<br />were also transplanted to the south and southeast of the plots. Prior to <br />transplanting trees and willows in tailing, a volume of tailing about four <br />times the volume of the root spread was dug out, limed, and fertilized with <br />NPK in addition to the area treatment and then replaced. All trees and <br />willows were watered when transplanted and at least twice more during the <br />summer. Willow cuttings were also planted on the west side of <br />Replication 1. <br />The plots were examined on 25 August 1977 after two growing seasons and <br />given the following evaluations: <br />1. Control - fair stand, Replication 1 looked better th,jn the other <br />replications <br />2. 2 tons/acre mulch - good grass stands <br />3. 4 tons/acre mulch - good grass stands <br />4. Rye Seedings - fair to poor rye stands, large amount rye winterkill <br />The area south and west of the plots on the tailing looked good, but <br />consisted mainly of rye. The revegetated soil are had a good grass stand. <br />All willows (clumps) and spruce were alive, but some of the spruce were in <br />poor condition. None of willows from stick cuttings were alive. <br />9.1.7 Alpine and waste Rock Reclamation Research <br />During autumn 1976, research was initiated at the Climax mine site to <br />establish vegetation on steep slopes of open pit rock waste mal:erial. The <br />research consisted of netting the steep slopes to control erosion then <br />seeding with the Climax seed mixture and applying a straw mulch of between <br />60 to 70 lb/acre. Fair germination resulted but the plots were lost after 3 <br />yr to open pit roads. <br />Additional research on methods and materials to vegetate the waste rock was <br />started during 1977 and continued during 1978 when three new research plots <br />were established, to meet the following objectives: (1) revegetz~te the rock <br />15 <br />
