Although there are variable reports, some sources report that there are four species of mammals found exclusively in Oregon: the Baird's shrew, the Pacific shrew, the camas pocket gopher, and the red tree vole North Oregon Coast “distinct population segment”23 However, other sites list the red tree vole as present in northern California According to the Oregon State University libraries Oregon Wildlife Explorer website, one hundred thirty-six mammals have been described, exclusive of the marine mammals Most of these are smaller creatures weighing under one kilogram, active primarily at night, with a tendency towards more inconspicuous ways of life Some of the larger, more iconic, carnivorous species have been driven from the region Others are present, but in lesser numbers compared to the smaller species2

The American Society of Mammalogists provides a more exhaustive listing of species4 Grizzly bears are no longer listed According to the list, 12 specimens of Canada lynx remain The gray wolf populations has been increasing in recent years and is monitored by the Oregon Department of Fish and Wildlife5 The first confirmed wolf sighting in western Oregon since 1947, known as Journey OR-7, was born in April, 2009 is 6
