INTERNATIONAL DARK SKY RESERVES

The IDSReserve program is the epitome of IDA's mission.  Working to preserve a central core that is valuable because of its natural night, communities band together to create public awareness campaigns and conduct retrofits to restore the night sky.  

Definition: a public or private land possessing an exceptional or distinguished quality of starry nights and nocturnal environment that is specifically protected for its scientific, natural, educational, cultural, heritage and/or public enjoyment mission of a large peripheral area. The International Dark Sky Reserve consists of a core area meeting the minimum criteria for sky quality and natural darkness, and a peripheral area that supports dark sky values in the core and receives benefits from them as well. The International Dark Sky Reserve is formed through a partnership of multiple land owners and/or administrators that have recognized the value of the starry night through regulation and/or formal agreement and/or long term planning.
