Oregon Field Guide - Season 27 Episode 10
Pikas are the adorable masters of the high country. So why are thousands of them living just a few hundred feet above sea level in the Columbia River Gorge? Oregonians help monarch butterflies with the one plant they need to survive: milkweed. We will also meet a group of ecologists who have cooked up a clever way to address the problem of invasive species – one bite at a time.
