I'm not talking about deforestation and this is a little different than reforestation which uses "native trees to restock already existing depleted forests.

Afforestation is "the process of establishing a forest on land that is not a forest, or has not been a forest for a long time by planting trees or their seeds." For example, India launched a national afforestation plan for 15 million acres in 2007. The European Union has paid farmers for afforestation since 1990, "offering grants to turn farmland back into forest and payments for the management of forest. Between 1993 and 1997, EU afforestation policies made possible the re-forestation of over 5,000 square kilometers of land. A second program, running between 2000 and 2006, afforested in excess of 1000 square kilometers of land. A third such program began in 2007."
