Globally, according to FRA 2000, planted forests accounted for only 5% of forest area, but up to 35% of industrial roundwood supply. This is anticipated to rise to 40-44% by 2020. Planted forests reflect a higher social, environmental and economic importance than their area would suggest. Many countries have existing planted forest data that is not based upon forest inventory, is incomplete and often outdated. Thus it is difficult to measure and plan the quantity and quality of planted forest resources and the provision of goods and services that they supply.
