Hayden Gulch Terminal, Inc. * Hayden Gulch Loadout Weed Management Ptan <br />i <br />r1 <br />L_J <br /> <br />HGTI reclamation personnel aze aware of the following noxious weed species that have been <br />identified on properties adjacent to, or in the local vicinity of, the mine permit lands. If a newly <br />emerging population of a particular species is identified on the mine permit lands, the species will <br />be managed in accordance with this weed management plan. <br />Black henbane (Hyoscyamus niger) <br />Field bindweed (Convolvulus arvensis) <br />Leafy spurge (Euphoria esula) <br />Musk thistle (Carduus nutans) <br />Perennial pepperweed (Lepidium latifolium) <br />Russian-olive (Elaeagnus angustifolia) <br />Salt ceder (Tamarix chinensis) <br />Yellow toadflax (Linaria vulgaris) <br />Whitetop, Hoary Cress (Cardaria draba) <br />In addition, several invasive and highly competitive weed species not identified in the Colorado <br />Noxious Weed Act are found on HGTI controlled lands; these species wilt be managed as <br />deemed appropriate by HGTI project personnel. <br />Common cocklebur (Xanthium <br />strumarium) <br />Curly cup gum weed (Grindelia <br />squarrosa) <br />Kochia (Kochia scoparia) <br />Prickly lettuce (Lactuca serriala) <br />The following sections describe the techniques and methods that HGTI will use to control <br />noxious weed infestations on HGTI property. <br />Prevention Methods <br />1. Prevent new noxious weeds from becoming established by stopping seed production. <br />Mechanical, chemical, or biological control is necessary prior to seed set. <br />2. To the extent possible, clean and/or wash vehicles on the site to prevent accidental <br />transport of noxious weed seed or plant parts. This includes a visual inspection to check <br />for vegetative matter, and if necessary, physically remove parts (i.e., stakes, seed heads, <br />etc.) from pinch points, as well as dirt and soil from mud guards, etc. Washing <br />operations could involve using water, transported in a portable tank, to hose down an <br />extremely dirty vehicle. <br />3. Plant only certified weed-free seed. <br />4. Buy and import materials, (gravel, sand, topsoil, etc.) only from weed-free sites. <br />5. Monitor weed control efforts on an annual basis. Survey the property to detect new <br />invasive species or new establishment of existing species. The spring survey and <br />mapping will be done prior to weed control. A follow-up survey will be conducted after <br />control measures to insure good control and to determine if additional measures aze <br />needed. <br />6. If necessary, treated areas will be re-seeded to re-establish a competitive and beneficial <br />plant community.
