The "International Dark Sky Places" (IDSP) is an award-winning program founded in 2001 to encourage communities, parks and protected areas around the world to preserve and protect dark sites through responsible lighting policies and public education.  

Are you a municipality or park and want to learn more about having your park internationally recognized by the International Dark-Sky Association? Or just want to take the first step by offering nighttime programs on light pollution to your park visitors?

Every year, billions of birds migrate north in the spring and south in the fall. The majority of the birds fly at night, navigating using the Moon, stars and night sky. As they pass over big cities, they can become disoriented by bright artificial lights and sky glow. An estimated 600 million birds in the U.S. die each year from collisions with buildings. A recent study published by Cornell Lab of Ornithology ranked metropolitan areas in Missouri, Kansas and Illinois where, due to a combination of light pollution and geography, birds are at the greatest risk of becoming attracted to and disoriented by lights and crash into buildings.   

IDA Missouri spearheads a multi-state collaboration of organizations called Lights Out Heartland to keep birds safe as they migrate a night.  Visit our dedicated website to learn more about this collaboration.
