6. Describe the strategy for monitoring and evaluating program results (in the <br /> short and long term) including how success will be defined and measured. <br /> A two part pre-treatment inventory of the area will be accomplished using personnel <br /> from the Division of Minerals and Geology and from the Office of Surface Mining. The <br /> project area will be delineated in the field by utilizing stakes and flags and it will be <br /> recorded on a scaled map for future reference. The treatments at Coal Basin will be <br /> evaluated on a set schedule at the same time of year for three consecutive years. Several <br /> photo points will be established to record observations and the treatments will be <br /> evaluated from the same photo points at similar times of year. Range Analysis methods <br /> will be utilized to determine the percent of noxious weed composition on managed <br /> areas. The objective of the treatment program will be a 757o reduction of the noxious <br /> weed population over a two year period. <br /> Monitoring of the success of the treatment program beyond the fall of 1999 may be <br /> accomplished by State and Federal personnel, assuming State reclamation <br /> responsibilities continue beyond that time. <br /> The success of the treatment program involves control of the noxious weed population <br /> without adversely impacting adjacent resources. Therefore, water quality samples will <br /> be obtained from nearby streams immediately before and after treatments to ensure that <br /> unacceptable impacts to these resources do not occur. <br /> 7. Describe the management techniques used in an IPM system of treatments <br /> and the sensible strategies employed to ensure efficient and effective treatments. <br /> Chemical controls-There will be two chemical treatments per year for two consecutive <br /> years. Either Tordon or Banvel will be applied in late spring (June 1-June 15), with a <br /> follow-up treatment on the surviving plants in the fall (September 1-September 15). The <br /> fall herbicide will be either Escort, Tordon, or Banvel. This process will be repeated the <br /> following year. <br /> Biological controls-The primary invasive thistles in this area are plumeless thistle and <br /> Canada thistle. The Colorado Department of Agriculture Insectary has had success <br /> with the weevil,Trichosirocalus horridus, on a musk thistle site located 10 miles <br /> downstream along the Crystal River. We will contact the Insectary and request that they <br /> redistribute the weevil on any infested areas located in or adjacent to the riparian <br /> habitat of Coal Creek. <br /> Cultural controls -Reclamation and re-seeding are an on-going process at the site. Weed <br /> management at the nine will obviously increase the success rate of the revegetation <br /> work. Grasses, (orbs and shrubs are included in the seed mixture to be used. Seedling; <br /> trees will be planted in many areas in order to achieve the desired vegetative diversity. <br /> A list of the typical seed and tree species used in Coal Basin is attached. <br />
