Vegetation Information <br />Introduction <br />EXHIBIT J <br />Following disturbance from past mining activities, most of the proposed Treiber Lakes site has <br />been re- seeded with a mixture of native grass species. The individual species were selected <br />based upon their diverse genetic characteristics that make each one uniquely suited to the soils <br />and climate of the proposed permit area. Differences in and between warm and cool season <br />grasses, bunch and turf forming grasses, and short, mid, and tall grasses were specifically chosen <br />to add to the genetic potential for the grasses to adapt and thrive. <br />Current Conditions <br />Two seed mixtures were used for revegetation. One seed mix was specifically used for dry <br />slopes and upland areas, and the other mix was used in moist and intermittently inundated areas <br />within ten feet of the lake shorelines. In addition to the grass seed mix, cottonwoods, willows, <br />and cattails were planted along the shorelines. The current vegetation distribution is illustrated <br />on Exhibit C -3, Vegetation Map. <br />Upland areas were seeded with a mixture of Western wheatgrass, Switchgrass, Big bluestem, <br />Inland saltgrass, Indian ricegrass, and Sand dropseed. In the moist, low lying areas adjacent to <br />the ponds, revegetation included Reed canarygrass, Inland saltgrass, Alkali sacaton, and Sand <br />dropseed. <br />Grasses across much of the proposed Treiber Lakes site have become well established. Mowing <br />and other weed control techniques appear to have minimized growth of nuisance and unwanted <br />weeds. Currently, the vegetation cover serves to stabilize slopes and lake shorelines. <br />Reclamation <br />During mining and reclamation activities for the Treiber Lakes site, slurry wall installation will <br />disturb upland areas and potential slope regarding may disturb existing lake shorelines. With <br />reservoir water level fluctuations and routine slope maintenance, revegetation of the reservoir <br />shorelines with a moisture dependent grass seed mix is not practical. The reclamation seed <br />mixture for disturbed areas following slurry wall installation is comprised primarily of upland <br />grasses and is taken from the 1987 Home Office Mine 112 Operation Reclamation Permit <br />Amendment reclamation plan. This will provide consistency with the established grass <br />community on the site. <br />( <br />Treiber Lakes <br />DRMS 112 Permit Application <br />Page 20 <br />
