Temperate Rainforest
The park's temperate rainforest biome is characterized by lush vegetation, including Sitka spruce, western hemlock, and a rich understory of ferns and mosses. This biome supports a variety of wildlife, including black bears, bald eagles, and various species of salmon.
Alpine Tundra
The alpine tundra biome, found at higher elevations within the park, is characterized by low-growing vegetation such as dwarf shrubs, grasses, and wildflowers. This biome is home to specialized fauna, including mountain goats and marmots, adapted to the harsh, cold environment.
Glacier and Icefield
The glacier and icefield biome encompasses the vast expanses of ice that dominate the park. While life is sparse in this biome, it plays a crucial role in shaping the surrounding ecosystems through its influence on freshwater availability and landscape formation.
Marine
The marine biome of Glacier Bay includes the park's fjords, bays, and the waters of the Gulf of Alaska. This biome supports a diverse array of marine life, including humpback whales, orcas, sea otters, and a variety of fish and invertebrates.
Intertidal Zone
The intertidal zone biome is characterized by the area between the high and low tide marks, supporting a variety of specialized plants and animals. Common species include barnacles, mussels, sea stars, and various types of algae and seaweeds.
Coastal Estuary
The coastal estuary biome features brackish waters where freshwater from rivers and streams mixes with saltwater from the ocean. This biome provides critical habitat for migratory birds, fish, and other wildlife and is rich in nutrients supporting a diverse array of life.
