Question

write notes on Reforestation​

Answer 1

Answer:

reforestation

Explanation:

Reforestation is the re-growing of forests that have previously been cut down using tree species that are native to the geographic area. Another term for reforestation is afforestation, the practice of restoring forests that used to exist but had been cut down. The resurgent forest can benefit the environment, preserve endangered species and renew valuable resources, and can also remove carbon dioxide from the atmosphere, which benefits the effort to slow global warming.Reforestation can either occur naturally or it can be managed by people. In natural reforestation, an area is simply left undisturbed by human activity. Seedlings in the ground or carried to the area by wind and water flow germinate and grow. The forest is reestablished in due course according to a succession of plant species that is characteristic of that geographic area.

In managed reforestation, people attempt to reestablish forests. However, managed reforestation can give rise to debate over whether the re-established forest has as much biodiversity as the original forest or a forest that has been naturally reestablished. For example, some forests have been replanted with just a single-tree species, while other tree types are prevented from growing back, giving rise to a forest monoculture that resembles agriculture. Increasingly, reforestation is accomplished by planting seedlings from multiple species native to the area. In clear-cut areas, the natural regeneration of a range of plant and animal species can occur. Thus, in some managed reforestation projects, areas of mature or climax forests in which one species or a natural monoculture predominates, areas of the forest are clear-cut or burned, and the deforested areas are naturally reforested. This results in a more diverse ecosystem than previously existed in the natural climax forest. This procedure is particularly beneficial for old forests on preserved public lands, which have often been protected from the renewing influence of forest fires for many years.
