Get Involved With Plans To Manage Yellowstone National Park’s Bison

Talk about iconic species at Yellowstone National Park and you’ll most likely start with bison. So tightly are these animals tied to the national parks that they’re even on the Interior Department’s emblem.

But Yellowstone bison also are controversial. Many of these shaggy animals head out of the park in winter and roam into Montana. That can be a problem, as some in Montana’s livestock industry fear bison will transmit brucellosis — a disease that can cause cows to abort their fetuses — to their herds.

Since 2000, the Interagency Bison Management Plan has governed how the park’s bison will be managed in and out of the park. Now state and federal agencies with connections to Yellowstone are working to craft a new approach.

Everything likely will be on the table as that effort moves forward, including the park’s work to maintain its bison population at a specific number.

The National Parks Conservation Association along with other regional and national organizations earlier this spring sent a letter to Montana Governor Steve Bullock and Yellowstone Superintendent Dan Wenk outlining important areas of consideration for the development of the new plan.

Those groups hope a solution can be found to killing hundreds of bison that leave the park during the winter months.

Caroline Byrd is executive director of the Greater Yellowstone Coalition. She says the effort to craft a new management plan “offers the opportunity to improve, update and shift the management of Yellowstone bison and reduce the annual cycle of controversy and conflict that has characterized the public debate regarding bison management for too long.”

A new management plan, she says, should be “rooted in science, reflect the changes that have occurred in the past decade, incorporate our knowledge and experience managing bison, and chart a new course for bison conservation and management that is good for bison, good for Yellowstone National Park, good for the State of Montana…”

You can lend your thoughts to the process, too, as a public comment period on aspects that should be covered in an environmental impact statement are being accepted into June.

Utah streams offer excellent year-round fishing opportunities for every level of angler. According to the Department of Natural Resources, Utah’s waters are home to approximately 80 different species of fish, but it is the trout fishing that is the biggest attraction for fishermen. Of the trout species swimming in our rivers and lakes, the cutthroat trout is a local favorite and the only trout native to the state.

The cutthroat trout represents the most diverse trout species in North America. They are a freshwater fish of the Salmonidae family that live in cold, clear streams and lakes across the west. Cutthroat trout are distinguished from other trout species by two red slashes prominently striping the lower jaw after which they are named. All cutthroat trout share a single common ancestor, but historic population isolation gave rise to 14 subspecies, each endemic to their own geographic region and river drainage.

There are four subspecies that exist in Utah. Only three of these are considered native to the state: the Colorado River cutthroat, the Yellowstone cutthroat, and Utah’s state fish, the Bonneville cutthroat. In Utah, the Colorado River cutthroat trout can be found in some of the smaller streams and tributaries of the Green River, the San Juan River, and the Colorado River drainages. Their bright coloration and posterior black spotting distinguish these cutthroats from others.

Pure, native Yellowstone cutthroat trout are present in small numbers in the streams of the North Slope of the Raft River Mountains in northwestern Utah. However, this subspecies is more widely distributed across the state due to extensive stocking. Yellowstone cutthroat trout can be differentiated by larger-sized black spots concentrated near the tail and their gold, gray, and copper tones.

The Bonneville cutthroat trout evolved in the Bonneville Basin of Utah, Wyoming, Idaho, and Nevada. Its primary ancestors were a population of lake dwelling cutthroat trout living in the late-Pleistocene aged Lake Bonneville. The Bonneville cutthroat trout is less vividly colored and has spots that are more sparsely and evenly distributed across the body than other cutthroats. Thought to be extinct in the 1970s, populations of the Bonneville cutthroat trout are now estimated to exist in around 35% of their historic range, including the nearby Weber and Provo Rivers.

Like so many species, the native cutthroat trout of Utah are under significant pressure due to drought, habitat loss, disease, and competition with non-native species. Though only the Colorado River cutthroat is included on the Utah State Sensitive species list, conservation of all of Utah’s native cutthroat populations is a focal point for state wildlife resource managers.

I Love the Four Seasons

I love the four seasons. Having spent my 72 years residing in the mid latitudes, I’ve learned to celebrate each of our seasons, but especially spring!

This is the rebirth flush with abundant water, new greenery, and air filled with bird song and sweet aromas as new flowers perfume the air hoping to lure in a pollinator.

With mid-April upon us and our 42 degree latitude, spring is in full swing here in northern Utah! Winter departs grudgingly slapping us with snow squalls intermingled with glorious, early summer days, a wild roller coaster ride which I truly enjoy!
I’m an avid phenology follower. Phenology is the study of how life adapts to seasonal changes. I revel in the first floral bloom, the first neotropical birds returning from Latin America with a heart full of song, and newly emerged, gaudy butterflies.

With a relatively stable climate, until recently, the timing of these events has evolved to near perfection
Let’s take a closer look at some of these phenomena. I’ll begin with our neotropical birds such as lazuli buntings, yellow warblers, and Western tanagers to mention a few. These species spend over half of their year in Mexico, Central and South America flying thousands of miles to for the breeding and nesting season in the Intermountain West. This may seem a bit extreme for these tiny flurries of life.

On closer inspection, you will find they have good reason for this daunting and dangerous task. The tropics have a relatively stable climate without the dramatic seasonal change that we experience. This results in relatively stable populations of flowers and insects, the primary food sources for most species. Further, the ratio of daylight to darkness is nearly constant with 12 hours of each. Our days lengthen as we journey toward summer solstice with nearly 16 hours of daylight! This allows a burst of energy to flow through ecosystems resulting in eruptive populations of insects and floral bloom. It also offers long hours of daylight for parents to gather food for their young which grow rapidly toward fledglings, thus reducing the possibility of predation and also preparing them for the arduous flight south as fall approaches.

Let’s examine flowers and insects. With our very warm winter and spring, I was expecting a much earlier arrival of both and was not disappointed. I counted 17 species of flowers by the second week of April! And butterflies were on a similar schedule with 9 different species during the last week of March- remarkably early! Although delighted, it occurred to me that returning birds may not be so pleased. If the flowers begin to fade, and insects begin their downward slide at the peak of birds rearing their young, trouble is afoot! A five year Audubon study revealed that 1/3 of our birds are predicted to be severely impacted by these rapid climate shifts.

On a more positive note, spring will continue as will bird song, vernal waterfalls, eruptions of wildflowers and butterflies. And spring repeats itself as we move to higher elevations. As cornices on our mountain ridges recede, up pops flowers for yet another spring bloom, and with them butterflies, bees, and birds!

Fitting the Bill: Few among us would choose to eat a steak with a spoon or soup with a fork. And in the world of birds, it’s the same story – you need the right tool for the right job – and you can tell a lot about a bird by paying attention to its beak.

Physiologically, beaks are a specialized extension of the skull and are coated in keratin – the same material that makes up our fingernails. And like our fingernails, the cutting edges of the beak can be re-grown as they are worn down by use.

Birds use beaks for a multitude of tasks including preening, weaving nests, and defending territories. However it is the task of eating that seems to dictate beak shape and size. Envision the hummingbird, for instance. Its long, thin beak – and corresponding tongue – is designed to reach deep into flowers to collect the nectar within. A hummingbird beak would not work for a woodpecker or a great horned owl. Likewise an eagle’s beak needs to be sharp and strong for tearing flesh, and wouldn’t suit the lifestyle of an ibis or a sparrow.

One Utah native, the aptly-named red crossbill, has one of the most unique beaks around. When closed, its curved top and bottom bills overlap crossways in what looks like an awkward and uncomfortable pose.

French naturalist Count Buffon, first laid eyes on a crossbill in the mid-1700’s. The bird was collected in the Americas, then shipped abroad for examination. Without observing the crossbill in its natural habitat, Buffon labeled its beak “an error and defect of nature, and a useless deformity.” More than 50 years later, Scottish-American naturalist Alexander Wilson observed a crossbill in the wild and determined that its beak ‘deformity’ was in reality a magnificently adapted tool. The crossbill’s diet consists mainly of the seeds of conifer trees, and it turns out that the bird’s curiously crossed beak is perfectly adapted to prying apart the scales of pinecones to get at the seeds within.

Members of the finch family, these birds are often seen in flocks and occasionally visit backyard feeders. They are easily identified by their unique beaks, which serve as a reminder that the right tool for the right job can sometimes seem a bit unconventional.
