“He who hopes for spring with upturned eye never sees so small a thing as Draba. He who despairs of spring with downcast eye steps on it, unknowing. He who searches for spring with his knees in the mud finds it, in abundance.”

“One swallow does not make a summer, but one skein of geese, cleaving the murk of a March thaw, is the spring.”

“A conservationist is one who is humbly aware that with each stroke [of the axe] he is writing his signature on the face of the land.”

“Some paintings become famous because, being durable, they are viewed by successive generations, in each of which are likely to be found a few appreciative eyes. I know a painting so evanescent that it is seldom viewed at all, except by some wandering deer. It is a river who wields the brush, and it is the same river who, before I can bring my friends to view his work, erases it forever from human view. After that it exists only in my mind's eye. Like other artists, my river is temperamental; there is no predicting when the mood to paint will come upon him, or how long it will last. But in midsummer, when the great white fleets cruise the sky for day after flawless day, it is worth strolling down to the sandbars just to see whether he has been at work.”

“This whole effort to rebuild and stabilize a countryside is not without its disappointments and mistakes... What matter though these temporary growing pains when one can cast his eye upon the hills and see hard-boiled farmers who have spent their lives destroying land now carrying water by hand to their new plantations”

“One of the penalties of an ecological education is that one lives alone in a world of wounds. Much of the damage inflicted on land is quite invisible to laymen. An ecologist must either harden his shell and make believe that the consequences of science are none of his business, or he must be the doctor who sees the marks of death in a community that believes itself well and does not want to be told otherwise.”

“There are some who can live without wild things and some who cannot.”
