A collaboration of night-respecting organizations and individuals working to reverse light pollution in Wisconsin.
Same goal, different angles.
Wisconsin is full of beautiful places and incredible wildlife. A group of people representing different organizations and interests came together in 2025 with one common goal: reducing light pollution in Wisconsin. With our shared interests and unique areas of expertise, we can make a lot of good happen.

Astronomy enthusiasts
Stargazing is a beloved pass-time that brings the wonders of the galaxy down to Earth. Whether individuals are seeking the Northern Lights, constellations, shooting stars, or a full-view tapestry of stars, dark is essential.
Bird lovers
Birding, bird-watching, and feeding birds is a wonderful hobby for anyone, anywhere. Some bird species stay in Wisconsin year-round, but hundreds of species undergo migration in the dark of night to reach their summer or winter grounds. Dark skies allow birds to migrate without being drawn to bright cities and fatal windows.
Energy conservationists
Unnecessary lighting creates significant waste in energy use. By turning of lights or adjusting lighting to be targeted, low level, controlled and warm-colored, we can save up to $3.3 billion in energy usage and 21 million tons of carbon dioxide emissions each year! According to Dark Sky International, installing quality outdoor lighting could cut energy use by 60-70%.
Firefly & glow worm admirers
It’s difficult to find someone who doesn’t love fireflies! Their bioluminescence creates magical flickering of light in prairies, back yards, parks, and river beds. Glow worms produce a similar effect. All of that glowing and flickering is to attract a mate and reproduce. Light pollution interferes with and endangers that process.
Partner Organizations
Park & land trust adventurers
Being apart of a landscape that has been preserved and/or restored to native habitats and functions is one of the greatest privileges a nature lover can enjoy. Light pollution dampens the experience and the natural functions in an ecosystem.
Human health advocates
Healthy sleep involves the production of melatonin, which is reduced or stopped in the presence of light. According to Dark Sky International, “Many studies have shown that exposure to artificial light at night negatively affects human health, including increased risk for: sleep disorders, depression, obesity, diabetes, heart disease, and even cancer.
