Modeling the Potential Habitat Gained by Planting Sagebrush in Burned Landscapes

Conservation
Many revegetation projects are intended to benefit wildlife species. Yet, there are few a priori evaluations that assess the potential efficiency of restoration actions in recovering wildlife habitats.

A draft genome provides hypotheses on drought tolerance in a keystone plant species in Western North America threatened by climate change

Ecology and Evolution, 2021
Climate change presents distinct ecological and physiological challenges to plants as extreme climate events become more common. Understanding how species have adapted to drought, especially ecologically important nonmodel organisms, will be crucial to ...

Fire regime shift reveals 17th century socio‐ecological change in the Rio Grande del Norte National Monument, New Mexico

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Humans have influenced ecosystems for millennia, and social changes can have notable ecological effects. Recent human influence on ecosystems is exemplified by the collapse of fire regimes circa 1900 in the western United States due to increased grazing, fire suppression, and declining Indigenous fire use.

Relative abundance of and composition within fungal orders differ between cheatgrass (Bromus tectorum) and sagebrush (Artemisia tridentate)-associated soils.

PLoS ONE, 2015
Nonnative Bromus tectorum (cheatgrass) is decimating sagebrush steppe, one of the largest ecosystems in the Western United States, and is causing regional-scale shifts in the predominant plant-fungal interactions.

Integrating Ecosystem Resilience and Resistance Into Decision Support Tools for Multi-Scale Population Management of a Sagebrush Indicator Species

Frontiers in Ecology and Evolution, 2020
Imperiled sagebrush (Artemisia spp.) ecosystems of western North America are experiencing unprecedented conservation planning efforts. Advances in decision-support tools operationalize concepts of ecosystem resilience by quantitatively linking spatially ...

Integrating multi‐decadal satellite imagery and species distribution models for conservation planning in oak woodlands

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Oak woodlands are among California's least protected yet most ecologically important ecosystems, providing critical habitat for a wide variety of plant and animal species. These foundational plant communities are increasingly threatened by drought, wildfire, and other climate‐driven disturbances, which have contributed to significant declines ...

Growth and age dynamics of juvenile plants of a dominant shrub in North American drylands

Ecosphere
Long‐lived perennial species in drylands tolerate a range of environmental conditions over their lifespan, but young plants are more vulnerable to stressful conditions than mature plants.

Field research guided by citizen science and monitoring data reveal a novel alpine breeding distribution and vegetation associations of a declining, habitat-specialist songbird in Colorado, USA

Avian Conservation and Ecology
Documenting the breeding habitat and distribution of migratory songbirds is essential for accurately assessing their conservation status. The “sagebrush” subspecies of the Brewer’s Sparrow ( Spizella breweri breweri ) breeds in greatest abundance in ...

Effects of wildfire on the distribution of mammals and birds in a working shrub‐steppe landscape

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The intensity, frequency, and extent of wildfire have increased drastically in the sagebrush (Artemisia spp.) ecoregion within Washington, USA, over the last few decades. Wildfire on this landscape, already modified and fragmented by agriculture and other disturbances, may challenge the persistence of wildlife that depend on continuous ...
