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.

Bird counts in stands of big sagebrush and greasewood

Publications Posted on: May 12, 2016
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.

Seeding big sagebrush successfully on Intermountain rangelands

Publications Posted on: January 12, 2016
Big sagebrush can be seeded successfully on climatically suitable sites in the Great Basin using the proper seeding guidelines. These guidelines include using sufficient quantities of high-quality seed of the correct subspecies and ecotype, seeding in late fall to mid-winter, making sure that the seed is not planted too deeply, and seeding into an environment with reduced competition.

Establishing big sagebrush and other shrubs from planting stock

Publications Posted on: October 06, 2015
Bareroot or container seedlings can be used to quickly re-establish big sagebrush and other native shrubs in situations where direct seeding is not feasible or unlikely to succeed. Guidelines are provided for developing a planting plan and timeline, arranging for seedling production, and installing and managing outplantings.

Insights into transcriptomes of Big and Low sagebrush

Publications Posted on: August 12, 2015
We report the sequencing and assembly of three transcriptomes from Big (Artemisia tridentatassp. wyomingensis and A. tridentatassp. tridentata) and Low (A. arbuscula ssp. arbuscula) sagebrush. The sequence reads are available in the Sequence Read Archive of NCBI. We demonstrate the utilities of these transcriptomes for gene discovery and phylogenomic analysis.

Fire rehabilitation using native and introduced species: A landscape trial

Publications Posted on: March 26, 2015
rehabilitation study comparing a predominately introduced species seed mix used by the US Department of Interior-Bureau of Land Management (BLM), a mix of native and introduced species provided by the US Department of Agriculture-Agricultural Research Service (ARS), and 2 native seed mixes (high and low diversity). Mixes were seeded with a rangeland drill on the big sagebrush (Artemisia tridentata var. wyomingensis [Beetle & A.
