Interpretive Summary: Currently operating open air experiments for investigating the response of forests to elevated carbon dioxide concentrations are being phased out. Therefore, it is time to define the scientific goals and priorities for future experiments. This paper suggests the most important scientific questions to be addressed in future experiments, the types of forest ecosystems for study, and how predictions of the effects of climate change on forest systems can be improved. This article might be used by funding agencies to prioritize areas for future funding.

Technical Abstract: Current forest Free Air CO2 Enrichment (FACE) experiments are reaching completion. It is the time to define the scientific goals and priorities of future experimental facilities. The overarching issues are three-fold: first, which are the most urgent scientific questions and which technological aspects could allow answering those questions. Second, what types of forest ecosystems should be investigated? Third, how can predictions of the effects of climate change be improved by combining elevated CO2 with other climate change factors? As trees constitute both plantations and natural forests with sometimes conflicting needs for high productivity and environmental protection we urge an assessment of elevated CO2 effects from different perspectives taking into account the main functions and constraints of the various forest ecosystems.
