Wildfire probability estimated from recent climate and fine fuels across the big sagebrush region Open
Background Wildfire is a major proximate cause of historical and ongoing losses of intact big sagebrush ( Artemisia tridentata Nutt.) plant communities and declines in sagebrush obligate wildlife species. In recent decades, fire return int…

A Spatial Prioritization of Conifer Management to Defend and Grow Sagebrush Cores Open
Sagebrush ecosystems across the western U.S. are in decline due to numerous threats, including expansion of coniferous woodlands and forests. The interagency Sagebrush Conservation Design effort recently quantified sagebrush ecological int…

Grassland intactness outcompetes species as a more efficient surrogate in conservation design Open
Mapped representations of species−habitat relationships often underlie approaches to prioritize area‐based conservation strategies to meet conservation goals for biodiversity. Generally a single surrogate species is used to inform conserva…

Combining resilience and resistance with threat‐based approaches for prioritizing management actions in sagebrush ecosystems Open
The sagebrush biome is a dryland region in the western United States experiencing rapid transformations to novel ecological states. Threat‐based approaches for managing anthropogenic and ecosystem threats have recently become prominent, bu…

Regional Context for Balancing Sagebrush- and Woodland-Dependent Songbird Needs with Targeted Pinyon-Juniper Management Open
In the western United States, pinyon-juniper woodlands have expanded by as much as sixfold among sagebrush landscapes since the late 19th century, with demonstrated negative impacts to the behavior, demography, and population dynamics of s…

A targeted annual warning system developed for the conservation of a sagebrush indicator species Open
A fundamental goal of population ecologists is to identify drivers responsible for temporal variation in abundance. Understanding whether variation is associated with environmental stochasticity or anthropogenic disturbances, which are mor…

The ties that bind the sagebrush biome: integrating genetic connectivity into range-wide conservation of greater sage-grouse Open
Conserving genetic connectivity is fundamental to species persistence, yet rarely is made actionable into spatial planning for imperilled species. Climate change and habitat degradation have added urgency to embrace connectivity into netwo…

Using Virtual Fencing to Create Fuel Breaks in the Sagebrush Steppe Open
Wildfires are increasingly impacting ecosystem processes and ecological services provided by sagebrush rangelands in the western United States. Mitigating this problem involves actions taken before, during, and after fire. In recent years,…

Optimizing targeting of pinyon-juniper management for sagebrush birds of conservation concern while avoiding imperiled pinyon jay Open
Contemporary restoration and management of sagebrush-dominated ( Artemisia spp.) ecosystems across the intermountain west of the United States increasingly involves the removal of expanding conifer, particularly juniper ( Juniperus spp.) a…

Regional context for balancing sagebrush- and woodland-dependent songbird needs with targeted pinyon-juniper management in the sagebrush biome Open
Tree expansion among historic grassland and shrubland systems is a global phenomenon, which results in dramatic influences on ecosystem processes and wildlife populations. In the western US, pinyon-juniper woodlands have expanded by as muc…
View article: Virtual Fencing Effectively Excludes Cattle from Burned Sagebrush Steppe
Virtual Fencing Effectively Excludes Cattle from Burned Sagebrush Steppe Open
On public lands grazing allotments in the western US sagebrush steppe, cattle are generally excluded from burned pastures for 2 yr post fire. If only a portion of a pasture burns, the burned area may be fenced, allowing for cattle grazing …

Threat‐Based State and Transition Models Predict Sage‐Grouse Occurrence while Promoting Landscape Conservation Open
A recent collaboration between federal, state and private partners in southeast Oregon developed mental models to distill complex plant‐based community ecology for management. The mental models were then turned into a simplified, habitat‐c…

Quantifying functional connectivity: The role of breeding habitat, abundance, and landscape features on range‐wide gene flow in sage‐grouse Open
Functional connectivity, quantified using landscape genetics, can inform conservation through the identification of factors linking genetic structure to landscape mechanisms. We used breeding habitat metrics, landscape attributes, and indi…

Understanding biological effectiveness before scaling up range‐wide restoration investments for Gunnison sage‐grouse Open
Imperiled species recovery is a high‐stakes endeavor where uncertainty surrounding effectiveness of conservation actions can be an impediment to implementation at necessary scales, especially where habitat restoration is required. Gunnison…
