Table 4.4-1 cont. <br /> Premine Ranae Site B Worst Year Recorded, 1979 <br /> A = (30)(.25)(9.95)(.085)(1) =6.3 Tons/A/Yr. <br /> .085 cover factor is based upon 22% herbaceous cover and 17.8% litter cover giving 39.8% effective <br /> cover. <br /> Attached Table 4.4-3, SCS Tech. Note 50 (1982)was used to generate the above factor for cover. <br /> The value assumes that shrubs contribute a canopy cover of 50%, and the herbaceous type is (G). <br /> Postmine Range Site B <br /> A= (30)(.25)(9.95)(.065)(.8) = 3.9 Tons/A/Yr. <br /> Standard: <br /> 29% herbaceous cover and 23% litter(1)(2) <br /> .065 cover factor is based upon 29% herbaceous cover and 23% litter cover giving 52% effective <br /> cover. <br /> Attached Table 4.4-3, SCS Tech. Note 50 (1982)was used to generate the above factor for cover. <br /> The value assumes that shrubs do not contribute canopy cover, and the herbaceous species is (G). <br /> Litter cover factor is .447 of the total effective cover based on 1979 and 1985 premined data, Range <br /> Site B, Table 2. <br /> Premine Ranae Site C <br /> A= (30)(.25)(8.12)(.081)(1) = 4.9 Tons/A/Yr. <br /> .081 cover factor is based upon 23.6% herbaceous cover and 20.0% litter cover giving 43.6% <br /> effective cover. <br /> Attached Table 4.4-3, SCS Tech. Note 50 (1982)was used to generate the above factor for cover. <br /> The value assumes that shrubs contribute a canopy cover of 25%, and the herbaceous type is (G). <br /> Postmine Range Site C <br /> A= (30)(.25)(8.12)(.08)(.8) = 3.9 Tons/A/Yr. <br /> cont. <br /> 4-104 <br /> Revision: TL-4l <br /> Approved: 211% SS <br />
