At the end of the 2007 Fiscal Year, the Experimental Forests and Ranges (EFR) Synthesis Network Committee awarded funds to 18 sites to establish a strategic ICP Level II (described below) synthesis network in the United States. Eleven Experimental Forest were selected to be included in the network, as well as seven Long Term Ecological Research (LTER) sites. This will give the USFS R&D a ICP Level II Network starting this year, the only one in North America (see Appendix). Each site will include a NADP weather station, UV Radiation Monitors and Ozone Sensors. The Sierra Ancha Experimental Forest (EF) was chosen to be part of this network, because it is the most southern EF in the contiguous US and because it is downwind from Phoenix, Arizona, one of the nation's largest metropolitan areas.
