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 km 2) around 1920. [2]
In 2008, Brazil's government announced a record rate of deforestation in the Amazon. [138] [139] Deforestation jumped by 69% in 2008 compared to 2007's twelve months, according to official government data. [140] Deforestation could wipe out or severely damage nearly 60% of the Amazon rainforest by 2030, according to a 2007 report from WWF. [141]

In the United States, the forest cover by state and territory is estimated from tree-attributes using the basic statistics reported by the Forest Inventory and Analysis (FIA) program of the Forest Service. [2] Tree volumes and weights are not directly measured in the field, but computed from other variables that can be measured. [3] [4]
AGUA CLARA, Brazil (AP) — Forest loss in Brazil’s Amazon dropped by 30.6% compared to the previous year, officials said Wednesday, the lowest level of destruction in nine years. In a 12-month span, the Amazon rainforest lost 6,288 square kilometers (2,428 square miles), roughly the size of the U.S. state of Delaware.

Deforestation in Brazil — which threatens the Amazon Rainforest, pictured above, — could hit an all-time low in the next 1-2 years, one government official said this week.
Africa had the largest annual rate of net forest loss in 2010–2020, at 3.9 million ha, followed by South America, at 2.6 million ha. The rate of net forest loss has increased in Africa in each of the three decades since 1990. It has declined substantially in South America, however, to about half the rate in 2010–2020 compared with 2000–2010.
