Oregon's incredible wildlands are inhabited by an abundant diversity of fish and wildlife. But some of the heftiest members of the state's native megafauna club no longer range its forests, hills, and valleys. Naturalist Ethan Shaw explored the history of two of the West's most iconic species - the mighty American bison and grizzly bear - and their relationship to Oregon. Ethan dived into some of what we know about the where and the when of these big beasts in the Beaver State and how they may have once integrated into local ecosystems. He touched a little on what possible future the bison and grizzly could have here.
