If visitors find locations in Utah’s National Parks, where very little man-made sounds are heard, it can be a breathtaking experience. A park visitor may canoe along riparian habitat and hear a variety of bird calls, or hike a trail and come around a bend to see a few deer jump over the sage-brush.

These types of experiences may also occur after dark when visitors participate in stargazing or a full-moon hikes.

Mark and Sallie Shelton said, “Utah dark skies are our passion! The [dark] sky and quiet solitude are magical. Visitors, from around the world, are in awe when they get their first [heavenly] glimpse of [the Milky Way] and see the stars shining like diamonds on dark velvet.”

Protecting the quiet and darkness of our National Parks has become a priority for many managers and researchers.

Christopher Monz, professor in the Department of Environment and Society in the Quinney College of Natural Resource at USU joined with five other scientists who have all worked on issues of noise pollution and light pollution to compile the book, “Natural Quiet and Natural Darkness: The “New” Resources of the National Park.”

Monz explains, “[We wanted] to compile, in one place, the best science on both the social and ecological dimensions regarding the importance of the resources of darkness and quiet, and the consequences of them slowly disappearing in our most precious protected areas – the national parks.”

The book gathered many interesting findings.

One is the concept of “listening area” which is the distance an individual (human or animal) can hear normal sounds and calls that they’re evolved and adapted to. For a bird species it might be a mating call, for deer it might an alert response from a predator.

As noise increases the listening area may decrease dramatically.

Monz said, “In the United States noise from roads has increased three fold since 1970.”

A three decibel increase in noise results in a 50 percent decrease in listening area. If there is a 10 decibel increase, the result is a staggering 90 percent decrease in listening area.

Monz explains, “If you put noise into the environment there is the potential for significant ecological implications, particularly for wildlife. They can no longer be reliant on the sense of hearing to carry out normal activities…some species will move out of those noisy areas to quieter environments which creates a displacement effect.”

For humans, this means we have less opportunities to engage with the sights and sounds of nature.

One success story outlined in the book occurred in Muir Woods National Monument in California. Monz said, “Simply by putting up signs which raised the visitor’s awareness of the environment they were in, and the importance of quiet for other visitors, the noise decreased by 2 decibels. This gave folks an opportunity to experience better natural quiet environment and a little bit more biodiversity from the standpoint of hearing bird calls from the surrounding forest.”

The book also provides ideas for managing the resource of darkness in the National parks.

Monz said, “Right now 80% of the world’s population lives in locations where there is some compromise of natural darkness…most will never see the Milky Way.”

Cedar Breaks National Monument, which has the highest star gazing site at 10,500 feet, received an award from The International-Dark Sky Association (IDA) for preserving its Dark skies.

The authors of “Natural Quiet and Natural Darkness” hope the book will get in the right hands to provide park managers with this easily accessible tool where they can find the best science and actionable ideas to increase quiet and darkness in our National Parks.

The night sky…throughout history humans have looked up after the sun set in the evening and marveled at the astral bodies spread above them in a sea of black. This sight has inspired people from every age of history and from every culture around the world.

But it’s not the same as it used to be.

For most people, the cycles of night and day are so constant in our lives that we often take them for granted. The rising of the sun in the morning and its setting every evening molds our lives, and has for all of human history. The heavenly bodies we see above us, the sun, moon, planets, comets, and stars, influence all aspects of human civilization, from religion and philosophy to art and poetry. While daytime has remained constant from the beginning to the modern day, the same cannot be said for the night.

Until the end of the 19th century, the setting sun meant a world enveloped in darkness. The night was a time for retreat to homes and hearths, a respite in human activity until dawn. Try to imagine looking up into the night sky from the side of dying campfire ten thousand years ago, or from the step of a frontier cabin only two hundred years ago and seeing the moon and stars as the only source of light around you. Today this universal heritage is quickly being lost to the artificial light emitted by humans across the globe.

It may seem strange to think of darkness as a natural resource, but its importance to life on Earth cannot be overstated. Beyond humans, the billions of plants and animals across the planet have evolved over the eons to their own niche in the day-night cycle. Sunlight, or the lack of it, controls plant and animal behavior, from when to eat or sleep, when to migrate, where to travel to look for food, and even when to reproduce. The artificial light cast by cities disrupts these natural patterns for animals and can lead to hardship and death for many.

Efforts to reduce light pollution are picking up across the country and include everything from buildings and factories shutting off all non-essential lighting during animal migration seasons, to everyday citizens simply turning off outdoor lights when they go to bed.

Despite these efforts however, most Americans in the 21st century are still affected by at least some light pollution and many city-dwellers have never seen a truly dark night sky. Even for those living away from cities, a night sky might be interrupted by sky glow, a phenomenon that occurs when clouds scatter and reflect light back to earth.

Luckily for Utahns however, dark skies might be closer than you think. Utah is home to nine different “Dark Sky Parks”, certified by the International Dark-Sky Association. Among these places are Canyonlands and Capitol Reef National Parks; Natural Bridges, Hovenweep, and Cedar Breaks National Monuments; Dead Horse Point, Goblin Valley, and Antelope Island State Parks; as well as the North Fork area in Weber County. These dark sky parks offer a distinguished quality of starry nights and a nocturnal environment protected for future generations. So whether you are an astronomy enthusiast, an animal lover, or just want to see the night sky as our ancestors saw it for thousands of years, dark sky parks are the place for you.
