In the United States, deforestation was an ongoing process until recently. Between 2010 and 2020, the US forests increased 0.03% annually, according to FAO (Food and Agriculture Organization of the United Nations).

Native Americans cleared millions of acres of forest for many reasons, including hunting, farming, berry production, and building materials. Prior to the arrival of European-Americans, about one half of the United States land area was forest, about 1,023,000,000 acres (4,140,000 km2) estimated in 1630. Forest cover in the Eastern United States reached its lowest point in roughly 1872 with about 48 percent compared to the amount of forest cover in 1620. The majority of deforestation took place prior to 1910 with the Forest Service reporting the minimum forestation as 721,000,000 acres (2,920,000 km2) around 1920. The forest resources of the United States remained relatively constant through the 20th century. The Forest Service reported total forestation as 766,000,000 acres (3,100,000 km2) in 2012. A 2017 study estimated 3 percent loss of forest between 1992 and 2001.
