An overview of the Sierra Ancha Experimental Forest's role in the free-air CO2 enrichment large wood decomposition experiment
The Duke University FACE facility is located near Chapel Hill, in Orange County, North Carolina on the eastern edge of the North Carolina piedmont. The initial prototype plot was established in June, 1994 and eleven additional treatment plots were activated in August 1996 and operated until October, 2010. To date, 263 publications have reported on results from the experiment. CO2 enrichment was discontinued in October 2010 and the final harvest began. Trees for the decomposition study were harvested in early 2011. Later that year, the logs of three diameter classes representing different positions of the bole were sent to cooperators in the Southern Research Station, Northern Research Station, Rocky Mountain Research Station, Pacific Southwest Research Station, and the Pacific Northwest Research Station to be incubated on site for the Face Wood Decomposition Experiment.
