Forests of the United States

It has been estimated that before European settlement, forests in the United States covered nearly 1,000 million acres (4,000,000 km2). On the other hand, the arrival of Europeans caused a decline in native populations, and since the natives were largely agricultural, this caused reforestation of agricultural lands. Since the mid-1600s, about 300 million acres (1,200,000 km2) of forest have been cleared, primarily for agriculture during the 19th century. Today about one-third of the nation is forested. While total forest area has been relatively stable for the last 100 years (currently about 747 million acres (3,020,000 km2)), there have been significant regional shifts in the area and composition of the nation's forests.
