Nature Sounds Recording John Hartog is a nature sound recordist. Just as painters paint a landscape, or photographers photograph it, John heads into the countryside (Sauvie Island and Hart Mountain Antelope Refuge) with a microphone and a recording deck to capture the natural sounds of wild Oregon. These audio ‘snapshots’ in time tell us something about the place we live, and the wildlife that share it with us. Silver Falls State Park 1.5 million people every year make Silver Falls State Park the most popular state park in Oregon. They may be surprised to learn that 80 years ago that a town sat there, the area was full of stumps and the biggest waterfall was a daredevil's playground. Silver Falls was saved by a single-minded photographer determined to protect it for everyone to enjoy. Zumwalt Cooperation Despite a century of cattle grazing, Oregon's Zumwalt Prairie remains healthy. A new study by Oregon State University shows low to moderate levels of grazing does not harm the survival of ground nesting birds. The Nature Conservancy's Zumwalt Prairie Preserve also allows grazing in a rare partnership of ranchers and conservationists.
