Herbivory by native ungulates, primarily elk (Cervus elaphus), was studied on xeric, bunchgrass-dominated slopes on the northern ungulate winter range of Yellowstone National Park. Plant cover, standing green biomass, and nutrient concentrations were compared between grassland sites protected from grazing for 24-27 years and adjacent plots grazed mostly during winter by elk, and to some extent by bison (Bison bison). Accumulated litter and standing dead vegetation were four times more abundant on the ungrazed plots. However, few consistent differences were observed in grass or forb biomass from elk herbivory. There was no overall effect of grazing treatment on forbs or other nongrasses (P0.05). Total grass biomass was less on grazed than ungrazed sites in 1986, after a dry, warm spring, but there was no difference in 1987 (P0.05). Biomass of junegrass (Koeleria macrantha) and thickspiked wheatgrass (Agropyron dasystachyum) was greater on grazed than ungrazed sites. Three nongrasses (Artemisia frigida, Phlox hoodii, Antennaria microphylla) were more abundant on ungrazed sites although the effect on grazing treatment was not significant (P0.05). The number of grasses ( = 4.5), forb (17.5), and shrub ( = 3.5) species did not differ between grazed and ungrazed plots (P

Wagner, one of our most distinguished wildlife biologists, is a strong critic of ecological practices in the national parks. This book provides an assessment of the ecological history of Yellowstone's northern range, since before the park existed, showing the impact of US Park Service policies on the health of the areas they oversee. He demonstrates that elk had been historically rare throughout the region and that overgrazing by elk has seriously degraded the landscape and altered the structure of the area. This is a major contribution to reconstructing the ecology of this region over the course of the past 500 years. It is also a critique of US Park Service management policies and their stewardship of the nation's most cherished natural areas. Wagner's book will generate substantial attention and debate both in the scientific and policy/management communities.
