A bear splashes into a stream and emerges with a spawning salmon ... tundra swans glide elegantly across a boggy pond ... a porcupine curls up and shows his quills to a curious hiker ... a sharp-shinned hawk dives on a redback vole ... wolves howl into the winter night. Lake Clark National Park and Preserve teems with wildlife. Among the reasons congress set aside Lake Clark as a national park and preserve was to protect habitat for wilderness dependent populations of fish and wildlife. The area's intact ecosystems support a full complement of sub-arctic wildlife species, none of which are endangered or invasive species.

The red fox is found throughout Lake Clark National Park & Preserve, and much of Alaska.

Salmon, rainbow trout, and arctic grayling are among the twenty-five species of freshwater and anadromous fish spend part or all of their lives in the park and preserve’s waterways. Anadromous fish are born in fresh water, spend most of their lives in the ocean, and return to fresh water to spawn. To learn more, look through the following links:

Viewing Wildlife Ethically - Take The Pledge!

The state of Alaska offers the following wildlife viewing ethics guidelines. Pledge to uphold them and keep the wildlife wild!

  • Give wildlife plenty of space. Binoculars and spotting scopes allow you to view wildlife without getting too close.
  • Approach wildlife slowly, quietly, and indirectly. Always give animals an avenue for retreat.
  • Try to view animals without changing their behavior. Avoid using calls or devices that attract wildlife. Resist the temptation to throw rocks to see a flock fly. Remember - harassing wildlife is illegal.
  • Be respectful of nesting and denning areas, rookeries, and calving grounds. Well-meaning but intrusive visitors may cause parents to flee, leaving young vulnerable to the elements or predators.
  • Leave "orphaned" or sick animals alone. Young animals that appear alone usually have parents waiting nearby.
  • Restrain pets or leave them at home. They may startle, chase, spread disease, or even kill wildlife.
  • Let animals eat their natural foods.
  • Learn to recognize signs of alarm. These are sometimes subtle. Leave if an animal shows them.
