List of mammals of Oregon

The North American beaver is the state mammal of Oregon.

The List of mammals of Oregon lists every wild mammal species living within or recently extirpated from the U.S. state of Oregon or coastal shores. Without exceptions, this list includes all species from the lists published by the American Society of Mammalogists or found in the comprehensive text Land Mammals of Oregon published in 1998. Rare instances where these two lists are discordant are noted. Species are grouped by order and then listed in sortable tables by family. The common name for each species will be followed by its binomial name. Subspecies present in the region will be discussed within the notes of the parent species. The IUCN Redlist status for each species will be presented. Images presented are from Oregon sites or adjacent states, as possible. Species found only in captivity are not listed.[1][2]

Oregon terrestrial mammals

Carnivora

Between 25,000 and 30,000 black bears reside in Oregon.[3]

Carnivora (/kɑrˈnɪvərə/ or /ˌkɑrnɪˈvɔərə/; from Latin carō (stem carn-) "flesh", + vorāre "to devour") is the most diverse of the mammalian orders. The gray wolf has recently made a much publicized reappearance in the state of Oregon and is included in the list below. The grizzly bear was extirpated from the state in approximately 1940. Since it is included in Land Mammals of Oregon, it is included in the list below.[4]

Name Species Authority Family State distribution and notes[1] Red List
Gray wolf
Canis lupus
(L., 1758)
Canidae Oregon pop. estimates end of 2013: minimum 64 individual animals, 4 breeding pairs.[5] Protected under state Endangered Species Act throughout state and under Federal ESA west of highways.[6] First confirmed in western state since 1947 was OR-7 (pictured), also known as Journey.

However, this translocation effort failed and otters soon again disappeared from the state. Occasional sightings occur in Oregon waters, most likely wanderers from neighboring states.
