Central Oregon is home to a rich diversity of wildlife. From majestic mammals and vibrant birds to fascinating aquatic species, the region's fauna reflects its varied habitats and ecosystems.
Central Oregon hosts a variety of mammals adapted to its diverse environments, from the high desert to forested mountains. The region's most iconic species include mule deer, elk, pronghorn antelope, and various small mammals.
Central Oregon's high desert regions host unique mammals adapted to arid conditions. Notable species include jackrabbits, ground squirrels, badgers, and pronghorn antelope. The pronghorn is North America's fastest land mammal, capable of reaching speeds of up to 55 mph.
These mammals have evolved specialized adaptations to survive in the challenging desert environment, including water conservation mechanisms and the ability to travel long distances in search of resources.
The forested areas of Central Oregon, particularly in and around the Cascade Range, host a rich diversity of mammals. Black bears, cougars, elk, mule deer, and various squirrel species are common inhabitants of these ecosystems.
Forest mammals play crucial roles in seed dispersal, vegetation management, and as prey for larger predators. The complex forest ecosystems of Central Oregon support intricate food webs and ecological relationships.
Rivers and streams in Central Oregon create vital riparian corridors that support numerous mammal species. Beavers, river otters, mink, and various small mammals depend on these water-rich environments.
Beavers are particularly important as ecosystem engineers, whose dams create wetlands that benefit countless other species. Their activities improve water quality, reduce erosion, and create habitats for fish, amphibians, and birds.
Central Oregon is a bird watcher's paradise, with numerous species inhabiting its diverse ecosystems. From raptors soaring above the high desert to songbirds in the pine forests, the region offers ample opportunities for bird watching throughout the year.
Central Oregon's arid landscapes host specialized bird species adapted to these challenging environments. Common residents include sage thrashers, Brewer's sparrows, sage sparrows, and greater sage-grouse—whose elaborate mating displays are one of nature's great spectacles.
Many of these birds have cryptic coloration that helps them blend into the sagebrush and juniper landscapes, providing camouflage from predators and allowing them to hunt or forage more effectively.
The Cascade Range and forested areas of Central Oregon support a rich variety of bird species. Look for pileated woodpeckers, mountain chickadees, Steller's jays, and numerous owl species including the northern spotted owl and great gray owl.
Different forest types—from dense mixed conifer to open ponderosa pine—attract different bird assemblages. Some species require old-growth conditions, while others thrive in forest edges or recently burned areas.
Central Oregon's rivers, lakes, and wetlands attract numerous water-loving birds. Great blue herons, sandhill cranes, a variety of ducks, and bald eagles are commonly seen in these habitats. During migration seasons, these areas become hotspots for birdwatching.
The region's wetlands serve as crucial stopover points for many migratory birds traveling along the Pacific Flyway. Areas like the Malheur National Wildlife Refuge provide essential habitat for these long-distance travelers.

The rivers, lakes, and streams of Central Oregon support a diverse array of aquatic life. From native trout to various amphibians, these water bodies are vital ecosystems that contribute to the region's biodiversity.
Follow the remarkable journey of salmon in Central Oregon's rivers. Click through the stages to learn about their life cycle:
Female salmon lay eggs in gravel nests called redds, where they're fertilized by males.
After hatching, young fish called alevins remain in the gravel, feeding from attached yolk sacs.
When yolk sacs are depleted, young fish emerge from the gravel as fry and begin feeding independently.
Smolts undergo physiological changes preparing them for life in saltwater as they migrate downstream.
After maturing in the ocean, adults return to their birth streams to spawn, completing the cycle.
Central Oregon's diverse landscape supports a wide variety of plant communities, from high desert sagebrush to alpine wildflower meadows. The region's native plants have adapted to the area's unique climate and soil conditions.

Fire has shaped Central Oregon's landscapes for millennia. Learn how different ecosystems respond to and depend on fire:
Fire regimes describe the pattern, frequency, and intensity of wildfires that typically occur in an ecosystem over time. Central Oregon's ecosystems have evolved with specific fire regimes:
Indigenous peoples in Central Oregon actively managed landscapes with intentional burning for thousands of years, maintaining healthier forests and fostering food-producing plants like huckleberries and camas.
Plants and animals in Central Oregon have evolved various adaptations to survive and even thrive with periodic fires:
Some wildlife species, like black-backed woodpeckers, specifically seek out recently burned forests to feed on bark beetles that colonize fire-killed trees.
Fire management in Central Oregon has evolved significantly over time:
Modern fire management increasingly embraces the concept of "pyrodiversity"—the idea that a mosaic of different fire histories across the landscape supports greater biodiversity and ecosystem resilience.
See how forest density affects fire behavior. Click the buttons to observe different scenarios:
Widely spaced trees with grassy understory allow frequent, low-intensity fires that clear ground fuels without harming mature trees.
In natural conditions, fires typically remain on the forest floor, moving quickly but with low flame heights. Most mature trees survive these fires.
Central Oregon's clear air and low light pollution make it an exceptional place for stargazing. From the Milky Way to meteor showers, the night skies here offer spectacular celestial displays throughout the year.
