Wildlife in the Okanogan-Wenatchee National Forest 

Due to its enormous size, the Okanogan-Wenatchee National Forest is home to many different animals, fish, and birds. The wide and diverse range of habitats in this Washington State forest means that the animals living here live comfortably and feel right at home. Here, you’ll find plenty of opportunities to discover and observe animals in their natural habitat! Here is just a small sample of the animals you can expect to see in the Okanogan-Wenatchee National Forest:


The lynx is a medium-sized wild cat species. There are four types of lynxes around the world, and in the Okanogan-Wenatchee National Forest, you may come across the Canada lynx or the bobcat. The Canada lynx is larger and can weigh from 18 to 31 pounds, while the bobcat is the smallest lynx species, weighing 16 to 30 pounds. The Canada lynx is more likely to be found in forests and tundra, and the bobcat tends to inhabit woodlands, swamps, and mountains.

Lynxes have short tails and tufts of black fur on the tips of their ears. They have a ruff under their neck that looks like a bowtie. Fur color varies from medium brown to almost white with dark brown spots. All lynxes have white fur on their chests, abdomens, and the inner parts of their limbs. Lynxes are predators and create dens under ledges or in crevices. They eat a wide range of animals, including white-tailed deer, reindeer, snowshoe hares, fish, foxes, squirrels, sheep, turkeys, and goats.


The Okanogan-Wenatchee National Forest is home to a healthy population of elk, the largest members of the deer family. Elk are found throughout North America and are a fairly common sight for visitors to the forest. These elegant creatures can be found in various habitats, including in mountain meadows, forests, and grasslands.

They have a reddish-brown coat and distinctive long hair to help them keep warm in the winter. During mating season, the males can be observed bugling — this is a loud vocalization they use to attract females and is an awesome thing to experience. Elk are an essential part of the Okanogan-Wenatchee National Forest’s ecosystem and are a beloved sight for visitors to the forest.

Mountain Goat

Mountain goats occupy only northwestern North America and can be found from the Canadian border to the Oregon border. In Washington State, there are between 2,400 and 3,200 mountain goats. These goats are quite easy to distinguish from other goats, as they have fully white fur coats, shiny black horns, beards, and short tails. Mountain goats prefer higher elevations, near steep cliffs and slopes above the tree line.

These creatures were built for climbing and are able to climb steep, rocky slopes due to their useful hooves. Mountain goats are herbivores and like to spend a lot of time grazing. Their diet includes grasses, herbs, ferns, lichens, twigs, and leaves. Make sure you check out the cliffs and mountains to catch a glimpse of these fearless animals!

Black Bear

The black bear is endemic to North America and is found throughout the Okanogan-Wenatchee National Forest. It is a medium-sized bear, and although the name suggests otherwise, black bears can have many different colored coats. In fact, you can even find black bears with white, blonde, and light brown coats! Generally, adult males are larger than adult females and weigh around 260 pounds, while adult females weigh around 150 pounds.

Black bears are omnivores, and their diet depends largely on the seasons and the location. Generally, they will feed on berries, fruit, insects, fish, and even human food. Black bears like living in forested areas, so watch out for these great animals on your hike! And make sure to take some bear spray with you, just in case.


This small furry animal lives in the rocky alpine areas of the Okanogan-Wenatchee National Forest. They are closely related to rabbits and hares but are a lot smaller, weighing only 4 to 6 ounces and growing to around 6 to 8 inches long. Their dense fur ranges in color from gray to brown and provides warmth in cold alpine environments.

Pikas are herbivores and feed on a variety of alpine plants, such as grasses, sedges, and wildflowers. During the summer, they gather and store large amounts of plant material in their dens, which they use to survive during the winter when food is more scarce. Being such a tiny animal, you might have a hard time finding these little critters. However, they are a pleasant and well-worth sight for the determined photographer!

Adult males are generally smaller than adult females; males usually weigh between 12 and 35 ounces, and adult females weigh between 25 and 53 ounces.

The peregrine falcon lives along mountain ranges, river valleys, coastlines, and even in cities. This makes the Okanogan-Wenatchee National Forest a great home for these birds! The diet of the peregrine falcon is generally medium-sized birds. They will feed on pigeons, waterfowl, songbirds, parrots, seabirds, and more.


The marmot is a large ground squirrel that is native to the alpine and subalpine regions of the Okanogan-Wenatchee National Forest. A few different species of marmots can be found within the forest, including the yellow-bellied marmot, the hoary marmot, and the Olympic marmot. Typically, it has a short, stout body, short legs, and a short bushy tail. One of the most distinctive features of the marmot is its vocalizations. They have a deafening and piercing whistle that they use to communicate with other members of their colony. The whistle can be heard echoing throughout the valleys and mountains of the Okanogan-Wenatchee National Forest and is a very common sound to hear for visitors to the forest.

Marmots feed on grasses, sedges, wildflowers, and other alpine plants. They are primarily active during the warmer months and can be seen basking in the sun atop rocks or digging burrows in the ground. Marmots offer an important balance to the ecology of the forest, as they maintain the plant populations and provide food for predators like weasels, foxes, and birds of prey.
