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,

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.

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 ...

Declining populations of greater sage-grouse: where and why

Human-Wildlife Interactions, 2017
Scientists have been predicting the extinction of greater sage-grouse (Centrocercus urophasianus) since 1916, and sage-grouse populations have declined relentlessly during the last century despite attempts to reverse the decline. In this review paper, we

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).

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.

Is Diet Selection by Greater Sage-Grouse Influenced by Biomass Availability or Toxins? [PDF]

, 2016
Foraging herbivores must meet nutritional requirements by not only finding enough plant biomass to consume, but also finding plants with high protein content and low concentrations of potentially toxic plant secondary metabolites (PSMs).

Development of optimized methods for unbiased dusky grouse population monitoring using real and simulated data

Wildlife Biology, EarlyView.
Rigorous state‐wide monitoring programs are lacking for dusky grouse Dendragapus obscurus, a North American species of forest grouse with relatively low detectability that is found in coniferous and mountainous areas in the western United States and Canada.
