Oregon Field Guide - Season 24 Episode 3 Cattle Drives, Gorge Weeds, Timberline 75th
10.00 48 minutes Cattle Drives A historic cattle ranch in southeastern Oregon moves cows every day. In many ways, cattle drives there have changed little since a century ago. The ranch herds cattle from one end of a million acre range to the other over the course of a year. Gorge Weeds The Columbia Gorge is one of our favorite playgrounds. But recreational use brings in noxious weeds that crowd out native species and upset the area’s ecological balance. We take a look at the challenges state agencies, land managers and non-profit groups face in trying to control the influx of these invasive “game-changers” and their efforts to coordinate these efforts. Timberline 75th Oregon’s Timberline Lodge was part of FDR’s Works Progress Administration - a program that not only put people to work, but also preserved some of the finest of the Northwest’s indigenous arts. Despite the museum-quality art and hand-made furnishings, Timberline is still open to the public today.
