Shows the condition as of March 31, each year based on 1995.

The following management plan has been implemented in order to tend to single-storied forests multi-storied forests and naturally generated forests.

When tending to single-stoned forests a certain group of trees are immediately cut in order to create an artificial#1 forest consisting of a unitary crown layer and for maintenance purposes (tended single-storied forest management)

When tending to multi-storied forests management by partially carrying out selective culling of trees#2 in order to create an artificial forest consisting of multiple crown layers#3 (including forests which temporary become single-storied forests in relation to management) and for maintenance purposes (tended multi-storied forest management)

Management of naturally, generated forests mainly involves making the most of natural power for the purpose of creation and maintenance. (Naturally generated forest management) This management includes prohibited felling for conservation of national land. conservation of natural environment and conservation of species.

#1 "Artificial" is general term for tending operations such as planting, assistance in regeneration (such as surface scarification for regeneration with natural species and brush cutting, bud pruning, weeding, salvage online and thinning)

#2 "Selective culling" refers to repealed cutting of mature trees in a forest (selective felling) in a planned manner every few years after several decades.

#3 "Multiple crown layers" are mapped according to variation of tree height due to the difference in tree age and tree species.
