What happens when a key species is reintroduced to an ecosystem? The reintroduction of wolves to Yellowstone National Park in 1995 gave scientists a rare opportunity to study the consequences. Since that time, the cascade of effects has been profound & wide ranging. Not only did species return, but the health of the rivers & trees was vastly improved. Alan Toney, master naturalist, looks at Yellowstone 30 years later & the lessons that can be applied to restoring and maintaining healthy ecosystems everywhere. FREE! All are welcome.
