The Southwest Information Node (SWIN) includes Arizona, Colorado, Nevada, New Mexico, and Utah. The southwest is home to an incredibly diverse natural and political environment and the rapidly growing population interacts with complex natural features such as deserts, plateaus, rivers, and mountain ranges.
The Great Basin Information Project provides consolidated and efficient access to information about the Great Basin and the Columbia Plateau Regions of eastern Washington and Oregon, southern Idaho, northern Nevada and Utah, and portions of northeastern California. Three major plant communities grow in the Great Basin and Columbia Plateau: sagebrush, salt desert shrub, and pinyon-juniper woodlands. The Great Basin and Columbia Plateau regions comprise a large area of the western United States, approximately 225,674 sq. miles in size.
