The Zumwalt Prairie Preserve is the largest purchase made by the Nature Conservancy in Oregon. This rolling prairie is a fragile ecosystem home to fifteen species of raptors, like the Red Tail Hawk and Short Eared Owl. Ecologists like Dennis Sheehy study the effects of a hundred years of homesteading and cattle grazing to determine how best to manage these delicate grasslands.
