In 2011 the Royal Astronomical Society of Canada (RASC) designated Jasper National Park as a Dark Sky Preserve (DSP). The application for DSP status was prepared by Parks Canada in partnership with the Municipality of Jasper, Tourism Jasper and Jasper Park Chamber of Commerce.
Dark Sky Preserves support responsible and efficient lighting and encourage public awareness and education programs.
The town of Jasper lies within the JNP Dark Sky Preserve and must adhere to the DSP lighting protocols. All lighting in the town must eventually be dark sky friendly. Non-compliant lighting in town contributes to sky glow over the park through glare and light trespass that waste electricity and reduce visibility for motorists, pedestrians and cyclists.
Dark sky friendly lighting does not mean no light! With dark sky friendly lighting, light is directed where it is needed. Outdoor lighting when appropriately directed can improve visibility and safety while minimizing energy use, operating costs and glare. Improperly aimed lights can shine onto nearby properties creating conflict with neighbours, drivers, and pedestrians.
Find Dark Sky Friendly Light Fixtures International Dark-Sky Association (IDA) offers a Fixtures Seal of Approval Program that certifies outdoor lighting fixtures as being Dark Sky Friendly, meaning that they minimize glare while reducing light trespass and sky glow. All products approved in the program are required to be fully shielded and to minimize the amount of blue light in the nighttime environment. Information about Dark Sky Retailers is available on the IDA website.
