• `Percent "all-hit" cover (absolute) by herbaceous species as corrected for "allowable' annual and biennial cover (i.e. no more than 10 percent relative cover allowed, See CDMG 1995, 1.IV.A.). "Ratio of relative "first-hit" cover of herbaceous species to relative "all-hit" cover of herbaceous species r-1 LI a Seneca II-W extended reference area values from data collected in 2004 ° Seneca II-WS extended reference area values from data collected in 1997 As can be seen in Figure 1, the allowable total "all hit" herbaceous cover observed in the 2002 reclaimed areas sampled nearly equaled exceeded 90 percent of the standard set by the reference areas. The 90°!° confidence limit well-exceeded 90 percent of the "allowable" cover performance standard (Figure 1). Inasmuch as the 2002 reclaimed areas at the Yoast Mine were only in their second season of growth in 2004, the fact that allowable cover already meets the standard is encouraging. Herbaceous Production Observed production values and derivation of the 2004 herbaceous production standard are compiled I documented in the table below: Yoast 2004 Using the Seneca II-W Phase III Herbaceous Production Standard Vegetation Type.
