Matthiessen's Wildlife in America

'And I brought you into a plentiful country, to eat the fruit thereof and the goodness thereof; but when ye entered ye defiled my land and made mine heritage an abomination.' Jeremiah 1:6

In some ways, Wildlife in America. (New York, Viking Press, 1959) by Peter Matthiessen appears to be an apology for human-caused extinction. But perhaps Matthiessen is simply being realistic when he questions whether all species really need to be protected. Should we ruin a ranching community trying to save a relictual species that only lives in one small pool in the desert, a species that would likely become extinct anyway? What about the ridiculous perfusion of species, such as the hundreds of varieties of freshwater clams the Tennessee Valley Authority spends millions of dollars protecting? What about species that, as Matthiessen puts it, have "become senile and over-specialized in their long period of isolation...unable to compete with the younger species..."? Despite the strange word choice, his point that some species fail to adapt to natural changes, is well-taken. When Panama rose out of the sea to connect North and South America many species became extinct because they could not competitively adapt to the wave of immigrants. Perhaps our rush to fight invasive species while protecting endemic species is ultimately as futile as trying to stop Panama from linking the two American continents?

(Ironically, we seem to have done precisely that with the Panama Canal, which prevents genetic exchange between many species with populations in North and South America, such as the Jaguar.)

Unfortunately, by Peter Matthiessen is ultimately unsatisfying because Matthiessen never directly answers the question of why the extinction of species matters. Too busy telling a 'balanced story' to directly confront the value of non-human species, he leaves this task to later authors, notably Rachel Carson, who argued that all life is connected and that what we do to others we eventually do to ourselves. But perhaps Matthiessen is wise to leave that argument to specialists; indeed, much of the Deep Ecology movement is an attempt to explain how species that cannot argue their own case can have inherent worth.

But let there be no mistake -- Matthiesson's opinion of the extinction crisis is clear. He is unmistakable when he argues that "the concept of conservation is a far truer sign of civilization than that spoliation of a continent which we once confused with progress." Although he doesn't deign to list specific reasons, he is at his best intoning arguments that pull at the heart and echo the damnation of the apocalypse (CF. the quote from Jeremiah above, also featured at the beginning of Wildlife in America)

"Even today, despite protection, the scattered individuals of species too long persecuted are hovering at the abyss of extinction and will vanish in our lifetimes. The slaughter [for food] has subsided this century but the vertebrate animals as a group are obscured by man's dark shadow. Such protection as is extended them too rarely includes the natural habitats they require, and their remants skulk in a lean and shrinking wilderness.

The true wilderness -- the great woods and clear rivers, the wild swamps and grassy plains whcich once were the wonder of the world -- has been larely despoiled and today's voyagers, approaching our shores through the oiled waters of the coast, are greeted by smoke and the glint of industry on our fouled seaboard, and an inland prospect of second growth, scarred landscapes, and sterile, often stinking, rivers of pollution and raw mud, the whole bedecked with billboards, neon lights, and other decorative evidence of mankind's triumph over chaos.

In many regions the greenwood not converted to black stumps no longer breathes with sound and movement, but is become a cathedral of still trees; the plains are plowed under and the praires ravaged by overgrazing and the wind of drought. Where great, wild creatures ranged, the vermin prosper."

In Search of the Elusive Elephant Tree


The Elephant Tree (Bursera microphylla) is a rare member of the Sonoran scrub community, left behind in a few relictual populations after the ebbing of the last ice age. Our amateur expedition convened to verify its rumored existence with our own senses. Lacking professional expertise, we relied on a map of hearsay and riddles. Intoning these raw directions with varying emphasis, turning the map while squinting, convincing ourselves of our own speculation, falling back into self-doubt at the next turn in the road...by faith and blind reckoning we journeyed and when we couldn't drive any more we got out and walked.



The crunch of desert gravel, second-growth ironwoods twisted like deep time, patches of magically incongruous moss growing in the deep shadows, a butterfly (Hemiluca tricolor) warming to the January morning. It seemed nothing could hide in the glorious panopticon of brilliant Sonoran sunlight. But it was only the illusion of omniscience - we knew the elusive Elephant Tree lurked somewhere in the thick desert scrub, but we didn't know where.



We pushed on. Past abandoned mines, over barbed wire and barbed cacti. The steep and gutted tracks curved around a dry valley, attained the saddle, and continued up the south-facing slope of Mt. Silverbell. There, tucked in a cozy drainage of austere smooth rock waterfalls, clinging to unlikely toeholds on the sheer wall, were the Elephant Trees; the thick trunks peeling elegantly in the sparse shadows. Fragrant limbs and resinous (juniper-like) berries carried a pungent and uniquely fragrant odor, a benediction to the dry dust desert.



We watched the sun cross the sky from our perch among them, tucked away with them in cozy niches, waiting patiently or perhaps resigned to fate, relicts in a strange world. They are safe and comfortable raising small families in their isolated enclave. We thanked them for their time and magnanomous patience when posing for our photographs. None of us wanted to leave, but we have faith now that the elusive Elephant Trees can abide without us.

You remember the San Pedro


You remember driving up out of the Santa Cruz valley from Nogales through hills and then up over a wide country of wineries where you exclaim "oh I didn't know Arizona could be like this!" We hike along the Babocomari river under the trees and watch the Great Horned Owls. The Rincons, the Mustang and Whetstone, the Burro, the Huachuca, the Canelo hills, and the Santa Ritas and Empire Mountains are all arrayed round about; the town of Elgin, the sun and the full moon and the purple-tinged shadow of the Earth.



But what you don't know is that if you follow the river you meander around the Mustang mountains and leave them standing still behind you like some kind of massive eroded stonehenge....and then you enter a great valley with cities and people and mountains all around. This is one of the last great river-valleys before the continental divide, one of the last surviving Arizona rivers, the San Pedro.



But this green ribbon snaking through an ocean of desert scrub and cactus is already dead. The aquafer has been drained and it is only a matter of time before this valley, like its neighbors, becomes dust and bones. "Man's ego is going to fill his pockets, and the river be damned." (ibid)
