But wait a minute! What about the grasslands which occupy 40% of the earth’s land surface (World Resources Institute)? “Crop production” and “food production” are NOT synonymous. This is the flawed mindset that agriculture means crop production and that farming means cropping. This mindset assumes that pasture-based livestock systems are less productive than cropping systems, and that pasture-based systems are less productive than confinement systems. These assumptions usually compare single-species pasture-based livestock systems on less productive soils with crop production on highly productive soils. Rarely are integrated, multiple species grazing systems considered, nor are these two philosophies compared on soils of equal productivity. The irony here is that this country’s most productive soils developed under the Midwest’s tall grass prairie. And the prairie was well managed by the Native Americans. But wait! Didn’t the Native Americans “live lightly on the land?” Once again, we’re confronted with a badly flawed worldview.
“When Lewis and Clark headed west … they were exploring not a wilderness but a vast pasture managed by and for Native Americans” (Lott, 2002).
Images of woodlands, unsullied by human presence, and of the Great Plains (or Prairie, in Canada) with its huge herds of bison (Bison bison) may come to mind when we think about pre-European North America. But this popular image of pre-Columbian North America as a pristine paradise is incorrect. When Europeans first arrived in North America, they found anything but a primeval landscape. Instead, they encountered a land significantly altered by humans through the use of fire, sophisticated agricultural techniques, mining, and road and mound building (Mann, 2006).
“At the time of Columbus the Western Hemisphere had been thoroughly painted with the human brush. Agriculture occurred in as much as two-thirds of what is now the continental United States, with large swathes of the Southwest terraced and irrigated. Among the maize fields in the Midwest and Southeast, mounds by the thousand stippled the land. The forests of the eastern seaboard had been peeled back from the coasts, which were now lined with farms. Salmon nets stretched across almost every ocean-bound stream in the Northwest. And almost everywhere there was Indian fire.” (Mann, 2006)
From fire created and maintained prairies and managed forests, to earthworks and settlements, the American landscape by the time of European contact had already endured thousands of years of modification by large Native American populations. The pristine wilderness view, to a large extent, is the invention of 19th-century romantic and primitivist writers like Henry David Thoreau and Henry Wadsworth Longfellow (Denevan, 1992). The reality is that the impact of native peoples was nearly ubiquitous, even in areas with comparatively sparse Indian populations. Many scholars now believe there were more than 90 million inhabitants of the New World when Christopher Columbus first set sail for the Indies (Denevan, 1996).
The climate responsible for the eastward extension of the tall grass prairies disappeared thousands of years ago, but manmade fires preserved it in areas such as southern Wisconsin, Illinois, Indiana, and parts of Ohio by halting the process of ecological succession which would have resulted in these areas becoming dominated by trees as the natural climax vegetation (Williams, 1989). Further east, forest management with fire produced an environment that benefited wildlife and humans. The effectiveness of these practices is demonstrated by the observations that bison (Bison bison) once roamed along the east coast from New York to Georgia (Mann, 2006) and that elk (Cervus canadensis) have been observed in every continental state except Florida (Manning, 1997). “When Lewis and Clark headed west … they were exploring not a wilderness but a vast pasture managed by and for Native Americans” (Lott, 2002).

“When the newcomers [European settlers] moved west, they were preceded by a wave of disease and then a wave of ecological disturbance. The former crested with fearsome rapidity; the latter sometimes took more than a century to tamp down, and it was followed by many aftershocks. “The virgin forest was not encountered in the sixteenth and seventeenth centuries,” wrote historian Stephen Pyne, “it was invented in the late eighteenth and early nineteenth centuries.” Far from destroying pristine wilderness, that is, Europeans bloodily created it.
“By 1800 the hemisphere was thick with artificial wilderness. If “forest primeval” means woodland unsullied by the human presence, Denevan has written, there was much more of it in the nineteenth century than in the seventeenth.
“The product of demographic calamity, the newly created wilderness was indeed beautiful. But it was built on Indian graves and every bit as much a ruin as the temples of the Maya.”
Despite the horrible pestilences of the 15th through 18th centuries, the physical health and condition of the plains-dwelling Native Americans were far more robust than those of their contemporary Europeans in the 19th century. Explorers who first contacted the Kiowa and other bison-dependent nations documented that the diet of these people was almost exclusively meat-based. Observations made during the 1830s recorded that it was rare to find a male of the Cheyenne tribe less than six feet (183 cm) tall, while among the Osage people in the Kansas area few were less than six feet tall, and some were seven feet (213 cm) tall (Catlin, 1844). In addition, there was no evidence of the chronic diseases already observed in European populations (Taubes, 2008).
The European settlers suffered from their own flawed mindsets. They referred to the Great Plains as the Great American Desert, because of its lack of trees. This reflected the European farming mindset typical of the 18th and 19th centuries (Manning, 2007). They failed to recognize the value of grassland and its true potential, as well as its unique requirements. Governmental policies and the settlers’ farming practices were ill-suited to the Great Plains. Areas of natural grassland, the result of an interaction between climate, topology, soil, plant, grazing animals, and man-made fire, were plowed out for crop production. The topsoil, our nation’s greatest natural resource, was no longer protected (and increased) by a protective layer of an adapted perennial plant community. When the next drought occurred, as they periodically do in that region, the catastrophe known as then dust bowl began. Top soil was lost at a phenomenal rate. By 1934, The Yearbook of Agriculture announced that “100 million acres have lost all or most of their topsoil, another 125 million acres are about to and 35 million acres cannot grow crops of any kind.”
"The ultimate meaning of the dust storms of the 1930s was that America as a whole, not just the plains, was badly out of balance with its natural environment. Unbounded optimism about the future, careless disregard of nature’s limits and uncertainties, uncritical faith in Providence, devotion to self-aggrandizement - all these were national as well as regional characteristics." Robert Worster
I recently attended the 11th Annual Oregon State University Extension Small Farms Conference. There were many young people among the six hundred people attending. I find this exciting and encouraging, since the average age of this nations farmers, a steady decreasing group, has been increasing for many years. The future of agriculture in this country depends upon young people taking up the calling of producing food for those who don’t. I learned a lot and met a number of interesting folks. It is critical, I believe, that these young farmers understand that grass farming is the agricultural model for the 21st century.

"The Last of the Virgin Sod"
by Rudolph Ruste
We broke today on the homestead
The last of the virgin sod,
And a haunting feeling oppressed me
That we’d marred a work of God.
A fragrance rose from the furrow,
A fragrance both fresh and old:
It was fresh with the dew of morning,
Yet aged with time untold.
The creak of leather and clevis,
The rip of the coulter blade,
And we wreck what God with the labor
Of a million years had made.
I thought, while laying the last land,
Of the tropical sun and rains,
Of the jungles, glaciers and oceans
Which had helped to make these plains.
Of monsters, horrid and fearful,
Which reigned in the land we plow,
And it seemed to me so presumptuous
Of man to claim it now.
So when, today on the homestead,
We finished the virgin sod,
Is it strange I almost regretted
To have marred that work of God?
