So often we hear horror stories of environmental degradation. Once in awhile we need to hear the good news, the reversal of misfortune, and I’m here to tell you one such story.

Join me along the banks of Granite Creek as I tell my friend Joe about my impressions of the value of beavers in restoring an ecosystem. http://www.youtube.com/watch?v=kTlSKffiSPw&feature=youtu.be.
