Habitat Heroes Explore More Utah Biomes

Utah is a wildly diverse place. Ecological and biological diversity are usually tied to an abundance of water; but here in Utah, despite our relative lack of the wet stuff, we boast of at least nine unique biomes spanning from the low-elevation Mojave Desert around St. George to the high Alpine Tundra of our many snowcapped mountain ranges. You can think of a biome as a large community of similar organisms and climates or a collection of similar habitats. Just recently, my third grade students wrapped up a semester-long investigation into seven of those biomes found in Utah including the high Alpine Tundra, Riparian/Montane Zone, Sagebrush Steppe, Wetlands, and the Great Basin, Colorado Plateau, and Mojave Deserts. We explored those biomes by way of researching a specific animal endemic in Utah to each of those biomes. We called our project “Habitat Heroes.” I’ll let a few of my students explain their findings.

Noah’s Ringtail:
This is Noah, and I’ve been studying the ringtail. The ringtail lives in the cold desert biome on the Colorado Plateau in Utah. The ringtail is gray and furry with a long black and white tail. How ringtails catch their food: number one-being very sly and waiting for the right time. They live in rocky deserts, caves, and hollow logs.

The Muskrat:
My animal’s the muskrat. The muskrat lives in the wetland biome in Utah. Muskrats live in Mexico, Canada, and the United States where there are marshes, ponds, and vegetated water. Muskrats go out at night and find food like aquatic plants, grass, and fish. They have special abilities that can be used for a very special reason to help them survive.

Elizah’s Weasel:
My name is Elizah, and my animal is the long-tailed weasel. The long-tailed weasel lives in the Great Basin biome in Utah. They are brown and yellow all year long except for winter. They are white during winter. [The] long-tailed weasel’s scientific name is Mustela frenata. They are mostly nocturnal.

In addition to researching the different biomes and learning about the adaptations animals must possess in order to survive there, these third graders have been visiting the several biomes local to Cache Valley and investigating their research animals’ habitats. These experiences have been powerful in helping students realize what it’s really like to exist in the wilds of Utah.

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.

We can be part of the problem, or part of the solution. It is a marvel at how some people have an “ I don’t care” attitude when it comes to the outdoors and the natural world. Whether a person believes that God created the world, it happened via evolution, or never really think about it at all, our lives are directly connected to the natural processes of this planet.

For those who live in the somewhat hectic world of urban employment and the frantic rush of crowded traffic lanes, it may seem that there may never be a moment where they can relax and enjoy the quiet sounds of nature, whether it be the ripples of a stream, the calls of a songbird, or the breeze rustling through trees. We can become so disconnected from nature that its very existence may seem like a foreign land to us as we are absorbed by work, television, transportation, and household bills.

Then again, you might be the type to schedule an occasional escape to a national park or forest. Or perhaps you will be content simply to bid farewell to Winter and welcome the warmth of Spring, the sounds of songbirds claiming territories and seeking mates, or watching gorgeous butterflies drifting among floral bouquets. But what if some of those natural sights and sounds we seek are no longer there?

In 1962, Rachel Carson published her book, Silent Spring. Think about that title: Silent Spring. What would it be like to walk outside and never hear the songs of birds or the humming of pollinating honeybees?
Carson was concerned about the harmful effects of pesticides on the environment, especially those being sprayed to control insects on large scales. She was concerned about the near constant presence of such chemicals in our foods and suggested that these products are cancer-causing. And, in certain cases, many insects were developing resistance to new pesticides. Her recommendations were that people use biological controls whenever possible by using natural predators, such as ladybird beetles to attack aphids, rather than spraying for them.

Humans have developed powers to change our environment in wonderful, or drastic, ways. We need to remember that whether we think about it or not, we are connected to the “natural” systems that support human life.

So let’s consider a few ways that we can help ourselves by helping those natural systems.

First:

Protect your soil. Be careful about chemical additives and fertilizers.

Second:

Be prudent about your use of water. It is essential to all life, and we don’t have an unlimited supply.

Third:

Reevaluate your affinity for lawns. Their value in the West is overrated. Consider planting more native flower gardens that will feed the pollinators which help provide our food sources.

Fourth:

Plant trees. They provide shade, purify the air, provide housing for birds, and raise our property values.

Fifth:

Help wildlife. Plant milkweed for declining Monarch Butterflies, place birdfeeders in your yards, and provide a water source for birds and butterflies.

We can be part of the problems, or part of the solutions.

A Nuthatch In Three Varieties

Inverted woodpecker, a phrase I use to describe the feeding habits of the amazing nut hatch family. I first became aware of this lovely little songbird growing up in Michigan, where the white-breasted nut hatch was common fare in the north woods. Their little laughing notes were most welcome as I sat on my deer stand where I would watch them search bark crevices for yummy morsels of grubs, insect eggs or seeds they had wedged in for tomorrow’s snack.

Now having lived many years in Utah, it is the red-breasted nut hatch that has replaced this eastern cousin for the most part. Their “yank, yank, yank” vocalizations light up my life whenever and wherever they occur. They prefer conifers but will gladly substitute a deciduous tree, especially those with more furrowed bark. Where there is food or water, infrequently a white-breasted will appear, especially in our higher elevations, although I’ve had them join the red-breasted at our feeder during winter months – a rare treat.

If one spends much time in our Ponderosa pine forests in central and southern Utah, another family member can be found. Unlike the other two more solitary species, these tiny pygmies occur in small flocks and are very chatty. Highly social, the pygmy nut hatch appear to enjoy a food frolic as they fly from tree to tree for feeding and social interaction. Thus, Utah’s blessed with all three North American species of nut hatch.

If you observe them as they search the main stem of a tree, my inverted woodpecker title will be justified. Rather than moving from top to bottom of the tree facing up as do the woodpeckers, the nut hatch prefers head down from top to bottom. They also like hanging upside down on a horizontal limb. Why? Evolution keeps us mysteries well-guarded. I conjecture partitioning might be part of the answer: a phenomenon where bird species will utilize different parts of the tree to avoid competing for resources with other species.

As with all of life, I pay attention to how our shifting climate has been observed or predicted to affect their populations and distribution. As long as there are conifers breeding season, nut hatches are content. They can be found in dry Ponderosa pine foothills, in moist boreal bogs, around tree line in the mountains, and even in planted Christmas tree plantations. Audubon’s seven-year generated climate model shows an overall northward drift of the species’ range with more disruption and range loss in summer than in winter. The nut hatch is a habitat generalist in winter, so summertime climate is the chief concern going forward. However, whether the species adapts in the decades ahead will be determined in large part by the conifer forest health in a changing climate. The projection for species range change from 2000 to 2080 is 19% of summer 2000 range remaining stable and 58% of winter range projected to be stable. It’s my plan to follow them wherever they may go.
