RULE 4 PERFORMANCE STANDARDS <br /> Species diversity for the postmine vegetative community will be determined in the same manner <br /> as the premine inventory. Cover data will be collected using a point frame placed in an unbiased <br /> manner. Overall, postmine data collection methods will be similar to premine data collection <br /> methods. Relative cover values(composition)will be determined for each species in the sampled <br /> portion of the reclaimed area. <br /> A similar analysis of Harner's January, 1985 Danforth Project data for the baseline evaluation of <br /> the South Taylor Area (PR-02) yields a similar level of herbaceous diversity: an average of 3 <br /> perennial grasses and 1 perennial forb for the three sampled communities with relative cover values <br /> between 3% and 50%. These values are readily observable on the summary table below that lists <br /> those taxa that exceed 3%relative cover from each of the study's three vegetation communities. <br /> The Number of Native Perennials with Between 3%and <br /> 50% Relative Cover from the Dominant Communities of the <br /> So.Taylor Area - Harner, 1985 <br /> Percent Relative Cover/Total No. <br /> Species Sagebrush Mtn.Shrub Aspen <br /> Agropyron smithii 5.91 <br /> Agropyron splcatum 5.58 <br /> Agropyron trachycaulum 3.07 <br /> Bromus porter! 3.50 3.33 8.38 <br /> Elymus glaucus 7.85 <br /> Poa pratensis 9.08 11.87 10.30 <br /> Subtotal 4 3 3 <br /> Achi//ea lanulosa 3.49 <br /> Lupinus caudatus 5.14 <br /> Osmorhiza occidental/s 6.46 <br /> Subtotal 1 0 2 <br /> Amelachier utahensis 13.73 <br /> Artemisia tridentata 27.13 <br /> Prunus virginiana 4.89 <br /> Quercus gambelli/ 7.47 <br /> Symphoricarpos oreoph//us 12.80 37.07 32.81 <br /> Subtotal 2 3 2 <br /> TOTAL 7 6 7 <br /> Given the aforementioned,the revegetation objective for diversity will be to establish a community <br /> on the reclaimed areas that contain the following; <br /> For areas targeting the livestock grazing subcomponent of the Rangeland Land Use (Pre-2008 <br /> reclamation): <br /> a) At least two cool season perennial grasses with between 3% and 50% relative cover <br /> (composition). <br /> Rule 4 Performance Standards 4-61 Revision Date: 12/20/19 <br /> Revision No.: TR-135 <br />
