Establishment of forest plantations on temporarily unstocked lands that are considered as forest. (FAO, 2001)

The re-growth of forest after a temporary (<10 years) condition with less than 10% canopy cover due to human-induced or natural perturbations (FAO 2000). (UNEP/CBD/SBSTTA, 2001)

The direct human-induced conversion of non-forested land to forested land through planting, seeding and/or the human-induced promotion of natural seed sources, on land that was forested but that has been converted to non-forested land. For the first commitment period, reforestation activities will be limited to reforestation occurring on those lands that did not contain forest on 31 December 1989. (UNFCCC, 2001)

The re-establishment of trees and understorey plants at a site immediately after the removal of natural forest cover (ITTO, 2002)
