Dark-Sky Sites
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. The focus of our Canadian Program primarily is to protect the nocturnal environment, therefore our outdoor lighting requirements are the most stringent, but also the most effective. We officially recognize Canadian Parks and other areas that meet these guidelines and successfully apply for one of these designations. Many parks across Canada have been designated in recent years - see the list below. If you have a favourite dark site, please encourage them to start the designation process by sending an email to the RASC National Office or the Light-Pollution Abatement Committee.
Dark-Sky Preserve (DSP)
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)
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)
A 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
Some Parks may choose to use more outdoor lighting than permitted in the Canadian DS Program but there are organizations outside of Canada that also are promote preservation of dark skies. These designations are included here as a convenience.
A Canadian DS Designation automatically results in a listing by the IUCN-DSAG.
