WOLVES AND RECOVERY OF RIPARIAN TREES IN YELLOWSTONE
FIGURE 4.10 Wolf reintroduction is fostering cottonwood and willow reproduction and growth in Yellowstone National Park. Shown here are the results of successful establishment and growth of young cottonwoods (the smaller, densely spaced saplings under the mature cottonwood trees) in a riverside area along the Lamar River, where the local topography and the presence of wolves have reduced feeding by elk and bison.
