NUISANCE WEEDS TEAT SHOULD BE ADDRESSED <br />The following is a list of the troublesome weeds of Larimer <br />County that should be controlled if needed: <br />a.

CONTROLLING ABOVE LISTED WEEDS <br />All of the above weeds can be controlled or eradicated by using <br />any or all of the following methods, mechanical, biological, or <br />chemical control depending on species. The Operator will have <br />a qualified weed control agent observe the mine for possible <br />noxious weeds and advise the Operator on how noxious species <br />should be treated. Initially it may require semi - annual spray- <br />ing and /or mowing to control the problem weeds and digging the <br />woody species, but eventually we expect to revert to an annual <br />control program to maintain the site. <br />Prepared by Environment, Inc. 3/12/14 <br />
