[7] Sanders County is a "destination hunting locale" with trophy specimens of White-tailed Deer (Odocoileus virginianus), Mule Deer (Odocoileus hemionus), Rocky Mountain Elk (Cervus canadensis nelsoni), Shiras Moose (Alces alces Shirasi), Mountain Goat(Oreamnos americanus), and Bighorn Sheep (Ovis canadensis Canadensis) rounding out huntable ungulate species and Black Bear, Cougar and Wolves comprising the huntable carnivores.

Grizzly bear, the Montana state animal, are also found in the county, but as an endangered species, hunting them is prohibited.

Western Meadowlark, the state bird are found sparsely in the meadow areas of Sanders County along with Redwing Blackbird and Mountain Bluebirds.

Catch and release fishing is required to maintain fishable populations of the two natives, which now compete with introduced rainbow trout, and warm-water species, such as largemouth bass, yellow perch, Northern Pike, and walleyes that have been introduced and thrive in the modified habitat of the Clark Fork River's reservoirs.

It lies entirely on the western slopes of the Rocky Mountains with a mixed coniferous forest dominating the plant community.

Douglas fir/Ponderosa pine (Montana state tree) climax plant community dominate much of the county, but there are numerous other conifers found there as well in pockets of micro-climates suited to their needs.

Numerous broadleaf species proliferate in Sanders County: Rocky Mountain Maple, Red Alder, Paperbark Birch, Chokecherry, cottonwood, and poplar.

Arguably the most popular broad-leaf shrub in Sanders County is the Rocky Mountain huckleberry (Vaccinium membranaceum).

Though related to the common blueberry (Vaccinium corymbosum) very few have managed to grow Rocky Mountain huckleberry in domestic cultivation.
