Leave it to Beaver

A few years ago the Utah Division of Wildlife Resources conducted a wonderful workshop for educators to provide them with materials to take to their classes to help students understand the many issues dealing with wildlife.

As an introductory activity, the Ranger asked each of us to name the animal we thought that had the greatest influence or impact on ecosystems. People mentioned Deer, Cougars, Moose, Wolves and so on until it was my turn. Without hesitation I said “Beavers”. One of the teachers laughed at me and mocked my answer trying to embarrass me. So I asked the Ranger to repeat the question: Which animal did we think had the greatest influence or impact on ecosystems.

“Oh”, I said making certain I had now understood the question. “In that case I have no hesitation now in saying the Beaver.” The room grew quiet, but the Ranger agreed with my answer.

There is no question that all animals impact ecosystems. Heavy grazing or browsing by deer or elk can change the structure of forests and meadows. Predators, or the lack of them, can definitely alter what happens to those species. But consider the beaver for a moment. There are positive and negative things they do, but they definitely impact ecosystems. So consider this love-hate relationship humans have with them.

Yes, they will take down some trees to build dams and lodges. Problems might include:
The potential flooding of homes, agricultural land, timber land or orchards;
Their abandoned dams can create floods as they collapse;
There is potential flooding of roads and blocking of culverts;
And the deterioration of stream banks can occur.

But in a natural setting, where they do not impact roads or developments, beavers can do amazing things.
On the positive side, they create ponds which:
Provide habitat for trout;
Provide drinking water for all the animals in the area, from birds to bears;
Provide a storage of water that could be critical in drought conditions;
Trap silt and control small floods;
Invigorate the sprouting of early riparian and wetland plants;
Can help combat the effects of continual rising temperatures and earlier Spring snowmelt by maintaining a water supply for ranching, wildlife and native vegetation;
And they are basically constructed and maintained at little or no cost to humans.

Utah State University, and the Division of Wildlife Resources, have been developing partnerships with landowners to help restore beavers in locations where they can succeed and provide benefits to the land, wildlife, and ranching efforts. In areas where there are few trees, they construct Beaver Dam Analogues by pounding fence posts across streams, weaving willow branches between them, and plugging the base with large rocks and mud. These are similar to natural beaver dams and give them a good start to build their own homes there.
If you are aware of any beavers in questionable areas, contact

USU Watershed Sciences or the DWR to help relocate them where they can impact ecosystems in positive ways.

Riparian Zones

Summer’s heat has turned on. It was evident in a dramatic fashion as I ran a ridge in N. Utah where the early am temps were near 70 degrees, flowers had faded, and the absence of bird song. As I descended to the canyon bottom the temperature dropped a solid 20 degrees and bird voices returned where yellow warblers were competing with lazuli buntings for top songster. I had entered the riparian, or river side biotic community- from the burnt brown of cheat grass above to the lush “green zone” below supporting abundant life in our desert state. I won’t be running ridge tops any time soon!

Throughout the Intermountain West and Great Basin, these givers of life are critical areas for water, wildlife, agriculture, and recreation. About 80 % of all animal life is dependent on stream side habit sometime during its life cycle. As a birder and botanist, this is where I spend much of my time documenting and enjoying the abundance.
On a recent, brief bird survey along the Logan River golf course trail, I recorded 33 species with another ten or so known to nest in this river corridor. I’m planning to prepare a bird checklist for golfers to add more “birdies” to their score card.

Many of these special places have been seriously degraded through invasion of exotic species, agricultural practices, various forms of development, and channelization. But help is on the way.

The Logan River Task Force is one excellent example. Launched in 2016, the task force is well on its way to restoring a much healthier, biologically rich river system. Replacing crack willow, a Eurasian non-native tree, with native cottonwood and willow accompanied by a rich understory of shrubs, will significantly enhance the biodiversity along the floodplain. Another major change is underway as they replace the straight, channelized portion of the river to its meandering original channel. This will create more pools for fish, wetlands for flood control and filtering, while improving aesthetics and recreation opportunity.

In an earlier WAU reading, I mentioned the good work being done by western boxelder ranchers reintroducing beaver whose dams will assist with maintaining stream flow and water quality along with improved fish and wildlife habitat. I’m aware of the same occurring on a Mink Creek ranch in SE Idaho.

The world appears to be awakening to the many values of these critical wildlife and water quality riparian zones, as I awoke to the same on my early morning run.

The Bear River

Following the same route which I had taken when coming up, we arrived at Bear River on the evening of the eleventh and encamped. Examination of Cache valley occupied several days. Crossing over the range of low rounded hills through, which Bear River has cut a passage, we entered this beautiful and picturesque valley. Which was then covered with a profusion of rich green grass and adorned and diversified by numerous clumps of willows. The valley is full of swampy springs affording an abundance of good sweet water and excellent grass. Speckled trout, large size, abound in the streams. I believe this passage to be from “Journal of a Trapper” written by mountain man Osborn Russell around 1816.

The Bear is a unique and beautiful rivering system. Superlatives abound. A river of profound beauty, who provides over 60% of the life blood for the Great Salt Lake eco system. The largest river, to begin and end in the Great Basin. A river which witnessed the largest massacre of Native Americans in our country’s history. A river of abundant life, who supports three national wildlife refuges, in its 500 mile course.

There were a few thoughts running through my brain as I canoed down a stretch of the Bear River though Gentile valley, in southeast Idaho this morning, counting bird species for Utah Power and Light. I was stunned by the beauty as we left the bank, into early morning sunrise, in a river mist with rain clouds forming over surrounding mountains. Our spirits were further buoyed by rampant bird songs, Canada Geese, Sandhill Cranes, Meadow Larks, Red Winged Blackbirds countless swallows and songbirds. Occasionally sun would find a hole in the clouds and awaken the hills to vibrant Spring green offset by dark clouds gathering.

A large white bird appears on the water ahead of us. Perhaps another pelican. Drifting closer we startled this elegant graceful being, which emits a loud trumpeting call to echo through the shrouds of fog. Trumpeter Swan. We are held in awe of this magnificence. Still on the endangered species list, due to overharvesting and habitat loss.

Winding our way through many river miles we finally arrived at the backwaters of Oneida Reservoir, as the river disappears in a rugged defile called the Narrows. Most of this once magnificent stretch of wildriver now lies beneath the reservoir

Sixty In-stream Habitat Structures in Four Days: Demonstrating Creek Restoration Techniques

The job of building 60 in-stream habitat structures in one week seems like a daunting task. But an energetic group of 16 natural resource managers, researchers and volunteers, finish all 60 in four days.

The crew members come from numerous agencies including the Bureau of Land Management, Utah Division of Wildlife Resources, the National Forest Service, interagency firefighting hotshots, and Utah State University.
The purpose of the project is to demonstrate how effective various in-stream structures are at improving habitat for Bonneville cutthroat trout and restoring riparian habitat on a two-mile stretch of Utah’s Birch Creek, located southeast of Beaver, Utah.

At one time Birch Creek was rich with beaver, riparian vegetation and diverse in-stream habitat making it an ideal home for Bonneville Cutthroat trout and sage grouse.

The beaver are now gone, and the once woody riparian vegetation has been largely replaced by an encroaching pinyon-juniper forest. The creek is one narrow ditch-like channel.

According to Joseph Wheaton, Associate Professor in the Department of Watershed Sciences and Principal Investigator, “Without the help [of man-made structures or beaver dams] recovery from this type of degradation could take centuries.”

The crews built a variety of simple structures, some designed to mimic beaver dams and others to imitate natural accumulations of wood and debris jams.

The largest structures are built with an excavator. The machine pulls up large junipers and drops them in the stream so the water can run over, around and through the juniper and its root wads.
Wheaton explains, ”By putting the [Juniper} in the channel we’re making habitat for fish and at the same time raising water tables, which support a whole range of riparian vegetation and wetland vegetation.”
Another structure is the Beaver Dam Analogues (BDAs), which is a simple, cost-effective method of using posts and juniper branches then adding rocks and mud to partially plug up the deliberately leaky dams, designed to be passable to fish.

Crews see immediate improvements after each structure is built. New pools form, old-channels that haven’t seen water for decades begin to flow parallel to the main channel, and formerly dry floodplains become wet sponges and wetlands.

These wet sponges will release their water later in the season providing additional moisture in dryer times.
Justin Jimenez, Fisheries Riparian Program Manager with Bureau of Land Management explains why these pools are essential, “We’re working to improve the habitat for native fish by increasing the pool frequency and depth. The depth provides thermal cover.” Which is cooler for summer rearing habitat, and warmer for winter survival.
Before this project began, downstream water-rights holders were concerned about how these structures would impact water for irrigation.

In response to their concerns, Gary O’Brien, a Geomorphologist in the Fluvial Habitat Center at USU installed a common measuring device called a V-notch weir at the top and bottom the of the two-mile stretch to measure the discharge of the stream.

According to O’Brien, “once all the structures fill their pools and the system adjusts for infiltration, we expect the top and the bottom weirs to measure a relatively consistent discharge.”
By the addition of a pressure transducer in the pool behind the weirs, O’Brien will have continuous flow of data at every stage.

With these readings the ranchers can be kept up-to-date on the impact the structures are having on the water resources. The agencies have agreed to remove the structures if gaging shows the structures are negatively impacting downstream water users.

Throughout the project, UDWR, BLM and the USFS will be monitoring cutthroat trout response, and USU will be monitoring how the habitat responds and changes through time.

By monitoring the responses, managers and researchers will be able to make more informed decisions about which types and mix of structures can be most effectively used to restore similar streams cheaply across the state.
