Definition - What does Reforestation mean?
Reforestation refers to the replanting of trees on land that has previously had trees, but where these were cut down recently. This is not to be confused with afforestation, which also refers to the planting or replanting of trees, however it refers to the planting of trees in an area where trees have not recently been cut down. The principle difference between the two definitions is time.
Safeopedia explains Reforestation
The goals of both afforestation and reforestation are the same: to avoid deforestation on a large scale and thus stop the large scale depletion of natural resources, preserve the smooth running of our eco system, and biodiversity. Reforestation and afforestation also aid in offsetting carbon emissions, the damage done to our ozone layer, and global warming. This is due to the fact that trees play a vital role in our functioning ecosystem, which includes the quality of our atmosphere.
