Those species under the broadcast heading should be broadcast by one of two methods. If a standard 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 pass procedure could occur if 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 utilized (such as use of a Truax "Trillion" seeder that "dribbles" seed between cultipacker wheels), a second pass with different equipment would be necessary. 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 as the Truax "Trillion" seeder. This would be a single pass protocol and NO harrowing should be utilized. This last method is preferred. Seed Mix Comments 1) The correct sagebrush seed (Artemisia vaseyana - pauc flora) from sources as close as possible to the Axial Basin will be requested from seed suppliers along with tag verification. A stipulation will be added to bid documentation to require the successful supplier(s) to verify sage subspecies and collection location and elevation. 2.05-53 Revision Date: 3/14/08 Revision No.: TR-72
