Brown Bat Range Map

Bats

Bats (Chiroptera) can be found on every continent except Antarctica. There are more than 40 species of bats in the United States, 15 of which can be found in the Pacific Northwest. The most common of these is the Little Brown Bat (Myotis lucifungus).

Beavers

Once one of the most widely distributed mammals in North America, Beavers (Castor canadensis) have suffered a sharp decline in their numbers. Unregulated trapping for Beaver pelts has decimated populations. Landowners have also killed Beavers who build dams that flood agricultural or other private lands.

Black Bears

Black Bears (Ursus americanus) are the most common and widely distributed bear in North America. Historically they ranged over most of the forested regions of North America but they currently reside in 38 states, approximately 62% of their historic range. In Washington the population is estimated to be between 25,000 and 30,000 individuals.

Bobcats

Historically, Bobcats (Lynx rufus, named for their short tail) could be found across the 48 contiguous United States, Canada and Mexico. However, due to agriculture expansion and hunting for their fur, populations declined and became restricted in the Midwest U.S. and Central Mexico. 
Coyote Range Map

Coyotes

Known in Native American lore as the "trickster," the coyote (Canis Latrans) has survived and thrived by being highly adaptable. Coyotes were once restricted to sagebrush lands, brushy mountains and open prairies of the American West but by taking advantage of the extirpation[[sitetree_link,id=]] of wolves and other human activities they were able to expand their range throughout North and Central America.
Deer Range Map

Deer

Deer are a common sight throughout Washington State, although the species and subspecies of deer varies by region. There are two species and four subspecies of deer that occur in Washington; on the west side of the Cascade Mountains the Columbian Black-tailed Deer (Odocoileus hemionus columbianus) is the dominant sub-species. You can find Rocky Mountain Mule Deer (Odocoileus hemionus hemionus) and White-tailed Deer (Odocoileus virginianus idahoensis) east of the Cascade crest, and the endangered Columbian White-tailed Deer (Odocoileus virginianus leucurus) are found in pockets of habitat along the lower Columbia River.

Mice and Rats

Mice and rats are well-known rodents people usually associate with cities. Known as commensal, some species of mice and rats have a long history of living close to people. Fossil records place evidence of House Mice in a Neolithic Turkish community more than 8,000 years ago. But there are also wild species of mice and rats scampering around the forests and plains of North America that steer clear of humans.

Moles

Moles are very diverse and widespread within the United States. They spend almost all of their time underground and some are even semi-aquatic. Although their presence is well known by their recognizable mounds, they are rarely seen and little is still known about these beneficial critters.

Mountain Beavers

The Mountain Beaver (Aplodontia rufa) is a primitive rodent that spends the majority of its time underground. Its name is a misnomer as it is not actually a beaver and it prefers lower elevations.

Opossums

The Virginia Opossum (Didelphis virginianus) is the only marsupial native to North America; however, they are not native to the western United States. Known simply as "possums," they originally lived only in the southeastern United States and Central America. Virginia Opossums were introduced to the West in 1890 and currently have established populations along the West Coast from British Columbia to San Diego.

Rabbits, Pikas and Hares

More than 15 species of rabbits, pikas and hares, collectively referred to as lagomorphs, are widely distributed across North America. Washington State is home to eight of these species—six native species: Nuttall’s Cottontail, Pygmy Rabbit, Pika, Snowshoe Hare, Black-tailed Jackrabbit and White-tailed Jackrabbit and two non-native or introduced species: Eastern Cottontail and Domestic Rabbit.

Raccoons

Raccoons (Procyon lotor) are widely spread across North America, extending from Mexico into parts of Canada and almost continuously between both coasts. Raccoons dramatically increased in density beginning in the 1940s with a concomitant increase in distribution. Today they occur in the mountains and deserts where they were previously rare or absent.

River Otters

North American River Otters (Lontra canadensis) were once found across most of North America and in all major waterways of the United States and Canada occupying one of the largest geographic areas of any North American mammal.

Skunks

The skunk family (Mephitidae) consists of 13 species, almost all of which are restricted to the New World from Southern Canada to the Strait of Magellan in South America. The exception are Stink Badgers who can be found in Indonesia. Skunks are known for their ability to spray a strong smelling liquid to ward off predators.

Squirrels and Chipmunks

Tree squirrels and chipmunks are some of the most familiar members of the rodent order. They are frequently seen in urban areas and city parks. Tree squirrels separate themselves from other members of the squirrel family because they living mostly among trees and not in burrows like ground squirrels. Chipmunks, however, spend the majority of their time on the ground but are capable of climbing trees.

Wolves

After an absence of more than 70 years, Gray Wolves are returning to Washington State. This is an exciting time for conservationists and wildlife enthusiasts who value the role this keystone species plays in maintaining a healthy ecosystem. According to the Washington Department of Fish and Wildlife (WDFW), wolves were formerly common throughout much of the state, but as ranching and farming by European-American settlers expanded during the period between 1850 and 1900, the wolves were heavily trapped, poisoned and hunted. By the 1930’s, wolves had been eliminated as a breeding species in Washington.
