The seed mixture was selected to vegetate the disturbed areas with a specie consistent with the post-mine land <br />use. Seeding recommendations follow: <br /> <br /> POUNDS <br />COMMON NAME BOTANICAL NAME PLS # / AC. <br />Mat Salibarush Atriplex Corrugata 2.0 <br />Scarlet Globemallow Sphaeralcea Coccinea 0.5 <br />Shadscale Saltbrush Atriplex Confertifolia 2.0 <br />Galleta Hilaria Jamesii "Viva" 2.0 <br />Indian Ricegrass Orysopsis Hymenoides <br />" <br />" 3.0 <br /> Paloma <br />Seeding will normally be done in the fall or spring when temperatures and adequate soil moisture is <br />present. Seeding will be accomplished by either broadcasting, or by using a seed drill. If broadcasting <br />is used, seed rates will be doubled. Due to the nature of the overburden and topsoil found in the area; <br />hay, straw or fiber mulch is considered to be necessary. Fiber mulch will be applied at a rate of 2,500 <br />pounds per acre. If straw mulch is used it will be certified "weed free" and applied at a rate of 2,000 <br />pounds per acre and either crimped or "tacified" at 150 pounds per acre. "Biosol" fertilizer will be <br />applied at a rate of at least 1000 pounds per acre. <br />WEED CONTROL - If necessary, weed control measures will be employed for the control of noxious weed <br />species. Weeds listed on Mesa County's Noxious Weed List are of primary concern. Of the 19 listed weeds, <br />Russian knapweed (Acroptilon repens L.) and whitetop (Cardaria drabs) are present on the proposed wetland <br />site. Tamarisk (Tamarix ramossissima), also onsite, appears as a "species recommended for control" on the Mesa <br />County list. <br />The whitetop will be treated once with EscortO in a concentration of one ounce per acre in the Spring at first <br />bloom; or alTernatively, in the Spring with a solution of six ounces of glyphosate (RoundupC~) plus two ounces of 2- <br />4-D per gallon of water before flowering and again after flowering. <br />Russian knapweed will be treated with a two percent solution of CurtailO in the Spring between bud and bloom or <br />in the Fall just prior to dormancy. <br />Tamarisk will be controlled at any time of year by cutting trees with trunks greater than two inches in diameter to <br />within six inches of the ground and treating the cut stumps with a mixture of Garlon 4® and avegetable-base crop <br />oil in a 25% solution. For trees with trunk diameters of less than two inches, a basal spray technique with a 20% <br />solution is effective. Alternately, stands of tamarisk may be bulldozed or burned one year and the re-sprouts <br />treated with the basal spray technique the following year. <br />The stockpiled overburden and topsoil will be monitored for noxious weed growth and treated, if necessary, <br />according to the above schedule. <br />Revised October, 2002 <br />
