Your question is a good one because it seeks a cultural practice to reduce prairie dog populations through habitat modification.
Black-tailed prairie dogs avoid (usually) sage brush, three-awn, prairiedog weed, and horseweed. Beyond that, we are not aware of more specific research. We would suggest searching our Digital Commons database digitalcommons.unl.edu/icwdm/. It presently houses over 1,800 articles (and continues to grow) that can be searched.
