Sage-grouse & Sagebrush Ecosystem


USGS has been a leader in sagebrush ecosystem research and continues to meet the priority science needs of management agencies. We bring a diversity of expertise and capabilities to address a wide variety of science needs at multiple spatial scales and are committed to providing high quality science to our management partners.

When Unchecked, Free-Roaming Horse Populations Threaten Greater Sage-Grouse

Greater sage-grouse populations may decline by more than 70% within free-roaming horse-occupied areas by 2034 if horse populations increase unchecked at current rates. Reducing horse numbers could neutralize their negative impacts.

New Research Highlights Decline of Greater Sage-Grouse in the American West, Provides Roadmap to Aid Conservation

RESTON, Va. – Greater sage-grouse populations have declined significantly over the last six decades, with an 80% rangewide decline since 1965 and a nearly 40% decline since 2002, according to a new report by the U.S. Geological Survey. Although the overall trend clearly shows continued population declines over the entire range of the species, rates of change vary regionally.

Weather affects post‐fire recovery of sagebrush‐steppe communities and model transferability among sites

Altered climate, including weather extremes, can cause major shifts in vegetative recovery after disturbances. Predictive models that can identify the separate and combined temporal effects of disturbance and weather on plant communities and that are transferable among sites are needed to guide vulnerability assessments and management...

A chemical and bio‐herbicide mixture increased exotic invaders, both targeted and non‐targeted, across a diversely invaded landscape after fire

QuestionsInvasive‐plant treatments often target a single or few species, but many landscapes are diversely invaded. Exotic annual grasses (EAGs) increase wildfires and degrade native perennial plant communities in cold‐desert rangelands, and herbicides are thus sprayed to inhibit EAG germination and establishment. We asked how EAG target and non‐...

Sagebrush conservation strategy—Challenges to sagebrush conservation

The sagebrush (Artemisia spp.) biome, its wildlife, and the services and benefits it provides people and local communities are at risk. Development in the sagebrush biome, for many purposes, has resulted in multiple and often cumulative negative impacts. These impacts, ranging from simple habitat loss to complex, interactive changes in ecosystem...
