Upper Columbia Basin Network Parks
There are nine National Park Service units in our network, located in Idaho, Montana, Oregon, and Washington. These parks occupy portions of the Columbia Plateau and Snake River Plain geographic regions, where expanses of sagebrush-steppe are the predominant ecosystem type.
Many plants and animals that occur in here are unique to the semi-arid habitats of the upper Columbia Basin, including the greater sage grouse, spotted bat, Columbia spotted frog, and hedgehog cactus. In addition, these parks contain the only pinyon pine woodland in Idaho, and are one of the last strongholds of the Arctic grayling south of Canada.
