<br />United Companies <br />Weed Management Program <br />Gunnison and Crested Butte Area <br />x.01; vec/ <br />NOV2O <br />ouran?o 09 <br />omi- <br />on of om, <br />., g <br />' <br />84r?z 14 <br />'W -400 <br />Weed control is an important aspect of United Companies facility maintenance and we are <br />committed to controlling noxious weeds. According to State law (CRS 35-5.5, the Colorado Weed <br />Management Act), noxious weeds must be managed. Integrated Weed Management is a strategy that <br />has been suggested as the structure for control programs. Elements of this approach include: <br />-:Preventing the encroachment of noxious weed species into un-infested areas <br />-.Detecting and eradicating new weed species <br />-Containing large-scale infestations <br />-Controlling large-scale infestations using an integrated approach <br />-Revegetation <br />United utilizes active measures to control noxious weed species. This plan applies to the following <br />United locations in Gunnison and Crested Butte: <br />Seahorse Ranch West Gravel Pit - DRMS Permit No. M-2001-113 <br />Gunnison West Ready Mix Pit - DRMS Permit No. M-1977-023 <br />Gunnison East Vader Pit - DRMS Permit No. M-1978-287 <br />Rozman Pit- DRMS Permit No. M-1981-014 <br />The noxious forb species observed on the properties include mayweed and scentless chamomile and <br />canada thistle. It is also expected to find a few small populations of oxeye daisy and yellow toadflax <br />at the Crested Butte pit. The percent cover of these species are light to moderate in density with a few <br />exceptions on the dense side. <br />Many of the species in this area are difficult to control and there are very small windows for proper <br />treatment. United will be proactive in weed management thus resulting in better control with longer <br />lasting effects. <br />Proposed treatment Schedule/ methods for weeds: <br />United will utilize a competent and qualified weed control specialist who will treat noxious weeds <br />with appropriate herbicides in three stages during the growing season. The first treatment will target <br />the chamomile complex, and canada thistle as soon as the plants begin to grow about mid to late <br />May. The mid summer treatment (late June to early July) will concentrate on any newly emerging <br />chamomile, canada thistle, and oxeye daisy. The final treatment will occur September to October <br />which will concentrate on all species but the emphasis will be on the creeping perennials yellow <br />toadflax and canada thistle. The herbicides proposed include the use of aquatic approved 2,4-D,
