Pure and mixed stands were seeded on sagebrush-bunchgrass range in eastern Oregon to compare yield and competitiveness. The grasses were planted in , , and , and half of each plot was fertilized with ammonium nitrate at 20 or 30 pounds of N per acre. Fertilization studies on sagebrush-bunchgrass range have been underway at Squaw Butte Experiment Station since This report provides a brief summary of results from completed studies and statements of progress from studies underway. General con-cepts and trends are emphasized throughout in preference to detailed presentations of data.

The take-home for managers is to: (1) use a current-year seed lot if possible, (2) purchase seed that has been cold-stored, and (3) have a seed lot that is a year or more old retested for viability immediately prior to pur-chase. Use of current-year seed lots can often be practical.
The areas in between the bushes, which are surprisingly bare, are usually filled in with a desert grass such as cheatgrass, Idaho fescue, bluegrass, or bluebunch wheatgrass. Daniel Moerman’s Native American Ethnobotany lists A. tridentata as one of the ten plants with the greatest number of uses. Introduction. Exotic annual grasses negatively impact rangelands around the world (D'Antonio and Vitousek ) and limit success of efforts to reestablish seeded vegetation in degraded rangelands (Brandt and Seabloom ; Svejcar et al. ).Seeding of desired species following wildfires is a crucial tool used by managers to mitigate ecological damage after wildfires in degraded . If larger grasses, like Pacific reedgrass, Calamagrostis nutkaensis, Deergrass, Muhlenbertia rigens, or California fescue, Festuca californica, are used, they should be placed two to three feet apart, which won't happen if seed is direct sown in the ground. Much seed will be wasted. Here are responses to some of the most frequently asked questions. west, and is the Wyoming state grass. In Wyo-ming, this species is often the first perennial grass to reappear on abandoned, dry farmland. It has good palatability for all classes of livestock and wildlife, and makes very good winter forage. ÒRosanaÓ western wheatgrass is the variety most used in range .
6 5 5-vegetation change between and in relation to pre-exciosure grazing history and concurrent grazing. The Squaw Butte Experiment Station The station, within the sagebrush-bunchgrass type 64 kilometers west of Burns, Oregon, has an elevation ranging from 1, to 1, meters. The southern half of the 6,ha station (Figure 1) is. Perennial grass cover was times greater in seeded compared to non‐seeded areas. Sagebrush cover averaged 24% and seeded and non‐seeded areas at the conclusion of the study. planted using a conventional grass drill or seeder. A grain drill may also be used for these types of native grasses if it can be properly calibrated to plant small seeds at the recommended rate. Eastern gamagrass has a large, clean seed that can be planted with a corn planter. Native grasses are sold in pounds of Pure Live Seed (PLS). Cool season grasses grow in the spring and fall, while warm season grasses grow in the heat of the summer. Graze for short periods of time ( days) and allow long re-growth periods ( days) where the grass has time to recover with no grazing stress. Designate a small sacrifice area or corral to keep animals while grasses are recovering.
