Maximizing the detection probabilities of dusky grouse for population monitoring

Wildlife Biology, EarlyView.
Despite its status as a game species in the western USA, rigorous monitoring of dusky grouse Dendragapus obscurus populations is limited. Obtaining an adequate number of observations for effective population monitoring of dusky grouse is challenging due to difficult‐to‐reach montane habitats, cryptic behaviors, and limited personnel, time, and funds at

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.

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.

Mapping sage‐grouse fence‐collision risk: Spatially explicit models for targeting conservation implementation

Wildlife Society Bulletin, 2013
Recent research suggested greater sage‐grouse (Centrocercus urophasianus; hereafter, sage‐grouse) fence collision may be widespread, and fence‐marking methods have been developed for reducing prairie‐grouse collision in sagebrush‐steppe habitats. However,

Abundance and occupancy trends of sooty grouse in western Oregon: determining best modeling practices by comparing observed and simulated data

Wildlife Biology, EarlyView.
Sooty grouse Dendragapus fuliginosus are large game birds that occupy montane forests in the Pacific Northwest, USA. These forests have been altered by human activities, which have been shown to have both positive and negative impacts on local populations.

Better living through conifer removal: A demographic analysis of sage-grouse vital rates. [PDF]

PLoS ONE, 2017
Sagebrush (Artemisia spp.) obligate wildlife species such as the imperiled greater sage-grouse (Centrocercus urophasianus) face numerous threats including altered ecosystem processes that have led to conifer expansion into shrub-steppe.

Greater sage‐grouse dynamics are influenced by winter temperature rather than indices of grazing, drought, and breeding season weather in a northern Great Plains population

Conservation Science and Practice, EarlyView.
We evaluated the impacts of grazing, climatic variability, and vegetation productivity on the population dynamics of a northern Great Plains greater sage‐grouse population. We found winter temperature influenced annual population growth rates, but did not detect influences of drought, breeding season weather, vegetation productivity or short‐term ...

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 ...

Adult sage‐grouse numbers rise following raven removal or an increase in precipitation

Wildlife Society Bulletin, 2017
Weather and lethal control of common ravens (Corvus corax; hereafter, ravens) can affect the nesting success of greater sage‐grouse (Centrocercus urophasianus), but implications of these effects in terms of the subsequent size of the breeding population ...

Integrating herbicide application and seeding techniques to restore native plant diversity in crested wheatgrass‐dominated rangelands

Restoration Ecology, EarlyView.
Abstract Introduction Restoring native plant diversity in crested wheatgrass (Agropyron cristatum)‐dominated rangelands is a persistent challenge in ecological restoration across western North America. Dense, long‐lived stands of this exotic grass suppress native seedling recruitment, hinder habitat restoration, and reduce ecosystem resilience ...
