Arctic Tundra
The Arctic tundra biome at Kobuk Valley National Park is characterized by its cold climate, permafrost, and short growing seasons. The vegetation primarily consists of low shrubs, grasses, mosses, and lichens. This biome provides habitat for various species such as caribou, Arctic foxes, and migratory birds.
Boreal Forest (Taiga)
Although predominantly tundra, parts of the park, especially along the Kobuk River, feature boreal forest, also known as taiga. This biome includes a mix of spruce, birch, and poplar trees, which support diverse fauna such as moose, black bears, and numerous bird species.
Riparian Zones
The riparian zones along the Kobuk River and other waterways in the park boast lush vegetation compared to the surrounding tundra and boreal forest. These areas support willows, alders, and a variety of grasses and sedges. Riparian zones provide critical habitat for beavers, fish, and a variety of bird species.
Sand Dunes
The Great Kobuk Sand Dunes represent a unique biome within the park, consisting of expansive, wind-formed sand dunes that can reach up to 100 feet (30 meters) in height. Despite the harsh conditions, some hardy plants like the Arctic lupine and wild rye grass manage to survive, and the area is an important part of the caribou migration routes.
