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 yea rs (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(More)
