North Carolina, 2010 forest inventory and analysis factsheet
North Carolina’s first annualized forest survey was completed in 2007 and results were published in e-Science Update SRS–029. There were 5,800 ground based samples distributed across the State. At that time, field measurements were collected on 20 percent (a panel) of these plots annually until all plots were completed. This factsheet is an annualized update of panel data collected in 2007 and updated by reprocessing with 2009 and 2010 data. Currently, the 5,800 samples are being collected on a 15-percent panel annually until all plots are completed. The new data represents 5 years of data, 30 percent of which are new since the last factsheet produced for 2007. The new data results in a “moving” average, and keeps the inventory more up to date than if reported every full cycle of panels (currently 7 years). However, the strongest and most reliable trend information comes from comparing data from two full cycles of completed panels. This factsheet is based on data for 2007, 2009, and 2010 extracted from the FIA Evalidator interface on the SRS FIA Web site on September 13, 2011 at http://apps.fs.fed.us/Evalidator/tmattribute.jsp.
