Bird counts in stands of big sagebrush and greasewood

Publications Posted on: June 22, 2020
Total numbers of birds and numbers of bird species were significantly (p=0.05 percent) higher in stands of big sagebrush than in stands of greasewood. This was especially true for Brewer’s sparrow, lark sparrow, and mourning dove. The big sagebrush ecosystem appears to support greater number of birds and more species of birds than does the greasewood ecosystem.

Genotype, soil type, and locale effects on reciprocal transplant vigor, endophyte growth, and microbial functional diversity of a narrow sagebrush hybrid zone in Salt Creek Canyon, Utah

Publications Posted on: March 04, 2020
When addressing the nature of ecological adaptation and environmental factors limiting population ranges and contributing to speciation, it is important to consider not only the plant's genotype and its response to the environment, but also any close interactions that it has with other organisms, specifically, symbiotic microorganisms.

Challenges of establishing big sagebrush (Artemisia tridentata) in rangeland restoration: effects of herbicide, mowing, whole-community seeding, and sagebrush seed sources

Publications Posted on: October 02, 2019
The loss of big sagebrush (Artemisia tridentata Nutt.) on sites disturbed by fire has motivated restoration seeding and planting efforts. However, the resulting sagebrush establishment is often lower than desired, especially in dry areas. Sagebrush establishment may be increased by addressing factors such as seed source and condition or management of the plant community.

Getting climate-smart with seeds: How a new software tool helps prepare landscapes for expected future conditions

Pages Posted on: August 06, 2019
Sagebrush ecosystems are a major component of western U.S. landscapes and they provide vital habitat to a wide array of wildlife species, including greater sage-grouse and pygmy rabbits. However, in recent decades, sagebrush ecosystems have been reduced or degraded by a wide range of disturbances, including human development, overgrazing, severe fires, and encroachment by cheatgrass and pinyon-juniper woodlands. These factors are expected to continue or worsen with anticipated climate change.

Sage advice for managers: A new, collaborative science framework for conservation and restoration of the sagebrush biome

Pages Posted on: April 26, 2019
The two-part Science Framework for Conservation and Restoration of the Sagebrush Biome published by the U.S. Forest Service Rocky Mountain Research Station is a new, multi-scale approach to management of sagebrush ecosystems. The product of an extensive collaboration between State and Federal agencies and universities, it employs science on ecological resilience to disturbance and resistance to invasive species (like cheatgrass), along with Greater sage-grouse habitat requirements, to improve conservation planning and help prioritize management actions.

Vegetation dynamics at the woodland-shrubland interface: Role of climate, disturbance, and species interactions

Publications Posted on: October 05, 2018
The boundary between woodlands and shrublands delineates the distribution of the tree biome in many regions across the globe. Woodlands and shrublands interface at multiple spatial scales, and many ecological processes operate at different spatial scales to determine the position of the woodland-shrubland boundary.

A science-based framework to develop effective management strategies for addressing threats to sagebrush ecosystems and sage-grouse

FS News Posted on: November 29, 2016
The report, Using Resilience and Resistance Concepts to Manage Threats to Sagebrush Ecosystems, Gunnison Sage-Grouse, and Greater Sage-Grouse in Their Eastern Range: A Strategic Multi-Scale Approach, allows managers to predict how sagebrush ecosystems will respond to both disturbance and management actions in areas that support sage-grouse. Using this approach, managers can better assess habitat threats, target areas for treatment, and develop appropriate management strategies.

Research helps conserve and restore shrub dominated ecosystems

Science Spotlights Posted on: October 14, 2016
Two common gardens were established for big sagebrush and blackbrush at the Great Basin and Desert Experimental Ranges in Utah, respectively. The experimental areas are ideal for studies in which plants representing multiple populations of a single species are grown together in common environments. These types of studies provide a useful approach for understanding species limits.  

Reseeding big sagebrush: Techniques and issues

Publications Posted on: May 12, 2016
Reestablishing big sagebrush on rangelands now dominated by native perennial grasses, introduced perennial grasses, or exotic annual grasses, particularly cheatgrass (Bromus tectorum), serves to stabilize soil, improve moisture availability and nutrient recyling, increase biological diversity, and foster community stability and resiliency.

Sage-grouse habitat restoration symposium proceedings

Publications Posted on: May 12, 2016
Declines in habitat of greater sage-grouse and Gunnison sage-grouse across the western United States are related to degradation, loss, and fragmentation of sagebrush ecosystems resulting from development of agricultural lands, grazing practices, changes in wildfire regimes, increased spread of invasive species, gas and oil development, and other human impacts.
