The Palouse, the traditional homeland of the Palus Band of Indians and ceded lands of the Nez Perce Tribe, crosses the Washington-Idaho border and is best known for expansive undulant hills of wheat and lentils -- a photographer's dreamscape. But this land has always been comprised of myriad ecosystems resilient with diverse flora and fauna. There are remnants of rare native Palouse prairie, vintage apple groves, lush cedar forests, man-made ponds, and several river corridors; the Palouse river walk, for example, runs through downtown Pullman and to east, passing Koppel Farm Community Garden before heading out into the farmlands and  beyond.
