Dark-Sky Preserves, Urban Star Parks and Nocturnal Preserves

The RASC has developed formal guidelines and requirements for three types of light-restricted protected areas: Dark-Sky Preserves, Urban Star Parks and Nocturnal Preserves. We are officially recognizing parks in Canada that apply for an official designation and meet these guidelines. Many parks across Canada have been designated in recent years - see the list below. If you have a favourite dark site, perhaps it could be designated by the RASC as a Dark-Sky Preserve, an Urban Star Park or Nocturnal Preserve, so please let us know by sending us an email to Light-Pollution Abatement Committee Chair.

Dark-Sky Preserve (DSP)

english dsp logofrench dsp logo A Dark-Sky Preserve is an area in which no artificial lighting is visible and active measures are in place to educate and promote the reduction of light pollution to the public and nearby municipalities. Sky glow from beyond the borders of the Preserve will be of comparable intensity, or less, to that of natural sky glow.

Urban Star Park (USP)

usp english logofrench usp logo An Urban Star Park is an area in which artificial lighting is strictly controlled and active measures are in place to educate and promote the reduction of light pollution to the public and nearby municipalities. Sky glow from beyond the borders of the Reserve may be visible to observers within the area, but the skies are still usable for astronomy.

Nocturnal Preserve (NP)

NP CP Bilingual BilingueA Nocturnal Preserve is an area in which artificial lighting is strictly controlled and active measures are in place to educate and promote the reduction of light pollution to the public and nearby municipalities. The primary focus is to protect the nighttime environment, and astronomical access is not a prerequisite.

 

Other non-RASC Designation Types

In addition to the stringent guidelines set by the RASC, there are organizations outside of Canada that also are promoting preservation of dark skies. These designations are included here as a convenience, but do not imply endorsement or acceptance by the RASC.
