Abstract
On the Ground Past management and historic occupation by black-tailed prairie dogs will affect the vegetation responses to changes in management. Ecological sites have different production potential and may influence colonization by black-tailed prairie dogs. Thin Claypan ecological sites had the largest coterie home territory size at 1.8 ha but also had coteries among the smallest at 0.5 ha.
Highlights
Our purpose in this paper is to introduce the reader of this special issue of Rangelands to the historic and present populations of prairie dogs at the Standing Rock Sioux Reservation research site and to describe the present coterie home territory sizes among a few different ecological sites
Coterie home territory size was estimated at eight sites currently being used as part of a study evaluating the effects of herbivory on plant community composition.[8]
Because of the limited availability of historic photographs, our estimate of area occupied by prairie dogs was restricted to what is defined as pasture 1 and portions of pasture 2
Summary
Past management and historic occupation by black-tailed prairie dogs will affect the vegetation responses to changes in management. Previous studies have evaluated the sizes of coterie home territories across the Northern Great Plains, but none to our knowledge has considered ecological sites.[2] Our purpose in this paper is to introduce the reader of this special issue of Rangelands to the historic and present populations of prairie dogs at the Standing Rock Sioux Reservation research site and to describe the present coterie home territory sizes among a few different ecological sites. Coterie home territory size was estimated at eight sites currently being used as part of a study evaluating the effects of herbivory (cattle and prairie dogs) on plant community composition (see Field et al in this issue).[8] Sites were originally selected on the basis of ecological site, landscape position, and aspect. Known locations were marked on handheld GPS units and transferred to ArcMap 10 and used to create minimum convex polygons for each coterie
