Field guide to Nevada grasses (pp. 256)

There are more than 100 species of range grasses in the mountains and valleys of Nevada's Great Basin, and the author describes them in both technical and practical language. All grasses are illustrated in color with explanations given as to the various parts of the grass plant and their locations on the landscape.

Wyoming Big Sagebrush State & Transition Model And Management Key for Nevada First Approximation

During the late twentieth century, public perception of Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) [Beetle & A. Young] changed from being a ‘weed’ to a valuable resource in danger of extirpation in some landscapes. The two polar perspectives, perceiving it to be of no value and only competitive with grasses, or perceiving it to be so valuable and scarce that we must never control it, neither serve or benefit land managers or the wildlife that depend on this important habitat. During this period, a focus on rangeland condition has shifted to a focus on ecological thresholds and the information needed to allocate limited financial and other resources to those areas, times, and actions that are most important for maintaining rangeland health.

Fact Sheets
Nutritional Properties of Windrowed and Standing Basin Wildrye over Time
Many Nevada farmers and ranchers are in constant search of economical, high- producing winter forages for their beef cattle production system. An often overlooked forage but one that is common in Nevada and the Intermountain West is basin wildrye (Leymus cinereus).

Viewpoint: An alternative Management Paradigm for Plant Communities Affected by Invasive Annual Grasses in the Intermountain West
Today’s landscapes are not those described in 1860. With over 400,000 km2 colonized by cheatgrass (Bromus tectorum) and other annual grasses, we believe it is time to declare: The pristine-management-paradigm has failed. Continued, wholesale application of this concept is misguided.

Case Study: Reducing cheatgrass (Bromus tectorum L.) fuel loads using fall cattle grazing.
Wildfire is a major concern in the Intermountain West. Fuels management can lower the potential for negative wildfire effects. Cheatgrass (Bromus tectorum L.), an exotic annual grass, invasion has resulted in a buildup of highly flammable fine fuels that promote frequent wildfire. Removal of cheatgrass standing crop...
