Preservation of the natural world
The mission statement for the National Parks Service, the folks responsible for all of our National Parks, is to “preserve unimpaired the natural and cultural resources and values…for the enjoyment, education, and inspiration of this and future generations.”
Limiting light pollution for the benefit of the many species of birds, bugs and nocturnal mammals that call Grand Canyon home is in line with this mission. Not to mention for the benefit and enjoyment of people who visit, and live nearby.
International Dark Sky
According to a news release on the Park’s website, the International Dark Sky Park certification will give Grand Canyon National Park support to continue to grow its educational programs and will create economic opportunity for neighboring communities as well through astronomy-based tourism.
The certification does not carry legal or regulatory authority; however, it demonstrates a commitment to improving night skies through the use of more energy efficient, sustainable lighting. Certification also reaffirms Grand Canyon’s commitment to educating the public and gateway communities about the importance of good lighting and opportunities to work together toward common goals.
To get this certification from the International Dark Sky Association the park had to show them a certain percentage of the lighting systems were compliant to their standards. And the scale of the operations at Grand Canyon makes this quite a feat. 5,000 lights in the park were surveyed, including their K-12 school. Yep, Grand Canyon has a school!
This process has been a long one. Efforts began in 2016 when the Park was given Provisional status after the initial assessment of over 5,000 exterior light fixtures was taken. At that time 35% of lights were already dark-sky compliant, but the Park had three years to achieve 69%.
In the coming years, the park plans on making 90% of the lights dark-sky compliant. The amount of lights inventoried and retrofitted in this process undoubtedly makes Grand Canyon National Park one of the largest, most complex, International Dark Sky Parks in the world.
Funding for this project came almost entirely from Grand Canyon Conservancy, the official non-profit partner of the park, which relies on donations in order to achieve long-term renovations and educational programming.
