Afforestation

n. act of turning bare land into forest

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. The term may also be applied to the legal conversion of land into the status of royal forest.Since the industrial revolution many countries have experienced centuries of deforestation, and governments and Non-governmental organisations (NGO's) directly engage in programs of afforestation to provide the benefits of a forest.The term reforestation generally refers to the reestablishment of the forest shortly after its removal, for example from a timber harvest
