Oregon Field Guide - Season 21 Episode 4
Knowles Creek used to be a floundering ecosystem, but Charley Dewberry and his team have successfully brought the stream back to life. In their attempts to restore the watershed basin surrounding Knowles Creek, Charley's team's efforts have caused the number of juvenile coho to triple since their restoration began in 1992. Once a controversial project, the scientists who defied conventional wisdom demonstrate how well the project has worked. Turkey Vultures are among the smartest birds in the worlds. Join Oregon’s foremost raptor expert, Jim Anderson, as he takes us on a comical journey from caves to canyons to a roadkill graveyard, all in search of a bird most people dismiss as “just plain ugly”. No, they’re not pretty, and yes, they eat food only after its long dead and stinky, but think about it… what would our world be like it all that dead stuff were left lying around? Update on Oregon State University project to use ocean waves off the Oregon coast to generate power.
