~ ~ Re~ei~~d <br />Valco Inc.- Gunnison Concrete Division <br />Rozman Pit, Crested Butte <br />Weed Management Plan <br />Objective: <br />Sf P 2 g ?001 <br />0 <br />n c ~9oe a & Gep °9Y <br />The objective of this plan is to facilitate the implementation of a <br />noxious weed control program on lands affected by the Rozman Pit. This <br />plan will be for the duration of the project and an extended three year <br />period following the reclamation of the project. <br />Purpose• <br />The purpose of this plan is to provide procedures for the management of <br />the following designated noxious weeds and prevent the encroachment of <br />these weeds to adjacent properties. <br />Canada thistle Cirsium arvense <br />Oxeye daisy Chrysantheum leucanthemum <br />Scentless chamomile Matri ca ria perfora to <br />Yellow toadflax Linaria vulgaris <br />Authority: <br />Colorado Noxious Weed Act (C. R.S. 35-5. 5) <br />Management: <br />1. Valco will begin integrated management (Herbicide Control and <br />Revegetation) on the infestations of Canada thistle, oxeye daisy, <br />scentless chamomile and yellow toadflax. <br />2. After the infested areas have been treated with herbicide, they will <br />be reseeded as necessary to provide soil cover and competition for <br />noxious weeds. The seed mixture will contain species that compete <br />with noxious weeds and are compatible with the sight. <br />Treatment Schedule: <br />Due to the amount of disturbance associated with a gravel pit operation, <br />land associated with the pit will be treated with herbicides twice a <br />year as needed. Areas with bare exposed ground will be seeded with <br />desirable species to prevent soil erosion, maintain water quality, and <br />prevent the spread and/or invasion of State and/or County listed noxious <br />weeds. <br />It will be necessary to use more than one herbicide on the noxious weed <br />species present. The applicator for Valco should contact the Gunnison <br />County Weed Coordinator for chemical recormnendations. <br />It should be understood that all of the species listed above axe found <br />on adjacent properties. The Gunnison County Weed Coordinator is <br />currently working with the property owners to develop weed management <br />programs. <br />Before applying herbicides, the Val co applicator is strongly encouraged <br />to attend Private Pesticide Applicator training provided by the Gunnison <br />
