– Indian legends of ravens following wolves are true-they do follow them because wolves mean food –
When the grey wolf was reintroduced into the Greater Yellowstone Ecosystem in 1995,
there was only one beaver colony in the park, said Doug Smith, a wildlife biologist in charge of the Yellowstone Wolf Project.
Today, the park is home to nine beaver colonies, with the promise of more to come, as the reintroduction of wolves continues to astonish biologists with a ripple of direct and indirect consequences throughout the ecosystem.
