This field guide supplemental describes the data items to record for Fire Effects and Recovery Study (FERS) plots; it is a supplement to the 2010 Field Instructions for the Annual Inventory of California, Oregon, and Washington (i.e., "2010 PFSL manual"). These plots are pre-selected; data items are required as specified when FIRE PLOT = Y. Additional information is collected on these plots, along with any other required measurements for the plot (e.g., P2 and P3 data). P2 measurements are always done when FIRE PLOT = Y, whether the fire plot is on panel that year or not; P3 measurements are only done if the fire plot is also a P3 plot on panel that year.
