Invisible ties; roots, rot, and the riot of life in an old-growth forest. Photographer David Paul Bayles focuses on landscapes where the needs of forests and human pursuits often collide, sometimes coexist, and on occasion find harmony. His connection with trees was forged in the mid-seventies when he worked for four years as a logger in the Sierra Nevada mountains. Last year, he was awarded an ongoing residency at the 16,000-acre H. J. Andrews Experimental Forest near Blue River, Oregon.
