Rewatering the West: Learning from Beavers and the Zuni

This summer may be a harsh preview of what’s ahead for parts of the Rocky Mountain West. The story for those who don’t live here is that we had a very stingy snowpack and a too-warm March and April. So when May came, we got none of the delicious torrent of snowmelt, the swollen rivers, the copious irrigation water, the full reservoir ponds, or the saturated soil. Instead we got a tiny surge of water followed by barely trickling streams, something I’ve never seen in my life here in Colorado.

We knew it was coming. The US Department of Agriculture has done wonderful things with “SNOTELS”, which stands for snowpack telemetry and gives anyone interested real-time information on volumes of snow-water equivalents. SNOTELS use giant rubber bladders filled with antifreeze, pressure transducers to measure weight, and radio transmitters to communicate. So an angler, a rafting guide, or a rancher can sit in their kitchen in March and April, study the information from a distant SNOTEL and make plans for the summer.

For lots of ranchers, it meant cutting way back on cattle numbers; for fishing guides it’s meant warm shallow waters, and for rafting guides, it’s meant shortened seasons.

Things don’t look nice for the Rocky Mountain states in the next 30-50 years. If the planet continues to warm as climatologists predict, the average temperature of Colorado (for example) will be 2.5 degrees to 5.5 degrees warmer than state averages in the late 20th century. Warmer air means higher evapotranspiration rates to the tune of approximately a 15% increase. So our soils will dry out more quickly, our reservoirs will evaporate faster, and our plants (grasses and trees) will dry out more quickly. I don’t know how much of this can be mitigated. Still, it’s certainly worth exploring every possible solution to keep some moisture in the ground and to protect our subsurface and surface water supplies. And some of the best solutions may be pretty low tech.

Start with the beaver, that buck-toothed little dam builder with the webbed feet and the flat tail. When a beaver builds a dam on a streambed, it changes the entire hydrology of the area rather radically. Read more »

Endangered Species and the Sovereignty of the West

by Mark Harvey

Hollow Horn of the Sioux Tribe

There was a time when the West was truly wild. I don’t mean the gun fights in saloons, the stampede of a thousand cattle, or stagecoach robberies on the high plains. But it wasn’t that long ago when every river from what is now Kansas to the Pacific Ocean ran its course without a dam or diversion, tens of millions of buffalo grazed on the rich grasslands, and beavers built thousands and thousands of ponds across the Rockies. It was but a blink of the eye since apex predators like Grizzly bears and Wolves ruled the land from north to south.

One man who witnessed a nearly virgin West was John K Townsend, the first trained naturalist to travel from St. Louis to what is today Oregon. In a book called Journey Across the Rocky Mountains to the Columbia River, Townsend shares images of a trip that began in 1834, not long after Louis and Clark first made their expedition. Even in bustling St. Louis, where Townsend was provisioning, there were foretokens of what was ahead in the untrammeled country he was to cross. He describes the sight of a hundred Saque Indians with shaved heads and painted in stripes of “fiery red and deep black, leaving only the scalping tuft, in which was interwoven a quantity of elk hair and eagle’s feathers.”

Just a month into the trip, Townsend encounters a trapper who tells the story of having his horse and rifle stolen by Otto Indians in the middle of winter while still far from any settlement. When Townsend asks the trapper how he survived without food on his journey home, the trapper says, “Why, set to trappin’ prairie squirrels with little nooses made out of the hairs of my head.”

About six weeks into the crossing, Townsend describes the various wolves slinking about the camp looking for scraps of food. By his narrative, he does not seem a bit afraid of them but describes the encounters as “amusing to see the wolves lurking like guilty things around these camps seeking for the fragments that may be left.” The contrast of this naturalist’s comfort around wild animals camped out in the true wilds with just a horse, compared to some of today’s self-styled “mountain men,” is stark. For if you turn on most any AM radio station in Montana, Wyoming, or Colorado today, you’ll hear angry men sealed in 6,000-pound pickup trucks on major highways, calling in to talk shows to express their fear and loathing of wolves. My how soft we’ve become. Read more »

Restoring Eden: Our Long Journey to Recover American Lands

by Mark Harvey

American Beavers (Castor Canadensis)

If you submitted yourself to the idiotic torture over last week’s battle to elect the speaker of the house for the 118th Congress, then you deserve a break from that idiocy and the chance to think about something else. American politics at the national level make toxic uranium dumps seem like tea gardens. The petulance and pettiness of many of our politicians make daycare centers seem like bastions of diplomatic protocol.

But there are things to think about in this great land that are a salve and rampart against the most cretinous of our congresspersons: the many efforts of Americans to steward lands back to health.

Let’s not mince words: in a few hundred years on this continent, we have trashed millions of acres and imperiled thousands of species. From Seattle to Tampa, from Galveston to Fargo, and even in parts of Alaska, what we’re facing is the aftermath of a resource-eating orgy. Now we face the unpleasant hangover and picking up all the broken bottles. But some Americans with pluck, eternal optimism, can-do, and deep allegiance to the land are doing it. Read more »
