• <br />Table 4.4-1 cont. <br />Premine Range 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 Range 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:T-0--:1 I <br />Approved: <br />
