The report identifies <br /> these species as cheatgrass,white top, and musk thistle. Weld County's Weed Division inspected the site following <br /> the issuance of the inspection report. The County's inspector failed to find evidence of white top or musk thistle but <br /> did find a small area of Dalmatian toadflax, a small area of field bindweed, and a small patch of Canada thistle. <br /> Noxious weeds on the site will be controlled by Weld County. <br /> In order to control the field bindweed, Dalmatian toadflax, and Canada thistle, Tordon at 32 oz. /ac with an MSO <br /> surfactant at 32 oz./100 gallons will be used to treat these species in September or October of 2016. These patches <br /> will be treated by hand gun work to minimize any impact to surrounding plant species. In May or June of 2017, a <br /> spring inspection will be conducted to determine if any other treatments are needed. <br /> In order to control the cheatgrass, Esplanade at 5 oz. /acre in July/early August as a pre-emergent treatment. <br /> Treatments will be made using both broadcast spray on the large patches and handgun treatments of the small <br /> patches. Esplanade has shown to provide two years' worth of control of cheatgrass whose seed longevity is fairly <br /> short. During these two years of cheatgrass suppression,the surrounding vegetation on the sites in the research plots <br /> has filled in to out compete the cheatgrass. With as much other vegetation that is in the area, it is believed that this <br /> will be the similar case at Lehr. A spring inspection in February/March of 2017 (as soon as snow load is gone and <br /> the site is accessible) will be conducted to determine if any other treatments are needed before the native plants <br /> become active. Weld County applied the first treatment of Esplanade during the last week of July. <br /> It should be noted that cheatgrass is a List C noxious weed in the State of Colorado. The control of List C noxious <br /> weeds is left up to individual jurisdictions in the State of Colorado. As such, the jurisdiction of Weld County has <br /> chosen not to actively control cheatgrass. It is impossible to maintain a weed-free site in Colorado as seeds can be <br /> blown in or dispersed into a property in any number of ways. The landowner has provided a letter stating the <br /> County's attempts to control the noxious weeds on the property are satisfactory to them. <br /> Page 5 of 6 <br />
