White-Tailed Deer (Odocoileus Virginianus Zimmermann) Browsing Effects On Quality Of Tallgrass Prairie Community Forbs, Roger C. Anderson, Debra Nelson, M. Rebecca Anderson, Marcia A. Rickey
Proceedings of the North American Prairie Conferences
We examined the effect of white~tailed deer (Odocoiieus virginianus Zimmermann) browsing on community quality of tallgrass prairie forbs at a site in northeastern Illinois over a period of ten years (1992- 2001). Deer densities in the study area varied from 32- 50 km-2 (83- 130 deer mi-2) between 1992 and 1997 and declined to 7- 9 km-2 (18- 23 mi-2) following initiation of hunting. In a plot protected from deer browsing, abundances of browse-sensitive species increased and unpreferred and browse~tolerant species decreased. Community quality of forbs measured with a new index, Weighted Mean …

The 92 ha Cottonwood Lake Study Area is located in south-central North Dakota along the eastern edge of a glacial stagnation moraine known as the Missouri Coteau. The study area has been the focus of biological and hydrological research since the U. S. Fish and Wildlife Service purchased the site in 1963. We studied the plant communities of the Cottonwood Lake Study Area from 1992 to 2001. During this time period, the vascular flora of the study area consisted of 220 species representing 52 families. Over half of the species were perennial forbs (117 species). Perennial grasses (26 species) and …
