Alaska's public lands encompass large natural areas that display a wealth of geological and biological diversity. Considered by scientists as "living laboratories," these lands provide opportunities to study natural processes and the effects of human activities.   

Understanding the natural processes at work on public lands provides a continual challenge to state and federal agencies. These agencies are doing the best they can to study and preserve the environment for people to enjoy. Environments set aside as public lands provide largely intact ecosystems filled with threatened or endangered species making for a unique viewing and/or scientific experience.

Alaska's public lands contain intact biological communities that serve as benchmarks against which to measure change. As such they have global significance.

As home to many natural and scientific wonders, Alaska's public lands offer special opportunities for observing and learning about nature and science.
