Surface Coal Mining in Wyoming: Needs for Research and Management

Wyoming ranks second in the nation in strippable coal resources, with at least 18.9 billion tons of coal presently recoverable. Mining this coal could disturb about 590 square miles (0.6%) of the state's land area. The presence of this disturbed land offers a challenge to, and opportunity for, the varied fields of renewable resource research and management to practice their sciences and arts to allow the nation to use the coal without lasting detrimental effects on other resources.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

A Tool and Method for Extracting Plant Root Soil Cores on Remote Sites

A portable, man-operated tool for extracting intact cores of soil, roots, and above-ground plant parts on sites inaccessible to motor vehicles can be constructed for less than $125.00. Two men can extract up to 125 cores in 4 hours.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

A Low Cost Machine for Separation of Roots from Soil Material

An efficient machine which uses water spray and agitation to separate the roots contained in soil samples from the soil material was constructed from readily available, commercial components for less than $400.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Effect of 2,4-D on Digestibility and Production of Subalpine Herbage

Treatment of forb-dominated subalpine cattle range in the Bighorn Mountains of Wyoming with 2,4-D did not change the in vitro dry matter digestibility coefficients of the grasses or surviving forbs. Forbs and grasses were equally digestible throughout the growing season. Production of total and digestible dry matter was not influenced by 2,4-D, but the proportion of both supplied by grasses was increased.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.

Long-term Effects on Chemical Control of Big Sagebrush

In 1960 and 1961, big sagebrush (Artemisia tridentata) on four cattle ranges in the Bighorn Mountains was sprayed with 2,4-D. By 1971, the canopy cover of big sagebrush was 8-42% of the pretreatment levels, seedling density ranged from 5.7-11.3 plants/120 ft2, herbage production was below the pretreatment levels with the proportion of graminoids about equal to that prior to spraying. Effects of grazing deferment for as long as 3 years after spraying could not be detected.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
