• Responses of Crested Wheatgrass Seeds to Environment

      Wilson, A. M. (Society for Range Management, 1973-01-01)
      Characteristic of crested wheatgrass that favors establishment on harsh rangeland sites is the ability to germinate under conditions of low temperature and of intermittent drought. Subsequent germination was hastened as a result of exposure of seeds to favorable moisture and a temperature of 2 C. Subsequent germination was also hastened as a result of exposure of seeds to water potentials as low as -40 bars. During severe drought, seeds retained much of the advantage they had gained during periods of favorable moisture. After drought, seeds made rapid gains when moisture again became favorable.
    • Rough Fescue (Festuca scabrella Torr.) in Washington

      Hodgkinson, H. S.; Young, A. E. (Society for Range Management, 1973-01-01)
      In Washington, rough fescue occurs primarily north of the 47 degrees latitude and east of the Cascade Mountains. There are two large, well-represented areas. Other locations are represented by small areas, some containing only scattered plants. Rough fescue is very palatable and should be managed as the key species when it makes up more than 15% of the total plant composition. To maintain or improve good stands, no more than 50% of the annual current year's growth should be removed.
    • Snow Amount in Relation to Streamflow and Herbage Production in Western Colorado

      Frank, E. C. (Society for Range Management, 1973-01-01)
      A 10% increase in peak snowpack, due to cloud seeding or natural events, is partly returned as runoff but has little, if any, immediate effect on the productivity and use of mountain grasslands.
    • Taxonomic and Agronomic Variation in Agropyron spicatum and Agropyron inerme

      Chapman, S. R.; Perry, L. J. (Society for Range Management, 1973-01-01)
      The main morphological distinction between bluebunch wheatgrass and beardless wheatgrass is the presence of geniculate awns in the former and the absence of awns in the latter. Open pollinate progenies of plants classified as either A. spicatum or as A. inerme segregated clearly for this trait. This indicates the mere presence or absence of awns does not afford reproductive isolation; thus, the species designation is questionable. In addition, variation for rhizomes was detected in the progenies of bunch type plants, but segregation was not clear cut. Significant variation among progeny means for forage yield was also detected. There is apparent, real potential for varietal development, but care must be exercised in mixing awned and awnless types.
    • Trends in Western Ranch Prices and Values

      Saunderson, M. H. (Society for Range Management, 1973-01-01)
      In the 1930's the western stock ranches were generally underdeveloped and underpriced in terms of their potential. Over the past 40 years, however, a number of factors have, in combination, greatly changed this situation. Now, the picture is that of overpricing, and to such a degree as to cause difficult problems in ranch management and in land management.
    • Western Wheatgrass Germination as Related to Temperature, Light, and Moisture Stress

      Knipe, O. D. (Society for Range Management, 1973-01-01)
      Germination of western wheatgrass was best when seeds were held for 16 hr at temperatures between 55 and 75 F and 8 hr at temperatures between 75 and 90 F daily. Germination was independent of light but was severely reduced by moisture stresses above 1.0 atm.
