Oregon Field Guide - Season 20 Episode 9
Oregon's first hut-to-hut biking route is a doozy of a ride through the backcountry around Mount Hood. We follow the Bright boys who enjoy the scenery even as they struggle to stay on course. A tiny beetle which has devastated entire forests in western North America has returned with a vengeance to Oregon. See how the mountain pine beetle is being dealt with. Colorado's mature lodge pole pine forests have been decimated, see how Oregon foresters hope to avoid the same fate. We’ll show you the latest technology to monitor the health of our streams.
