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

Common Ravens Disrupt Greater Sage-grouse Lekking Behavior in the Great Basin, USA [PDF]

, 2021
Expansion of human enterprise has contributed to increased abundance and distribution of common ravens (Corvus corax; ravens) across sagebrush (Artemisia spp.) ecosystems within western North America. Ravens are highly effective nest predators of greater

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).

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

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).

Greater Sage-Grouse (Centrocercus Urophasianus) Select Habitat Based on Avian Predators, Landscape Composition, and Anthropogenic Features [PDF]

, 2014
Prey species minimize the risk of predation directly by avoiding predators and indirectly by avoiding risky habitat. Habitat loss and fragmentation have been prevalent in Greater Sage-Grouse (Centrocercus urophasianus; hereafter “sage-grouse”) habitat ...

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.

Greater Sage-Grouse Brood Responses to Livestock Grazing in Sagebrush Rangelands [PDF]

, 2022
The distribution and abundance of the greater sage-grouse (Centrocercus urophasianus; sage-grouse) have declined in the last 60 years. Range contractions and population declines have been attributed to loss and fragmentation of their sagebrush (Artemisia
