with a frequency of 10% or greater. On lowland rangeland, six grasses shall be established <br />each with 50% or greater frequency (with four of the grasses contributing more than one <br />percent relative cover each). A minimum of one forb, with greater than 50% frequency, will <br />be present in the lowland rangeland type. <br />Species diversity in the reclaimed areas along the TAHR corridor will be concentrated on <br />the herbaceous component. The shrub component will rapidly reestablish naturally from the <br />surrounding undisturbed vegetation. In the low sagebrush vegetation type associated with <br />the TAHR, baseline studies identified three grasses with relative cover greater than three <br />percent. No forbs with relative cover values of three percent or more were found. Thus, a <br />minimum of three grasses will be established and each will contribute relative cover values <br />of three percent or greater. Each species will not exceed 40 percent relative cover and the <br />total of the three species will not exceed 75 percent relative cover. In addition, two forbs <br />and one shrub will be established, out no relative cover - values a.r e specified. <br />In the meadow vegetation type of the TAHR, four grasses contributed relative cover greater <br />than three percent in baseline studies. No forbs contributed relative cover values of three <br />percent or more, and shrubs were not a notable component of the type. A minimum of four <br />grasses each will contribute relative cover values of three percent or greater in the reclaimed <br />plant communities. In addition, one forb will be established. Each species will not exceed <br />75 percent cover. Species diversity will not be evaluated on areas of the TAHR corridor <br />returned to cropland. <br />Cool season species are expected to dominate due to the environmental conditions of the <br />permit area. Species chosen in the seed mixes reflect cool season adaptations. Three warm <br />season species are included in the rangeland mix. <br />Grazing will be permitted on the reclaimed areas with careful and proper management. <br />Fencing will be installed to reflect logical management units. <br />Based on the information in the revegetation sections of the permit, the Division makes the <br />following findings <br />A. The Division approves the use of certain introduced species in the reclamation seed <br />mix. The applicant has submitted information which shows that the introduced <br />species are desirable and necessary to achieve the approved post- mining land use of <br />range and wildlife use and that the introduced plants are not poisonous or noxious <br />(4.15.2). <br />B. The Division approves the use of cover crops as a means to meet soil stabilization <br />requirements (4.15.4). <br />C. Methods to measure herbaceous cover and production, species diversity, and woody <br />plant density are discussed in Tab 20 of the permit application. These techniques <br />include the use of comparisons to reference areas to set standard for total cover, <br />herbaceous productivity and species diversity. The Division has approved these <br />techniques (4.15.7(1)). <br />Hayden Gulch Loadout 29 November 22, 2011 <br />
