• Two Modifications to the Vegetation Photographic Charting Method

      Claveran Alonso, R. (Society for Range Management, 1966-11-01)
      Two modifications to the vegetation photographic charting method are suggested: The use of Polaroid film to identify species and density in the field and the use of stereoscopic pairs to facilitate detailed analysis of vegetation and site characteristics in the laboratory.
    • Water Intake and Runoff as Affected by Intensity of Grazing

      Rauzi, F.; Hanson, C. L. (Society for Range Management, 1966-11-01)
      Water intake rates on differentially grazed rangeland watersheds were nearly linear with the heavily grazed watershed having the lowest and the lightly grazed watershed the highest rate. Annual runoff was greatest from the heavily grazed watersheds and least from the lightly grazed. Storm characteristics were a factor in the production of runoff.
    • Strengthening Range Management Technical Assistance—The Advisor

      Johnston, A. (Society for Range Management, 1966-11-01)
      The advisor would be more effective if he would forget detail of his discipline and remember principles; if he would learn as much as possible as quickly as possible about the culture he is supposed to advise; and, if he would apply principles in light of cultural limitations. Often the greatest service the foreign advisor can provide is to speak for the technicians of the country, to add the prestige of his position to the recommendations that local technical officers are confident will succeed.
    • Rainfall Effects on Soil Surface Characteristics Following Range Improvement Treatments

      Kincaid, D. R.; Williams, G. (Society for Range Management, 1966-11-01)
      Range improvement treatments-brush clearing, pitting, and seeding to grass-were imposed on twenty-four 6 by 12-foot plots near Tombstone, Arizona. One summer's rainfall of average amount and intensity reduced roughness due to pitting; and such other surface characteristics as erosion pavement and exposed soil approached a state of stability similar to the untreated plots. Surface runoff exhibited little correlation with treatment, but showed a statistically significant negative correlation with crown cover of vegetation.
    • Range Management Worldwide Introduction

      Chapline, W. R. (Society for Range Management, 1966-11-01)
    • Strengthening Range Management Assistance—The Administrator

      Cox, M. L. (Society for Range Management, 1966-11-01)
      This paper is an outline of factors involved in assisting a developing nation with range resource programs. It includes 10 points, begining with the need for a range program, and concluding with final transfer of responsibility to the host government.
    • Technical Assistance in Agricultural Development

      Drosdoff, M. (Society for Range Management, 1966-11-01)
    • Need for a Range Management Approach for Nigerian Grasslands

      McKell, C. M.; Adegbola, A. A. (Society for Range Management, 1966-11-01)
      Development of extensive Nigerian grasslands should follow a range management philosophy. A range management approach offers the best solution for utilization of resources already at hand without the initial need for planting improved forage varieties, fertilization, complicated management schemes, etc. Research information is needed relative to utilizing existing grasslands that can also serve as a base for later development.
    • How the Society Can Help Individual Advisors and Country Workers

      Tomanek, G. W. (Society for Range Management, 1966-11-01)
      This paper suggests that the American Society of Range Management maintain services to visiting trainees to USA and to technicians on overseas assignments; and in other ways help gain needed attention and work on ranges worldwide.
    • How Reliable Is a Forage Chemical Analysis?

      Dietz, D. R.; Curnow, R. D. (Society for Range Management, 1966-11-01)
      Material collected from aspen and mixed meadow grasses was sent to four nutrition laboratories for chemical analysis. The results obtained were closely comparable in most cases, but some discrepancies were noted, especially for one laboratory.
    • Germination of Range Plant Seeds at Fixed Temperatures

      Ellern, S. J.; Tadmore, N. H. (Society for Range Management, 1966-11-01)
      Low temperatures in the 4-10C (39-50F) range were found in the laboratory to delay germination of pasture plants, especially of perenial grasses. Analysis of meteorological data showed temperatures in this range to be prevalent during rainfall periods in the winter (sowing) season in Israel's semi-arid South, and they are considered a critical factor in seeding perennial grasses on arid range. Germination may be improved by agronomic measures, such as plant selection and breeding for cold resistance and seedling vigour, timing of seeding operations, and soil surface treatments to increase soil temperature.
    • Grazing Effects on Grassland Soils of Varanasi, India

      Sant, H. R. (Society for Range Management, 1966-11-01)
      Moisture content, organic content, carbonate, and calcium content of soils were higher in protected fields than in grazed fields. Soils in overgrazed fields were comparatively coarser in texture and lower in total porosity than in protected fields. Soil pH and nitrate contents showed no marked differences.
    • Cultural Conflicts with the Cattle Business in Zambia, Africa

      Larson, F. D. (Society for Range Management, 1966-11-01)
      African cattle production and marketing in Zambia is far below its favorable potential. Stubborn cultural impediments are slowly being overcome. The process involves two basic steps: (1) stimulating the economic wants of the cattle-owning people to the point where these wants become compelling; (2) improving production and marketing practices to the point that sales prices of cattle prove satisfying to the potential seller.
    • Expanding Horizons in Worldwide Range Management

      Pearse, C. K. (Society for Range Management, 1966-11-01)
      Range management must play an increasingly important role in the efforts of the developing countries to increase their output of livestock products. Technical assistance to guide improvement in the management and use of range and pasture resources can best be provided by international organizations. It is essential to establish a philosophy of range management based on sound ecological principles and shared by a body of dedicated range specialists in each of the countries. Gaining acceptance of such a doctrine, and building up such a body of specialists, then becomes the real objective of technical assistance in range management.
    • Application and Integration of Multiple Linear Regression and Linear Programming in Renewable Resource Analyses

      Van Dyne, G. M. (Society for Range Management, 1966-11-01)
      This paper presents preliminary results of formulating quantitatively the influence of site factors on various nutrient production measures and using these relationships in linear programming models to determine the optimum protein production on a foothill range. Site characteristics for optimum protein production were constrained to fall within the range of variables measured, and were constrained to satisfy certain inherent relationships known about these variables. This example shows a useful application of an operations research technique to resource evaluation problems.
    • Chemical Control of Alpine Avens

      Smith, D. R.; Alley, H. P. (Society for Range Management, 1966-11-01)
      Both 2,4-D and 2,4,5-T at 1, 2, and 3 lb/acre gave about 98% control. By the third growing season, grasses filled voids left by avens and other forbs.
    • Cliffrose Browse Yield on Bulldozed Pinyon-Juniper Areas in Northern Arizona

      McCulloch, C. Y. (Society for Range Management, 1966-11-01)
      Where large pinyon and juniper trees were killed 4 to 6 years earlier by bulldozing, cliffrose browse yield was 3.5 lb/acre greater than on untreated sites. Most of the gain represented growth on cliffrose plants established before treatment.
