America's national parks contain many cherished treasures. Among them are captivating natural sounds and awe-inspiring night skies. The joy of listening to the quiet symphony of nature and the wonderment of seeing the Milky Way stretching overhead are unique experiences that can still be found in many of our national parks.

Natural sounds and natural lightscapes are essential in keeping our national treasures whole. They are magnificent in their own right and inspirational to the visitors who come to national parks. They are vital to the protection of wilderness character, fundamental to the historical and cultural context, and critical for park wildlife.
