At present, the objectives of forest development are not only for yield sustainability (“Sustained Yield Principle”) but also for ecosystem sustainability (Sustained Forest Management), and it is expected that the forest development creates direct benefits in the form of wood and other forest products, as well as ecological benefits in the form of hydrology, orology and protection services toward natural environment.
 Ecosystems which need to be conserved in the area of forest territory are as follows:
1. Natural ecosystems, in the form of tropical rain forests, monsoon forests, swamp forest, peat swamp forests, heath forests and mangrove forests.
2. Artificial ecosystems in forest territory such as industrial plantation forest and people plantation forest.
    Forest ecosystem also functions as living space and food seeking area for people community around the forest (local people), habitat of various wild animals and plant species, biodiversity conservation medium, germ plasm conservation medium, hydro-orology service, and protection service for nature and environment.
    On the basis of Consensus Forest Land Uses – Provincial Spatial Plan (TGHK – RTRWP) which are integrated in harmonious manner (paduserasi), it can be shown that   size of forest area in Indonesia is 120.35 million ha (61 % of terrestrial land size) which on the basis of their function, the forest territory consist of : Production Forest 58.25 million ha, Convertible Production Forest 8.08 million ha, Protection Forest 33.52 million  ha and Conservation Forest 20.50 million ha.
