Wolves• Approximately 100 wolves in Denali Park• Between 12 and 18 wolf packs live in territories that

range from 200 to 800 square miles• While a meal is anything from a mouse to a moose, the

most common prey in Denali is caribou, Dall sheep, moose, beaver, and ground squirrels.

• Wolves have brains twice the size of a domestic dog.• Leading natural cause of death for wolves is them killing

each other over territory/pack disputes.• Largest wolf captured in Denali weighed 135 pounds• Average weight is 85 for females and 105 for males• There are no accounts of wolf attacks in the park.

Plant Life

• Denali is home to more than 1,200 species of plants• Plants form the foundation for life in the park• Over 650 species of flowering plants• Located in the sub arctic biome• All of the plants are organic to the area. None have been

imported or accidentally carried over from other biomes and parts of the world. This is due to the lack of roads and small population in the surrounding area.

Dall Sheep

• Sheep on average live till they are 12• Live in the mountains in summer through fall• In early summer, sheep will graze on the tundra and will

go farther up the mountains following the snowmelt• They use the ridges and steep slopes for feeding and

resting, and the rocks and crags to elude predators• They can grow from 150 to 300 pounds• Feed on a wide variety of plants.

Fish

• Denali is not noted for its fishing.• Most streams and lakes have a high glacial silt content

resulting in poor fish habitat.• In Denali you don’t need to have a license to fish because

fishing is so poor.• There are only 14 species of fish in the park.

Birds

• There are 169 species of birds in the park• Full time resident birds are gyrfalcons, ptarmigan, black-

capped and boreal chickadees, and redpolls• Spring brings the return of 80% of bird life.
