Big Sagebrush by Bruce Leigh Welch Pdf

Pioneers traveling along the Oregon Trail from western Nebraska, through Wyoming and southern Idaho and into eastern Oregon, referred to their travel as an 800 mile journey through a sea of sagebrush, mainly big sagebrush ( Artemisia tridentata). Today approximately 50 percent of the sagebrush sea has given way to agriculture, cities and towns, and other human developments. What remains is further fragmented by range management practices, creeping expansion of woodlands, alien weed species, and the historic view that big sagebrush is a worthless plant. Two ideas are promoted in this report: (1) big sagebrush is a nursing mother to a host of organisms that range from microscopic fungi to large mammals, and (2) many range management practices applied to big sagebrush ecosystems are not science based.

Countering Misinformation Concerning Big Sagebrush by Bruce Leigh Welch Pdf

This paper examines the scientific merits of eight axioms of range or vegetative management pertaining to big sagebrush. These axioms are: (1) Wyoming big sagebrush (Artemisia tridentata ssp.wyomingensis) does not naturally exceed 10 percent canopy cover and mountain big sagebrush (A.t.ssp.vaseyana) does not naturally exceed 20 percent canopy cover; (2) As big sagebrush canopy cover increases over 12 to15 percent, bare ground increases and perennial grass cover decreases; (3) Removing, controlling, or killing big sagebrush will results in a two or three or more fold increase in perennial grass production; (4) Nothing eats it; (5) Biodiversity increases with removing, controlling, thinning, or killing of big sagebrush; (6) Mountain big sagebrush evolved in an environment with a mean fire interval of 20 to 30 years; (7) Big sagebrush is an agent of allelopathy; and (8) Big sagebrush is a highly competitive, dominating, suppressive plant species.

Wildlife Habitats in Managed Rangelands by J. Edward Dealy Pdf

Plant communities in the Great Basin of southeastern Oregon are described, and a field key is provided. The value of a plant communitys vertical and horizontal structure and the seasonal availability of its forage are examined in relation to wildlife habitat in managed rangelands. Further, the importance of individual and combined plant communities to wildlife in managed rangelands is discussed, and management alternatives are presented.

Saval Ranch Research and Evaluation Project by Max C. Fleischmann College of Agriculture. Renewable Resources Center Pdf

"The Saval Ranch Research and Evaluation Project was initiated in May, 1978. The overall objective is to evaluate the effects of livestock grazing management systems and range improvement practices on livestock production, vegetation, fish and wildlife and their habitat, watershed hydrology, water quality, economic factors, and other resource values. The Project is conducted on the Saval Ranch, privately owned enterprise located in northeastern Nevada. The ranch, livestock and grazing allotment are made available for this interdisciplinary study by the Saval Ranching Co. ... Funding and support are provided by the Bureau of Land Management, U.S. Forest Service, Agricultural Research Service, and Agricultural Experiment Station, University of Nevada, Reno. This progress report describes the allotment management and results of scientific investigations for the period October 1, 1982 through September 30, 1983. In addition, it provides a summary of organizational changes that have occurred since October 1, 1983"--Page 1

Bird Habitat Relationships Along a Great Basin Elevational Gradient by Dean E. Medin Pdf

Bird censuses were taken on 11 study plots along an elevational gradient ranging from 5,250 to 11,400 feet. Each plot represented a different vegetative type or zone: shadscale, shadscale-Wyoming big sagebrush, Wyoming big sagebrush, Wyoming big sagebrush-pinyon/juniper, pinyon/juniper, pinyon/juniper-mountain big sagebrush, mountain big sagebrush, mountain big sagebrush-mixed conifer, mixed conifer, mixed conifer-alpine, and alpine. Eighty-nine bird species were observed. The total number of birds and bird species followed a skewed bell-shaped distribution. Some birds were quite narrow in their choice of vegetative zones while others showed very little selectivity. Both total number of individual birds and bird species appeared to reach highest values in study plots with a substantial component of mountain big sagebrush.
