Ron Describes Exotic Invasive Species

Exotic invasive species. “Exotic”, sounds rather alluring, but “invasive” implies something completely different and undesirable.

Basically, we are referring to any species that is not native to that ecosystem, it can survive and reproduce there, and by its introduction can cause harm to the environment, the economy, wildlife, and human health. And this doesn’t mean just plants. There are also invasive animals and even microorganisms that can disrupt the balance that maintains natural ecosystems.

They usually have some means of dominance over native species, such as superior reproduction or faster growth success. They may also have unique forms of defense against native predators. Being newly introduced to an area, they may not even have any competition from similar species, or natural predators may not exist in their new area at all. Their advantages can outcompete native species at alarming rates and result in a reduction, or elimination, of biodiversity in huge areas. And research has proven that having a diversity of native life forms improves the health of ecosystems.

Organizations dealing with agriculture, forestry, fisheries, wildlife and waterways estimate that the annual costs to try to control invasive species in our country exceeds $120 billion dollars. And, whether you are a supporter of the Endangered Species Act or not, a quote from the U.S. Fish & Wildlife Service states “More than 400 of the over 1,300 species currently protected under the Endangered Species Act,…..are considered to be at risk at least partly due to displacement by, competition with, and predation by invasive species.”

In Utah, there are 596 invasive plant species, 28 invasive insects, and a few mammals too. I’ll simply mention a few and why they are so problematic: In the water we are plagued with Quagga and Zebra Mussels, Carp , and plants like Purple Loosestrife. One adult Zebra Mussel can produce one million larvae that mature in one year.

Africanized Honeybees have been sneaking into our State, and they can be very aggressive.
Some of the more common invasive plants include: Russian Olive, Field bindweed, Dyer’s Woad, Russian and Canada thistle, Stinging Nettle, Tamarisk, …..even Kentucky Bluegrass is on the list. The yellow Dyer’s Woad plant that covers many of our hillside grazing lands, is prolific and may produce 10,000 seeds per plant

The European Starling and English House Sparrow are two birds that don’t belong here, but have been extremely successful by inhabiting all 50 States and occupy nesting sites and deplete food sources of our native American songbirds.

Mammals include the Red Fox, Muskrat, White-tailed Deer (which might excite some hunters), and the adorable Raccoon which may be one of the best examples of the problems invasive species can cause. Raccoons can damage homes, fruit trees, and gardens, kill chickens, cats, migratory birds, pheasants, ducks, quail and grouse. They can also spread disease to other mammals as they eat out of garbage cans, carry fleas, ticks, lice, distemper, mange, and blood tests have shown that 80% of them have been exposed to rabies as indicated by the presence of a rabies titer.

The Henry Mountains’ Bison Herd

The Henry Mountains of southeast Utah are famous for being the last mountain range in the contiguous United States to have been officially mapped. Indeed, before they were mapped, they were often referred to as the “Unknown Mountains.” Another relative unknown detail about this range is that it harbors one of only five genetically pure, free roaming bison herds on North American public lands.

In 1941, a seed herd of 18 American Plains Bison (B. b. bison) were transplanted from Yellowstone National Park to the arid desert of Utah’s Robbers Roost. A year later, five more bulls were introduced to the herd in hopes of sufficiently diversifying the gene pool and sustaining the herd. The bison must not have found Robbers Roost as appealing as Butch Cassidy had, though, because this new Wild Bunch set out for literal greener pastures that very same year.

The small herd forded the Dirty Devil River and travelled southwest toward the Burr Desert. The herd stopped here for a while, enjoying their newfound buffet atop the Aquarius Plateau. 21 years later, though, in 1963, the still small herd grew tired of the desert and abandoned it altogether for the higher, more verdant snow fed meadows of the nearby Henry Mountains. Here, the herd thrived and quickly swelled in numbers.

Today, the herd’s population is estimated to be between 300 and 400 animals, which ecologists and wildlife biologists regard as the maximum carrying capacity of their Henry Mountain range. The Utah Division of Wildlife Resources has responded accordingly. In an effort to perpetuate the health of the herd and their range, the DWR began issuing “Once-in-a-lifetime” permits to hunters hoping to fulfill not only a tag but also a burning sense of adventure. The Henry Mountains, after all, were mapped last for a reason. They remain one of the most rugged and remote places in a state known for its rugged and remote places.

Fittingly, quite unlike their more quintessential Plains Bison brethren, the Henry Mountains bison can be found almost anywhere in the Henrys between the desert lowlands and timberline. Apparently no one has told the herd that Plains Bison don’t typically like high elevations or steep mountain slopes. This unique proclivity of the Henry Mountains herd to cast off behavioral stereotypes works in their favor when hunting season rolls around and they abandon the high, open meadows for steep, wooded canyons and thick groves of aspen and evergreens.

This highly adaptive nature unique to the Henry Mountains herd made it an obvious candidate to serve as a seed population in early 2010 when 39 individuals were transplanted from the Henry Mountains to the Book Cliffs along the Utah-Colorado border. These 39 animals were to serve as a genetic supplement to a relatively new herd first reintroduced to the Book Cliffs by the Ute Indian Tribe in 1986. The now 600-strong Book Cliffs herd is well on its way to reestablishing the American Plains Bison’s historic range in the Book Cliffs.

The story of the Book Cliffs and Henry Mountains Bison give us reason to hope that one day soon, the American Bison might reclaim its territory, a historic range that once ran from Alaska through the Canadian territories and the Great Plains to the Eastern Seaboard and the Gulf of Mexico. And, if so, the role the Henry Mountains herd will play in that expansion may be a significant one.

Clark’s Nutcracker

Skiing a few miles into a lovely northern Utah canyon in frigid, single digit temperatures I was startled by an abrasive sound rolling down slope from a thick cover of conifers. A Clark’s nutcracker! My spirits were warmed by several degrees.

Lewis and Clark have left their names on many plants and animals in our western mountains. The Clark’s Nutcracker, a member of the jay family, has a long list of special attributes well beyond the norm.

This “forester bird” has planted countless millions of trees from Canada to Mexico, provided food for many other critters including the mighty grizzly bear, and has amazed animal behaviorists with their uncanny recall ability.
Nutcrackers often bury their seeds at the perfect depth for germination. They bury pine seeds in hidden caches in fall, then re-find them during winter, allowing them to nest in late winter, when the forest is still covered with snow. They bury clusters of four or five seeds per location caching up to 500 seeds per hour. They often hide seeds near the base of tree trunks, a tendency that may play an important role in their spatial memory system. Landmarks help nutcrackers remember the precise locations of caches.

By the end of the fall, each nutcracker has stashed tens of thousands of seeds. Clark’s spend so much time hacking apart pinecones that sticky resin sometimes dyes their grey feathers a reddish-purple color. But the prize is worth the effort: Pine seeds are a nutritious food, packed with fats, proteins, and carbs.

Crucially, the birds will hide seeds as far as 20 miles away from their source trees. In doing so, they help trees expand their territory into new areas. As development continues to fragment forests and climate change demands rapid migration, “animals that move between patches of habitat are increasing in importance.

Other feeding habits include catches flying insects in the air, digging insect larvae out of wood, eating berries, insects, snails, eggs, carrion, and even young of other birds, which I observed directly near White Pine Lake in the Bear River range. Knowing them as a seed eater, I stunned to watch as a mixed flock of forest birds mobbed the Clarks who had a youngster in its beak it had plucked from its nest.

Nutcrackers have an especially close relationship with the whitebark pine. Unlike other pines, whitebark seeds don’t have “wings” that let them ride gusts of wind across the landscape. Instead, the seeds and cones seem optimized for a nutcracker’s bill, and as such, the trees rely on the birds’ forgetfulness to reproduce. It’s possible that the birds could play a part in helping the whitebark pine recover. Human foresters are now studying how to attract Clark’s Nutcrackers to aid in forest restoration.

Climate change is forecast by Audubon’s climate model to decrease winter and summer range by roughly equal amounts—around 70 percent by 2080. Tied as this species is to the high western coniferous forests, it seems unlikely it will be able to adapt to any new shifting climate space, as is true with another favorite subalpine resident- the pica, a miniature member of the rabbit family.

This time of year, we see a cast of characters flying among the trees and bushes as they search for food and a place to nestle to conserve warmth and energy.

Another member of the cast is the Dark-eyed Junco, a medium-sized American sparrow with a neat-flashy look. It has solid slate-grey feathers over most of its body except for its pink sides and white underbody. The Junco is found throughout the United States, Canada and Mexico.

The third cast member is the Red-breasted Nuthatch which has a pale red chest, grey wings and a black feathered head with stripes of white below and above the eyes. Its tail is short, its bill is long and it’s one of the few birds that climbs headfirst down trees.

All three birds find the majority of their winter nourishment from nuts and seeds, since most insects are hiding in dormancy or are dead.

When a harsh winter hits and heavy snow fall covers their natural food source, the birds can rely on bird feeders to find nourishment.

Although winter bird feeders are beneficial, some Utah residents may hesitate putting out nuts and seeds for the following reasons:

One, they worry the birds may become dependent on the feeders.

Clark Rushing, assistant professor in Department of Wildland Resources in the Quinney College of Natural Resources at USU explains, “In a typical winter these birds don’t need the extra food from a bird feeder to make it through the winter, but…when the snow covers up their [natural food source] they rely on the feeders which increase the birds’ survival rate over the winter. When [snow] conditions [return to normal]… they go right back to feeding on natural sources.”

Another concern some Utah residents have is if the feeders will impact the birds’ migratory behaviors. They worry species who normally migrate might stick around for the winter because they found food.

Rushing says, “This is not a huge concern because most of these bird species use photo period as a que to migrate, which means they start migrating in the Fall when the days start getting shorter and food is still relatively abundant – so food is not the que that these species use to migrate.”

When starting the hobby of winter bird feeding, there are a few good tips to remember.

First, is the importance of keeping your feeders clean. Some diseases can be spread by bird feeders, so keeping them clean is essential.

According to Rushing, “The recommendation is to take [a feeder] down every two weeks, empty it and give it a light cleaning. [Avoid using] harsh detergents. If you see evidence of mildew or mold then a diluted bleach mixture, which you then rinse off, can be really beneficial. Let the feeder completely dry before you put bird seed in it. When [the feeder is wet] is when you have the most problems, so keep it dry.”

Having a variety of feeders and foods is the best way to attract an assortment of birds to your yard during the winter months.

Rushing adds, “The great thing about bird feeding is it connects people to wildlife.”

It’s one of the few ways you can enjoy watching wildlife out your own dining room window throughout the cold winter months.
