“There is a tree. At the downhill edge of a long, narrow field in the western foothills of the La Sal Mountains -- southeastern Utah. A particular tree. A juniper. Large for its species -- maybe twenty feet tall and two feet in diameter. For perhaps three hundred years this tree has stood its ground. Flourishing in good seasons, and holding on in bad times. "Beautiful" is not a word that comes to mind when one first sees it. No naturalist would photograph it as exemplary of its kind. Twisted by wind, split and charred by lightning, scarred by brushfires, chewed on by insects, and pecked by birds. Human beings have stripped long strings of bark from its trunk, stapled barbed wire to it in using it as a corner post for a fence line, and nailed signs on it on three sides: NO HUNTING; NO TRESPASSING; PLEASE CLOSE THE GATE. In commandeering this tree as a corner stake for claims of rights and property, miners and ranchers have hacked signs and symbols in its bark, and left Day-Glo orange survey tape tied to its branches. Now it serves as one side of a gate between an alfalfa field and open range. No matter what, in drought, flood heat and cold, it has continued. There is rot and death in it near the ground. But at the greening tips of its upper branches and in its berrylike seed cones, there is yet the outreach of life. I respect this old juniper tree. For its age, yes. And for its steadfastness in taking whatever is thrown at it. That it has been useful in a practical way beyond itself counts for much, as well. Most of all, I admire its capacity for self-healing beyond all accidents and assaults. There is a will in it -- toward continuing to be, come what may.”

“The thing about trees is that they know what to do. When a leaf loses its colour, it's not because its time is up and it's dying, it's because the tree is taking back into itself the nutrients the leaf's been holding in reserve for it, out there on the twig, and why leaves change colour in autumn is because the tree is preparing for winter, it's filling itself with its own stored health so it can withstand the season. Then, clever tree, it literally pushes the used leaf off with the growth that's coming behind it. But because that growth has to protect itself through winter too, the tree fills the little wound in its branch or twig where the leaf was with a protective corky stuff which seals it against cold and bacteria. Otherwise every leaf lost would be an open wound on a tree and a single tree would be covered in thousands of little wounds. Clever trees.”

“When you look at a tree, se it for its leafs, its branches, its trunk and the roots, then and only then will you see the tree”

“The affinities of all the beings of the same class have sometimes been represented by a great tree.I believe this simile largely speaks the truth. The green and budding twigs may represent existing species; and those produced during former years may represent the long succession of extinct species. At each period of growth all the growing twigs have tried to branch out on all sides, and to overtop and kill the surrounding twigs and branches, in the same manner as species and groups of species have at all times overmastered other species in the great battle for life. The limbs divided into great branches, and these into lesser and lesser branches, were themselves once, when the tree was young, budding twigs; and this connection of the former and present buds by ramifying branches may well represent the classification of all extinct and living species in groups subordinate to groups. Of the many twigs which flourished when the tree was a mere bush, only two or three, now grown into great branches, yet survive and bear the other branches; so with the species which lived during long-past geological periods, very few have left living and modified descendants. From the first growth of the tree, many a limb and branch has decayed and dropped off; and these fallen branches of various sizes may represent those whole orders, families, and genera which have now no living representatives, and which are known to us only in a fossil state. As we here and there see a thin straggling branch springing from a fork low down in a tree, and which by some chance has been favoured and is still alive on its summit, so we occasionally see an animal like the Ornithorhynchus or Lepidosiren, which in some small degree connects by its affinities two large branches of life, and which has apparently been saved from fatal competition by having inhabited a protected station. As buds give rise by growth to fresh buds, and these, if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever-branching and beautiful ramifications.”

“A botanist would have been stumped, coming across a tree like this one. Yet, if we are to judge a tree by its fruit, it was clearly an avocado. I picked the fruit, sliced it open, and tasted it to make sure. There was no doubt in my mind. If it looks like an avocado and tastes like an avocado, it has got to be an avocado. However, the tree itself had a white bark like that of a birch and its sap tasted like birch juice. Its leaves were delicate like that of a cypress, while its trunk and the root system reminded me of a baobab. Could it be that someone had grafted an avocado on to a baobab tree? And if so, why the bark so white and the leaves so, well, feathery, and delicate yet bold like a dragonfly’s wing? Why is there not another tree like it nearby? Where had the seed of this tree come from? I had no answer. So, I put the seed of the fruit in my pocket and took it home with me to see if I could make it grow.”

“A tree is alive, and thus it is always more than you can see. Roots to leaves, yes-those you can, in part, see. But it is more-it is the lichens and moss and ferns that grow on its bark, the life too small to see that lives among its roots, a community we know of, but do not think on. It is every fly and bee and beetle that uses it for shelter or food, every bird that nests in its branches. Every one an individual, and yet every one part of the tree, and the tree part of every one.”
