• T"he following lists the parameters sampled, sampling methodologies, and sampling intensity for the <br />revegetation monitoring program. <br />Sampling Parameters <br />Cover. Cover data includes "fast-hit" and "all-hit" cover by species (both absolute and relative <br />values), total vegetation cover and cover values for litter, rock, and baze ground. If present, covet by <br />mosses and lichens axe also tallied. <br />Production: Production data is collected as total current yeaz's herbaceous standing crop biomass. In <br />sampling for bond release, harvested biomass is separated by life form. Shmb or tree production is <br />not to be sampled. Values aze expressed as gm per 0.5 squaze meter and Ibs/ac, oven-dry weight. <br />Woody Plant Density: The density of shrubs and trees is sampled in reclaimed azeas. Concentrated <br />shrub and tree planting azeas aze delineated and sampled separately from the general reclamation. <br />Values are presented as stems per 100 square meter and stems per acre. <br />Species List: A list of all plant speaes observed during sampling is developed. <br />Species Density: A measure of the number of species per 100 squaze meters determined at the cover <br />sampling locations is developed and refereed to as "spedes Density." <br />IY. SUMMARY <br />• All pit/mining areas have been backfilled and regraded (674 acres). Remaining azeas consist of <br />• roads (ten~inry and perntanent) and andllary facilities (172 acres). <br />• During 2006 (rince end of minim <br />- 193 acres have been backfilled and graded <br />- 142 acres have been topsoiled <br />- 177 acres have been seeded <br />• 2005 vegetation monitoring results (on azeas reclaited in 2001 and 2003) show the revegetation <br />attempts have been successful with an average production of 7,884 16 per acre oven-dry weight. <br />The requirement for Phase III bond release is 1,2501b per acre. <br />• The overall woody plant density (stems/acre) is still low, however the comparison between 2001 <br />(101.2) and 2003 (36.4) reclaimed areas shows a significant upward trend The permit <br />requitement is 200 stems per acre for Phase III bond release. <br />• The spedes density averages 27.4 species per 100 sq. meters. The spedes density is very similar <br />to the results collected from the undisturbed reference azeas. <br />• Over 86,000 trees and shrubs have been planted to date at the Yoast Mine in fenced and <br />unfenced plots. 54,600 trees and shrubs were planted in 2006 <br />• <br />Yoart Mine - 2006 Reclamation Award Nomination page 4 <br />
