The straw will be anchored by mechanical crimping or with one of the various tackifying agents available on the market . Only clean grain straw that is free of noxious or prob- lem weeds will be used. Irrigation and Weed Control Use of the planting and mulching methods specified above will result in satisfactory plant establishment, barring abnormally dry conditions. There are no plans to irrigate the reclaimed areas . A number of problem and noxious weeds occur in the mine area. If problem or noxious weeds become established, a weed control program using herbicides will be implemented. The herbicides used will be based on recommendations of the Montrose County Extension Service. Prior to the application of any herbi- cide, approval of their use will be requested from the Division. Pest control may be necessary if infestations seriously impact the reclaimed area. The current Colorado Pesti- cide -Guide from the Colorado State University, Cooperative Exten- sion Service will be consulted in order to determine the proper pesticide to be used. Prairie dogs can become a serious detri- ment to the establishment and maintenance of desirable vegeta- tion. If prairie dog infestations become a serious problem in the reclaimed areas , an appropriate mitigation plan will be developed in consultation with the Division and the appropriate State and Federal wildlife agencies . Reclamation Success The reclamation success will be qualitatively evaluated during routine inspections of the reclaimed sites . These evaluations shall include an assessment of noxious weeds , species diversity and the general health of the vegetation . Results of these evaluations will be included in the annual reclamation reports required under Rule 2 . 04 . 13 . 0 2 . 05-25 July 1991
