The locations of the 30 forage production transects are shown on Map 19, Corley <br />Reclamation - 2014 Transect Location Map. The sample adequacy calculations in Table 2, <br />2014 Statistical Summary and Sample Adequacy Calculations, document that the number of <br />samples required to characterize the parameter of herbaceous forage production at the 90 % <br />confidence interval was 36.5 transects. <br />When sampled in 2013, forage production value averaged 13.61 g/1/4m'- or 485.1 pounds of <br />air-dry forage per acre. When sampled in 2010, forage production averaged 39.38 g/l/4m' or <br />1,403.5 pounds of air-dry forage per acre. When sampled in 2006, forage production averaged <br />19.12 g/ 1 /4m'- or 681.4 pounds of air-dry forage per acre. <br />Species Diversity. According to Table 18, Corley Reclamation - 2014 Plant Cover, the four <br />most dominant plant species were found to contribute 72.17 % of the total relative cover. There <br />were four warm season grass species which contribute more than three percent relative cover. <br />When sampled in 2013, all warm season grass species contributed 15.94 % of the total plant <br />cover or 55.95 % of the total relative cover. The four most dominant plant species contributed <br />21.21 % of the total plant cover or 74.46 % of the total relative plant cover. When sampled in <br />2010, warm season grass species contributed 14.6 % of the total plant cover or 25.57 % of the <br />total relative cover. The four most dominant plant species contributed 39.60 % of the total <br />plant cover or 69.35 % of the total relative plant cover. When sampled in 2006, the four most <br />dominant plant species contributed 18.27 % of the total plant cover or 59.07 % of the total <br />relative plant cover. <br />LOADOUT REFERENCE AREA <br />Plant Cover. The results obtained from the sampling of the 15 plant cover transects on the <br />Loadout Reference Area in 2014, are presented in Table 20, Loadout Reference Area - 2014 <br />Plant Cover. "Total plant cover" averaged 42.33 %, litter cover averaged 32.87 % and <br />"allowable plant cover" averaged 28.87 %. <br />Perennial grasses was the dominant plant life form, contributing 20.60 % of the total plant <br />cover or 48.67 % of the total relative plant cover. Annuals and Biennials was the second most <br />dominant plant life form, contributing 13.53 % of the total plant cover or 31.97 % of the total <br />relative plant cover. Perennial forbs was the third most dominant plant form, contributing 3.93 <br />% of the total plant cover or 9.28 % of the total relative plant cover. Woody plants was the <br />fourth most dominant plant form, contributing 1.13 % of the total plant cover or 2.68 % of the <br />total relative plant cover. <br />Blue Grama as the most dominant plant species encountered, contributing 9.33 % of the total <br />plant cover or 22.05 % of the total relative plant cover. The second most dominant species was <br />Sand Dropseed, which contributed 9.27 % of the total plant cover or 21.89 % of the total <br />relative plant cover. Russian Thistle, was the third most dominant plant species, contributing <br />4.93 % of the total plant cover or 11.65 % of the total relative plant cover. Annual Phacelia, <br />was the fourth most dominant plant, contributing 3.53 % of the total plant cover or 8.35 % of <br />the total relative plant cover. <br />The locations of the 15 cover transects sampled on this site are shown on Map 20, Loadout <br />Reference Area - 2014 Transect Location Map. The sample adequacy calculations in Table <br />2, 2014 Statistical Summary and Sample Adequacy Calculations, document that the number <br />of transects required to characterize the "total plant cover" was 4.8 transects and 13.9 transects <br />for "allowable plant cover" at the 90 % confidence interval. <br />19 <br />
