I’m a beaver believer. These remarkable rodents are a critical part of the ecosystem, a keystone species. The beaver’s role in creating wildlife and fisheries habitat, filtering and cooling water, and adding new water storage capacity, is essential for our prolonged drought in a warming climate.
When I had a neighbor call a few weeks ago to report he thought a beaver might be cutting down his aspen trees. I was in disbelief. Right here in our little city of Smithfield no less! John invited me over to confirm his suspicions.

After inspecting the tree stumps, teeth marks were undoubtedly those of beaver. We discussed on how to address the situation. John had lost several thousand dollars-worth of trees, and was quite desperate to remediate the situation. I suggested reporting the rogue beaver to animal control or UDWR. Perhaps they could live trap and transport the animal to a more favorable location, while dreading the possibility of having to destroy my iconic, heroic mammal friend. In the interim, I suggested he use chicken wire to save what remained. Another personal conflict arose from my position as Smithfield Tree Committee chair. I was fully aware of the many values urban forests offer to our local environment and quality of life. It was my mission to protect our trees.

I inquired as to where the beaver was setting up shop. There must be a tangle of aspen leavings nearby. John hadn’t noticed any. I began searching the stream to find the missing trees, never expecting to see a beaver. Not more than 20 yards upstream from his property boundary, there it was. I quickly took a picture before it slid into the water disappearing beneath the ice.

I returned to my neighbor who was busy installing chicken wire around his remaining aspen. He too was not wishing to exterminate the animal, but there were homes with aspen, willow, and cottonwood both up and downstream from our location, a veritable feast for this wanderer. I mentioned that I had some acquaintances at USU who worked with beaver reintroduction, and may offer some solutions as well.

Given its small size and unexpected location, this was most likely a two-year-old juvenile who had been forced from its family, similar to how we gently nudge our young adults out the door. I was well acquainted with our mountain landscape and quite certain this beaver had traveled a distance of many miles to end up in Smithfield.

After consulting my USU friends, it did not bode well for poor beaver. To catch and release this animal during the winter offered little hope for its survival. Further, it would not fare well in several months of captivity, being alone in a high stress environment.

I’m now waiting to hear from my neighbor for the rest of the story. May it be favorable for this remarkable aquatic mammal, so essential for creating healthy watersheds, which equals abundant, high quality water!

When Jay Wilde graduated from Preston High School in 1963, he took off to see the world. Thirty years later he came back, bought out his siblings, and moved into the family homestead in the hills above Preston, Idaho. He had acres of pasture and two hundred mother cows. But one thing was missing. Water. Birch Creek, which had run year round when he was growing up, now dried up in June. Hiking up to the headwaters, past his deeded property and into the National Forest, Jay found something else was missing. There was no sign of the beavers he remembered seeing there in his childhood. Now there were no beaver dams to slow down the flow of melting snow, and rainfall, spread it out into tiny reservoirs, and most importantly, no way to allow the surface runoff to filter down into the ground water.

On his own dime, Jay got some beavers and released them in the mountain headwaters of Birch Creek. Nothing happened. A year passed. The beavers were gone.

But help was on the way.

Enter Joe Wheaton, a beaver specialist at Utah State University. Joe bought a truckload of poles and recruited some student volunteers. Up the canyon they went, pounding poles into the streambed and weaving a few branches between the poles. Hopefully these structures would become “kick starter dams” for the next try at releasing beavers.

In 2015 five beavers were released. The beavers took one look at the kick starter dams and decided these dams suited them fine. They moved in and went to work.

After a few years, Jay and Joe checked the beaver’s progress. They found a thriving beaver community, and counted over 12 dams. The beavers seemed to be marching to Joe’s mantra for controlling spring runoff: “Slow it. Spread it. Stow it.”

And now, for the latest update to this story.

Earlier this month I was allowed to tag along with Jay and Joe and two others as they tramped up to the headwaters of Birch Creek. We found a watery paradise. Melting snow was trickling over and around the dams, cascading down into deep pools, and spreading out into lush green meadows. There were too many dams to count, but Joe said over 200. Jay smiled and said down below Birch Creek was running 40 more days.

And I – I just burst into song!

Finding a beaver dam gives me a sense of discovery and connects me to the past. I fondly remember my parents pointing out dams when we drove up Logan canyon. Instinctively, we’d scan, hoping to see the animals that built and maintained those structures. When we talked about beaver dams, the conversation often turned to trappers who would rendezvous and re-supply in the Bear Lake and Cache valleys. We lived where history had happened, and I was eager to know more.

Years later, inspired by a history class, I read Dale Morgan’s Jedediah Smith and the Opening of the West. Morgan followed the travels of Smith and his fellow trappers who answered William Ashley’s 1822 ad in the Missouri Gazette requesting “ONE HUNDRED MEN, to ascend the river Missouri to its source, there to be employed for one, two, or three years….”

Ashley’s troop competed with the Hudson’s Bay Company, the American Fur Company and several native indigenous tribes, all trapping beaver. The story sounds familiar: beaver pelts, and later bird feathers, were used to create hats, and the movement to harvest them led to a significant decline in numbers. For the birds, this decline led to building refuges and other conservation efforts. But the plight of the beaver continued downhill as exploration and discovery encouraged an influx of settlers. For the next century, the remaining beaver were regarded by those settlers as invasive land-grabbers, in competition with efforts to direct water, mine and irrigate.

However, today beavers are gaining more respect as we better understand the benefits of their skills in supporting wildlife and wetland conservation. Researchers at Utah State University, including Joe Wheaton and Nick Bouwes of the Department of Watershed Sciences, are studying habitat improvement after beaver introduction as a cost-effective way to combat drought and fire.

They have repeatedly demonstrated, over the past few years, that beaver families can be introduced and thrive behind fabricated beaver dam analogues(BDAs). After release into the resulting ponds, the beavers take over maintenance and produce their own dams. Over time, these dams and their rodent engineers improve stream flows, raise water tables, and cool water temperatures.

In essence, active beaver dams create Mesic habitats where the land maintains a well-balanced supply of moisture throughout the growing season. These dams slow spring run-off as they retain water in ponds and the surrounding soil, thereby, securing water for fish, trees, birds and wildlife. The best part is that the beavers do the maintenance.

When wildfires occur, beaver oases preserve wildlife and habitat. However, if beaver and their habitats don’t exist in an area before a fire, they can still play a role. By retaining water with beaver dam analogs, we can create wetlands conducive to beaver habitat. In Joe Wheaton’s words, “We can’t dump beaver into a watershed that has burnt to the ground and expect them to do the restoration of degraded streams on their own…. What we can do post-fire is accelerate recovery with low-tech structures that make it easier to more quickly get beaver into an area and accelerate recovery. We’d like to help them do that.” (Utah State Magazine, Winter 2019, p.12)

The Price and San Rafael rivers flow through some of Utah’s driest areas. Both are tributaries of the Green River. These rivers are essential to sustain the wildlife, riparian vegetation, native and endangered fish populations, and livestock that live in Utah’s eastern desert.

Beavers, native to both rivers, have far-reaching impacts on these waterways because of their ability to build dams which hold the water on the arid landscape – they are nature’s aquatic engineers.

One beaver dam can improve the living conditions for a host of fish, insects, plants, birds and mammals who live in and around the river.

Emma Doden, a graduate student in the Department of Wildland Resources in the Quinney College of Natural Resources at USU is working to understand the dynamics of beavers who are translocated to desert rivers for restoration purposes and how they compare to the naturally-occurring resident beavers who are already established.

Doden explains, “I help relocate nuisance beavers to desert river systems to give them a second chance, and help restore the river for the imperiled and endangered fish species…in this arid climate.”

Currently, Doden’s work is “passive desert river restoration” because there is no machinery manipulating the landscape or man-made structures impacting the research results. She is relying solely on beavers and their resources which have been part of the rivers’ ecosystems for millions of years. The beavers’ engineering teeth, tails, and paws build dams and lodges from riparian vegetation, gravel and mud.

Many of the translocated beavers come from the USU Beaver Rehabilitation and Relocation Center which captures nuisance beavers, quarantines them for three days to ensure they cannot spread disease, then passes them to Doden to be released in the desert system.

Nate Norman, a field biologist in the USU Ecology Center who helps operate the Beaver Rehabilitation and Relocation Center said, “Working with Paul Chase from the US Forest Service we have trapped and relocated approximately 8 to 10 beavers from around Cache Valley [in northern Utah, to the desert rivers in Doden’s research.“

Both the resident and translocated beavers in the study receive a radio-transmitter and PIT-tag in their tail.

Doden explains, “The PIT-tag is similar to the microchip [a] dog or cat gets at the vet for identification if it ever gets lost. We use radio-transmitters and PIT-tags to track the movements of our beavers so they do not become lost after release.”

To this point, 90% of the translocated beavers have moved outside Doden’s research area as they explored their new habitat. They were probably searching for a companion and a suitable place to build a home.

This travelling increases the beaver’s vulnerability to predators since they have no underground burrow or lodge for protection. During the 2019 field season, of the eight beavers released, three of the translocated beavers were taken by predators.

Many of the tributaries of the Green and Colorado rivers are wood-deprived because of changes in the river flow due to human extraction. To increase a translocated beaver’s chances of surviving and its likelihood of remaining where it’s placed, the research team has proposed building simple dam-like structures out of wood fence posts, which would encourage the beavers to stay where they’re released. Once they receive NEPA approval the structures will be built.

Doden adds, “Our project goals are already being met, as we are learning so much about the fate of translocated beavers in desert ecosystems. Restoration goals will also be met if even a few beavers stay in the study area and build dams, supplementing the resident beaver population and creating more complex habitat for imperiled desert fish to live.”
