Book Description
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.

Book Description
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.

Book Description
This book is about the status and future of the sagebrush ecosystem and its dependent species. The ecosystem is not healthy and is diminishing due to the many and various human land uses. Maintaining the ecosystem will require monumental changes in management and those changes must address all land uses in an integrated, holistic manner to be effective. The two major obstacles are a lack of needed resources, both funds and land use direction, and the attempt to stop the loss and degradation of sagebrush habitats while lacking essential research information on which to base effective strategies.

Book Description
Singing Grass, Burning Sage is a celebration in photos and text of eastern Washington's arid lands--a region that encompasses the heart of the Columbia River Basin, and supports a shrub-steppe environment dominated by sagebrush and bunchgrass. Formed by massive basalt flows that pulsed across the Basin, sculpted by ceaseless winds, and scoured by the cataclysmic Lake Missoula floods at the climax of our most recent Ice Age, this landscape offers some of the most spectacular geologic vistas in the world. The vast spaces of this wide domain are full of wonder and surprise, as that raw rock provides the setting for a dramatic interplay of human and natural history.
