The Amazing Uintas

Hi, I’m Holly Strand.

Coming from Colorado, I’m something of a mountain snob. So while I always found Utah’s mountains to be agreeable, I admit to thinking they were somewhat petite. Then I saw the Uintas. About 200 miles long and 30-40 miles wide, the Uintas lie south of the Wyoming border primarily in northeastern Utah but with its eastern flank extending into Colorado.

There are several interesting features that make these mountains stand out in my mind.

For one thing, the Uintas are one of very few east-west trending mountain ranges of significant size on the planet. The only other one in N. America is the Brooks Range. This east-westness can feel strange to someone who orients themselves on a north-south axis. Because the path the sun follows the range instead of crossing it, my sense of direction was thrown off. Perhaps this happens to others too and that’s why we often hear about people getting lost in the Uintas.

Glaciation is another interesting aspect. The Uintas were more heavily glaciated than any other part of Utah. The most recent glacial episode was approximately 30,000 to 10,000 years ago. These Pleistocene glaciers left wide-bowl shaped valleys and scooped steep-walled cirques near the main ridge line. Nowadays, sparkling lakes, streams and meadows grace the ice-carved basins and valleys.

Speaking of lakes, even a Minnesotan might be impressed with the density of the Uinta Mountains lakes. Of course, the total number depends upon what you define as a lake. But most sources say there are between 800-1000 heavily concentrated in the High Uintas.

Utahns gets a lot their water from the Uintas. The mountains are an important source for several Wasatch Front rivers and streams including the Bear, the Weber, and the Provo. Precipitation and snowmelt on southern slopes either flow into the Duchesne River or directly into the Green River.

Because they are below 14,000 feet, the Uintas didn’t fit my Colorado-derived definition of “real mountains.” However there are 17 peaks all over 13000 feet–the highest is King’s Peak at 13,528 feet. Considering the beauty and wildness and the water features in these 13ers and their surroundings, the Uintas definitely scored with me. I’m looking forward to returning to explore some more.

Hi, this is Mark Larese-Casanova from the Utah Master Naturalist Program at Utah State University Extension.

When exploring wetlands, streambanks, and the shores of Great Salt Lake this time of year, it’s common to see tall grasses, over ten feet high, blowing in the breeze. While it is very abundant, the common reed known as Phragmites australis is anything but normal.

Phragmites was introduced from Europe over a century ago, and is now found in all 50 states and on every continent except Antarctica. It can grow to more than 15 feet in height, with long blade-like leaves. It flowers from July to October, producing dense, feathery clusters of small flowers that are purple while flowering and turn light brown after producing seeds. Each stem can produce up to 2,000 wind-dispersed seeds that are particularly effective at colonizing new areas. Because of this, Phragmites can take over a disturbed area quickly and prevent native plants, such as bulrush and cattail, from becoming established.

Like other invasive plants, Phragmites is successful at outcompeting native plants. Once a plant is established from seed, Phragmites spreads quickly through rhizomes, or underground stems, that can produce many additional stalks. While Phragmites may start growing among other wetland plants, it quickly outcompetes them for nutrients and sunlight. However, the native “Phragmites australis subspecies americanus” does not grow nearly as dense or tall, and tends to not be invasive.

Because introduced Phragmites can quickly grow into solid stands, it can greatly reduce plant diversity in wetlands, ultimately reducing the quality of wildlife habitat. Wetlands along the shore of Great Salt Lake are particularly important habitat for many migratory birds species, some of which occur here in the largest populations in North America or the world. The rapid takeover by Phragmites in these wetlands could eventually have dramatic impacts to the entire Great Salt Lake ecosystem.

In order to combat this threat, wetland managers have tried several methods for controlling or removing Phragmites, including spraying with herbicide, burning, livestock grazing, and mowing. Dr. Karin Kettenring, a Utah State University researcher, and her graduate students are currently studying the effects of several of these Phragmites control methods along the shores of Great Salt Lake. By experimenting with the timing of mowing and herbicide treatment, as well as covering mowed Phragmites with heavy black plastic, Dr. Kettenring and her team hope to find the most effective combination of treatments. With the continual conversion of native wetland habitats to a monoculture of Phragmites, Dr. Kettenring’s research is of particular importance to maintaining the health of the Great Salt Lake ecosystem- one of our state’s greatest natural wonders.

Beavers: The Original Army Corps of Engineers

Hi, I’m Holly Strand from Stokes Nature Center in beautiful Logan Canyon.

Beavers and beaver dams are a common feature of the Utah landscape. You’ll see the dams on smaller streams and side channels, constructed of branches, downed trees and mud. The still, deep water of the resulting pond creates ideal conditions for a beaver lodge. Beavers can escape and hide from predators by slipping into the pond and disappearing into the lodge. Beavers also use their ponds to cache their favorite
food—aspen and willow.

Because of their tree cutting and dam making skills, humans tend to have two divergent opinions of beavers: 60-pound nuisance or environmental engineer.

Beavers are considered a nuisance when they gnaw down trees that humans want to keep. Dams can flood roads or stop up irrigation canals. When beaver activity conflicts with human interests, they—the beavers–are likely to be trapped and killed.

However, beaver activity has many positive environmental consequences that we are just beginning to appreciate. Wetlands created by beaver dams help soak up sediments, improving downstream water quality. Because of beaver dams, the winter snowpack isn’t lost in a short spring pulse, This results in a more constant stream flow through the summer –and that’s important as Utah’s climate is predicted to become drier. Finally, beaver dams enhance habitat for many other fish and wildlife species and plants.

According to Dr. Joe Wheaton, a geomorphologist at Utah State University, there’s a lot of untapped potential for employing beaver engineers in stream and floodplain restoration. Say you want to restore a stream by reconnecting it with its floodplain. You need to excavate channels, redirect stream flow, revegetate and nurture the
area for a long period of time. To accomplish this, you often need a
number of highly trained professionals and some large Tonka toys.

Alternatively –under the right conditions– you might transplant a
colony of beavers and let them apply their vigorous work ethic to your
landscape and get quite satisfying results.

Recognizing that nuisance beavers can be rehabilitated into hard
working wetland engineers and stream habitat restorationists, the Utah
Division of Wildlife Resources has rolled out the state’s first beaver
management plan in 2010. This plan encourages live trapping of entire
families of beavers in nuisance areas and moves them to specific sites where their
environmental services can be appreciated and put to use.

Wetlands-What’s in a name?

Wetlands- What’s in a name?

Hi, this is Mark Larese-Casanova from the Utah Master Naturalist Program at Utah State University Extension.Wetlands- What’s in a name?

A wetland really is more than just ‘land that is wet’. There are certain key ingredients that need to go into a wetland for it to truly be a wetland. Of course, water needs to be present for at least part of the growing season. It can simply be in the form of temporarily saturated soils or even standing water a few feet deep.

As soil becomes saturated with water, oxygen levels are greatly reduced. Quite often, bacteria in saturated soils will create hydrogen sulfide, giving wetland soils that stinky odor of rotten eggs. As plants grow in a wetland over several years, their decaying matter helps to create a thick, dark layer of organic soil.

The presence of water in a wetland encourages the growth of hydrophytes, or ‘water-loving’ plants, that are specially adapted to living in wet environments. Many wetland plants have open spaces within the leaves and stems- often referred to as aerenchyma. This allows oxygen to diffuse down to the roots, sometimes creating an oxygen-rich environment in the soil around a plant. Also, many wetland plants reproduce both by floating or wind-dispersed seeds and by rhizomes, which are underground roots that can travel great distances. Some plants that grow in salty wetlands around the Great Salt Lake are able to control the salt in their tissues by depositing it on the outside of the leaf or containing it in chambers within their cells.

Like plants, specially adapted animals also call wetlands their home. Mammals and birds have oily fur or feathers that allow them to swim in cold water without losing much body heat. They also often have webbed feet to aid in swimming. Other animals, such as fish, amphibians, and insects, have gills to breathe in water.

Despite being the second driest state in the country, Utah has a high diversity of wetlands. Vast marshes surround the Great Salt Lake, providing habitat to enormous populations of migratory birds. Less obvious wet meadows provide unique habitat to butterflies and other insects. Salty playas, which are shallow basins with no outlet, are found throughout the West Desert, creating unique ecosystems of highly adapted plants. Riparian wetlands can grow along the edges of rivers, providing a unique transition between the swift water and upland habitats. Southern Utah is home to some peculiar wetlands such as potholes and hanging gardens, both associated with sandstone bedrock. A hanging garden clings to the side of a moist cliff, creating a microhabitat for rare plants, such as orchids and monkeyflower. Potholes can simply be eroded basins in the sandstone where water collects in spring. A pothole is an oasis that provides water for desert wildlife and a home for fairy shrimp and spadefoot toads.

Spring is the perfect time of year to visit a wetland. The constant chorus of birds, insects and amphibians are a testament to the importance of wetlands, teeming with life in the middle of a desert.
