A '''tree plantation, forest plantation''', '''plantation forest''', '''timber plantation''' or '''tree farm''' is a forest planted for high volume production of wood, usually by planting one type of tree as a '''monoculture forest'''. The term ''tree farm'' also is used to refer to [[Plant nursery|tree nurseries]] and [[Christmas tree farm]]s.
'''Plantation forestry''' can produce a high volume of wood in a short period of time. Plantations are grown by state forestry authorities (for example, the [[Forestry Commission]] in Britain) and/or the paper and wood industries and other private landowners (such as [[Weyerhaeuser]], [[Rayonier]] and [[Sierra Pacific Industries]] in the United States or [[Asia Pulp & Paper]] in Indonesia). [[Christmas tree]]s are often grown on plantations, and in southern and southeastern Asia, [[teak]] plantations have recently replaced the natural forest.From last decades we noticed that our tree plantation ratio and cutting tree ratio are not good.

Industrial plantations are actively managed for the commercial production of forest products. Industrial plantations are usually large-scale. Individual blocks are usually even-aged and often consist of just one or two species. These species can be exotic or indigenous. The plants used for the plantation are often genetically altered for desired traits such as growth and resistance to pests and diseases in general and specific traits, for example in the case of timber species, volumic wood production and stem straightness. [[Forest genetic resources]] are the basis for genetic alteration. Selected individuals grown in [[seed orchard]]s are a good source for seeds to develop adequate planting material.
