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.

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.
