• Production. The results of the 30 production transacts on this azea are summarized in Table 8, <br />Pre-1986 Reclamation -Production. The average forage production on this site averaged 28.60 <br />g/1/4mZ or 1,019.3 pounds of air-dry forage per acre. Perennial grasses contributed 23.89 <br />g/1/4mZ or 83.53 percent; perennial forbs contributed 4.51 g/1/4mZ or 15.77 percent; and annual <br />contributed 0.21 g/1/4mZ or 0.73 percent of the total herbaceous forage production on this area. <br />The revegetation forage production success standazd for this area is 7.40 g/1/4mZ or 263.7 <br />pounds of air-dry forage per acre. Since this site averaged 28.60 g/1l4mZ or 1,019.3 pounds of <br />air-dry forage per acre, it can be concluded by direct comparison that this area satisfies the <br />revegetation success standazd with respect to total herbaceous forage production. <br />When RMR sampled this site in 1996, they reported that the average total herbaceous forage <br />production on this reclaimed site averaged 17.24 g/1/4mZ or 614.4 pounds of air-dry forage per <br />acre. When ESCO sampled this site in 1999, they reported that the total herbaceous forage <br />production averaged 19.9 g/1/4mZ or 709.2 pounds of air-dry forage per acre. <br />s <br />The locations of the 30 production transacts sampled on this site in 2005 are shown on Map 3, <br />Pre-1986 Reclamation -Vegetation Transact Location Map. Copies of the individual field data <br />sheets for the forage production sampling of this site are found in Appendix E -Copies of Pre- <br />1986 Reclamation -Production Field Data Sheets. The sample adequacy calculations in Table 2, <br />Kea Mine Sample Adequacy Calculations, document that the number of production transacts <br />required to characterize this site at the 90 percent confidence interval was 26.8. Since the <br />reclaimed area production value (28.60 g/1/4mZ) exceeds the revegetation success standard of <br />7.40 g/1/4mZ with 30 transacts, as allowed in the DMG's proposed reverse null statistical <br />analysis, it can be concluded that this area satisfies the sample adequacy requirements with <br />respect to forage production. Using the reverse null statistical approach the ~ for this data set is <br />10.6345. Since this value is greater than the table t value at an alpha error probability level of <br />0.20 yields a t value of 0.854, thus Ho is rejected and the revegetation total herbaceous forage <br />production on this site is considered successful. <br />Shrub Density. The shrub density counts obtained from the 30 belt transacts taken in this area <br />are summarized in Table 9 Pre-1986 Reclamation -Shrub Density. The average shrub density <br />was determined to equa165.27 shrubs per one hundred square meters or 2,641.5 shrubs per acre. <br />Wyoming Big Sagebrush, Woods Rose and Rubber Rabbitbrush were the most commonly <br />encountered shrubs. The revegetation shrub density success standard for this azea is 1,500 stems <br />per acre. Since this site averaged 2,641.5 stems per acre, it can be concluded that this azea <br />satisfies the revegetation success standard with respect to shrub density. <br />When RMR sampled this site in 1996, they reported that the shrub density averaged 31.2 shrubs <br />per 100 mZ or 1,263 shrubs per acre. When sampled in1999, ESCO reported that the shrub <br />density averaged 36.4 shrubs per 100 mZ or 1,473.1 shrubs per acre <br />The locations of the 30 shrub density transacts sampled on this site are shown on Map 3, Pre- <br />1986 Reclamation -Vegetation Transact Location Map.
