very old reclamation of the area (at the Seneca II Mine) where alfalfa had comprised a much <br />• larger presence in the seed mixes in the early days and had been considered too abundant. <br />Herbaceous Production <br />Observed production values and derivation of the 2008 herbaceous production standard are <br />compiled / documented in the table below: <br />Yoast 2008 <br /> <br />Vegetation Type Mean Herbaceous Production* <br />(lb/ac) % of Affected Area <br />Sagebrush/Snowberrya 752.3 24.0 <br />Mountain Brusha 868.7 48.9 <br />Aspen Woodlanda 2059.2 24.4 <br />Steep Mountain Brusha 1020.1 2.7 <br />Alkali Sage/West Whtgrs. 716 0.0 <br />2001 Reclamation Area 1660 NA <br />2004 Reclamation Area 1948 NA <br />2006 Reclamation Area 531 NA <br />a Yoast extended reference area values from data collected in 2008 <br />b Yoast extended reference area values from data collected in 2006 <br />As corrected for "allowable" annual and biennial production (i.e., no more than 10 percent of <br />total production allowed, See CDMG 1995, 1.IV.A). Production by noxious weed species, if any, <br />also subtracted. <br />Herbaceous production performance standard (weighted by percent of affected area) = 1135.3 <br />lb/ac. <br />90 percent of performance standard = 0.9 x 1135.3 = 1021.8 lb/ac <br />As can be seen, the observed herbaceous production in both the 2001 and 2004 reclaimed areas <br />greatly exceeded the production standard. As with cover, the young 2006 reclamation was short <br />of the performance standard, largely because much of the production was (expectably) <br />comprised of annuals that (beyond 10% relative production) were excluded. Annual / biennial <br />production is expected to decline in the coming few years as has been observed many times over <br />in older reclamation. <br />n <br />U <br />18
