Modelling of forests and forest management is an integral part of the IMAGE 3.0 framework, with a simulated forest area in 2010 at about 46 million km2 , somewhat larger than observed by FAO as this area includes fractions of other wooded land (see Component [[Carbon cycle and natural vegetation]]). To manage these forests, three forest management systems are defined in IMAGE 3.0 in a simplification of the range of management systems implemented worldwide ([[Carle and Holmgren, 2008]]; [[Arets et al., 2011]]). | Modelling of forests and forest management is an integral part of the IMAGE 3.0 framework, with a simulated forest area in 2010 at about 46 million km2 , somewhat larger than observed by FAO as this area includes fractions of other wooded land (see Component [[Carbon cycle and natural vegetation]]).

# The third forest management system considered in IMAGE 3.0 is forest plantations, such as hardwood tree plantations in the tropics, and poplar plantations in temperate regions. Selected tree species, either endemic or exotic to the area, are planted and managed intensively, for example through pest control, irrigation and fertiliser use, to maximise production. Forest plantations generally have a high productivity level ([[FAO, 2006]]). By producing more wood products on less land, plantations may contribute to more sustainable forest management by reducing pressure on natural forests ([[Carle and Holmgren, 2008]]; [[Alkemade et al., 2009]]). However, the ecological value of biodiversity in many forest plantations is relatively low ([[Hartman et al., 2010]] ). | # The third forest management system considered in IMAGE 3.0 is forest plantations, such as hardwood tree plantations in the tropics, and poplar plantations in temperate regions.

Key policy issues
- How can management influence forest capacity to meet future demand for wood and other ecosystem services?
- What are the implications of forest management for pristine and managed forest areas, and on biomass and carbon stocks and fluxes of relevance for climate policy?
- What are the prospects for more sustainable forest management and the role of production in dedicated forest plantations?
