The federal government's map identifying the five different ecosystems holding grizzly bears in the Lower 48; all of which are "biological islands" unconnected to one another.  The one in brown at the top is the Cabinet-Yaak Ecosystem and the one in yellow, below it, is the Selway-Bitterroot Ecosystem of northern Idaho and western Montana. There is no grizzly population there today but it's been identified as grizzly-friendly wild lands and a key place which could help connect bear in the Greater Yellowstone Ecosystem, to the south, with bear populations to the north.
