Multi-scale Statewide Wyoming Greater Sage-grouse Trends Determined by Population Viability Analysis Completed
USGS scientists and partners investigated sage-grouse population trends in Wyoming and at multiple spatial scales.
To evaluate greater sage-grouse populations in Wyoming, a stronghold for the species, USGS researchers and colleagues investigated population trends statewide and at multiple spatial scales across existing management units. They incorporated lek count data in a population viability analysis across five geographic scales (cluster levels) to determine the finite rate of population change during the period 1993–2015. This approach can identify clusters that are out of sync with surrounding populations and help identify the influence of local trends on larger scale population trajectories. This can provide new insight into management decisions that may help conserve populations across broad landscapes.
