FAO uses the current Global Forest Resources Assessment’s (FRA) definitions for forests. A planted forest is defined as a forest that at maturity is predominantly composed of trees established through planting and/or deliberate seeding. Planted forest includes but is not limited to plantation forest. Plantation forest is defined as an intensively managed planted forest that at maturity is composed of one or two species, has one age class, and has regular tree spacing. Forest that is planted for ecosystem restoration or protection and forest that resembles natural forest at stand maturity is not defined as plantation forest, as per the Forest Resources Assessment (FRA) 2020.
