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.

Yield, Survival, and Carbohydrate Reserve of Hardinggrass in Relation to Herbage RemovalFrequent removal of herbage from hardinggrass plants during the most active period of growth resulted in reduced yields and an increase in plant death. Intensive clipping also appeared to reduce the concentration of carbohydrate reserves in stem bases. Total sugar percent was higher and fructosan percent was lower in intensively clipped plants than in plants clipped only at maturity.

Vegetation Responses to Grazing Management on a Foothill Sheep RangeMeasurements were made of cover, yield, and vigor of plants at five locations in fenced exclosures and on adjacent range moderately grazed by sheep in fall through spring. Under the conditions of this study, four years of either deferment or moderate grazing did not cause major changes in vegetation cover, but there were improvements in the yield composition and vigor of climax-dominant perennial grasses.

Sulphur Dioxide Fumigations of Range Grasses Native to Southeastern ArizonaAn experiment was conducted with 4 sulphur dioxide fumigations each year for 5 consecutive years on the same plots of 3 species of range grasses native to Southeastern Arizona. There were no statistically significant detrimental effects upon the quantity or quality of either the forage or seed produced by these grasses.

Root Systems of Four Desert Grassland Species on Grazed and Protected SitesRoot systems of species of Aristida, Bouteloua and Trichachne were restricted to the upper 7 inches of soil, with depth penetration of roots influenced by characteristics of the soil. Grazing affected root development by reducing the amount of branching of first-order roots and, in 2 species of Bouteloua, by decreasing total root density. Root diameter was not affected.
-
Nutrient Content of Forage Ingested in Morning Compared to EveningForage samples were collected from esophageal fistulated sheep in morning and evening. There was significantly more total protein and gross energy in the diet in the evening than in the morning.

Influence of Grass Vegetation on Water Intake of Pullman Silty Clay LoamWater infiltration rates varied under different plant communities. The soil under blue grama absorbed 8.4 inches of water in a 2-hour period compared with 5.6 inches for windmill grass, 3.8 inches for annual weeds and 2.1 inches for buffalograss. High positive correlations existed between water intake and the amount of standing vegetation, litter, and litter and vegetation combined.
-
Indirect Estimation of Standing CropCriteria such as density and cover are correlated with standing crop of alpine species. Use of these variates, however, in a double sampling design was less efficient than a single clipped sample of equal cost.

Effects of Harvester Ants on Production of a Saltbush CommunityThe presence of denuded areas caused by harvester ants did not lower the production of a Nuttall saltbush community in the Big Horn Basin of Wyoming. Increased saltbush production around the perimeter of the denuded areas compensated for the absence of saltbush within the denuded area.

Effect of Stage of Maturity, Method of Storage, and Storage Time on Nutritive Value of Sandhills Upland HayForage yield was influenced more by differences in year and date of cutting than was nutritive value as measured by metabolizable energy and nitrogen retention. Chemical analysis showed relatively little difference in nutritive value between windrowed, bunched and baled hay, whereas standing forage had lower nutritive value than any of the harvested forages.

Cumulative Effects of Clipping on Yield of Bluebunch WheatgrassBluebunch wheatgrass is particularly susceptible to defoliation injury during the boot stage. At this stage, grazing at ground-level for three or more consecutive years many result in almost complete disappearance of bluebunch wheatgrass from rangeland.

Composition of Two Disclimax Bluejoint Stands in Southcentral AlaskaThe composition of two disclimax bluejoint stands was determined prior to their being committed to grazing use in southcentral Alaska. The stands were essentially monotypic in their grass constituency with forbs and woody species comprising over 50% of the shoot density and well over 60% of the yield. Bluejoint was the only plant of grazing value found in quantity in the two communities.

Brachiaria dura, a Promising New Forage GrassIn Barotseland, Zambia, in Central Eastern Africa a grazing and ecological survey has revealed Brachiaria dura to have unusually favorable characteristics as a forage grass on sandy soils of low fertility. Chief among these characteristics are relatively high protein content, a long period of succulence, and a special root adaption to sandy soil.

Alkali Sacaton: Its Merits for Forage and CoverAlkali sacaton provides fairly abundant forage, is an effective ground cover, withstands relatively heavy grazing, and may offer possibilities for reseeding. It probably is a more valuable grass than generally realized and merits more attention and research.
