through annual inventory. <br />Weed: Field bindweed (Convo/vu/us arvensis) Priority: 1 <br />A. Current distribution: Currently there is a known population on previously farmed areas <br />of the project site. Extent will be determined at initial weed survey used to develop <br />baseline data. <br />B. Goal: To control existing populations and prevent spread onto other areas of the project <br />site. <br />C. Management plans: Utilize herbicide applications as warranted by severity of infestation. <br />D. Evaluation: Assess population changes through annual inventory. <br />Weed: Kochia (Kochia scoparia) Priority: 2 <br />A. Current distribution: Kochia is on the Otero County noxious weed list. Currently there is <br />a known population on previous farmed areas of the project site. Extent will be <br />determined at initial weed survey used to develop baseline data. <br />B. Goal: To control existing populations and prevent spread onto other areas of the project <br />site. <br />C. Management plans: Utilize herbicide applications as warranted by severity of infestation. <br />D. Evaluation: Assess population changes through annual inventory. <br />7 <br />All Rite Paving & Redi-Mix, Inc. Site Weed Management Plan June 20, 2008
