A prairie dog stands on alert. The USGS National Wildlife Health Center works to identify, track, and prevent wildlife disease. Better protection of prairie dogs against plague would minimize the risk of disease transfer to endangered black-footed ferrets, aid in prairie dog conservation, and protect public health.

Creosote bush shrublands are one of the driest Sonoran Desert plant communities; the creosote bush and white ratany are the dominant plants; a USGS study showed that their coverage is likely to decrease with forecasted climate change because of less winter precipitation and more aridity.
