Deforestation or forest clearance is the removal and destruction of a forest or stand of trees from land that is then converted to non-forest use. [1] Deforestation can involve conversion of forest land to farms, ranches, or urban use. About 31% of Earth's land surface is covered by forests at present. [2]
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]
The Kyoto Protocol article 3.3 thus requires mandatory LULUCF accounting for afforestation (no forest for last 50 years), reforestation (no forest on 31 December 1989) and deforestation, as well as (in the first commitment period) under article 3.4 voluntary accounting for cropland management, grazing land management, revegetation and forest ...
According to Food and Agriculture Organization's (FAO) Global Forest Resources Assessment 2020, an estimated 420 million hectares (1.0 billion acres) of forest have been lost worldwide through deforestation since 1990, but the rate of forest loss has declined substantially. In the most recent five-year period (2015–2020), the annual rate of ...

Forests in the United States can be categorized into three main forest biomes, they are boreal, temperate, or sub-tropical based on the location and climate of the forest. Each of these biomes faces various threats of deforestation , urban development, [ 2 ] soil compaction , species extinction, unmanaged recreational use, invasive species , or ...
