• Voles Damage Big Sagebrush in Southwestern Montana

      Mueggler, W. F. (Society for Range Management, 1967-03-01)
      Extensive destruction of big sagebrush in southwestern Montana in the winter of 1963-64 is attributed to a sudden irruption of the population of voles. Such extensive sudden destruction of browse species over wide areas concerns both ranchers and game managers because it can affect production of browse and forage for several succeeding years.
    • Yield and Mineral Composition of Grass Species Grown on Acid Grassland Soils

      Guerrero, F. P.; Williams, W. A.; Martin, W. E. (Society for Range Management, 1967-03-01)
      The objective was to study the use of various grass species, two liming materials, and phosphorus as means of improving very acid, unproductive, grassland soils. Phosphorus applications increased yields of all 10 species at all levels of liming. Liming with a mixture of calcic and magnesium limes increased yield more than either alone. The outstanding performance of veldtgrass was associated with its calcium-foraging ability, which resulted in the highest tissue concentrations of calcium. These guidelines point toward the use of phosphorus and small amounts of limestone, containing both Ca and Mg, with calcium-foraging species for successful forage establishment in acid grassland soils.
    • Range Improvements and Returns to Private Operator in Intermountain Area

      Freed, Dan (Society for Range Management, 1967-03-01)
      Ranchers are squeezed by spiraling inflation-yet the price for the meat they produce is the same as 20 years ago. Some means for meeting this problem are discussed, including range improvements and range management.
    • Supplemental Protein Levels for Calves and Yearlings Grazing on Winter Bluestem Pasture

      Smith, E. K.; Gnadt, K. L.; DeGeer, C. V.; Richardson, D.; Borden, F. W.; Krause, G. F. (Society for Range Management, 1967-03-01)
      One lb/head daily of soybean oil meal pellets was adequate supplemental protein for yearling steers grazing winter bluestem pasture when followed by summer grazing that permitted the steers to compensate for low winter gains. Calves responded to additional supplemental feed, energy or protein with efficient gains.
    • Comparison of Cage Methods for Determining Utilization on Pine-Bluestem Range

      Grelen, H. E. (Society for Range Management, 1967-03-01)
      Plucking herbage from caged quadrats to simulate grazing resulted in lower estimates of yield and utilization than did monthly or yearly clipping of herbage from caged and open quadrats. At the end of the grazing season, estimates of ungrazed herbage did not differ significantly by measurement technique. The overestimate of yield when herbage was clipped once a year was probably caused by greater growth on caged than on open quadrats.
    • Economics of Selected Alternative Calving Dates

      Mueller, R. G.; Harris, G. A. (Society for Range Management, 1967-03-01)
      Shifting calving dates from present early spring to fall or late spring dates offers an opportunity to increase income to range-based cattle operations in north central or north-eastern Washington. Lower death losses and better marketing opportunities more than offset higher winter feed costs. Fall calves also make more efficient use of abundant spring ranges in this region, and dry cows make more uniform use of mountain summer ranges.

    • Design Considerations for Small Pipelines for Distribution of Livestock Water on Rangelands

      Patterson, T. C. (Society for Range Management, 1967-03-01)
      Rapid development of the plastic pipe industry has brought about a revolution in distribution of water on Southwestern rangelands during the past several years. This article discusses and illustrates several considerations important in the planning, designing, and installation of range pipeline systems for distribution of stored water.
    • Livestock Grazing Under Multiple-Use Policy

      Colton, Hugh W. (Society for Range Management, 1967-03-01)
      Good range management is the price ranchers must pay for a place on the public lands. Stockmen must have a positive plan of action to improve the range and develop leadership in land management.
    • Mortality of Rock Goldenrod Sprayed With 2,4-D

      Laycock, William A. (Society for Range Management, 1967-03-01)
      Rock goldenrod, an undesirable range plant, was sprayed with 2,4-D incidental to a sagebrush-control project on the Ashley National Forest. One-half to two-thirds of the rock goldenrod plants sprayed at the rate of 2 pounds per acre were killed. This application killed all mature sagebrush.
    • Exposure May Influence Grassland Establishment

      Dillion, Claude C. (Society for Range Management, 1967-03-01)
      This example of the effect of exposure to grassland establishment can be useful to range management. South exposure sites in this climate will only recover to annual vegetation if perennial plants have been destroyed-that is, within a reasonable period of years. Reseeding would be an important consideration. Deferred grazing may not be beneficial on south exposure sites, but very desirable on north exposures where an excellent perennial grass stand could develop.
    • Germination of Range Plant Seeds at Altering Temperatures

      Ellern, S. J.; Tadmor, N. H. (Society for Range Management, 1967-03-01)
      The germination behavior at alternating temperatures of range plants suitable for seeding semi-arid range was consistent with their behaviour at the fixed temperatures of the alternation cycle, but not with weighted mean daily temperature. Unfavorable temperatures produced a greater retardation of germination than would be expected from their relative influence on the weighted mean. Alternating temperatures did not stimulate germination in the species studied. These data support conclusions from previous work regarding low seedbed temperatures as a factor in the failure of semi-arid range seeding operations.
    • Effects of Herbage Removal on Seedling Development in Cane Bluestem

      Bernardon, A. E.; Huss, D. L.; McCully, W. G. (Society for Range Management, 1967-03-01)
      A single harvesting of as much as 60% of current herbage at any stage of seedling development did not significantly depress root and herbage production of cane bluestem plants grown in a greenhouse. Ninety percent removal was detrimental to subsequent root and herbage growth.
    • Aerial Photography and Statistical Analysis for Studying Behaviour Patterns of Grazing Animals

      Dudzinski, M. L.; Arnold, G. W. (Society for Range Management, 1967-03-01)
      Measurements and their statistical analysis are suggested and tested in the study of sheep distribution in an arid part of Australia. The use of aerial photography and an electronic computer make the job possible and relatively cheap. The possibility of predicting the condition of a range from patterns of grazing behaviour is suggested.
    • Adaption of Grazed Plant Method for Estimating Utilization of Thurber Fescue

      Gierisch, Ralph K. (Society for Range Management, 1967-03-01)
      The grazed plant method of estimating utilization is some times inadequate because a large percentage of the plants may be grazed lightly. Utilization by weight may be no more than 40% when 100% of the plants are grazed. An adaptation of the grazed plant method aimed at overcoming this weakness has yielded very gratifying results for Thurber fescue in the Central Rocky Mountain area.
    • Commercial Fertilizers Influence Crude Protein Content of Four Mixed Prairie Grasses

      Dee, R. F.; Box, T. W. (Society for Range Management, 1967-03-01)
      Nitrogen applied at 33, 100, and 300 lb/acre, alone and with phosphorus, increased crude protein content of blue grama, buffalograss, windmillgrass, and silver bluestem. Addition of nitrogen caused a retention of protein above the level recommended for wintering pregnant beef cows in blue grama, buffalograss, and windmillgrass. Phosphorus fertilization failed to significantly increase protein content or retention.
    • Bitterbrush Seed Collecting—By Machine or By Hand?

      Nord, E. C.; Schneegas, E. R.; Graham, H. (Society for Range Management, 1967-03-01)
      Three methods of harvesting bitterbrush seed that yielded about 5,000 lb clean seed in 1963 were used by the Inyo National Forest. The most economical method of collecting the seed was by Forest Service crews collecting by hand; the most costly was by an experimental browse seed harvester; purchase from private seed collectors was intermediate in cost, but compared favorably with Forest Service crew hand collections. Cost ranged from $47,100 lb clean seed for certain hand collections up to $424 for some machine collections.
