,.•~, <br />Therefore the seed and stocking mixtures proposed for <br />revegetation of this site are geared toward reestablishing <br />_ a big sagebrush - grassland community. All areas disturbed <br />on this site will be drill seeded with a conventional <br />r' rangeland drill at the following PLS rate. <br />- Western wheatgrass 5#/acre <br />(Agropyron smithii) <br />_ Thickspike wheatgrass 5#/acre <br />(Agropyron dasystachyum) <br />Green needlegrass 3#/acre <br />(Stipa viridula) <br />Big sagebrush .5#/acre <br />(Artemisia tridentata) <br />Total 73.5#/acre <br />II-3.6 Stand r^,stablishment <br />Based on average number of seeds per pound and the <br />- herbaceous mixture rates of 13.5-18 pounds pure live seed <br />- per acre, the mixtures discussed above would average in excess <br />of 35 plants per square foot if all seeds germinated <br />_- successfully. The environment (particularly precipitation) <br />_ could not support this seedling density indefinitely, however <br />- seed and seedling mortality will eventually thin the initisl <br />` stand to a density compatible with the environment. <br />r~ <br />- 49 - <br />
