Snow and cold define the landscape while returning light begins to alter daily rhythms.
About the refuge
The Sacred Place Where Life Begins
An orientation to the Arctic National Wildlife Refuge: a vast, connected landscape of mountains, tundra, rivers, coastal wetlands, wildlife, and enduring cultural relationships.
A place of connected systems
One refuge, many living landscapes.
The Arctic National Wildlife Refuge is internationally recognized for its ecological richness and remarkable beauty. Its habitats extend from the Brooks Range across foothills and tundra to the coastal plain and the waters beyond.
This guide approaches the refuge as a living network rather than a distant backdrop. Landforms, seasonal movement, wildlife habitat, and human history are closely connected across its breadth.
The refuge at a glance
Vast country shaped by movement.
The refuge covers a wide arc of northern Alaska, bringing together alpine terrain, river corridors, lowland tundra, wetlands, and the coastal plain. Each region contributes to the ecological character of the whole.
Wildlife use these connected habitats in different ways throughout the year. Caribou, birds, marine mammals, predators, and smaller species respond to snow, water, food, light, and temperature as conditions change.
MountainThe Brooks Range forms high watersheds, valleys, and routes through the northern interior.
Coastal plainA low, open landscape supports nesting, calving, feeding, and seasonal renewal.
WildlifeMany species depend on the refuge’s habitats and on connections beyond its boundaries.
Seasonal field notes
The landscape changes with the light.
Seasonal conditions influence migration, reproduction, access, plant growth, and the daily patterns of life across the refuge.
Spring
Snowmelt opens waterways, migratory birds arrive, and plants begin a short growing season.
Summer
Long daylight supports nesting, feeding, calving, and movement across tundra and wetlands.
Autumn
Temperatures fall, colors deepen, and many species begin journeys toward winter range.
Why connections matter
Protection is larger than a single view.
The refuge’s value lies in the relationships among its habitats. Rivers carry water from the mountains toward the coast. Tundra provides food and nesting ground. Coastal areas support animals during critical seasonal periods.
Industrial activity, transportation, and other disturbances can affect those relationships beyond the footprint of one structure. Understanding the refuge therefore requires attention to scale, timing, and the routes animals use across the landscape.

Questions, answered
What is the Arctic National Wildlife Refuge?
It is a large protected landscape in northern Alaska containing mountains, tundra, rivers, wetlands, coastal areas, and important wildlife habitat.
Why is the coastal plain important?
The coastal plain is a productive seasonal landscape used by wildlife for nesting, feeding, calving, and raising young.
How does wildlife use the refuge?
Different species use different parts of the refuge throughout the year, often moving between habitats within and beyond its boundaries.
Why are caribou part of this guide?
Caribou connect seasonal habitat, migration, food systems, and long-standing cultural relationships across the broader region.
