  • Vegetation of the Willa Cather Memorial Prairie

    Nicholson, R. A.; Marcotte, M. G. (Society for Range Management, 1979-03-01)
    The purpose of this study was to analyze the interrelationships of the Willa Cather Memorial Prairie in terms of the characterizing species and types of vegetation. At each of 100 sample stand locations data were obtained on the 244-ha prairie in Webster County, Nebraska, to estimate percent basal cover and percent species composition. Estimates were analyzed quantitatively with the aid of vegetation ordination techniques, from which 15 vegetation types were discerned. Of the 15 types, two accounted for over 40% of the stands: a Kentucky bluegrass (Poa pratensis)-buffalograss (Buchloe dactyloides)-blue grama (Bouteloua gracilis)-type and a Kentucky bluegrass-sideoats grama (Bouteloua curtipendula)-big bluestem (Andropogon gerardi) type. Two secondary types accounted for another 16% of the stands, while the remaining 44% of the stands were fairly evenly dispersed within nine other types. Uplands were predominately Kentucky bluegrass, buffalograss, blue grama, and Japanese brome. Sideoats grama, little bluestem (Andropogon scoparius), and Kentucky bluegrass dominated hillside stands. Most abundant in lowlands were Kentucky bluegrass, sideoats grama, Japanese brome, and big bluestem. Due to the abundance of Kentucky bluegrass, late spring burning was prescribed to improve the condition and productivity of the prairie.
  • Variability in Predicting Edible Browse from Crown Volume

    Bryant, F. C.; Kothmann, M. M. (Society for Range Management, 1979-03-01)
    Biomass estimates were made with regression techniques using crown volume and weight relationships. The log-log function yielded the highest coefficient of determination for Vasey shin oak, plateau oak, Texas persimmon, and honey mesquite. A quadratic function was best for wollybucket bumelia, littleleaf sumac, agarito, and pricklyash. Sugar hackberry showed equally high coefficients with either the linear or quadratic. Coefficients of determination for catclaw acacia, elbowbush, and skunkbush sumac generally were low regardless of the type of regression equation used. When sampled at various periods over the year, predictive accuracy declined for Vasey shin oak and plateau oak through fall and winter but rose again in spring and early summer. For both species, the log-log function was best from late summer to winter but during spring and early summer the quadratic function was best.
  • The Effects of Nitrogen Fertilization on Water Use by Crested Wheatgrass

    Williams, R. J.; Broersma, K.; Van Ryswyk, A. L. (Society for Range Management, 1979-03-01)
    The application of N fertilizer to crested wheatgrass on a dry rangeland site increased yields substantially. In the early part of the growing season when moisture was not limiting, soil moisture was withdrawn from the fertilized site at a higher rate than from the unfertilized plots. At later periods in the growing season the soil water potential curves paralleled each other with the fertilized crop growing under conditions of lower soil water potential. The decreased soil water potential was confirmed when the actual evapotranspiration, as measured by the energy balance method, was examined. The data indicate that for a period following rapid growth in the spring, the evapotranspiration of the fertilized block was less than that of the unfertilized. The soil water potential data indicate that seasonal evapotranspiration was slightly higher on the fertilized plot than on the unfertilized. The water use efficiency, in terms of biomass produced per unit of water used, was much greater for fertilized crested wheatgrass and resulted in increased yields.
  • The effects of grazing intensity on annual vegetation

    Pitt, M. D.; Heady, H. F. (Society for Range Management, 1979-03-01)
    Pastures grazed by sheep at moderate and 1 1/2-, 2-, and 2 1/2- times the moderate stocking rate from 1969-1973 were analyzed for relative changes in cover, herbage productivity, and botanical composition. All four pastures were less productive in 1973 than in 1969, but exhibited similar trends in cover and botanical composition regardless of grazing intensity. Only grazing at 2 1/2 times the moderate stocking rate produced a residual decline in productivity following 1 year of rest from the grazing treatment. However, this decline in productivity was managerially negligible compared to other stocking rates, and would probably disappear within 2-3 years in response to the overriding influence of annual weather, especially precipitation, patterns.
  • The Effect of Nitrogen, Phosphorus and Potassium Fertilization on Chemical Content of Sheep Diets

    Doyle, J. J. (Society for Range Management, 1979-03-01)
    Sixteen mixed breed sheep, 1-2 years old and fitted with esophageal fistulas, were allotted at random to four range pastures in southeastern South Dakota. Two of the pastures (4.9 and 5.3 ha) were treated with 67.2 kg of N, 33.6 kg of P, and 89.7 of K/ha, whereas the other two pastures (6.9 and 7.3 ha) received no fertilizer treatment. Esophageal extruded samples were collected at two time periods (June-July and August) from all animals in the four pastures. Ash, N, cellulose and energy content were determined on all extruded samples. Fertilizer treatment had no significant effect on the nutritive content of the diet selected by the sheep. However, time of collection had significant effects on the protein and energy content of the diet selected. A significant fertilizer-collection period interaction was observed for percentage of ash.
  • Stem Cutting Propagation of Big Sagebrush (Artemisia tridentata Nutt.)

    Alvarez-Cordero, E.; McKell, C. M. (Society for Range Management, 1979-03-01)
    Vegetative propagation of big sagebrush (Artemisia tridentata Nutt.) is often desirable to preserve valuable characteristics of ecotypes for use in disturbed site rehabilitation and range research. Previous research is not clear with regard to procedures for sagebrush propagation. Three experiments were designed to define the influence of synthetic auxin rates, plant dormancy and individual source plants on rooting performance of big sagebrush stem cuttings. Cuttings obtained in the winter during plant dormancy showed greater rooting activity than those collected from actively growing plants. Synthetic auxin, Indolebutyric acid (IBA) treatment, increased root formation as a function of increased auxin concentration but was unable to overcome factors causing seasonal dormancy in cuttings. Source plants varied in the rootability of cuttings. Care should be exercised in selecting only plants that have a high capability for rooting of cuttings.
  • Sequential Development of Shoot System Components in Eastern Gamagrass

    Dewald, C. L.; Louthan, V. H. (Society for Range Management, 1979-03-01)
    The sequence of development of shoot system components was studied from early November 1976 through October 1977 in eastern gamagrass. Tiller production and compound shoot development began in late spring and continued until the first killing frost in mid-October. On shoots initiated in 1977, root development began in early August and peaked in September. Single shoots developed one to six mature phytomers during their first growing season. Reproductive shoot development was first noted in early May, peaked in late May, and continued into October. The proaxes of tillers, single shoots, and compound shoots perennated through the 1976-77 winter dormant period. Shoots that over-wintered as tillers had advanced to the single shoot stage by late August 1977 and had produced from 8 to 20 mature phytomers by the end of the growing season. Compound shoots initiated before 1977 developed into reproductive shoots or died by late May 1977. From May through July high percentages of the shoot system components were in the tiller and reproductive shoot stages. During this period vegetative propagation would probably not be feasible and the use of proper management practices might be more critical than during other periods.
  • Influence of Brush Control on White-tailed Deer Diets in North-Central Texas

    Quinton, D. A.; Horejsi, R. G.; Flinders, J. T. (Society for Range Management, 1979-03-01)
    Botanical composition of white-tailed deer fecal pellets from untreated and brush-controlled areas of the Texas Rolling Plains was studied by microscopic analysis. Deer showed a marked preference for 11 of 54 plant species selected as food from a total of 250 identified on the study area. The bulk of the diet was comprised of mistletoe on non-brush control areas and of prickly-pear on brush-controlled areas. Similarity indices relating habitat across diets as well as diets across a habitat indicated that several habitats had preferred foods removed. These habitats also had low populations of deer. Brush control involving limited removal of noxious species affected dietary selection of deer but did not appear to affect overall deer usage of the habitats studied.
  • Impact of Various Range Improvement Practices on Watershed Protection Cover and Annual Production Within the Colorado River Basin

    Hessary, I. K.; Gifford, G. F. (Society for Range Management, 1979-03-01)
    During 1976 a study of annual production and cover (litter + rock + vegetation) on various range improvement practices was conducted in Utah, Colorado, New Mexico, and Arizona. The range improvement practices studied included gully plugs, contour furrowing, pitting, pinyon-juniper chaining, and various sagebrush control treatments. Results from studies of annual production on treated vs untreated sites indicated that: (a) about 33% of the contour furrowed sites had significant increases in annual production. Best responses were found on loam and clay loam soils, while soils of sandy loam or clay texture indicated a poor response to treatment. Soils classified as typical ustifluvents and ustollic haplargids were most favorable in terms of increased production; (b) annual production on pinyon-juniper chainings was significantly increased across a variety of soil types (growth of trees excluded). The greatest increases in production were measured on sites with loam soils classified as typic haplustolls; (c) neither of the two pitting treatments on a clay and a sandy clay loam site indicated increased annual production; (d) less than 50% of the various sagebrush treatments indicated increased annual production. There appears to be a general trend for best responses on loam soils, though significant decreases in production were also indicated on this type of soil; (e) plowing was the least successful sagebrush treatment studied. Best cover responses on the various range improvement practices were found on contour furrowing treatments on sandy clay loam and loam textured soils and on typic torriorthent or ustic torriorthent soil types. Though significant cover increases due to chaining of pinyon and juniper were noted on 57% of the treatments, on a variety of soil textures and soil types, the increases were uniformly small (tree cover included) and no clear pattern emerged with either soil texture or soil type. Only about 20% of the various sagebrush treatments showed significant increases in cover; 10% indicated decreased cover, and there was no impact on cover on the remaining 70% of the treatments. Pitting treatments in this study had no impact on cover. Age of contour furrow treatments made little difference as to whether there was a significant increase or decrease in either production or cover. Cover data from pinyon-juniper chainings indicate either that significant increases in cover (if they occur) are slightly more dramatic on more recent teatments, or that treatments approximately 11 years old represent conditions most ideal for enhanced cover. The former interpretation is probably more nearly correct. Production data suggests that pinyon-juniper sites chained since 1964 are not as favorable in terms of increased production as those chained prior to 1964. Age of sagebrush treatment had no impact on significant changes in cover; however, a general trend indicated that production increases are slightly higher for more recent sagebrush ripping and sagebrush chaining treatments than for older ones.
  • Grazing Management of Mediterranean Foothill Range in the Upper Jordan River Valley

    Gutman, M.; Seligman, N. G. (Society for Range Management, 1979-03-01)
    A grazing trial with dry beef cows was conducted on an herbaceous Mediterranean range for 10 consecutive years. It included comparisons of continuous heavy (1.2 head per ha); continuous moderate (0.7 head per ha); and rotational moderate (0.8 head per ha) grazing during the first 7 years and rotational heavy (1.3 head per ha) grazing during the last 3 years. Under continuous grazing the liveweight gain per head was higher at the moderate stocking rate, especially during the dry season. Even though the cattle received protein supplement, they began to lose weight towards the end of the summer when the pasture biomass dropped below 700-800 kg dry matter per ha. The liveweight gain per unit area was almost proportional to the grazing pressure and no diminution of the pasture production was recorded as a result of 10 consecutive years of heavy grazing. This result is attributed to the fact that less than 45% of the plant biomass was consumed during the growing season and that the amount of dead standing vegetation had little effect on the growth during the following season. The cattle in the rotationally grazed paddocks gained slightly less weight per head than those in the continuously grazed paddocks. However, on an area basis this difference was not significant. At the end of the grazing season there was more litter in the rotationally grazed paddocks than in the continuously grazed ones. Continuous and/or heavy grazing decreased the relative cover of the grasses. These were replaced by forbs (annual dicotyledons). Under equal grazing pressures the relative cover of grasses was higher in rotational than in continuous grazing. The grazing treatments had no influence on the occurrence of annual legumes, or on Psoralea bituminosa (a common perennial legume) and Echinops viscosus (a widespread perennial thistle).
  • Establishing Kleingrass and Bermudagrass Pastures using Glyphosate and Tebuthiuron

    Baur, J. R. (Society for Range Management, 1979-03-01)
    Tebuthiuron and glyphosate were applied at 1.1 and 2.2 kg/ha in 1976 before land preparation for the sprigging of Coastal Bermudagrass or seeding of kleingrass in the claypan region of Texas. Tebuthiuron at 1.0 kg/ha was re-applied in February 1977 either as the 80% wettable powder spray or as 3.2-mm or 1.6-mm extruded pellets, to a set of plots superimposed across the 1976 plots. Kleingrass top-growth production in 1977 was increased by the preplanting treatment with glyphosate in both rates and tebuthiuron at the low rate. Tebuthiuron at 2.2 kg/ha prevented establishment of kleingrass. Bermudagrass cover was significantly increased by a preplanting application of tebuthiuron at 1.1 kg/ha, but was not affected by preplanting application of glyphosate. Tebuthiuron at 2.2 kg/ha had no effect (beneficial or detrimental) on Bermudagrass cover. Crude protein content was higher in kleingrass from plots treated in 1976 with tebuthiuron at 1.1 kg/ha than in kleingrass from the control plots. No differences in grass stands were attributed to formulation of tebuthiuron re-applied in 1977.
  • Element Content of Crested Wheatgrass Grown on Reclaimed Coal Spoils and on Soils Nearby

    Erdman, J. A.; Ebens, R. J. (Society for Range Management, 1979-03-01)
    Fairway crested wheatgrass [Agropyron cristatum (L.) Gaertn.] was analyzed to determine the possible effects of coal spoils at the Dave Johnston Mine, Wyoming, on the chemical composition of this widely used reclamation species. Concentrations of 8 of the 26 elements tested by analysis of variance showed significant differences between the samples growing in 10-15 cm of topsoil covering the spoils and samples from soils nearby. Samples from the mined areas showed about 50% higher concentrations. Concentrations of manganese and uranium, however, were about 150 and 200% higher, respectively. Concentrations of the trace elements cobalt, manganese, and zinc-essential in animal nutrition-ranged from deficient levels in "control" samples to adequate or marginal levels in samples from reclaimed spoils. The phosphorus content of grasses that grew on spoil material was two-thirds that of the control grasses, to the point where the former may be nutritionally deficient as a cattle forage.
  • Effects of Temperature and Moisture on Phenology and Productivity of Indian Ricegrass

    Pearson, L. C. (Society for Range Management, 1979-03-01)
    Growth in Indian ricegrass commenced in the spring when soil temperatures stayed at 4 degrees C for at least 3 or 4 days. Maximum plant size was attained when (1) soils warmed up early in the spring, (2) soil temperatures were relatively low later in the spring, and (3) additional water was supplied during the spring growth period. Higher soil temperature late in the vegetative phase of growth delayed anthesis approximately 3 days for each degree Celsius above 10 degrees C. Additional moisture early in the season also delayed anthesis. Relatively reliable estimates of foliage biomass and seed biomass were made from measurements of average and/or maximum plant height, average length of longest leaf on each culm, maximum seed stalk height, clump diameter, and number of culms per plant. Measurements of biomass of needleandthread grass indicate that the generalized formulas presented here should be applicable to other cool-season bunch-grasses.
  • Economics of Using Cotton Gin Trash as a Supplemental Feed for Range Cattle

    Young, K. B.; Ahmed, M. U. (Society for Range Management, 1979-03-01)
    The economic use of alternative supplemental feeds was evaluated for a 2,024-ha cow-calf ranch operation in the Texas Rolling Plains. Particular interest was focused on the use of gin trash as a supplemental feed. The estimated value of gin trash compared with alternative supplemental feeds ranged up to $23.75 per ton. Potential ranch carrying capacity and annual net income were expanded with a supplemental feeding program including gin trash.
  • Detecting Depth and Lateral Spread of Roots of Native Range Plants Using Radioactive Phosphorus

    Currie, P. O.; Hammer, F. L. (Society for Range Management, 1979-03-01)
    Radioactive phosphorus (P32) was used to measure root depth and lateral spread of four native plant species which had been subjected to heavy grazing for many years. Compared with root excavation measurements from an earlier study on the same area, rooting depths of all species tested were found to be quite similar by the two methods. Lateral spread differed substantially, however. Roots were found to have a greater lateral spread by the P32 estimate. The isotope method using autoradiography was found to be a sensitive method of determining depth and lateral spread of in situ plant roots in a mixed plant community.
  • Control of Mixed Brush with Tebuthiuron

    Scifres, C. J.; Mutz, J. L.; Hamilton, W. T. (Society for Range Management, 1979-03-01)
    Tebuthiuron pellets, 10 or 20% active ingredient, aerially applied at 2.24 kg/ha active ingredient resulted in excellent control of whitebrush, spiny hackberry, and Berlandier wolfberry in South Texas mixed brush. At 2.24 to 3.36 kg/ha active ingredient, the herbicide appears promising for control of lotebush, blackbrush acacia, ceniza, Texas colubrina, javalinabrush, guajillo, guayacan, desert yaupon and twisted acacia. Rates of 3.36 to 4.48 kg/ha active ingredient, applied as tebuthiuron pellets, appeared promising on huisache but only partially controlled honey mesquite. Tebuthiuron was ineffective on lime pricklyash, Texas persimmon, pricklypear, and tasajillo.
  • Cattle and Calf Losses to Predators—Feeder Cattle Enterprises in the United States

    Gee, C. K. (Society for Range Management, 1979-03-01)
    National losses to predators of beef cattle and calves on farms and ranches with 20 or more cows and market feeder calves or yearlings were investigated. Data are from a sample survey of about 1,800 producers in five major feeder cattle regions. Losses to dogs, coyotes, and all other predators were estimated. Percentage losses are small, but financial losses reach into millions of dollars.
  • Application of an Herbivore-Plant Model to Rest-Rotation Grazing Management on Shrub-Steppe Rangeland

    Hanley, T. A. (Society for Range Management, 1979-03-01)
    A graphical model of a discontinuously stable herbivore-plant system is used to demonstrate analytically relationships between the amount of rest, stocking rate, and seasons of use in rest-rotation livestock grazing management on shrub-grass ranges. All three of these components are important and their interaction determines the system's response. Important points applicable to management are enumerated.
