# 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, 2006b]]). 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 ([[ | # 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?
