By contrast with earlier Indian inhabitants, the farmers had considerable impact on the land. Most obvious was the removal of forest to make homesites, cropland, and pastures. By 1902, eight percent of the land on the Tennessee side of the Smokies and seven percent on the North Carolina side had been cleared. As settlement proceeded up a hollow farmers were confronted with steeper and steeper slopes. The inevitable results of trying to raise corn on the sides of mountains were rapid loss of fertility and then of the soil itself, as the heavy rains leached out nutrients and washed away first the humus and then the mineral soil beneath. In this wilderness where virgin land was still abundant, many mountaineers simply cleared a new patch when the old one gave out. Horace Kephart, a midwesterner who lived among such farmers on the North Carolina side early in the 20th century, recorded their approach to cultivation. They would clear land and get out two or three crops of corn.
“When corn won’t grow no more I can turn the field into grass a couple of years,” Kephart’s informant says.
“Then you’ll rotate, and grow corn again?” Kephart asks, a bit ingenuously.
“La, no! By that time the land will be so poor hit wouldn’t raise a cuss-fight.”
“But then you must move, and begin all over again.” Kephart counters. “This continual moving must be a great nuisance.”
Kephart overstates the case, however, because most stayed in one house for two to three generations, or about 50 to 75 years.
Clearing and the erosion that sometimes followed were relatively local and distinct effects of settlement. Uses of uncleared forest land had widespread, but more subtle, effects. Selected white pines and yellow-poplars were cut for lumber; oaks for shingles; and hickories mostly for firewood. Other species were put to less important, miscellaneous uses. Many plants were collected for food and dyes or for medicinal purposes. Ginseng, which has a forked root highly prized in China for its supposed medicinal and aphrodisiac values, was nearly eliminated by eager “sang” diggers who sold the roots for export. Probably even more pervasive was the influence of livestock. Hogs, and sometimes cattle and sheep, were allowed to roam the forests, grazing, browsing, and rooting for a living. Mast—acorns, chestnuts, and beechnuts—formed an important part of the diet of hogs, but these omnivorous creatures ate all sorts of plants and small animals. As anyone knows who has observed a grazed woodlot, livestock can quickly impoverish the ground and shrub layers of a forest. Grazing and browsing, along with use of fire, prevented the return of forest to the grass balds. All these uses of the forest undoubtedly changed the proportions of many tree and lesser plant species in the total forest composition. Precisely how much they did so cannot now be determined.
The impact of settlement on certain wildlife species is more easily seen. Elk disappeared about the time the earliest pioneers moved in. The beaver, an easily trapped animal, was nearly gone by the end of the 19th century. Wolves and cougars, hunted because they sometimes killed livestock—and uncomfortable in the presence of people—followed soon after. Deer, bear, and turkey persisted but in much-reduced numbers, with the bears retreating to rough, wild country in the central heights. Smaller animals fared better, although such hunted species as raccoon, opossum, and gray squirrel perhaps suffered some reduction.
About 1900 a new era began, bringing the greatest shock yet to Great Smokies ecosystems. Large lumber companies, having logged off the big timber of New England and the Great lakes states, turned their attention to the virgin stands of the Southern Appalachians. Setting up sawmills at the fringes of the mountains, they rapidly worked their way up the coves, just as Cherokees and settlers had done before them. Railroads, built to carry logs to the mills, were extended upstream as cutting progressed. In some watersheds, such as those of the Little River, Big Creek, and the Oconaluftee, nearly all species of trees were taken. In others, such as Abrams Creek, West Prong of the Little Pigeon, and Cataloochee, cutting was selective. By the late 1920s, logging, added to settlement practices, had at least partially cleared more than 60 percent of the land in the Great Smoky Mountains.
Though for a time it proved an economic boon, logging was easily the most destructive form of land use the region was ever subjected to. The removal of forest cover and the skidding of logs down steep mountainsides caused widespread erosion. This weakened the foundation for regrowth and clogged streams with sediment, thereby reducing their quality for sustaining aquatic life. In the wake of logging came forest fires, probably the worst these mountains have seen. Heaps of dried branches trimmed from logs made perfect tinder for fires started by engine sparks, careless matches, or lightning strikes. In the 1920s disastrous fires roared up the East Prong of Little River, up Forney Creek to Clingmans Dome, and over the slopes around Charlies Bunion. Scars from some of these fires have still not healed today.
