Construction on a ring road south of Calgary could end up impacting two unexpected groups — wildlife and scientists.

Street lights that will be part of the project could end up ruining the dark skies needed by both the Rothney Observatory and the Ann and Sandy Cross Conservation Area.

The conservation area is one of the first nocturnal preserves in Canada, where dark skies help preserve natural processes.

The observatory near Priddis has been part of the landscape south of Calgary since the 1970s, but as the city grows, supporters fear its days are numbered.

The observatory is operated by the University of Calgary and scientists say important work could be impacted by light pollution.

Dark sky supporters told CTV they will start a sign campaign south of Calgary to raise awareness of the issue.

“We tend to be overzealous in our use of light and I think that educating people about why we need light and using it smartly will reduce the amount of light people employ and will add years and years and years of longevity to the observatory,” Phil Langill, University of Calgary astrophysicist said.
