Reforestation is the practice of restoring previously existing forests and woodlands that have been destroyed or damaged. The prior forest destruction might have happened through deforestation , clearcutting or wildfires .
Three important purposes of reforestation programs are for harvesting of wood, for climate change mitigation, and for ecosystem and habitat restoration purposes. One method of reforestation is to establish tree plantations, also called plantation forests. They cover about 131 million ha worldwide, which is 3% of the global forest area and 45% ...
[8] It is important to conserve the rainforest because many resources for things we use everyday come from the rainforest, including rubber for tires and spices such as cinnamon and many other common items. [9] It is imperative to life on earth that the rainforest be conserved, as the trees take in carbon dioxide to provide oxygen.
Forest recovery resulting in net increases in forest extent can occur by means of spontaneous regeneration, active planting, or both. [11] [12]There are two main paths in reforestation, one emerging from economic development and another from forest scarcity. [12]
Forest restoration may include simply protecting remnant vegetation (fire prevention, cattle exclusion etc.) or more active interventions to accelerate natural regeneration, [8] as well as tree planting and/or sowing seeds (direct seeding) of species characteristic of the target ecosystem. Tree species planted (or encouraged to establish) are ...
Sustainable Development Goal 15 (SDG 15 or Global Goal 15) is about "Life on land".One of the 17 Sustainable Development Goals established by the United Nations in 2015, the official wording is: "Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss". [1]
When the purpose is reforestation, it is known as aerial reforestation. Aerial seeding is considered a broadcast method of seeding. [1] It is often used to spread different grasses and legumes to large areas of land that are in need of vegetative cover after fires. [2] Large wildfires can destroy large areas of plant life resulting in erosion ...
In comparison, reforestation means re-establishing forest that have either been cut down or lost due to natural causes, such as fire, storm, etc. Nowadays, the boundaries between afforestation and reforestation projects can be blurred as it may not be so clear what was there before, at what point in time.
