Tenacious Beaver

The most important lessons I can give my daughter are not through me, but instead those found best in the wild. Though she can’t talk, I know she still listens. Though her childhood amnesia is inevitable, I know that neural circuits are still being formed. Those circuits will do her good one day.

Our favorite lesson is in the tenacity of beavers.

This winter, we took one of our favorite hikes through knee-deep postholing snow to one of our favorite beaver dams. The dogs trot ahead, sniff snuffing at the path, darting to the stream that runs alongside our trail and back, and lead us as they have many times before up the trail. When we come to the great beaver dam, one that assuredly took not just years but generations of beavers to build, we stop for a snack and water, and let our daughter sit quizzically in the springtime slush. I explain to her the parts of the beaver’s home: the dam, the lodge, how they store their food. She listens while she smushes snow in her mittens, neural circuits are formed, and we pack up to start the slushy walk back to the car. A good day’s hike and lesson. A Greek proverb is dusted off in my mind, that a society grows great when old men plant trees under whose shade they know they shall never sit. Those beavers are good Greeks, but likely poor hoplites.

Later that spring, we return to the dam, our trail shortened by melted snow. Snow is gone from the trail, but still holding fast in the mountains above. The travel is easier, muddier, but the beaver Platonic Republic justly endures. I explain the parts of the Castorian city-state yet again, and explain what the beavers are doing now as we see fresh aspen fells. They’re collecting good sugars and preparing for their kits. Kallipolis endures, as it has, another year out of dozens of millennia, and even without a cud of pulp in sight. I wonder if beavers have oral traditions?

Time then passes as we all pass through space, and summer buds, blooms, and begins to fade. The cattle have come, grazed, trammeled, and been driven off yet again. We return to Xanadu in the early morning before the sun beats hard. We can get even closer to the dam now that the Forest gates are open, and we prepare for our adventure. My daughter looks around excitedly and drinks water from her cup. The dogs look around excitedly at all the leftover cow pies to investigate. Luckily they’ve dried.

We exit the car and make our short way to the beavers only to discover that tragedy has struck between spring and now. The dam has burst. Like the River Isen, a great work of nature has blown a hole in the waterkeep, and drained the promised pond. The shoreline has receded like a tonsure, the lodge’s secret doors exposed as if by moonlit ithildin, and the water flowing with Newtonian determination towards Great Salt Lake.

It’s shocking at first, seeing this anchor of time heaved asunder, the work of generations of beavers up and smote by spring runoff. All that labor. All those lives well-lived. Perhaps not wasted, but at least now remembered with a sigh. I sigh out as well, and explain this all to my daughter. She listens, pulls on cow-mown grasses, synapses fire, and circuits connect. We complete our hike and eventually go home.

Finally, early this fall we set off for the utopia-that-was once more. Colors have begun to change to golds and crimson. The air is more crisp; the heat more bearable. We saddle up in the toddler backpack, and see what there is to see of the beavers. We arrive to the wonders of hope and joy, and the tenacity of beavers.

The dam it appears is not abandoned. The labor of generations is honored with the restoration of the work. Not in its entirety mind you, for that will again take years and perhaps generations, but the work is underway regardless. Greek thinking again prevails. Whether by purpose or itch it matters not, but slowly the pond is regrowing. The shoreline has risen to swallow back and douse bare earth, and the water is a bit more wine-dark. I excitedly show my daughter, who excitedly is playing with my hat, the work that has happened, and the work yet to do. The beavers will not quit when allowed to do so. They are tenacious little buggers whose teeth grow forever. We take it all in and continue our hike, and eventually go back home. A new proverb pops into my head. A society grows great when we get to work and, figuratively, give a dam.

I sit on the front swivel seat of a drift boat gliding across the smooth water of Newton Reservoir. The sun begins to send morning rays of brilliance over the Cache Mountains. My only child, a 14-month-old boy named James, excitedly wriggles in my lap. Behind me in the captain’s seat is my long-time buddy, Jack McLaren. Jack and I met in graduate school where he was working on a doctorate in watershed sciences and fish ecology. Jack and I have been friends ever since, and any day fishing with Jack is one I cherish.

Jack tells me the Largemouth Bass are on the other end of the reservoir, in the shallow, weedy water where they feast on any living creature they can find, primarily small Bluegill who nest in that area. Using two oars, Jack begins paddling the boat across the reservoir. James’ eyes are mesmerized by the turbulent water eddies that form around the oars with each stroke, and I peacefully observe the world and wings around me. Western Kingbirds, with their gentle yellow bellies and grey head, play chase games as they dive and duck from one cottonwood tree to another on the water’s edge; Bank Swallows make clicking and clacking noises like pulsing electrical wires from the steep muddy embankment where a healthy colony has formed; and Wilson’s Phalaropes do a mating display where the modestly colored male hovers in the air over the brightly colored female, bobbing up and down for nearly 5 seconds, before gently landing next to her.

We reach the far end of the reservoir and begin fishing. Jack pulls a plastic green frog across the top of the water; I bounce a long, brown rubber worm with a neon tail under the water; and James, well, he grabs each bag of rubber worms from the tackle box and throws them over the side of the boat.

Just as I finally distract James with a Banana, “THWAPPP!!” a splash sounds and a commotion in the water catches my attention. A hungry bass thought frogs were on the menu and was fooled by Jack’s lure. He reels in the bass and James and I look at the beautiful, greenish/yellowish creature with the distinguishable black stripe down the side. James, with a mischievous smile, courageously reaches out his pointer finger and gently runs it along the slimy, scaly body of the fish.

We continue to fish and just take in the beautiful morning when the thought strikes me.

“This little 14-month-old is going to be my new, best buddy for the rest of my life. Observing, respecting, being aware of, and appreciating nature has always been important to me. How do I pass this same kind of love and respect for nature onto my own son, the next generation, as my father and mother did to me?”

To that, I don’t have an answer, but maybe, just maybe, James being mesmerized by the flow of swirling water eddies around oar paddles or him using his delicate finger to bravely stroke the side of a slimy fish may be just the right start.

A Tropical Flash in the Desert

Not long ago, while walking up a gravel road in Bears Ears National Monument, my eye was distracted by a flash of brilliant, almost neon green against the red rocks and sand. Soon I got another glimpse, just as brilliant, just as green. If you’ve hiked the canyons of southern Utah, you may have already guessed what I was seeing – male Eastern collared lizards scuttling behind rocks to avoid a potential predator: me.

Collared lizards are among the more common reptiles of the arid Southwest, and also one of the more interesting ones. They’re known for their sprinting ability, reaching speeds of 16 mph when they feel threatened, often running solely on their hind legs. They’re also highly territorial – if two males are placed in the same cage, they’ll fight to the death. But what captured my interest on that warm spring morning was their flashy coloration.

More to the point, I was thinking that it didn’t seem to make sense for a desert animal to flaunt flamboyant colors. Most other desert lizards in Utah – whiptail and sagebrush lizards, side-blotched and fence lizards – are content to blend into the scenery. But male collared lizards look more at home in the jungle than in the desert, with blueish-green speckled bodies and tails, and a bright yellow head. Females are green, too, although their colors are more muted and often brownish.

It’s not uncommon for males and females of a species to sport different colors. The scientific term for this is sexual dimorphism. You see it often in birds like songbirds and ducks. Males will flash bright hues – the sublime sky blue of a mountain bluebird, the blazing orange of a Bullock’s oriole, the exuberant red, black, and yellow of a Western tanager – while females of the same species tend to be grayish or brown or dull yellow, with just a hint of the male’s glory.

This makes sense if the main purpose of coloration is camouflage. Female lizards are vulnerable to predators when bearing or caring for young, so there’s a survival advantage to matching their environment. First-year males are often colored much like females – helpful as they learn to fend for themselves. But shouldn’t the adult males want to blend in, too?

It seems male coloration also has to do with babies, but in a different way. A conspicuous male is more likely to find a mate. He’s visible. He stands out. A female lizard can find him when she needs him. Brightness also helps these lizards in another way. Remember how male collared lizards are viciously territorial? Conspicuous, vivid color helps them avoid unexpected confrontations with other males.

Of course, there’s a tradeoff here. If female lizards can easily find a male, so can predators.
Some years ago, scientists took some toy lizards, painted them in collared-lizard colors, set them out on rocks in classic lizard poses, and watched to see what would happen. As we might expect, they found that if a lizard stands out in contrast to its environment, it’s more likely to be attacked by snakes, birds, or rodents. So it’s a good thing that in addition to being fancy dressers, collared lizards are also world-class sprinters.

Forests

Forests are beyond amazing! As a field ecologist for the U.S. Forest Service, and chairing the Smithfield City Tree Committee, their branches and roots have penetrated deep into my heartwood!

A community of trees has much in common with human communities. Trees nurture and protect one another through an intricate web of roots and mycelium. When one member of the community is suffering, other members will send resources to ward off attacks, and send water and nutrients to help the stressed tree recover.

By third grade you’ve probably learned they produce oxygen and absorb green house gases, cool the earth, filter the air, provide wildlife habitat. By fifth grade add protect watersheds, provide safe drinking water, protect communities from floods and landslides. Additionally, Older trees absorb and store more carbon dioxide than younger trees, helping us fight climate change. Many species of life are found only in mature old growth forests, adding to biodiversity. They provide banks of knowledge for complex ecosystems and blueprints for natural forest processes.

As a Wilderness Ranger and recreationist, I’ve trapsed through many of Utah’s Old Growth Forests. Thanks to our National Parks, Monuments, and other public lands, we have preserved remnants of Old Growth. Magnificent ponderosa pine yet exist in Zion and Bryce Canyon national parks. I’ve found pockets of Engleman spruce in the remote parts of our national forests, along with blue spruce on Cedar Mountain and south slope of the Uintahs along river corridors. Most of old growth Douglas fir was logged off in the late 1800s.

For myself, entering an old growth forest is a spiritual experience. I stand in awe while their majesty, deep history and resilience reach deep into my core. Silence sweeps over me, interrupted by bird song, squirrel chatter, and a whisp of wind in upper branches.

For Native American cultures that developed with, and in many cases shaped the old-growth forests, they harvested medicinal plants, berries, game, or old trees and bark for ceremonial or practical use. They would tend the forest to improve ecosystem services, occasionally burning forests to complementing its utilitarian value.

Thus my alarm sounded when the U.S. House of Representatives recently passed legislation that would fast-track logging projects on federal lands, and the U.S. Forest Service has proposed opening hundreds of thousands of acres of mature (old growth) forests to commercial logging. R oads built through it will take centuries to recover. Our old growth forests are worth far more standing- economically, and for ecosystem services they provide.

Logging is warranted in younger forests, and for fire breaks near human development, while protecting water and airsheds, and sensitive species, but please, please allow Old Growth forests to continue on for the centuries it took to create them!
