Low Elevations: Taiga/Taiga Forests
The Taiga biome in Denali National Park is characterized by having a long, and cold winter, and coniferous forests consisting of mostly pines, spruces, and larches. There is heavy snowfall during winter months, and the quality of the soil is very poor. There are little nutrients in the soil. The taiga biome is a continuous belt of coniferous trees, which are basically trees that bear cones and evergreen leaves. Animals that live in the taiga biome include Grizzly Bears, eagles, and elk.
Middle Elevations: Arctic Tundra
The arctic tundra biome in Denali National Park is characterized by virtually no trees, and extremely cold temperatures. The tundra is a cold, desert-like environment with little to no precipitation. A permafrost, a layer of permanently frozen subsoil, is present all throughout the tundra biome. There are few nutrients available, so the animals that live in the arctic tundra, such as caribou, arctic hares, wolves, are usually carnivorous. Glaciers can usually be seen in lakes or other bodies of water. This biome is in the middle elevations.
High Elevations: Alpine Tundra
The alpine tundra biome in Denali National Park is seen mostly in the upper mountain regions. The nighttime temperature is usually below freezing most of the year. The soil is well-drained, unlike the tundra, meaning that water can easily be absorbed by the soil. There are many rocks and much snow in the alpine tundra. Animals in the alpine tundra zone include voles, squirrels, and sparrows.
