The response of natural ecosystems to an increasing concentration of carbon dioxide in the atmosphere is a key component of analyses of the current and potential impact of global change. Efforts to understand how eastern deciduous forests will be affected by carbon dioxide enrichment of the atmosphere have heretofore been addressed by studying components of the forest system (individual small trees, specific processes), but it is now time to take the critical leap to measuring the integrated response of an intact forest with a focus on stand-level mechanisms.Goal
To understand how the eastern deciduous forest will be affected by CO2 enrichment of the atmosphere, and what are the feedbacks from the forest to the atmosphere. This goal is being approached by measuring the integrated response of an intact forest ecosystem, with a focus on stand-level mechanisms.
A User Facility
The Oak Ridge FACE facility is a user facility operated by the Environmental Sciences Division of the Oak Ridge National Laboratory (ORNL). It is open to researchers from universities and other research laboratories who are interested in pursuing other questions relevant to forest response to elevated CO2. There are no fees charged for using this facility. However, all research conducted at the site must be approved by the Principal Investigator, and users must agree to abide by the saftey and access requirements of ORNL and DOE. Contact Rich Norby for more information about using this facility.
The facility was established with support from the ORNL Director's R&D Fund and the Biological and Environmental Research program of the U. S. Department of Energy Office of Science. Additional support was provided by the Terrestrial Ecology and Global Change (TECO) program through the National Science Foundation.
