The plan does not <br />contemplate total weed removal on the property. Past experience shows that some initial weed <br />cover in the first year following the retopsoiling is beneficial to the reclamation effort in dry <br />range site. Weeds tend to provide shade for new grasses, are a means of holding snow on the <br />seedbed longer and protect it from wind and water erosion until the planted species have taken <br />hold. <br />During the removal of overburden, if an area of heavy seed infestation is encountered, it will be <br />buried in the slopes rather than used as a growth medium. 1 During all phases of the mining <br />operation, the area will be monitored closely every year in which the permit is active to <br />determine if there are any additional weeds invading it. Weed control will again be initiated if <br />the problem becomes serious. The Division will be consulted regarding any additional weed <br />infestation area and any control measures before they are instigated. If infestations of similar <br />weeds to those that are present now are experienced, the current weed control plan will continue <br />to be used. If any new species of weeds are found, Moffat County Weed Control Authority and <br />the Division will be consulted in order to formulate the best plan for the new infestation.

Revegetation Success Criteria <br />Since the pre-mine site is basically dry rangeland and cottonwood groves, revegetation success <br />will be based on coverage achieved by the dryland grasses.
