Desert Solitaire: A Season in the Wilderness. Robert MacFarlane

New Mexico, the rim and interior of Grand Canyon or here in the Arches country, growing wide-spaced and solitaire from the red sands of Utah.

      The yucca is bizarre not only in appearance but in its mode of reproduction. The flowers are pollinated not by bees or hummingbirds but exclusively by a moth of the genus Pronuba with which the yucca, aided by a liberal allowance of time, has worked out a symbiotic relationship beneficial and necessary to both. The moth lays its eggs at the proper time in the ovary of the yucca flower where the larvae, as they develop, feed on the growing seeds, eating enough of them to reach maturity but leaving enough in the pod to allow the plant, assisted by the desert winds, to sow next year’s yucca crop. In return for this nursery care the moth performs an essential service for the yucca: in the process of entering the flower the moth – almost accidentally it might seem to us – transfers the flower’s pollen from anther to pistil, thus accomplishing pollination. No more; but it is sufficient.

      The wind will not stop. Gusts of sand swirl before me, stinging my face. But there is still too much to see and marvel at, the world very much alive in the bright light and wind, exultant with the fever of spring, the delight of morning. Strolling on, it seems to me that the strangeness and wonder of existence are emphasized here, in the desert, by the comparative sparsity of the flora and fauna: life not crowded upon life as in other places but scattered abroad in spareness and simplicity, with a generous gift of space for each herb and bush and tree, each stem of grass, so that the living organism stands out bold and brave and vivid against the lifeless sand and barren rock. The extreme clarity of the desert light is equaled by the extreme individuation of desert life-forms. Love flowers best in openness and freedom.

      Patterns in the sand, tracks of tiger lizards, birds, kangaroo rats, beetles. Circles and semicircles on the red dune where the wind whips the compliant stems of the wild ricegrass back and forth, halfway around and back again. On the crest of the dune is a curving cornice from which flies a constant spray of fine sand. Crescent-shaped, the dune shelters on its leeward side a growth of sunflowers and scarlet penstemon. I lie on my belly on the edge of the dune, back to the wind, and study the world of the flowers from ground level, as a snake might see it. From below the flowers of the penstemon look like flying pennants; the sunflowers shake and creak from thick green hairy stalks that look, from a snake’s viewpoint, like the trunks of trees.

      I get up and start back to the trailer. A smell of burning coffee on the wind. On the way I pass a large anthill, the domed city of the harvester ants. Omnivorous red devils with a vicious bite, they have denuded the ground surrounding their hill, destroying everything green and living within a radius of ten feet. I cannot resist the impulse to shove my walking stick into the bowels of their hive and rowel things up. Don’t actually care for ants. Neurotic little pismires. Compared to ants the hairy scorpion is a beast of charm, dignity and tenderness.

      My favorite juniper stands before me glittering shaggily in the sunrise, ragged roots clutching at the rock on which it feeds, rough dark boughs bedecked with a rash, with a shower of turquoise-colored berries. A female, this ancient grandmother of a tree may be three hundred years old; growing very slowly, the juniper seldom attains a height greater than fifteen or twenty feet even in favorable locations. My juniper, though still fruitful and full of vigor, is at the same time partly dead: one half of the divided trunk holds skyward a sapless claw, a branch without leaf or bark, baked by the sun and scoured by the wind to a silver finish, where magpies and ravens like to roost when I am not too close.

      I’ve had this tree under surveillance ever since my arrival at Arches, hoping to learn something from it, to discover the significance in its form, to make a connection through its life with whatever falls beyond. Have failed. The essence of the juniper continues to elude me unless, as I presently suspect, its surface is also the essence. Two living things on the same earth, respiring in a common medium, we contact one another but without direct communication. Intuition, sympathy, empathy, all fail to guide me into the heart of this being – if it has a heart.

      At times I am exasperated by the juniper’s static pose; something in its stylized gesture of appeal, that dead claw against the sky, suggests catalepsy. Perhaps the tree is mad. The dull, painful creaking of the branches in the wind indicates, however, an internal effort at liberation.

      The wind flows around us from the yellow haze in the east, a morning wind, a solar wind. We’re in for a storm today, dust and sand and filthy air.

      Without flowers as yet but bright and fresh, with leaves of a startling, living green in contrast to the usual desert olive drab, is a shrub known as singleleaf ash, one of the few true deciduous plants in the pinyon-juniper community. Most desert plants have only rudimentary leaves, or no leaves at all, the better to conserve moisture, and the singleleaf ash seems out of place here, anomalous, foredoomed to wither and die. (Fraxinus anomala is the botanical name.) But touch the leaves of this plant and you find them dry as paper, leathery in texture and therefore desert-resistant. The singleleaf ash in my garden stands alone along the path, a dwarf tree only three feet high but tough and enduring, clenched to the stone.

      Sand sage or old man sage, a lustrous windblown blend of silver and blue and aquamarine, gleams in the distance, the feathery stems flowing like hair. Purple flowers no bigger than your fingernail are half-revealed, half-concealed by the shining leaves. Purple sage: crush the leaves between thumb and finger and you release that characteristic odor, pungent and bittersweet, which means canyon country, high lonesome mesaland, the winds that blow from far away.

      Also worthy of praise is the local pinyon pine, growing hereabouts at isolated points, for its edible nuts that appear in good years, for its ragged raunchy piney good looks, for the superior qualities of its wood as fuel – burns clean and slow, little soot, little ash, and smells almost as good as juniper. Unfortunately, most of the pinyon pines in the area are dead or dying, victims of another kind of pine – the porcupine. This situation came about through the conscientious efforts of a federal agency known formerly as the Wildlife Service, which keeps its people busy in trapping, shooting and poisoning wildlife, particularly coyotes and mountain lions. Having nearly exterminated their natural enemies, the wildlife experts made it possible for the porcupines to multiply so fast and so far that they – the porcupines – have taken to gnawing the bark from pinyon pines in order to survive.

      What else? Still within sight of the housetrailer, I can see the princess plume with its tall golden racemes; the green ephedra or Mormon tea, from which Indians and pioneers extracted a medicinal drink (contains ephedrine), the obnoxious Russian thistle, better known as tumbleweed, an exotic; pepperweed, bladderweed, snakeweed, matchweed, skeleton weed – the last-named so delicately formed as to be almost invisible; the scrubby little wavy leaf oak, stabilizer of sand dunes; the Apache plume, poor cousin of the cliffrose; gray blackbrush, most ubiquitous and humble of desert plants, which will grow where all else has given up; more annuals – primrose, sourdock, yellow and purple beeplant, rockcress, wild buckwheat, grama grass, and five miles north across the floor of Salt Valley, acres and acres of the coral-colored globemallow.

      Not quite within eyeshot but close by, in a shady dampish secret place, the sacred datura – moonflower, moonlily, thornapple – blooms in the night, soft white trumpet-shaped flowers that open only in darkness and close with the coming of the heat. The datura is sacred (to certain cultists) because of its content of atropine, a powerful narcotic of the alkaloid group capable of inducing visionary hallucinations, as the Indians discovered long before the psychedelic craze began. How they could have made such a discovery without poisoning themselves to death nobody knows; but then nobody knows how so-called primitive man made his many other discoveries. We must concede that science is nothing new, that research, empirical logic, the courage to experiment are as old as humanity.

      Most of the plants I have named so far belong to what ecologists call the pinyon pine-juniper community, typical of the high, dry, sandy soils of the tablelands. Descend to the alkali flats of Salt Valley and you find an entirely different grouping: shadscale, four-winged saltbush, greasewood, spiny horsebrush, asters, milk vetch, budsage, galleta grass. Along the washes and the rare perennial streams you’ll find a third community: the Fremont poplar or cottonwood tree, willow, tamarisk, rabbitbrush or chamisa, and a variety of sedges, tules, rushes, reeds, cattails. The fourth plant community, in the
