• An Improved AUM for Range Cattle

      Vallentine, John F. (Society for Range Management, 1965-11-01)
      The AUM is a useful tool to range managers if properly defined and applied. A proposal is made that an animal unit be defined as a 1,000 lb dry cow in maintenance or gestation, or its equivalent. It is also proposed that 540 therms of digestible energy (equivalent to 270 lb of TDN) be used for converting dry roughages, silages, and grains to AUM's.
    • Cesium-137 In Bromus tectorum L. In Relation to Precipitation Regimes and Harvest Yields

      Rickard, W. H. (Society for Range Management, 1965-11-01)
      Salubrious spring precipitation increased downy brome yield but not 137 Cs concentration in downy brome.
    • Chemical Composition and Digestibility of Plants From Annual Range and From Pure-Stand Plots

      Van Dyne, G. M. (Society for Range Management, 1965-11-01)
      Comparisons were made of within-plant weight distribution, chemical composition by plant part, and total plant digestion by nylon bag technique of mature annual grasses and forbs collected from pure-stand plots and adjacent range. Under the conditions of this experiment it would be erroneous to grow, harvest, and analyze plants from pure-stand plots in order to make inferences about their nutritive value under range conditions.
    • Control of Prickly Burnet (Poterium spinosum L.) in Rangelands of Southern Judean Foothill Region

      Seligman, N. G.; Katsir, J. (Society for Range Management, 1965-11-01)
    • Control of Saw Palmetto and Recovery of Native Grasses

      Yarlett, Lewis Y. (Society for Range Management, 1965-11-01)
    • Damage to Mesquite, Lehmann Lovegrass, and Black Grama by a Hot June Fire

      Cable, D. R. (Society for Range Management, 1965-11-01)
      Twenty-five percent of mesquite trees were killed on an area with Lehman lovegrass ground cover compared to 8% on an area with black grama. Ninety percent of black grama plants and more than 98% of lovegrass plants were killed. Many new lovegrass seedlings became established on both areas.
    • Grass Seeding Response to Halogeton Competition

      Cook, C. W. (Society for Range Management, 1965-11-01)
      Infestations of halogeton on arid rangelands compete rather severely with wheatgrass and Russian wildrye seedlings. Crested wheatgrass and Russian wildrye compete more effectively with halogeton than tall, pubescent and intermediate wheatgrasses.
    • Hurricane Sourgrass: Scourge or Blessing!

      Judd, B. Ira (Society for Range Management, 1965-11-01)
      A plea is made for research on hurricane sourgrass in the tropics. In spite of its reputation as a troublesome weed under many conditions, it produces feed in time of drought when more palatable species remain dormant.
    • Pesticides: Perils and/or Benefits to Wildlife

      Lawrence, W. H. (Society for Range Management, 1965-11-01)
      Discusses the responsibilities of the range manager in planning chemical pest control programs. They are: (1) Understanding the nature of pest problems, (2) identification of priorities of multiple-use values involved, (3) knowledge regarding the technology of chemicals used.
    • Range Study Tour in the Soviet Union

      Pearse, C. K. (Society for Range Management, 1965-11-01)
      Range management and utilization in the semi-arid and arid zones of Kazakhstan, Turkestan, and Uzbekistan were presented to a group of Fellows who attended a nine-week Study Tour sponsored by F.A.O. Lectures and field trips disclosed the vast extent of these ranges, many in good condition, and the methods of handling of livestock on State and Collective Farms. Methods of research and grazing management and reseeding practices showed many similarities with developments in other regions of the world with similar climate and vegetation.
    • Reindeer Ranching in Fennoscandia

      Scotter, G. W. (Society for Range Management, 1965-11-01)
      Reindeer in Fennoscandia make use of a forage resource which would otherwise be of limited value. This article discusses the status of reindeer ranching, its economics, and the attempts to improve the animals and grazing practices.
    • Species Composition Changes in Seeded Grasslands Converted from Chaparral

      McKell, C. M.; Brown, V. W.; Walker, C. F.; Love, R. M. (Society for Range Management, 1965-11-01)
      Perennial and annual grass composition changes were studied for several years in two locations formerly dominated by chaparral. Hardinggrass, smilo, and desert wheatgrass increased but other seeded perennial grasses decreased in abundance. Annual grasses and weeds fluctuated from year to year but generally increased in abundance.
    • The New Research in Pesticides

      Ennis, W. B. (Society for Range Management, 1965-11-01)
      Agricultural pests cause tremendous losses and they must be controlled. Pesticides are essential but in using them adequate safeguards and operational procedures are necessary to protect against possible adverse effects on man, animals, plants, fish, wildlife, and other values in man's environment. Interim and expanded research is underway to curb the side effects of pesticides. Several new research approaches are being followed in attempts to control a wide range of pests.
    • Time Of Burning As It Affects Soil Moisture in an Ordinary Upland Bluestem Prairie in the Flint Hills

      Anderson, K. L. (Society for Range Management, 1965-11-01)
      Burning bluestem range reduces soil moisture. Study of long-continued annual burning in the winter and at various spring dates shows that earliest burnings cause greatest reductions. Foot-by-foot moisture levels in the upper 5 feet of soil during a 4-year period are considered.
    • Vegetation Response to An Ozark Woodland Spraying

      Halls, L. K.; Crawford, H. S. (Society for Range Management, 1965-11-01)
      Aerial spraying of an Ozark woodland with 2,4,5-T temporarily increased yields of grasses preferred by cattle. Reinvasion of woody plants and heavy grazing by cattle contributed to a subsequent decline in yields of grass. The invading shrubs included many species preferred by deer.
