ABOUT THE COLLECTIONS
Welcome to the Rangeland Ecology & Management archives. The journal Rangeland Ecology & Management (RE&M; v58, 2005-present) is the successor to the Journal of Range Management (JRM; v. 1-57, 1948-2004.) The archives provide public access, in a "rolling window" agreement with the Society for Range Management, to both titles (JRM and RE&M), from v.1 up to five years from the present year.
The most recent years of RE&M are available through membership in the Society for Range Management (SRM). Membership in SRM is a means to access current information and dialogue on rangeland management.
Your institution may also have access to current issues through library or institutional subscriptions.

Seed Physical Characteristics And Germination of hardinggrass (Phalaris tuberosa var stenoptera (Hack.) Hitch.)Commercial samples of harding-grass contained an appreciable number of immature seeds. These seeds were light green in color, generally lighter in weight, and after storage for some time had low viability. When care was taken to harvest only mature seed there was little relationship between seed weight and viability. Seeds from the lower portions of the panicles matured last and had a lower seed weight than those from the top.

Mesquite Control on the Coronado National ForestMesquite is one of the most tenacious invaders of rangeland in the Southwest, and control efforts have resulted in only partial success. Aerial spraying was the most effective and inexpensive of six control methods tried on the Coronado National Forest in Arizona.

Influence of Soil Compaction on Emergence and First-Year Growth of Seeded GrassesAdequate soil preparation will eliminate any compacted layers formed under cultivation and aid in securing a vigorous stand of grass on land converted from cash crop to pasture. Seedling emergence is not affected, but a compacted soil layer depresses the vigor of young grass plants by limiting root penetration and the volume of soil from which moisture for growth can be extracted. The curtailment of forage production is more pronounced with time.

Greater Profit from Livestock in the Intermountain West with Efficient Ranch ManagementLivestock producers are in serious economic difficulty because forage and livestock management have changed very little over the years. If ranchers are to meet the challenge of the cost-price squeeze, they must integrate improved livestock management with more efficient use of their range and meadows. This consists of increasing the quality and quantity of forage to give larger rate of gain on more calves over a longer period of time. It is possible to achieve a severalfold increase in meat production per unit of land and livestock resources.

Grazing Cattle on Sub-irrigated MeadowsUntil recently it was thought that sub-irrigated meadow sites should not be grazed by livestock during the growing season but reserved for hay production. Only the very early spring growth or aftermath was grazed. Grazing cattle on sandhill meadows is a sound practice under proper management. The increased cost of making hay and the inflated values of land in the Sandhills suggest that ranchers should take a look at alternative land uses when planning their grazing-forage program.

Germination Requirements of Scarlet GlobemallowSeed germination percentages of scarlet globemallow can be increased by acid and mechanical scarification. However, the highest germination rate was produced with diethyl dioxide. All treatments interacted with temperature conditions. Alternating temperatures, particularly 12 hour periods at 15 and 22 C, were most favorable in attaining relatively high germination percentages.

Fertilization of Mixed Cheatgrass-Bluebunch Wheatgrass StandsOn both dense and sparse bluebunch wheatgrass stands, cheatgrass became dominant with increasing applications of ammonium sulfate. High and repeated fertilizer applications (80 lb N/A in 4 successive years) depressed bluebunch wheatgrass yield 50%.

Effect of a Wildfire on Idaho Fescue and Bluebunch WheatgrassThe accidental burn of a research site in sagebrush-grass vegetation created an opportunity to investigate some factors which affect the susceptibility of Idaho fescue and bluebunch wheatgrass to damage by fire. The former was more susceptible than the latter. Factors associated with relief increased and those associated with grazing prior to the burn decreased the detrimental effects of fire.

Crude Protein in Rumen Contents and in ForageRumen-fistulated steers consistently selected a diet higher in crude protein than hand-clipped samples of the major available perennial grasses. The excess of rumen protein over grass protein depended on the availability of higher-protein shrubs and annual forbs that supplemented the perennial grasses, and on selection of high-protein parts of the grasses. Since the abundance of these high-protein forages varied greatly with time, the protein content of grass clippings did not reliably indicate the protein level in the steer's diet.

Controlling Blowouts for Forage ProductionBlowouts on sandy soils in the Great Plains can be controlled by leveling hummocks and shaping sharp banks, developing sorghum stubble and seeding warm-season grasses into the stubble. This practice will provide grazeable forage and reduce damage to adjacent areas by wind-blown soil.

Competition in a Blue Grama-Broom Snakeweed-Actinea Community and Responses to Selective HerbicidesIn a blue grama-broom snakeweed-Cooper actinea community, the presence of half-shrubs suppressed the growth of blue grama. Blue grama and forbs were increased when the half-shrubs were reduced by selective phenoxy sprays.

Cattle Grazing Time is Related to Temperature and HumidityTemperature and humidity are recognized to affect the physiology of animals and thus influence their activities including grazing. The temperature-humidity index (T.H.I.) discussed here is an accurate expression for relating these climatic factors to grazing time of beef cattle.

A Low Cost Apparatus for Taking Undisturbed Soil CoresA low cost apparatus for sampling near surface structural properties of soil can be constructed from aluminum irrigation pipe and shop equipment. The device is suitable for taking cores in soils from fine sands to clays.
