The Wildlife and Terrestrial Resources Division of the Department is charged with maintaining and enhancing the existing and potential habitats on and around the reservation. These habitats will support harvestable populations of wildlife and botanical resources for tribal subsistence.

Additional watershed management principles benefit the region's wildlife populations and associated habitats. The goal of these principles is to actively seek funding and cooperative management efforts that will protect, enhance, and/or restore wildlife, wetland, riparian, and botanical resources throughout Kalispel ceded lands.

The Division manages nearly 5,300 acres of reservation lands and 2,450 acres of federal wildlife mitigation lands. It is currently involved in several processes that will protect, mitigate, restore and enhance wildlife habitats within Kalispel ceded lands, which encompass more than two million acres in Washington, Idaho and Montana.
