|Habitat types are diverse and varied with a
mosaic of forests, glacial fed streams and rivers, spring creeks, riparian areas, glacial
potholes, and small remnants of native Palouse prairie.
This natural diversity, along with irrigated
pastures and small crop fields, makes the Mission Valley an oasis for a unique array of
fish and wildlife. Not only does the valley support some of the highest densities of
ground nesting migratory birds in the lower 48 states, it is also home to a number of
threatened and endangered species. These include bull trout, peregrine falcon, gray
wolf, and bald eagles.
