Different terms have been used to describe these areas as national organizations and governments have worked independently to create programs. DarkSky International (DarkSky) uses "International Dark Sky Reserve" (IDSR) and "International Dark Sky Park" (IDSP), among other terms, when certifying Dark Sky Places. Quotes Dark skies cannot be overlooked in the environmental movement—or in any effort to create a better world for future generations. There is a unique unity that comes from living under one dark sky. Ruskin Hartley, Executive Director and CEO of DarkSky International, as quoted in "DarkSky International celebrates the certification of the 250th International Dark Sky Place" (November 3, 2025) External links Dark Sky Parks Category:Nature
