The influence of floods and herbivory on cottonwood establishment and growth in Yellowstone National Park
Abstract Herbivory by ungulates can shape the structure and function of riparian forests. However, our understanding of the interactions between herbivores and cottonwoods ( Populus spp.) is largely derived from studies of domestic livestock grazing and may not reflect free ranging herds of wild ung...

Over 92% of the cottonwoods occurred along the Lamar River, and recruitment along this river appears to follow infrequent large peak flows. Soda Butte Creek and the Gardner River cottonwoods exhibited nearly annual recruitment. The resulting cottonwood biomass from the flooding events has exceeded herbivore demand. Even at relatively low consumption rates, bison are able to remove a significant proportion of total cottonwood production in the study areas limiting plant height and forage available to wintering elk. We conclude that the large cottonwood recruitment event that began in the late 1990s was due to a rare series of large snowmelt‐driven floods.
