In this study, Frank and McNaughton tested the theory that herbivory would stimulate above-ground production by measuring the effects of elk (Cervus elaphus) and bison (Bison bison) grazing on plant production in Yellowstone National Park. The temporal grazing patterns among study sites within the park suggested that elk and bison were utilizing forage during its growing season when reductions in plant biomass could be compensated for by further growth. The authors found that production in grazed areas was 48% greater on average than production in grazing exclosures. This study provides evidence to support the theory that herbivory stimulates above-ground production in the grasslands of Yellowstone National Park.
