Show Summary Details

Quick Reference

A distinctive tract of prairie in the Palouse region of south-eastern Washington (USA), but similar prairie also extends into Oregon, southern Idaho, and northern Utah. A rich growth of bunch grasses, especially Agropyron spicatum (blue-bunch wheatgrass), occurs on the deep, highly fertile soils formed in aeolian parent materials. Much of the Palouse prairie is now cultivated for wheat.
