- The Palouse Ecoregion (storymaps.arcgis.com)
The Palouse Prairie is an endangered ecosystem spanning Eastern Washington, Western Idaho, and Northeastern Washington (Noss et al. 1995). Different sources have a variety of historical ranges throughout this region. The most widely accepted historical range was created by Black et al. 1998. Black’s map displays the extensive loss of the Palouse Prairie’s range due to agricultural land conversion. Many of these maps are fairly old paper maps. Interactive, online maps of this region are lacking and needed.

The region of southeastern Washington and adjacent Idaho that has rolling hills on deep soils is known as the Palouse. On its eastern border, this region is bounded by the forests of northern Idaho, and the Snake River forms its southern boundary. To the north and west, the Palouse is bounded by areas of flat terrain and shallow soils, places where the deep soils were scoured away by ice or water during past glaciations or floods. Some scientists use a more inclusive definition of the Palouse; they consider areas to the west and south and even parts of northwestern Montana to be part of the Palouse.

The Palouse (/pəˈluːs/ pə-LOOSS) is a distinct geographic region of the northwestern United States, encompassing parts of north central Idaho, southeastern Washington, and, by some definitions, parts of northeast Oregon. It is a major agricultural area, primarily producing wheat and legumes. Situated about 160 miles (260 km) north of the Oregon Trail, the region experienced rapid growth in the late 19th century.
