Have you heard about the Yellowstone to Unita Connection or the Western Wildway Priority Wildlife Corridor and the Bear River Range Corridor? What we will talk about today is the critical importance of protecting, maintaining and creating wildlife corridors throughout Utah and the west.

Animals and yes plants and all other critters that live in ecosystems, such as birds, insects and amphibians, always suffer when their ecosystem and the ecosystems that are adjoining theirs, either through land or water corridors are fragmented and minimalized, if not lost altogether due to human activities. The ever expanding web of roads and highways, residential and commercial development, intensive agriculture, energy development and off-road vehicle trails in essence trap animals in an ever shrinking island of non-connected ecosystems. Its when species can’t move between ecosystems to mate, migrate, eat, pollinate, find new homes and resources. recycle nutrients, take refuge and more, that inbreeding can cause significant problems for flora and fauna. Sometimes even extinction.

Our politicians and agency folks, as well as developers, farmers and ranchers, businesses and everyday residents can all help to assure that we preserve, maintain and develop a network of these corridors connecting large and small ecosystems running from Canada, through the United States into Mexico.

One such large project, called the Spine of the Continent, is a geographic, social and scientific effort to sustain linkages, along the Rocky Mountains, so that plants and animals can keep moving. A local example, the Bear River mountains, located in northern Utah and southern Idaho, is a relatively narrow tract of forest land in the Uninta-Wasatch-Cache National Forest and the Caribou and Targhee National Forests. This mountain range and surrounding basin are a key component of the western United States biological corridor system. The Bear River basin corridor is a critical choke point for species migration in the western United States because it offers the only major link between the northern and the southern Rockies. Or more specifically, the link between the greater Yellowstone ecosystem and the high Unitas wilderness area.

Here’s how you can get involved:
We have dedicated organizations working on the protection, expansion and maintenance of wildlife corridors. I mentioned the Yellowstone to Unita connections. They along with the Bear River Watershed Council and others in our state are actively working on wildlife corridors. I spoke to Dr. John Carter, manager of the Yellowstone to Unitas connection about their program. They are doing great work to restore fish and wildlife habitat in the Yellowstone to Unitas corridor, through the application of science, education and advocacy. He invites you to check out their website at www.yellowstoneuintas.org.

Wilderness 16 Feb 2015

Wilderness. The word conjures up romantic images of wide open landscapes teeming with birds, beasts, and plants. I imagine places untouched by human influence – truly wild and free. Places that are exotic and far away.

But wilderness exists much closer than you may think.

The United States Congress adopted the Wilderness Act with a nearly unanimous vote in 1964. Ours was the first country in the world to define and designate wilderness areas – lands valued enough to be set aside for the purpose of protection.

Currently, the Wilderness Act protects 757 individual wilderness areas across the United States – totaling more than 109 million acres. Thirty-three wilderness areas are found in Utah, and they protect a variety of unique landscapes from the red rock desert found in Red Butte Wilderness to the alpine forests of the High Uintas Wilderness. While the landscapes may look incredibly different from one wilderness area to the next, these lands share a number of qualities which can be described by adjectives such as peaceful, quiet, untouched, and pristine.

These areas protect some of the most unique and incredible landscapes that Utah has to offer, but that doesn’t mean they’re off limits. Our wilderness areas are just that – ours. They are public lands, accessible to anyone who wants to visit – so long as you tread lightly.

Areas that fall under its protection are described in the Wilderness Act as “lands designated for preservation and protection in their natural condition…” which “…shall be devoted to the public purposes of recreation, scenic, scientific, educational, conservation and historic use.” These amazing lands were set aside in 1964 with an eye to the future and because of it, should still be around for your grandchildren’s grandchildren to enjoy.

There is an ongoing effort to educate Americans about the immense value of preserving wilderness areas. For without education, they may one day be selfishly reclaimed and lost. One of these educational opportunities is coming to Logan on April 13th and 14th. The Arthur Carhart National Wilderness Training Center will be hosting a teacher training workshop in conjunction with the Stokes Nature Center and the Utah Society for Environmental Education. The workshop is aimed at teachers in grades 5-8, though anyone is welcome to attend. For more information, please contact the Stokes Nature Center at www.logannature.org

Not a teacher? The best way to learn about wilderness areas is to go visit one! Information, and photos of Utah Wilderness Areas, can be found at www.wildaboututah.org

Riparian Zones and a Critter Quiz

Hello, this is Jim Goodwin.

In a minute I’ve got a critter quiz for you, but first, a word about the huge importance of riparian areas in semi-arid Utah, the second driest state in the union. Utah State’s Extension Service calls riparian zones the green ribbon of life alongside a stream. They are shadier, cooler and moister than adjacent environments.

And with a diverse mix of plants and animals, our few riparian corridors are heavily used by wildlife for food, rest and shelter.

Ok, now for our critter quiz.

What is the largest rodent in North America? Here’s a hint: they can be up to four feet long and weigh 40 to 60 pounds.

Did that do it? No? Alright, this clue will: They spend much of their life in water. They have a beautiful brown coat, a broad flat hairless tail and big orange buck teeth that continually grow, which is why they chew and chew and chew.

Good, you got it . . . it’s the North American beaver. Or as Utah environmental author Chip Ward calls them: the Flat Tail Climate Hero for the restoration of damaged watersheds. Beaver are amazing aquatic engineers, second only to humans in their ability to manipulate their environment.

In our nation’s history, they’ve played a big role in literarily shaping our western landscape.
Joe Wheaton, Utah State wildlife and a beaver expert, rightly calls the work of the beaver “cheap and cheerful restoration” of our heat stressed watersheds.

In the wild, these mostly nocturnal animals, normally live five to ten years.
Fortunately, they are rarely killed for their pelts these days. Beaver are usually monogamous. They will produce up to 10 babies. The young kits will stay home until they are two or so, before they will take off on their own.

Beaver are master aquatic builders. the original geo-engineers. They build dams to flood areas for protection from predators, for access to their food supply, and to provide safe underwater entrances to their dens. Their dams create beautiful riparian habitat for many other animals, birds, fish amphibians, insects and plants. The flooded areas slow the flow of water and sediment downstream and raise the area water table.

Aspen, cottonwood, willow and dogwood are their preferred tree. Those trees regenerate quickly after beaver topple them. When their ponds freeze over, beaver jam smaller branches into the mud at the bottom of their pond for food storage.

Beaver dams can be 5 to 10 feet high and 150 feet across. They are constructed with branches, stones, and plants and plastered together with mud. Over 1200 beaver dams have been counted in northern Utah’s Bear River mountains alone. The World’s largest beaver dam in Canada is 2,789 feet in length. That’s more than 9 football fields.

Yes, sometimes beaver can be a nuisance to human property and activities. Often, learning to live with beaver and the many benefits they can bring, can be a solution. There are simple time-tested ways to prevent flooding. But if nothing works, they can be live trapped and moved to another area. There’s no need to shoot them.

Be a “beaver believer.” Here are some organizations you can check with to learn more:
Utah State wildlife researchers Wally McFarland and Joe Wheaton have created something called the Beaver Restoration Assessment Tool to track beaver dam building activities and their effects throughout the state.
The Bear River Watershed Council in Cache Valley and Mary O’Brien with the Grand Canyon Trust in southern Utah are excellent organizations to contact.

Shrimp in the desert landscape of Canyonlands National Park? Yep. You can find them, –fairy shrimp– when the rainy season arrives and turns dry, dusty potholes into water-filled rock basins brimming with life.

A surprising array of creatures relies on these potholes for life, and one of the most curious is the fairy shrimp. These unique crustaceans are found in small potholes that dot sandstone outcrops found in America’s Southwest. Their eggs maintain resilience during the dry season, and when spring rains arrive, the shrimp hatch.

There are more than 300 varieties of fairy shrimp, the most common being the Vernal Pool Fairy Shrimp. These little guys measure between a half-inch to one-and-a-half inches long as adults. They can be found anywhere ephemeral pools are present, though the majority of their population resides in California and Oregon.

Fairy shrimp vary in color depending on the menu found in their particular pool of residency, ranging from translucent, to orange, even to blue! They feature 11 pairs of legs to propel themselves upside-down, or more scientifically, ventral side-up.

They also use these incredibly helpful legs to eat unicellular algae, ciliates (sil-ee-its), and bacteria by filter and suspension feeding methods. They filter-feed by pumping water through filtration structures — located in their multi-purpose legs — thus capturing the food. They also are adept at suspension feeding by plucking food floating in the water, again, with their tentacle-like legs. They may also grab or scrape food from the surfaces of other things in their vernal pool, such as sticks and rocks.

What’s truly amazing is how fairy shrimp reproduce. They typically lay drought-tolerant eggs during the summer that over-winter in the dried sediment on the pot hole bottom and then hatch in the spring when the potholes fill with rainwater However, if drought sets in, eggs can be transferred to other pools by floating in gusts of wind or being carried by a particularly curious animal.

These eggs are tough and can withstand varying temperatures, drought, and even the test of time; eggs in laboratory settings have survived intact up to 15 years before hatching.

Under the right conditions, you can observe fairy shrimp in Canyonlands, Arches, and Death Valley national parks. Canyonlands and Arches boast at least two species of fairy shrimp: the Packard Ferry Shrimp, also known as the Rock Pool Ferry Shrimp or the Arizona Ferry Shrimp, and the Great Plains Ferry Shrimp.

Fairy shrimp hatch in the Spring, right after the potholes and vernal pools re-fill with water, so that will be your prime time to look for these interesting creatures. As travelers, you can do your part to help the fairy shrimp by leaving their vernal pools alone. Drinking water, stepping in, or touching a pool can throw off the entire mini-eco-system located in this fascinating habitat.

And remember, our fingers are very salty, so even if you’re using a gentle touch, do not put your fingers in a vernal pool, as it just might raise the salinity and throw off the dissolved oxygen percentage needed for fairy shrimp to survive.
