Columbia Plateau
This large region occupies most of the south central state and has the driest climate of any region. Repeated flooding from Lake Missoula in the last ice age created Channeled Scabland over much of this area. Historically shrub-steppe and grasslands predominated but with the damming of the Columbia and the resulting irrigation much of this habitat has been converted to agricultrue. Potholes and marshes throughout host abundant waterfowl. More from Birdweb.
