U::`:d!Ufai ~4250UfCe8 The requested information, with the exception of level of confidence, was provided in the baseline information. See Tables 3.5-1 in both McClane and Munger Canyon applications; Permit No. C-004-81 and File No. C-020-81, respectively. Table 1, attached hereto, provides the level of confidence achieved by both a one-tailed and two-tailed 't' test as indicated. 11. WOODY PLANT DENSITY REVEGETATION LEVELS It should be noted that all vegetation at McClane and Munger has been extensively disturbed by abusive grazing practice for many years. The net result has been an increase in the density of woody plants and undesirable weedy species (such as cheatgrass) and a correspond- ing decrease in desirable native graminoid cover and production. The greatest potential productivity for the sites will result with a restoration of the native grasses, not the woody species. An increased herbaceous component and reduced woody plant density will achieve the post-mining land uses of rangeland and wildlife habitat. Many of the woody plants such as shadscale and greasewood dominating these vege- tation types have a limited value to wildlife. However, the native grasses are not only valuable to wildlife, but also support the range- land post-mining land uses. With the exception of the Juniper Woodland, all woody plants will be planted in patches amid the herbaceous areas. Such mosaics maximize the value to wildlife by creating vegetational structure and "edges." It should also be noted the total combined acres of disturbance at Munger and McClane is quite small for all vegetation types. Acreages of disturbance (existing and planned) are as follows: greasewood shrubland, 8; big sagebrush, 11; shadscale, 20; and juniper, 8.
