possibly infiltrating into Area 4 and Area 5, as past Operations did not seem to set very defined <br /> boundaries. <br /> 4) Operations will proceed west into Area 8, with back fill and reclamation behind to the east. <br /> However, it is difficult to predict a timeline for this operation. MLI predicts approximately 10 <br /> years before operations commence in Area 8. <br /> RE-VEGETATION: Revised Seed Mix: <br /> Permitted broadcast seeding rates from the original 1994 peat mine permit as determined by N. Van <br /> Nostrand, are 3.4 PLS (pounds of pure live seed) of Indian ricegrass, 2.2 PLS of fourwing saltbrush, <br /> and 1.5 PLS of Prostrate kochia. Prostrate kochia is currently considered a noxious wee and will no <br /> longer be considered for the seeding program. <br /> We are proposing the following seed plan, Table 1. Due to the arid environment, we recommend <br /> halving the broadcast seeding rate to ensure germination and growth of native species will be increased. <br /> When too many seedlings grow at once, they compete for very limited resources, such as water. Once <br /> the limited water is exhausted, all of the seedlings fail. By halving the seeding rate, the chances of <br /> native species growth increases because the limited seedlings will have the necessary resources need <br /> for success. <br /> Copied from TR-1, November, 2016 <br /> Table 1 Seed Mixes <br /> Dry rangeland Standard lbs PLS/acre Arid lbs PLS/acre <br /> Sheep fescue 0.5 0.3 <br /> Mountain brome 3.0 1.5 <br /> Big bluegrass 0.5 0.3 <br /> Slender wheatgrass 2.0 1.0 <br /> Ferry's oatgrass 2.0 - 1.0 <br /> Timothy grass 0.25 0.1 <br /> Prairie junegrass 0.151 0.1 <br /> Needlegrass 2.0 1.0 <br /> Bluebunch wheatgrass 1.0 0.5 <br /> Red clover 0.50 0.3 <br /> White dutch clover 0.25 0.1 <br /> Birdsfoot trefoil 0.25 0.1 <br /> Total 12.40 6.2 <br /> Revegetation will be deemed adequate when erosion is controlled, and the vegetation cover is <br /> similar to the surrounding native cover, and satisfactory according to Alamosa County and the San Luis <br /> Valley Weed Management Association standards. <br />
