Response of a small population of greater sage-grouse to tree removal: implications of limiting factors

Human-Wildlife Interactions, 2017
In Utah, greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) range has been reduced to 50% of what is considered historical availability due to habitat degradation and loss. In an effort to improve sage-grouse habitat in southern Utah,

Songbird population trajectories diverge under simulations of conifer encroachment versus removal in a sagebrush ecosystem. [PDF]

Ecol Appl
Abstract Woody plant encroachment into grasslands and shrublands is a global phenomenon that negatively impacts ecosystem services and wildlife populations. North American sagebrush ecosystems have experienced widespread degradation from encroaching conifers, leading to losses of sagebrush‐obligate wildlife.

Using spatial statistics and point‐pattern simulations to assess the spatial dependency between greater sage‐grouse and anthropogenic features

Wildlife Society Bulletin, 2013
The greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse), a candidate species for listing under the Endangered Species Act, has experienced population declines across its range in the sagebrush (Artemisia spp.) steppe ecosystems of ...

A spatially explicit modeling framework to guide management of subsidized avian predator densities

Ecosphere, 2023
Anthropogenic resource subsidization across western ecosystems has contributed to widespread increases in generalist avian predators, including common ravens (Corvus corax; hereafter, raven).

Timing of Vegetation Sampling at Greater Sage-Grouse Nests [PDF]

Rangeland Ecology & Management, 2005
Habitat management guidelines for greater sage-grouse, Centrocercus urophasianus, have been formulated, in part, based on studies of nest site selection. However, these guidelines may not represent conditions when the female initiates nesting because sampling occurs posthatch (> 30 days after nest initiation) to avoid disturbing incubating females ...

Seasonal movements of greater sage‐grouse populations in Utah: Implications for species conservation

Wildlife Society Bulletin, 2016
Greater sage‐grouse (Centrocercus urophasianus; sage‐grouse) is considered an umbrella species for sagebrush (Artemisia spp.) landscapes in western North America. In 2015, the U.S.

Stakeholder contemporary knowledge needs regarding the potential effects of tall structures on sage-grouse

Human-Wildlife Interactions, 2017
The U.S. Energy Policy Act of 2005 required all state and federal agencies to grant utilities access permits to promote reliable, renewable energy production and transmission. Contemporary transmission relies largely on above-ground electric transmission

The performance of drones and artificial intelligence for monitoring sage‐grouse at leks

Wildlife Biology, EarlyView.
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

Courtship display behavior influences tail myology in Centrocercus minimus (Gunnison sage‐grouse)

Journal of Anatomy, EarlyView.
Courtship displays among birds are widespread, particularly those which incorporate raised tail feathers for extended periods of time. The Gunnison sage‐grouse (Centrocercus minimus) is such a species. When we compared the tail muscles of the sage‐grouse to birds which do not engage in erected tail fan postures, both morphology proportional mass ...
