The Hanford Reach National Monument,  established in 2000, is a crescent of land with the last free-flowing stretch of the Columbia River flowing through it. It’s also a major incubator of salmon. The Department of Energy calls it “the largest natural animal and plant community in the arid and semi-arid shrub-steppe region of North America.” 

The Reach has remained largely pristine, protected from agriculture and development, because it was a security buffer around the central Hanford site – one of the most contaminated spots on earth. 
But the Reach is still home to a wide variety of  plants and animals, including endangered plant species like the White Bluffs bladderpod and the endangered ferruginous hawk. We get a first hand tour from Mike Livingston, the Washington Fish & Wildlife regional director for south central WA.
