Burning Desires and Incendiary Thoughts

Horseshoe Two Fire, Chiricahuas

Hot winds batter the landscape, sucking whatever moisture they can coax from desiccated plants.  Record-breaking temperatures challenge the survival skills of wildlife, as they and we wait for the merciful monsoonal rains, should they come in a month.  We wait and watch, knowing that the first plume of smoke to rise skyward could create a blazing inferno defying our feeble but expensive efforts to limit the damage.

Arizona has endured droughts and heat waves before, but there are strong signs that human activities are exacerbating the challenges faced by the more-than-human world.   The summer of 2011 saw huge tracts of forest burn up in the Southwest.  I witnessed the dramatic Horseshoe Two Fire in the Chiricahuas, but in a summer of exceptional fires in both Arizona and New Mexico, that one was just the tip of the melting iceberg.  That was the summer of the Wallow Fire in Arizona (largest in history), the Conchos Fire in New Mexico (also the largest recorded there), the Monument Fire in the Huachucas (which consumed the home and irreplaceable insect collections of one of my friends), and many fires in northern Mexico, where suppression was not even attempted.  More than 2.1 million acres burned, over twice the previous record set in 2006 for these two states.  Megafires.  Unprecedented.  Shocking.

Where Do Toe-biters Go When It Rains?

Curiosity is a well-known field mark of a naturalist, and I have learned to indulge my curiosity when an opportunity arises.  Some years ago, I stayed with friends in the Chiricahua Mountains of SE Arizona, one of the dramatic “sky islands” of the Southwest.  Back in the cooler, wetter Pleistocene, the forests marched across the valleys, allowing free commerce for animals and plants among the ranges.  As conditions warmed and dried, the forests retreated to higher elevations, trapping survivors on habitat islands.  Continue reading

The Call of the Wild: Are We Listening?

Deep within us we carry the genetic legacy of our distant ancestors.  When we hear the mournful howl of a wolf, there is a shiver down our spine, a surge of adrenalin that we cannot control.  We respond automatically and positively when we view a cute and cuddly creature or one of the “charismatic megafauna.”  For some people, the call of the wild has become more of a whisper, but it’s there.

Recently I gave the keynote address for the 2011 Regional Urban Wildlife Symposium sponsored by the Open Space Alliance of Yavapai County, Arizona.  Joe Phillips videotaped it and posted it on You Tube, so here it is if you want to hear and see my take on THE CALL OF THE WILD: ARE WE LISTENING?

Megadiversity of Moths

The scene:  The Madrean Sky Islands, an archipelago of dozens of mountain ranges that unify the spirits of the Rockies and the Sierra Madre, the Sonoran and Chihuahuan Deserts.  This is a land of astonishing diversity by almost any measure.  The following story is based on a visit more than a decade ago to the Ash Canyon property of Noel McFarland in the SE part of the Huachucas, a range noted for abundant and varied birds, mammals, and reptiles.

But birds, mammals, and herps are not why I came to see Noel McFarland.  He is a collector of diversity with a twist all his own.  McFarland knows moths.  I follow him through several rooms where he works.  Noel collects more than moths, it seems, and twenty years’ accumulation of boxes, books, papers, and other memorabilia fills his spaces the way floral diversity fills a rainforest.  Continue reading

Deepening the Time Scale: A Puzzle in Sycamore Canyon

Though each organism is inherently a time traveler, its genes a partial chronicle of its evolutionary history, we may be the sole species to be able to reflect on that deeper history.  People with deep imaginations can visualize the ape in our behaviors, the prototypical vertebrate in our embryos, the symbiotic merger reflected in our mitochondria.  Some can look at a hillside and envision it as a product of tectonic upheavals, erosional incisions and depositions, the lithification that turned sediment into rock that has weathered into a substrate supporting juniper, cactus, and spiny lizard.  With some training, there is hope for those of us who don’t normally see so well.  Our temporal blinders may be lifted, our spirits uplifted by the joys of discovery and insight.  Informed imagination – that greatest of time machines – can take us further toward understanding the Sky Islands than mere physical descriptions ever will.  Join me, then, for a little time travel, not to see it all (who has time?), but for a sample of how informed imagination works.            Continue reading

BORDERLANDS MUSINGS
By Walt Anderson
Four decades ago, I was a grad student in the School of Natural Resources at the University of Arizona in Tucson. Well before Arizona gained its strong reputation as a hotspot for American birding, there was a small community of birders who sought out the neotropical specialties that crossed the border and the eastern vagrants that popped up now and then in desert oases. There were seasoned experts like Gale Monson, whose knowledge of Southwest birds was encyclopedic, and ragtag graduate students like Carroll Littlefield, an expert on Sandhill Cranes, and Ted Parker, later considered by many as the superstar of birders and field ornithologists. There was none of the competitive, obsessive listing that later infected the birding world, a narrow-minded focus on seeing and ticking off species as fast as possible, the interest in each bird satisfied by a mere checkmark. No, these were naturalist birders, keen observers who sought to learn about the entire ecosystems in which birds were a part. Where a bird nested, what it ate, how it migrated or molted—such were the questions that occupied the curiosities of this generation of field biologists.

Whenever possible, we would load up a tank of gas at twenty-some cents per gallon and take off to one of our favorite oases, ostensibly to bird, but even more so to explore wild places and experience the joys of discovery in nature. Often our paths took us through the dusty border town of Douglas, Arizona under the appalling smokestacks of Phelps Dodge, then likely the largest single point-source of pollution in the Southwest, if not America as a whole. Continuing east along teeth-chattering gravel roads, we passed through the “malpai” badlands of rocky hills, creosote bush, ocotillo, and occasional flash-flood-prone desert washes. We’d pass the old ranch of Texas John Slaughter, where we’d stop to glass for whistling ducks, Neotropic Cormorants, Vermilion Flycatchers, and other oasis birds drawn to the artesian springs there (later much of this became the San Bernardino National Wildlife Refuge established primarily to help save native fishes of the Rio Yaqui watershed).

Our final destination lay at the end of the road just into New Mexico right where that state intersects with Arizona and Sonora: a green finger of Mexican riparian woodland, Guadalupe Canyon. We would stop up at the Magoffin ranch house to pay our respects and get their generous permission; then we’d explore the main canyon of large cottonwoods and sycamores and venture up thorny side washes for arid-adapted specialties. At night, we would listen and watch for the Ridgeway’s Whip-poor-will (now called Buff-collared Nightjar), one of the species that barely entered the United States at this point.

We were certainly aware of the proximity of Mexico, but only because we could count birds seen on this side of the weak barbed-wire fence for our U.S. list. At night as we lay in sleeping bags under the canopy of trees and the overarching dome of stars in an unpolluted sky, we might awaken to the footsteps and breathing of men, usually alone or with one companion, heading north to work, seeking employment opportunities that were unavailable south of the border. We might meet them at dusk or in early morning, where a polite exchange of “Buenos Dias” or “Hola” along with shy smiles would be the extent of our interchange.   Continue reading
