International Dark Sky Communities

The International Dark Sky Community (IDSC) designation is the first in the series of the International Dark Sky Places (IDSP).  The IDSC was conceived in 2001 to recognize communities that had taken extraordinary steps in preserving the natural night.  The IDSP task force was then formed in 2006 to explore expanding the program to include Parks and Reserves.

The task force is international in scope, with diverse qualifications all pertaining to the protection of the night.  Task force members include astronomers, ecologists, park employees, planners, and general conservationists.

The IDSC designees must adhere to stringent standards that protect the natural night sky through outdoor lighting plans and ensure the continuation of this protection through planning and zoning directives.  The following is the official definition of an International Dark Sky Community:

a town, city, municipality, or other legally organized community that has shown exceptional dedication to the preservation of the night sky through the implementation and enforcement of quality lighting codes, dark sky education, and citizen support of dark skies.

A community is awarded the IDSC designation after task force and IDA board approval of a comprehensive application.  To read the requirements for submission and the program details click here.  You may also contact us.
