Results showed higher predation on colonies than off for artificial nests, but a small sample of natural nests showed no differences. We will also report results from 1996-97 studies that compared plant structure, avian abundance, and plant species composition on and off prairie dog colonies. Monitored wintering raptors on and off prairie dog colonies, and other areas, in eastern Colorado during the 1997-98 winter. In future years this project will be expanded to surrounding States to evaluate long-term regional trends in raptor populations that winter on or near prairie dog colonies. Biggins et al.
Study is still in progress.
This BIN is now completed except for publications. Steve Cinnamon earlier indicated that the proximate concern involved a site at Fort Larned, Kansas. The Santa Fe Trail passes through the area and is designated as a historical site. Prairie dogs live at the site, and their burrowing activities are degrading the trail ruts. NPS is interested in relocating prairie dogs off-site.
