Reforestation, if several indigenous species are used, can provide other benefits in addition to financial returns, including restoration of the soil, rejuvenation of local flora and fauna, and the capturing and sequestering of 38 tons of carbon dioxide per hectare per year. [12]
A 2020 report estimated sequestration in forests (so including capture) at US$35 for small quantities to US$280 per tonne for 10% of the total required to keep to 1.5 C warming. [182] But there is risk of forest fires releasing the carbon.
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 km 2) 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.
In 2020, the world had a total forest area of 4.06 billion ha, which was 31 percent of the total land area. This area is equivalent to 0.52 ha per person [2] – although forests are not distributed equally among the world's people or geographically. The tropical domain has the largest proportion of the world's forests (45 percent), followed by ...
Carbon farming enhances carbon sequestration in the soil. Carbon farming is a set of agricultural methods that aim to store carbon in the soil, crop roots, wood and leaves. The technical term for this is carbon sequestration. The overall goal of carbon farming is to create a net loss of carbon from the atmosphere. [1]
These forests have long cold winters and short cool summers. Precipitation can reach over 200 centimeters per year, typically in the form of snow. Because of the cold climate in the boreal forests, the growing season is three months long. Boreal forests are made up of evergreen trees, mosses, and lichens. [12]
A Quarter Century US Forest Disturbance History from Landsat – the NAFD-NEX Products. Eastern forests cover about 384 million acres (1,550,000 km 2) and are predominantly broadleaf (74%), with the exception of extensive coniferous forests and plantations in the southern coastal region. These are largely in private ownership (83%).
An important consideration in such efforts is that forests can turn from sinks to carbon sources. [25] [26] [27] In 2019 forests took up a third less carbon than they did in the 1990s, due to higher temperatures, droughts [28] and deforestation. The typical tropical forest may become a carbon source by the 2060s. [29]
