<br />Mr. Dave Stout - 3 - May 13, 1987 <br />CANADIAN STRIP <br />S ep cies % Cover #PLS/AC <br />Thickspike Wheatgrass 18.0 2.75 <br />Western Wheatgrass 10.0 0.8 <br />Canada Bluegrass 4.8 ---- <br />Beardless Wheatgrass 3.6 3.0 <br />In comparing the seeding rates with the resulting cover in the cases above it <br />was generally noted that the approved mix for the Canadian Strip proposed <br />lower seeding rates for the forb and big sagebrush component of the mix than <br />those mines experiencing more representation of those components. In order to <br />increase diversity one suggestion would be to double or triple the seeding <br />rate for forbs and big sagebrush. <br />SEEDING METHODS <br />Two different seeding methods have been employed at the Marr and Bourg Strip, <br />yielding encouraging results with forbs and shrubs. <br />At the Marr Strip, all seeding is performed with a rangeland drill, The <br />graminoids are drilled first and then shrub and forb seeds are drilled, but <br />perpendicular to the rows in which grasses have been sown, In theory this <br />optimizes the distance between competitive grasses and less dominant forbs and <br />shrubs, allowing the forbs and shrubs to develop without grass overcrowding, <br />At the Bourg Strip, all grasses and forbs are drill seeded. All shrub seeds <br />are hand broadcast. The belief is that by seeding the much smaller shrub <br />seeds by hand, the likelihood of then being planted too deep is reduced, <br />therefore greater germination is realized. <br />I hope these comments have been useful <br />feel free to call. <br />If you have any questions, please <br />Sincerel , <br />,,f~~~~a <br />Michael S.
