This attractive thematic set features six conservation labels issued by The Wilderness Society, Washington, D.C., highlighting the diverse natural heritage of Alaska. The designs present iconic landscapes and wildlife including the Little Kobuk Sand Dunes (Kobuk Valley National Monument), Lesser Snow Geese and Polar Bear with Cub (Arctic National Wildlife Refuge), Muskeg Pond (Tongass National Forest), Fog-covered Romanzo(f) Mountains, and vibrant wildflowers from Wrangell–St. Elias National Park. Produced as conservation promotional seals rather than postal issues, the series is popular among thematic collectors specializing in nature, wildlife, and environmental preservation. The consistent photographic layout and regional park identification make the set visually cohesive and desirable for Alaska-themed exhibits.
