Henderson Mini Permit No. 77-342 <br />,~ February 12, 1~ <br />,~ page 2 <br />CLIMAX SEED MIX <br />Scientific Name <br />Agrostis alba <br />Alopecurus arundinaceus <br />Alopecurus pratensis <br />Astragulus Cicer <br />Bromopsis inermis <br />Dactylis glomerata <br />Festuca arizonica* <br />Festuca ovina <br />Festuca rubra <br />Phleum pratense <br />Poa ampla* <br />Poa compressa* <br />Poa pratensis <br />Secale cereale <br />Trifolium repens <br />*Species added in 1981. <br />Mine Site Update <br />Total 100 <br />Topsoiling and revegetation of mine-yard (Area 1) slopes <br />was continued with the placement of 7,800 cubic yards cif <br />soil. Natural drainage patterns on the mine-yard slopes were <br />identified and topsoil-erosion control measures were de- <br />signed. Diversion trenching at the brow of the topsoi:Led <br />slope above the administration building appeared to be an <br />effective control. <br />Wildflower seeds and shrub seeds were planted on ~iarious <br />slopes in the mine-yard. <br />Preparation for the sinking of the No. 5 shaft for <br />ventilation began. <br />The gravel storage area was moved to a location adjacent <br />to No. 1 settling pond but did not create any new <br />disturbance. <br />Mill Site Update <br />Topsoiling was also continued on the tailing dam face <br />(Area 9). Bench top surfaces are being graded to drain back <br />toward the dam preventing the possibility of sloughing of the <br />brows. A total of 15,500 cubic yards of topsoil was <br />distributed on the higher benches and slopes of No. 1 trailing <br />dam and 4,900 cubic yards on the lower benches and s1oF~es of <br />No. 3 tailing dam during August and September of 1981. <br /> <br /> Percent by <br />Common Name - Variety Wei ght in Mixture <br /> <br />Redtop 3 <br />Creeping Foxtail 5 <br />Meadow Foxtail 5 <br />Cicer Milkvetch - Cicer 4 <br />Smooth Brome - Manchar 15 <br />Orchard Grass 5 <br />Arizona Fescue 4 <br />Hard Fescue - Durar 8 <br />Red Fescue - Pennlawn 8 <br />Timothy - Climax 5 <br />Big Bluegrass - Sherman 3 <br />Canada Bluegrass - Reubens 2 <br />Kentucky Bluegrass - Troy 3 <br />Rye - Balboa 20 <br />White Dutch Clover 10 <br />
