Those species under the broadcast heading should be broadcast by one of two methods. If a standard <br />rotary seed spreader Is utilized to 'spray' seed across the ground, then a very light harrowing should follow (e.g., light tine method). Under this scenario, a single <br />pass procedure could occur H the rotary spreader Is attached to the seed drill and the seed drill also pulls a light tine harrow. If the second broadcast method is <br />utilized (such as use of a Truax "Trillion" seeder that "dribbles" seed between cultipacker wheels), a second pass with different equipment would be necessary. <br />However, a third scenario would also be a very effective means to plant seed. Under this last scenario, all seed would be broadcast with the use of equipment such <br />as the Truax TrUlion' seeder. This would be a single pass protocol and NO harrowing should be utilized. This last method Is preferred. <br />Seed Mix Comments <br />1) The correct sagebrush seed (Artemisia vaseyana -pauciflora) from sources as close as possible to the Axial Basin <br />will be requested from seed suppliers along with tag verification. A stipulation will be added to bid <br />documentation to require the successful supplier(s) to verify sage subspecies and collection location and elevation. <br />Page 4-3
