  • Toxic Extracts in Ponderosa Pine Needles that Produce Abortion in Mice

    Cogswell, C.; Kamstra, L. D. (Society for Range Management, 1980-01-01)
    A reliable method to measure presence and quantity of the toxic factor in needles of ponderosa pine (Pinus ponderosa Laws.) was developed using embryo implantation and gestation in laboratory mice as the basis of the assay. The abortiofacient factor was present in both aqueous and acetone extracts of ponderosa pine needles. Control animals had significantly (P<0.1) greater number of viable embryos at 124, 148, and 172 hr post-coitum than mice fed pine needle extracts. A gestation study verified results from the implantation experiment, as few mice fed pine needle extracts delivered normal litters. Frequently, mice receiving the concentrated aqueous extract had diarrhea and decreased feed intake. Failure of implantation by 124 hr postcoitum in bred mice fed aqueous or acetone extracts of ponderosa pine can be used as an index of the risk involved in grazing ponderosa pine ranges, but cannot be used to predict losses.
  • The Rangelands of the Sahel

    Le Houerou, H. N. (Society for Range Management, 1980-01-01)
    This article is an attempt to review and synthesize the present state of knowledge on the Sahel rangelands in a concise way. Ecological conditions, land use practices, livestock numbers, and livestock production systems are briefly analysed. Range types, dynamics, production, development strategy, and outlook are also reviewed. The conclusion that emerges is that the Sahel should be kept as breeding ground and included in a livestock production stratification strategy which should also involve the higher potential zones further south in the Sudanian and Guinean ecological zones. Such a development stategy implies the improvement of the conditions of range utilization in the Sahel, in particular a better definition of basic resources ownership (range and water) as well as of the marketing and prices policies.
  • Seasonal Patterns of Soil Water Recharge and Extraction on Semidesert Ranges

    Cable, D. R. (Society for Range Management, 1980-01-01)
    Soil water is recharged in the semidesert Southwest during the usual winter precipitation season, and again during the usual summer rainy season. The amount and depth of recharge varies widely depending primarily on the amount of precipitation, and secondarily on storm character, soil texture, vegetation cover, and evapotranspiration. Soil water depletion patterns and amounts differed among species, between plants and bare soil, and between seasons. Compared to evaporation from bare soil, plants extracted water much faster, but at more variable rates. Essentially all available soil water was used by plants or evaporated during most depletion periods.
  • Management of Wild Ungulate Habitat in the Western United States and Canada: A Review

    Scotter, G. W. (Society for Range Management, 1980-01-01)
    Conservation, use, and development of adequate habitat are probably the most important factors in wild ungulate management. As the various demands on the habitat heighten, pressure on this dwindling resource will increase. To maintain viable wild ungulate populations with high sustainable yields for the future enjoyment and use, habitat management will have to be intensified. This review discusses rehabilitation of wild ungulate habitat, modification of range and forest practices, better use of existing habitat, and manipulation of numbers and distributions of wild ungulates. The amounts and kinds of habitat needed to maintain wild ungulate populations require more long-term research and better application of existing knowledge. Determination of the requirements for a given species will demand a much better understanding of how animals select and use habitat.
  • Influence of Natural Mulch on Forage Production of Differing California Annual Range Sites

    Bartolome, J. W.; Stroud, M. C.; Heady, H. F. (Society for Range Management, 1980-01-01)
    Manipulation of natural mulch on nine experimental plots in California annual grassland representing a range of mean annual precipitation from 160 to 16 cm provided information useful for grazing management. Peak standing crop correlated highly significantly with precipitation. Response of peak standing crop to five levels of natural mulch ranging from zero to 1,120 kg/ha differed with site. Three types of sites distinguished by mean annual precipitation and plant species composition were identified. On sites with significant numbers of perennial grasses and more than 150 cm of mean annual precipitation, maximum standing crop is reached when more than 1,120 kg/ha of mulch is present on the ground at the beginning of the fall growing season. Peak standing crop results from 840 kg/ha of mulch on sites containing the annuals Bromus mollis and Erodium botrys and with between 100 and 65 cm of mean annual precipitation. Mulch did not significantly influence standing crop in regions dominated by Bromus rubens and Erodium cicutarium and receiving less than 25 cm of mean annual precipitation. Annual grassland response to mulch and grazing is highly site specific, yet the resilience of annual rangelands also allows rapid recovery from overuse.
  • Influence of Climate on Annual Production of Seven Cold Desert Forage Species

    Fetcher, N.; Trlica, M. J. (Society for Range Management, 1980-01-01)
    Stepwise regression analyses were used to examine the relationships between annual production of seven cold desert forage species and climate variables at different periods of the year. No significant regressions were found for production of Artemisia arbuscula var. nova, Oryzopsis hymenoides, or Sitanion hystrix with precipitation and temperature. For Artemisia tridentata, Atriplex confertifolia, Ceratoides lanata, and Atriples gardeneri, significant (p<.05) regressions were found between annual production and precipitation during the spring months. For Artemisia tridentata and Atriplex confertifolia, mean monthly temperature in March and April also appeared in the equations. Multiple regression was used to test the null hypothesis that the amount of variation in annual production explained by winter (November-February) or spring (March-June) precipitation was equal to zero. No significant (p<.05) linear relationship was found between winter precipitation and production, whereas such a relationship appeared more likely for spring precipitation and production of Artemixia tridentata, Ceratoides lanata, and Atriplex gardeneri.
  • Habitat Requirements of the Golden-Cheeked Warbler: Management Implications

    Kroll, J. C. (Society for Range Management, 1980-01-01)
    Characteristics of nesting and wintering habitats of golden-cheeked warblers (Dendroica chrysoparia) were studied from 1973-1978. Golden-cheeks are obligatively dependent on Ashe juniper (Juniperus ashei) for nesting materials and singing perches, but are equally dependent on scrub-oak (Quercus durandii breviloba) for foraging substrates. Golden-cheeks preferred to forage (73.6% of total observations) in hardwood species. Stepwise discriminant analysis suggested that quality nesting habitat differs from poor nesting habitat by having older (greater than or equal to 40 yrs.) Ashe juniper, lower juniper densities and higher densities of oak (juniper-oak ratio = 1.35 to 1). Structure of scrub-oak (mostly Q. oleoides) in the wintering habitat (La Esperanza, Intibuca Dept., Honduras) was structurally similar to that in the nesting habitat. Golden-cheeks were observed feeding in the shrubby understory.
  • Forage Quality Measurements and Forage Research—a Review, Critique and Interpretation

    Beaty, E. R.; Engel, J. L. (Society for Range Management, 1980-01-01)
    Forage makes up a major portion of the rations of cattle and rate of animal gains varies widely within and among forage species grown. Forage production research has been highly productive, but research on increasing forage intake and digestibility by cattle has not been as successful. The literature suggests that resistance to change in specific gravity increases with the age of the plant, particularly with stems, and may increase time required for passage through the rumen and gut, reducing rate of intake. Leaves and leaf sheaths of grasses live for only part of a season and when they die soluble contents are translocated out to young tissue, leached by rainfall and metabolized by bacteria or by the plant leaf itself. Digestibility of dead leaves ranges from 40 to 60% of that of green leaves and when leaves die 15 to 40% of total production may be lost. Plant parts, leaf, leaf sheath, and stem, differ significantly in digestibility and rate of consumption. Variations in quality among forage cultivars may represent a basic difference in the amount of each component that is produced or is present when being grazed. Cultivars high in leaf content will be higher in quality than cultivars which produce more stem. Pasture or range management which maintains green leaves should produce more total forage and more total digestible nutrients than management which allow stems and dead leaves to accumulate. It is hypothesized that by understanding shoot growth in grasses and managing to prevent stem production and leaf death, forage quality over a season can be stabilized at a digestibility of 65% or higher. When processing forage samples, data on green leaves, leaf sheaths and stems, forage quality and digestibility, need to be collected to be descriptive of the species. On pastures or ranges, species with reproductive tillers tend to become stemmy in the summer, requiring defoliation to remove the stems and N application to activate new shoot growth. This is different from those species producing vegetative tillers where, over a season, dead leaves tend to accumulate. On perennial grass species with vegetative tillers, rate, and time of N application should be adjusted to stimulate tillering and green leaf growth. Under range conditions spring N application stimulates the growth of annuals which compete with the perennials. Thus, effective pasture management is expected to reflect manipulation of green leaf producton and utilization in the predominant tiller type present, usually the perennial.
  • Forage Intake in Two-Year Old Cows and Heifers Grazing Blue Grama Summer Range

    Rosiere, R. E.; Wallace, J. D.; Pieper, R. D. (Society for Range Management, 1980-01-01)
    Forage intake was estimated in 2-year-old cows and 2-year-old heifers grazing blue grama summer range by using the fecal output-indigestibility ratio technique. Heifers consumed only 67% as much forage as cows (1.4 vs 2.1 percent of body weight). Forage intake by cows was greater in earlier stages of lactation than in later stages (2.5% of body weight at 90 days postpartum vs 1.7% of body weight at 150 days postpartum). Considerable variation occurred in estimated levels of intake.
  • Fire Temperatures in Grass, Shrub and Aspen Forest Communities of Central Alberta

    Bailey, A. W.; Anderson, M. L. (Society for Range Management, 1980-01-01)
    Soil surface temperatures averaged 186, 398 and 393 degrees C for grass, shrub and forest communities, respectively. Higher temperatures were associated with head fires, more fuel and with woody fuels. Temperatures in headfires were higher but more variable than in backfires for the three types of vegetation. The aspen forest was found to be the most difficult to obtain complete burn coverage. Headfires and backfires went out more readily in this type than in shrubland or grassland.
  • Effects of the Plains Pocket Gopher (Geomys bursarius) on Rangeland

    Foster, M. A.; Stubbendieck, J. (Society for Range Management, 1980-01-01)
    Gophers reduced forage production by 18 to 49% on sands and silty range sites in western Nebraska. Determination of percentages of the soil surface that were bare, covered by litter, and occupied by plant bases showed that gopher-disturbed areas contained greater percentages of bare soil and litter than did undisturbed areas. Basal cover of vegetation was highest on undisturbed areas. Frequency of vegetation on gopher mounds of different age was determined. Most perennial grasses increased in frequency on mounds with increasing mound age, while annual grasses and forbs decreased.
  • Deer and Cattle Diets on Summer Range in British Columbia

    Willms, W.; McLean, A.; Tucker, R.; Ritcey, R. (Society for Range Management, 1980-01-01)
    A study was made on the forage selection of mule deer and cattle on summer range in the Douglasfir zone. Both ungulates showed a high preference for clover, willow, and fireweed. When the availability of these forages was not limiting, the percent of diet overlap was high. As their availability declined, diet overlap decreased as both deer and cattle were forced into their individual food niche. For cattle the niche was grass, while for deer it was shrubs. The effect of declining availability of preferred forages on the dietary composition was less for deer than for cattle. Presumably the greater ability of deer to be selective permitted them to utilize those forages despite reduced availability.
  • Changes in Diet and Nutrition with Increased Herd Size in Texas White-tailed Deer

    Kie, J. G.; Drawe, D. L.; Scott, G. (Society for Range Management, 1980-01-01)
    A high-density deer herd within a 391-ha predator exclosure on the Welder Wildlife Refuge was sampled to investigate diet and nutritional levels. Annual diet of the exclosure herd averaged 76% forbs, 21% grasses, and 3% browse. Deer from the surrounding area consumed 87% forbs, 10% grasses, and 3% browse. Fawns from both herds consumed less grass during the first 9 months of life. The exclosure herd also exhibited lower ruminal levels of crude protein, higher levels of calcium, and higher calcium to phosphorus ratios than the surrounding herd. It was hypothesized that with increased herd size, deer within the predator exclosure overutilized the most desirable forb species and were forced to consume more grasses. The resulting decrease in nutritional level was responsible for changes in health, condition, and population parameters.
  • Application of the Universal Soil Loss Equation to Rangelands on a Per-Storm Basis

    Trieste, D. J.; Gifford, G. F. (Society for Range Management, 1980-01-01)
    The Universal Soil Loss Equation was evaluated in rangeland conditions on a per-storm basis utilizing rainfall simulator data collected on 2,805 plots representing a variety of conditions in the western United States and Australia. The popular agriculturally oriented equation explained sediment yield with a low degree of accuracy for most rangeland conditions. The equation gave its most accurate predictions on mining spoils. Optimizing the equation with suitable exponents resulted in only a slight improvement in accounting for the variability in sediment yields.
  • An Inexpensive Tool for Unrolling Barbed Wire

    Knight, R. W.; Wood, M. K.; Blackburn, W. H. (Society for Range Management, 1980-01-01)
    A hand tool for unrolling barbed wire is described which is advantageous in that it requires only one person to operate, snags are easily corrected, works in tight places, and can be constructed totally from scrap materials.
