Detailed Description
Mean predicted pinyon jay (Gymnorhinus cyanocephalus) density (birds/km2) in 2008 (left) and 2020 (right) based on Bayesian hierarchical models accounting for incomplete detection. Gray polygon borders represent priority areas for conservation (PACs; U.S. Fish and Wildlife Service 2013) for greater sage-grouse (Centrocercus urophasianus). The model was informed by point counts conducted from 2008 – 2020; USA. 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...
