IUFRO Spotlight #29
The initiative for establishing Supersites for forest research is only a few years old.
In these supersites, sophisticated, state-of-the-art instruments are used and a multitude of factors in the ecosystem is to be measured to obtain baseline data. As examples: spectrometers will measure how trees absorb and scatter light; laser scanners will map the forest’s three-dimensional structure; soil, plant and atmospheric sciences will be integrated; and mechanistic and policy-oriented modeling will be part of the concept.
Currently operated forest research sites may be integrated in the Supersite network upon upgrading of instrumentation. Eventually, a worldwide network where relevant ecosystem components can be simultaneously monitored and manipulated will be created, including research sites to be newly established, in particular, in the tropics and subtropics.
The information and knowledge gained from the Supersite network will be transferred to other forest researchers and managers to help them understand how forests affect, and are affected by, climate and how to take appropriate steps to mitigate hazards and to capitalize on opportunities.
The editors of the publication on Climate Change, Air Pollution and Global Challenges, see supersites as an effective and rewarding way to ensure that complex links between air pollution and climate change and their joint impacts on forests can be studied, understood and used for mitigation of human impacts.
In terms of forest health, the publication’s editors say climate change and air pollution are two sides of the same coin. However, in research terms, air pollution has mostly been treated as a separate issue that affects only regional or local forest decline.
The publication warns that the omission of air pollution in climate change research leaves a significant gap and argues that such an omission creates a major impediment to a comprehensive understanding of both the adaptation capabilities of forest ecosystems when faced with man-made changes and also how to mitigate the effects of those changes.
They draw particular attention to the climate interactions and air pollution impacts in arising “hot spots” in eastern Asia and across the southern hemisphere.
They believe only a new generation of forest research supersites can provide a thorough understanding of the current challenges and how forests can acclimate and cope with them. They also see the global network of these sites stimulating collaboration across continents and hemispheres, which will be essential for meeting the challenges.
The ultimate goal is to gain an unprecedented amount of information about how forests react to climate and air pollution through coordinated forest research activities. This knowledge will then become available to develop best forest management strategies to adapt to changing climate.
For this goal to be achieved, the editors say, decision makers must recognize that the proposed supersite network will answer key questions on interrelated global impacts of air pollution and climate change on forests. They also add that sufficient funding must be ensured to coordinate and operate the network.
In addition to the obvious beneficiaries in the forest community – policy makers, forest managers, scientists, NGOs and other forest stakeholders – the editors believe the major beneficiary will be the global environment and thus, mankind.
The publication was a cooperative effort of IUFRO Research Group 7.01.00 and the EU-funded COST (European Cooperation in Science and Technology) Action FP0903 MAFor (Climate Change and Forest Mitigation and Adaptation in a Polluted Environment).

A 2014 publication, Forest Trees Under Air Pollution as a Factor of Climate Change, offers further information on the same subject. It can be found at: http://link.springer.com/chapter/10.1007/978-94-017-9100-7_7
IUFRO Spotlight is an initiative of the International Union of Forest Research Organizations. Its aim is to introduce, in a timely fashion, significant findings in forest research from IUFRO member organizations and/or involving IUFRO officeholders to a worldwide network of decision makers, policy makers and researchers.
IUFRO will encapsulate, and distribute in plain language, brief, topical and policy-relevant highlights of those findings, along with information on where/how to access the full documents. The IUFRO Spotlight findings will be distributed in a periodic series of emails as well as blog postings.
The findings reported here are submitted by IUFRO Member Organizations. IUFRO is pleased to highlight and circulate these findings to a broad audience but, in doing so, acts only as a conduit. The quality and accuracy of the reports are the responsibility of the member organization and the authors.
Suggestions for reports and findings that could be promoted through IUFRO Spotlight are encouraged. To be considered, reports should be fresh, have policy implications and be applicable to more than one country. If you would like to have a publication highlighted by Spotlight, contact: Gerda Wolfrum, IUFRO Communications Coordinator, wolfrum(at)iufro.org.
The International Union of Forest Research Organizations (IUFRO) is the only worldwide organization devoted to forest research and related sciences. Its members are research institutions, universities, and individual scientists as well as decision-making authorities and other stakeholders with a focus on forests and trees.
