Effects of Short-Term Cattle Exclusion on Plant Community Composition: Prairie Dog and Ecological Site InfluencesOn the Ground • Maintaining cattle and prairie dogs on rangelands is important ecologically, economically, and culturally. However, competition between these species, both actual and perceived, has led to conflict. • We explored the effects of short-term (2-year) cattle exclusion on plant communities both on and off prairie dog towns and among three common ecological sites. • Plant communities were different between on-town and off-town plots and among ecological sites but were similar between cattle-excluded and nonexcluded plots. • Plant community composition did not differ between rangeland targeted for moderate forage utilization and that in which cattle had been excluded for 2 years.
History of Occurrence and Present Home Territory Sizes for Black-Tailed Prairie Dogs on the Standing Rock Sioux ReservationOn 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.
Use of Ecological Sites in Managing Wildlife and Livestock: An Example with Prairie DogsOn the Ground • The perception of prairie dogs among Native Americans living on the Standing Rock Sioux Reservation is mixed. Some Native Americans focus on the loss of forage productivity, whereas others are interested in the cultural and ecological aspects of prairie dogs. • The use of ecological sites may provide a mechanism for developing a management framework that would consider both livestock and prairie dogs. • The three ecological sites we surveyed had large differences in off-colony standing crop, but in 2 of the 3 years we surveyed, there were no differences between standing crop on-colony. • This suggests that management of prairie dogs on rangelands should focus on limiting prairie dogs on more productive ecological sites with less productive sites receiving less emphasis.
