List of mammals of Oregon facts for kids

The North American beaver is the state mammal of Oregon.

This is a list of all the wild mammals that live in the U.S. state of Oregon, or those that used to live there but are now gone. This list includes animals found on land and along Oregon's coast. We've gathered this information from trusted sources like the American Society of Mammalogists. Sometimes, these lists might have small differences, which we'll point out. The animals are grouped by their main types, called "orders," and then listed in tables by their "families." We also mention how rare or common each species is, based on the IUCN Red List. The pictures you see are of animals from Oregon or nearby states. We don't list animals that are only found in zoos or as pets.

Oregon is home to many different kinds of mammals! There are about 139 different wild mammal species living here or that once lived here. These amazing creatures are grouped into different "orders" based on their shared features. For example, there are many carnivores (meat-eaters), bats, and rodents (like mice and squirrels). Each group plays an important role in Oregon's natural world.

Protecting Mammals

Animals around the world are given a special status by the IUCN Red List. This helps us understand if they are safe or if they need our help to survive. Animals are put into different groups based on how many there are, if their numbers are shrinking, and where they live.

• Least Concern: These animals are doing well and are not currently in danger.
• Near Threatened: These animals might become threatened in the future, so we need to keep an eye on them.
• Vulnerable: These animals are facing a high risk of becoming endangered.
• Endangered: These animals are in very high danger of disappearing forever.
• Critically Endangered: These animals are extremely close to becoming extinct.
• Extinct in the Wild: These animals only live in zoos or special protected areas, not in nature.
• Extinct: These animals have completely disappeared from Earth.
• Data Deficient: We don't have enough information to know if these animals are safe or in danger.
• Not Evaluated: These animals haven't been checked yet.

Land Mammals

Carnivores

Between 25,000 and 30,000 black bears live in Oregon.

Carnivores are a very diverse group of mammals. Their name comes from a Latin word meaning "flesh devourer," because many of them eat meat. Oregon is home to many different carnivores. The gray wolf has recently returned to Oregon, especially in the northeast. The grizzly bear used to live in Oregon but disappeared around 1940. Even though they are gone, they are still included in this list because they were once part of Oregon's wildlife.
