Light pollution’s effect on wildlife

Life on Earth developed with daily day and night cycles, but in our current age, with human made artificial light, species are facing altered environments. Many species need darkness for purposes of reproduction, hunting, sleep and protection. 

Species that live in or migrate through Great Basin Naitonal Park are fortunate. The preservation of natural resources, including dark skies, benefits tens of thousands of species each year.

Great Basin National Park and Great Basin National Park Foundation are part of the Basin and Range Dark Sky Cooperative, which works with communities throughout the Basin and Range landscape to encourage night sky preservation through intelligent outdoor lighting. By working together, thousands of wildlife species gain protection, such as migratory birds who use starscapes for navigation and migration.
