  1. Duke Face Project By the Tree Folk: Brendan McMahon, Andrew Lomax, Helen Zhang, Allen Yang

  2. About the Duke Forest FACE facility The Forest Atmosphere Carbon Transfer and Storage (FACTS-I) facility is in the Blackwood Division of Duke Forest. The facility has 12 FACE rings that monitor elevated atmospheric CO2 concentration , ambient CO2control, elevated soil nutrients and CO2 X soil nutrient enrichment. The system has been running since June 1994 as a prototype plot. In August 1996 three additional plots were started and the remaining plots were partitioned in January 2005. FACE stands for Free-Air-CO2-Enrichment

  3. Experiments done at the FACE facility • Many experiments have been done at this facility on a wide range of topics. These topics include, but are not limited to: forest structure, the forest ecosystem, cycling of material through the forest, forest microbes and forest physiology. The influence of CO2 on these topics is the main focus of their research.

  4. Research Site • Blackwood division of the Duke Forest near Chapel Hill. • Clear-cut/Burned in 1983 • Replanted with Loblolly pines • Mostly clay soil, soil pH, nitrogen, and phosphorus are mid-range for pines. • 90 hectares (220 acres, 0.3 sq mi)

  5. Enrichment • Carbon Dioxide added via tubes • 200 micromoles (millionth of a mole) • Fertilized by hand • Ammonium nitrate

  6. Instruments Mostlu made up of: • Lysimeter • Litter bags/traps • Minirhizotron • TDR sensor • Throughfall trap • Watermark sensor • Tower

  7. Recent Publications • http://www.fao.org/DOCREP/ARTICLE/WFC/XII/0515-B4.HTM • The above is “Using process-based models to estimate forest productivity for management purposes”, their most recent publication(in print now) • Hundreds of different publications, all about trees/forests in some way. • They’ve given hundreds of presentations too.
