Humans have altered this area for a long time; Cherokees farmed extensively in this area, mostly in the valleys
Today, agriculture is widespread in both the valleys and on the plateaus; most original forest has been cut and/or burned.
Historically, fire was the dominant type of disturbance, but there is little information on frequency or size of fires.
Since European colonization, much of the forest cutting has been to produce charcoal for iron furnaces.
Mining has also had an impact in the area: coal, bauxite, barium ore, ocher have been strip-mined. |
