Section 780.18(b) Continued. <br />North Park have been well documented. Dargan and Permut (1940:12) reported that <br />wintering sage grouse in North Park were reported to frequent the sagebrush flats and <br />ridges back from the streams. Rogers 11964:211 reported that North Park sage grouse <br />wintered on wind-swept sagebrush ridges. Gill (1967:73) reported that all of the birds <br />observed during winter were restricted to areas of rolling and broken topography along <br />wind-swept ridges that were blown free of snow. Sagebrush densities on these areas <br />(Gill 1965: 150-151) were on the order of 1,792 stems per acre. Iri the most <br />comprehensive study conducted to date, Beck (1975:iii) reported that vegetal <br />characteristics of high use sage grouse wintering areas "were not significantly <br />different Ip7.05) from characteristics of other areas of grouse use." Beck (1975:31) <br />reported sagebrush densities of 3,066 plants per acre were encountered on high use <br />areas. Beck (1975:35) also reported that sage grouse do not have an affinity for areas <br />of specific shrub density as wintering grounds and rather select wintering areas based <br />upon the amount of snow accumulation. Since the woody stem densities proposed by <br />Kerr fall within the range approved in North Park, Kerr contends that the proposed <br />. sagebrush density would be compatible with sage grouse wintering requirements. <br />Finally, Kerr's practical revegetation experience indicates that woody plant densities of <br />2,000 stems per acre cannot practicably be assured. Indeed, to even attempt to attain <br />a materially higher density would entail implementation of prohibitively expensive <br />planting techniques that would probably result in only temporary increases in shrub <br />densities. <br />At the Kerr Tipple Area, sagebrush seed will be incorporated into the revegetation seed <br />mixture as an aid in reestablishing native shrubs. Bare root or containerized <br />transplants of sagebrush and willows will also be planted on the Kerr Tipple Area. <br />Sagebrush and rabbit brush will be planted on the upland portions of the Kerr Tipple at <br />the rate of 1,000 stems per acre !assumes a mortality rate of approximately 30 <br />percent!. On the flat areas of the Tipple, willows will be planted in random clumps at <br />a rate of 100 plants per acre. <br />Planting and Seedling Methods <br />Except where indicated otherwise, the planting and seeding techniques outlined below <br />will be applicable to all areas within the Kerr Mine and Tipple areas. To the extent <br />possible, Kerr will utilize live topsoil handling as an alternative seeding method. Where <br />TR-19 780-78f Revised 11!98 <br /> <br />
