<br />~~ <br />Planting and Seedinx Methods, Once topsoil has been reapplied <br />and leveled, a farm tractor or motor grader mounted scarifier <br />will be used to chisel plow the topsoil. Chisel plowing or <br />scarifying alleviates any compaction and assures a good bond <br />between the graded soil and topsoil. This practice also tends to <br />promote root penetration into the subsoil or spoil material. <br />Following the chisel plowing the area will be seeded with the <br />perennial mixture as shown in Table 10, Proposed Seed Mixture. <br />On steep slopes, seed will be broadcast using a cyclone seeder at <br />twice the drill seed rate. On level areas, all seed will be <br />drill seeded with a heavy duty rangeland drill pulled by a rubber <br />tine farm tractor or small crawler dozer. After seeding a straw <br />mulch will be surface blown or hand spread onto all seeded areas. <br />Next the level areas will be disked to anchor the mulch into the <br />soil and cover the seed. Seed coverage on areas broadcast seeded <br />will be accomplished by chisel plowing and disking where possible <br />and by freeze-thaw action on these roughened soils as they re- <br />ceive moisture from fall and winter storms. <br />If required to meet the performance standards under Rule <br />4.05.18(1)(c), the Operator will transplant, in the Riparian <br />area, the seedlings shown in Table 11. From its experience in <br />this area, the Operator believes that narrow leaf cottonwood <br />trees and willows will naturally invade the riparian area so no <br />transplanting will be required. This natural invasion is already <br />occurring on the flood control berm. <br />. During year 4 of the 10 year bond liability period the Operator <br />will evaluate the necessity of transplants. If it is determined <br />that the total of trees and willows per acre exceeds 1,000 then <br />no transplanting will be necessary. <br />Mulching Techniques <br />As stated earlier, a straw mulch consisting of a native grass hay <br />will be used. The planned application of the mulch will be a <br />minimum of 2,000 pounds per acre on flat areas and 4,000 pounds <br />per acre on steep slopes. <br />• 2.05-41 <br />Revised September 28, 1990 <br />
