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.

Yellowstone Elk’s response to Wolves

Arguably the most scientifically-important (and controversial) elk herd in the world, because it has been scrutinized and studied the longest, is in Yellowstone National Park.

The first professional study of the herd was started in 1916 and the herd has been at the center of debates about the forces that shape wildland ecosystems ever since.

In addition to providing insight into ecosystems, the Northern Yellowstone elk have been an important source population for restoring other elk herds in the United States and Canada where they were eliminated during the late 1800s. Many elk herds in North America trace their ancestry to translocated elk from northern Yellowstone.

The herd has a seasonal migration route that stretches from the Paradise Valley in southwest Montana to the southern boundary of Yellowstone National Park – a distance of 80 miles.

Prior to the Yellowstone’s establishment in 1872, market hunting decimated the elk herd, reducing it to a few thousand animals. Through the 20th century the population gradually grew and in 1994 it reached a peak of over 19,000.

A year later, the first of 41 grey wolves were reintroduced to Yellowstone.

People wondered what impact these wolves would have on the Yellowstone herd since elk are the main source of food for the canines.

Dan MacNulty, associate professor in the Department of Wildland Resources in the Quinney College of Natural Resource at USU, who has been studying Yellowstone wolves for the past two decades said, “people were concerned wolves were inducing a landscape of fear which was changing the way elk were using their habitat.”

They imagined the poor creatures hiding in less than ideal habitats because they had been chased off by the wolves.

However, studies conducted by MacNulty and others have since revealed that elk continue to maintain regular access to all their usual habitats irrespective of wolves. In one recent study, for example, MacNulty and his team found adult female elk established and maintained winter home ranges without regard to several measures of wolf predation risk including the density of wolves and the risky areas where wolves often kill elk.

Elk coexist with wolves in a variety of ways. One way is elk use the riskier areas of the landscape when wolves are resting, which is in the afternoon and, surprisingly, at night. Wolves don’t have ideal vison for nocturnal hunting, so they often settle down after sunset and resume hunting at dawn. These nightly lulls in wolf activity allow elk to graze the open grasslands in relative safety.

But even when wolves are on the prowl, elk don’t seem to go out their way to avoid them. MacNulty’s recent study found the rate at which elk encountered wolves was no different from what was expected if elk simply ignored wolves. This is possible because elk often survive their encounters with wolves, owing to their larger size, aggressive demeanor, and herding behavior. As a result, elk seem to place greater emphasis on finding food than on avoiding wolves.

The emerging picture is that the effect of wolves on the northern Yellowstone elk herd is defined by wolves eating rather than scaring elk. How much this consumptive effect actually matters for elk population growth is the focus of ongoing research. One clue that it may not matter too much is the elk population has been steadily growing since 2012.

MacNulty cautions that we should recognize the complexity of the Yellowstone ecosystem and resist the urge to jump to conclusions, and instead rely on patient data-gathering to test what may seem obvious.

Nature can be full of surprises.

Our Invasive Phragmites

Those unfamiliar with the history of the Utah’s wetlands may see Phragmites and say, “What a beautiful, elegant plant! It looks so graceful blowing along the shore.” Our Invasive Phragmites
However, the plant’s attractiveness and ability to absorb pollutants may not compensate for its negative impacts.

Phragmites is an invasive perennial grass that now thrives in much of the wetlands around the Great Salt Lake and other marshes in northern Utah. It grows in dense clusters and normally reaches 5 to 10 feet in height. If the conditions are right it can reach 15 feet.

The patches of grass are so dense that wetland managers are called out each year to rescue duck hunters – who are lost in the Phragmites.

Karin Kettenring, associate professor of wetland ecology in the Department of Watershed Sciences at USU and her research team have been studying Utah Phragmites for the past decade.

Kettenring explains why Phragmites is a concern, “We fear it is fundamentally changing the habitat of Great Salt Lake wetlands which are renowned for being a home for migratory birds including waterfowl and shore birds.”

The exotic grass most likely started in the Great Salt Lake wetlands after the flooding of 1983. The flood washed out the marshes. When the water levels receded, the salty water had destroyed all the native vegetation in the wetlands. Phragmites then moved in. By 2011, the exotic grass had spread over 24,000 acres.

Scientists believe humans inadvertently brought Phragmites to Utah, since birds don’t migrate East and West, and the birds usually don’t eat the seeds. Someone’s boat may have transported the seeds into Utah. They sat dormant in the soil until the conditions were perfect, then the spread of Phragmites began.

Today an average small patch of Phragmites, about 20 feet square, can spread a couple yards a year just from the stems it sends out above and below the ground. However, research has shown it’s not the stems that cause the most reproduction – but the seeds.

Karen Mock, associate professor in the Department of Wildland Resources and a long-term collaborator on this project helped Kettenring with the genetic work.

They tested the genetics of a lot of Phragmites pulled from the same patches and found many different genotypes – proving the plants came from different seeds, not the stems of neighboring plants.

With these results, Kettenring’s lab discovered the best way to control the invasive grass is to first control the seed production by mowing the grass mid-summer to keep it from spreading. Then in the fall spraying the area with herbicide three years in a row. An herbicide approved for use in wetlands can be used – such as Rodeo.

If the Phragmites has been there only a few years then the seeds of the native vegetation will still be in the soil, and they’ll come back on their own.

However, if the Phragmites has been there for a long time then re-seeding of native plants will be necessary.

To determine the best way to re-seed wetlands, Kettenring partnered with Utah Division of Wildlife Resources, Utah Division of Forestry, Fire & State Lands and David England – one of Kettenring’s past graduate students. England has spent extensive time in the lab determining how to help seeds germinate.

Emily Martin, Kettenring’s current graduate student will also help with the UDWR reseeding as she searches for techniques to make seeding more effective.

Ultimately their goal is to restore native plant communities to keep Phragmites from coming back and restore habitat for important migratory birds.

Outlying wolves of the Northern Rocky Mountain population occasionally wander into Utah, but seeing one is rare. If you want to increase your chances of viewing one of these majestic beasts, the best place to go is the northeast corner of Yellowstone National Park.How to find Wolves in Yellowstone

For over six decades, wolves were missing from Yellowstone’s ecosystem. But on a cold January day in 1995, eight gray wolves from Canada were released in the park in an effort to restore the predator to this native habitat.

Before their release, wolves were the only indigenous mammal missing from the Park. The last pack of wolves were killed in the 1920s.

The Park is now one of the few ecosystems in the temperate world to have the same mammals wandering around, as it had hundreds of years ago.

Today, approximately 88 wolves live in Yellowstone.

Finding one of these gray wolves is challenging, but if a person knows where to look, with the right equipment, the chances increase considerably.

Nathan Varley, a naturalist guide with Yellowstone Wolf Tracker says, “Wolves are usually spotted from long distances, using high quality optics. Recently, I guided a group that had their first wolf sighting over two miles away. We patiently watched the pack of 11 wolves move until they were less than a mile away.”

“The pack encountered a bison herd and attempted to single out a calf. The herd rallied, surrounding the calf so the wolves couldn’t get to it. Snow began to fall so we lost sight of the hunt, but learned later the pack was unsuccessful. We found them the next day, many miles away.”

Before arriving in Yellowstone, visitors may want to learn how to distinguish coyotes from wolves.

Rick McIntire, who researched Yellowstone wolves with the U.S. Park Service since 1995, explains, “In a given wolf pack territory which may be 300 square miles, there could be 10 coyote packs. So the chances of visitors seeing coyotes before wolves is high.

McIntire gives the following tips for identifying coyotes and wolves:

“It may be hard to tell smaller wolves from bigger coyotes. One thing to look for is coyotes have big ears and narrow jawlines like a fox, whereas wolves have ears that are proportional to the size of their heads, and strong stout jaws.

Their vocalizations are also different. Wolves have a deep howl, while coyote’s howl has a high pitched tone.

The wolves color may also help. Roughly half of Yellowstone wolves are black and since coyotes are never that dark, if you see a group of canines and one of them is black you have found a wolf pack.

The best place to begin the search is the northeast corner of the park at Lamar Valley – the “Serengeti” of the Yellowstone. Many prey gather here, which attract the large predators like bears and wolves.

Once you arrive, find an appropriate place to park, set up your viewing equipment close to your car, then settle down for a relaxing couple hours of observation. Patience often pays off, so be alert.

Daniel MacNulty, associate professor in the Quinney College of Natural Resource at USU, who has been studying the Yellowstone wolves for the past two decades said, “Watch for prey standing alert looking at something, follow their gaze, they may point you directly to a wolf pack.”

So if you’re ready to find one of these majestic beasts, gather some family or friends, your high quality optics – and head north. The northern road in Yellowstone which passes Lamar Valley is open all year long, so you won’t have to wait till spring.
