An important consideration regarding carbon sequestration is that forests can turn from a carbon sink to a carbon source if plant diversity, density or forest area decreases, as has been observed in different tropical forests [64] [65] [66] The typical tropical forest may become a carbon source by the 2060s.

Forests have an enormously important role to play in the global ecosystem. Forests produce approximately 28% of the Earth's oxygen (the vast majority being created by oceanic plankton), [3] they also serve as homes for millions of people, and billions depend on forests in some way. Likewise, a large proportion of the world's animal species live ...
Forest ecosystems have come to be seen as the most important component of the biosphere, [5] and forestry has emerged as a vital applied science, craft, and technology. A practitioner of forestry is known as a forester. Another common term is silviculturist.
The forest is a natural system that can supply different products and services. Forests supply water, mitigate climate change, provide habitats for wildlife including many pollinators which are essential for sustainable food production, provide timber and fuelwood, serve as a source of non-wood forest products including food and medicine, and contribute to rural livelihoods.
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 ...
The International Day of Forests was established on the 21st day of March, by resolution of the United Nations General Assembly on November 28, 2013. [1] Each year, various events celebrate and raise awareness of the importance of all types of forests, and trees outside forests, for the benefit of current and future generations.
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. [8]
Monitoring of wildlife populations is an important part of conservation because it allows managers to gather information about the status of threatened species and to measure the effectiveness of management strategies. Monitoring can be local, regional, or range-wide, and can include one or many distinct populations.
