Mean predicted change in pinyon jay (Gymnorhinus cyanocephalus) density (birds/km2) from 2008 to 2020
By Fort Collins Science Center
April 2023 (approx.)
Detailed Description
Mean predicted change in pinyon jay (Gymnorhinus cyanocephalus) density (birds/km2) from 2008 to 2020 based on Bayesian hierarchical models accounting for incomplete detection. The model was informed by point counts conducted from 2008 to 2020; USA. Gray polygon borders represent priority areas for conservation (PACs) for greater sage-grouse (Centrocercus urophasianus). Darker blue color indicates reduced pinyon jay density from 2008 to 2020, and darker red color indicates increased pinyon jay density from 2008 to 2020. Base map modified from National Weather Service, 1:2,000,000, 1980 digital data.

Modeling Songbird Density-Habitat Relationships to Predict Population Responses to Environmental Change Within Pinyon-juniper and Sagebrush Ecosystems
Within areas of overlapping sagebrush and pinyon-juniper ecosystems, wildlife populations are declining due to habitat fragmentation and degradation, changing environments, and human development. However, management to bolster species associated with one ecosystem may result in negative consequences for species associated with the other. Thus, land managers are challenged with balancing which...
