GREATER SAGE-GROUSE IN A GRAZED LANDSCAPE: HABITAT SELECTION, DEMOGRAPHIC RATES, AND POPULATION TRENDS IN CENTRAL MONTANA

, 2023
Greater sage-grouse (Centrocercus urophasianus) abundance has declined across the species’ range due to habitat loss, degradation, and fragmentation. To address this decline, information is needed to guide habitat conservation priorities and population ...

Bespoke design of cage trap and patagial wing tag for the capture and study of black grouse Lyrurus tetrix at lek sites: assessment of effectiveness for future studies

Given new avenues for Black Grouse Lyrurus tetrix telemetry, and translocations to previously occupied areas, we designed a new cage trap for use at leks that was safe, reliable, and easily transportable, and a custom black-and-white wing-tag that was ...

Ecology and Management of Columbian sharp-tailed grouse in Southern Idaho: Evaluating infrared technology, the Conservation Reserve Program, statistical population reconstruction, and the olfactory concealment theory

, 2014
Wildlife biologists often use counts of individual birds attending leks to monitor several grouse species, but we lack a standard method for counting Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus; CSTG) on leks.

Using Remote Camera Technology to Survey Sharp-Tailed Grouse Leks in Montana

, 2016
Some of the biggest challenges in conducting lek surveys for sharp-tailed grouse in Montana are weather-related road access, distance between leks, visibility, and determining the maximum number of males and females at the lek. The optimum time to survey

Response of a Sage Grouse Breeding Population to Fire in Southeastern Idaho

, 2000
Prescribed burning is a common method to eliminate sagebrush (Artemisia spp.) and has been suggested as a tool to enhance the habitat of sage grouse (Centrocercus urophasianus).
