Viewing Wildlife Ethically - Take The Pledge!

The state of Alaska offers the following ethics guidelines. Pledge to uphold them and keep the wilderness 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.
  • Stay on designated trails whenever possible.
  • 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, 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.
