• Composition of Two Disclimax Bluejoint Stands in Southcentral Alaska

      Mitchell, W. W.; Evans, J. (Society for Range Management, 1966-03-01)
      The composition of two disclimax bluejoint stands was determined prior to their being committed to grazing use in southcentral Alaska. The stands were essentially monotypic in their grass constituency with forbs and woody species comprising over 50% of the shoot density and well over 60% of the yield. Bluejoint was the only plant of grazing value found in quantity in the two communities.
    • Vegetation Responses to Grazing Management on a Foothill Sheep Range

      Vogel, W. G.; Van Dyne, G. M. (Society for Range Management, 1966-03-01)
      Measurements were made of cover, yield, and vigor of plants at five locations in fenced exclosures and on adjacent range moderately grazed by sheep in fall through spring. Under the conditions of this study, four years of either deferment or moderate grazing did not cause major changes in vegetation cover, but there were improvements in the yield composition and vigor of climax-dominant perennial grasses.
    • Yield, Survival, and Carbohydrate Reserve of Hardinggrass in Relation to Herbage Removal

      McKell, C. M.; Whalley, R. D.; Brown, V. (Society for Range Management, 1966-03-01)
      Frequent removal of herbage from hardinggrass plants during the most active period of growth resulted in reduced yields and an increase in plant death. Intensive clipping also appeared to reduce the concentration of carbohydrate reserves in stem bases. Total sugar percent was higher and fructosan percent was lower in intensively clipped plants than in plants clipped only at maturity.
