One of the first things observers notice about the kit fox is its tiny size. Weighing in at a mere four pounds or so, Vulpes macrotis is among the smallest canids on the planet.

Often mistaken for swift foxes, kit foxes are a distinct species that sport larger ears and a leaner, more angular appearance. The small mammal has a long, black-tipped bushy tail and a yellowish-gray coat tinged with rusty orange.

Listed as a sensitive species in Utah, the carnivores live primarily in the state’s arid, western regions, where they reside in family dens and hunt for smaller mammals such as field mice and jackrabbits, as well as insects, birds, amphibians and fish.

But the diminutive hunter is susceptible to predation by a host of larger beasts, including coyotes, bobcats and golden eagles, says USU alum and wildlife biologist Bryan Kluever.

“With small size comes disadvantages; however, the advantage is increased agility and mobility,” he says.

Kit foxes have little difficulty leaping over sagebrush and rabbitbrush that towers over them and provides a welcome refuge from hungry predators. Given a choice, the foxes prefer to stay in open areas, where they can put their sense of sight to full use. Their vulnerability to larger members of the food chain partially explains the animal’s nocturnal habits.

“The life of a kit fox is ruled by the night,” Kluever says. “They are rarely active during the day and, when they are, this activity is limited to near dawn and dusk. This behavior is likely a function of eluding their enemies and avoiding harsh desert temperatures, especially in summer.”

One of the kit foxes’ most distinctive traits is its insatiable curiosity.

“If one word had to be used to describe the kit fox, it would be inquisitive,” says Kluever, who extensively studied the creatures at the Army’s Dugway Proving Ground. “Most canids cannot be captured with cage traps but kit foxes are one of the exceptions. When we released them after capture, they often began to walk toward us, rather than running away.”

The Great Salt Lake

There is a giant among us with a profound influence on our past, present, and future. My first encounter with this giant was both buoyant and delightful as I floated in the brine on a lovely summer day. But I was oblivious to the Great Salt Lake’s immense value as an environmental, cultural, and economic resource.

Much of what follows is taken from a very recently released collaborative study titled “Impacts of Water Development on Great Salt Lake and the Wasatch Front” which was a collaborative effort from four institutions(Utah State University, Utah Division of Water Resources, Salt Lake Community College, and the Utah Division of Wildlife Resources.)

A 2012 analysis by Bioeconomics estimated the economic value of the lake at $1.32 billion per year for mineral extraction, brine shrimp cyst production, and recreation. The abundant food and wetlands of the lake attract 3 million shorebirds, as many as 1.7 million eared grebes, and hundreds of thousands of waterfowl during spring and fall migrations. Because of this, it has been designated as a Western Hemisphere Shorebird Reserve Network Site. Due to its enormous surface area, it produces the “lake affect” which enhances our snow pack by an estimated 8%, a significant amount for both skiers and our available water. But our giant is shrinking.

Since the arrival of 19th Century pioneers water diversions for irrigation have decreased its elevation by 11 feet exposing much of the lake bed. Natural fluctuations in rainfall and river flow cause the lake level to rise and fall, but there has been no significant long‐term change in precipitation and water supply from the main tributaries since their coming in 1847.

For the first time since it was opened in 1984, water has stopped flowing through the Great Salt Lake causeway breach, an area that allows water to travel between the southern and northern parts of the lake.

To significantly reduce water use, a balanced conservation ethic needs to consider all uses, including agriculture, which consumes 63 percent of the water in the Great Salt Lake Basin. There are no water rights to protect our Great Lake, so water development currently focuses solely on whether there is water upstream to divert. If future water projects reduce the supply of water to the lake, (such as the Bear River Development Project, its level will (most likely) continue to drop.

We must look beyond the next few decades and decide how we value the lake for future generations. Lower lake levels will increase dust pollution and related human health impacts, and reduce industrial and environmental function of Great Salt Lake. We must be willing to make decisions now that preserve Great Salt Lake’s benefits and mitigate its negative impacts into the coming centuries.

John Muir, one of my favorite early American naturalists would most certainly agree with me. From his baptismal plunge into the Great Salt Lake. “I found myself undressed as someone else had taken me in hand and got myself into right lusty relationship with the brave old lake. I was conscious only of a joyous exhilaration….”
And where else could John and I have such a wonderfully buoyant experience?

Shrubby-Reed Mustard: The Best Little Plant You’ve Never Heard of

Tucked into isolated pockets of the Uintah Basin’s arid wildlands is the best little plant you’ve never heard of. Known to exist only in Duchesne and Uintah Counties, Shrubby-reed Mustard seems to occupy only the semi-barren “islands” of white shale in areas of the Green River Formation’s Evacuation Creek region. The endangered plant features thick, almost succulent, blue-green leaves and small yellow flowers.

“The habitat of Shrubby-reed Mustard is visually striking,” says USU alum Matt Lewis, a botanist with the Bureau of Land Management in Vernal, Utah. “It grows in very shallow, fine-textured soils and shale fragments that form narrow bands in the desert shrub community.”

Among the first plants to flower in spring, the perennial herb is visited by large number of insects, including many native bee species that forage for pollen. Scientists believe these bees may be critical in the plant’s reproduction and survival.

Lewis says the plant, also known as Toad-Flax Cress and Uintah Basin Waxfruit, offers an understated beauty to the stark landscape. With a shrub-like form and multiple stems, Shrubby-reed Mustard grows to about 20 centimeters in height. Its leaves, which feel almost like leather, change to a bright purple in the fall.

The plant is also enticingly fragrant, Lewis says. “Its scent reminds me of roses mixed with apples and pears.”

Despite its fragile status, Shrubby-reed Mustard is a long-lived plant. USU ecologist Geno Schupp says some individual plants may be one hundred years old.

The elusive species has outlived scientists’ attempts to classify it and has undergone several taxonomic changes. It currently boasts the scientific name Hesperidanthus suffrutescens, placing it solidly in the mustard family.

Lewis knows of no history of Shrubby-reed Mustard as a culinary or medicinal herb, though documented reports of such uses for mustard plants date back to ancient times. The plant appears to provide welcome forage for some four-legged creatures, he says, as he recently witnessed plants that had been grazed completely and ripped from the ground.

“Whether that was due to livestock or native ungulates, I’m not sure.”

Utah’s Stunning Landscapes and America’s Celebration

Utah is arguably blessed with the most stunning landscapes on the planet. Many have been preserved for posterity in our National Parks & Monuments. This is the BIG YEAR- the 100 year anniversary of the National Park Service! I’ve sampled and worked in many of them- from Alaska to Florida, from S. California to New England. As many would suggest- our National Parks are one of America’s greatest achievements which has gone global, now found on all continents except Antarctica (or am I missing one!).

Much of my work in the Parks has been assisting with the launch of the “Climate Friendly Parks” program which began in 2006. The program provides parks with the tools and resources to address climate change and ensure the most sustainable operations across the agency.

National parks, because of their location and unique, protected resources, are places where the effects of climate change are particularly noticeable. With the establishment of the National Park Service in 1916, responsibility was given to the Service to preserve and protect the significant resources within parks for the enjoyment of current and future generations. Today, as knowledge about climate change and its effects increase and potential impacts are better understood, the need to practice good stewardship and develop forward thinking resource management plans is more relevant than ever.

I began in Zion N.P. then moved on to several others including Mt. Rainier, Olympic, Rocky Mountain, and Denali in Alaska. Zion N.P. will always be at or near the top for its amazing landforms, shear grandeur, hidden canyons, and rich diversity of life- the highest in Utah.
It was here that I first met the ringtail cat and Mexican Spotted Owl- two illusive, iconic critters. Both appeared in broad daylight in Hidden Canyon on the west face of the Great White Throne. There is no season less than spectacular here. Perhaps the most dramatic accompanies the seasonal monster thunder storms amplified by massive sandstone cliffs which begin spouting 2000 foot blood red waterfalls. It’s all too surreal, too ethereal for one’s senses to fully grasp.
And yet another proposed stunning Utah landscape containing thousands of ancient ruins is receiving wide citizen support including many native tribes, that being the Bears Ears NationalMonument.

This area of South Eastern Utah offers a unique opportunity to include the “real Americans”, the people that have over 10,000 years of Utah history, who continue to honor and worship this ancient landscape of their ancestors. These tribes have been invited to participate in its planning and management to assure their rituals and subsistence ways may continue, and that its pristine nature would be preserved in perpetuity.

Designation of the Bears Ears NM would be a marvelous celebratory note for this epic year to honor America’s grandest idea!
