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] The forest resources of the United States remained relatively constant through the 20th century. [3]
It has been estimated that before European settlement, forests in the United States mainland covered nearly 1 billion acres (4,000,000 km 2). [1] Since the mid-1600s, about 300 million acres (1,200,000 km 2) of forest have been cleared, primarily for agriculture during the 19th century.
The regions with the highest tropical deforestation rate between 2000 and 2005 were Central America—which lost 1.3% of its forests each year—and tropical Asia. [49] In Central America , two-thirds of lowland tropical forests have been turned into pasture since 1950 and 40% of all the rainforests have been lost in the last 40 years. [ 66 ]
Map of wood-filled areas in the United States, circa 2000 [1] 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]
This amounts to an average annual deforestation rate of 1.14%. [40] Between 2000 and 2005 the rate accelerated to 1.43% per annum. However, with a long history of policy and laws towards environmental protection, deforestation rates of primary cover have decreased 35% since the end of the 1990s thanks to a strong history of conservation ...
Deforestation in Brazil is projected to hit a historic low by 2025, a government official told reporters this week. The president of Ibama — Brazil’s environmental enforcement agency — told ...
Changes in forest area (like deforestation) may follow a pattern suggested by the forest transition (FT) theory, [9] whereby at early stages in its development a country is characterized by high forest cover and low deforestation rates (HFLD countries). [10]
The yearly precipitation rate is between 20 and 60 inches in the form of rain or snow. Temperatures in temperate forests range from -22 degrees Fahrenheit to 86 degrees Fahrenheit. Temperate Forests within the United States are found in the Eastern region. Temperate forests can support a variety of species due to the large amount of rainfall.
