<br /> <br />In 1977, the grasses and legumes seeded during 1969 and 1971 ware rated on <br />vigor and ground cover density. Eight grass species were rated good or <br />near-good in vigor and ground cover density: <br />1. Smooth brome was the most vigorous of the species tested. It <br />reproduced by rhizomes. Manchar was the variety tested and <br />recommended. Selections within crosses of this variety and the <br />varieties Sac and Polar brome for revegetation in th.e subalpine <br />are being studied by Dr. Robin Cuany of the CSU Agronomy <br />Department. <br />2. Meadow fox tail was among the more persistent of <:ommercially <br />available grass species for the upper subalpine. It is probably <br />the only one in these trials that will set viable seed at this <br />elevation. <br />3. Creeping foxtail has done. well in the 1971 seedings on the two <br />replications that were on the more moist sites. This species <br />reproduces by rhizomes that have invaded as much as 5 ft into <br />adjacent plots of less vigorous species. <br />4. Timothy has been a reliable choice for seeding in the subalpine. <br />However, it will not set viable seed in the upper subalpine, which <br />is something of a disadvantage for its long term prospects since <br />it is a bunchgrass. It has a small rounded seed which can <br />sometimes establish in small cracks where larger or Fluffy seed <br />cannot. <br />5. Polar brome is a cross of a native brome and smooth brome <br />developed in Alaska. The stand establishment in the 1969 and 1971 <br />seedings was thinner than for smooth brome; however, after 6-8 <br />growing seasons, the ratings are comparable. Polar brome tends to <br />be more bunchy than Manchar. <br />24 <br />
