The National Park Service (NPS) protects and celebrates America’s natural and cultural heritage in over 400 places. These locations include wilderness and natural regions in all the ecosystems of the U.S. and its territories; buildings, sites, and monuments that commemorate our multicultural history; and urban green spaces that support recreation and protect the unique biodiversity of cities. Whether it’s a vast wilderness area, a Civil War battlefield, a unique geological feature, a historic home, or a scenic river, there is a unit of the National Park System in every state and territory of the U.S.

The mission of the National Park Service is to preserve these special places unimpaired for future generations, and to allow for the public to enjoy and learn from them.


The Ecological Society of America (ESA) is a nonpartisan, nonprofit organization of scientists founded in 1915. Our mission is to advance the science and practice of ecology and support ecologists throughout their careers. We envision a future where people embrace science to understand and foster a thriving planet.
