This method has been modified from the Fuel Moisture Sampling in Boreal Forest Duff manual (by Brenda Wilmore) for field use. For more information on volumetric or TDR (time domain reflectometry) probe sampling procedures, please refer to the full sampling manual. The destructive sampling technique described below is designed to help you quickly collect, measure, and process duff moisture samples in order to calculate percent moisture content and the CFFDRS Fuel Moisture Codes (i.e., FFMC, DMC and DC). This technique is gravimetric, meaning that the moisture content is calculated by weight as opposed to volumetric, where moisture is calculated by volume. An equipment list is provided on page 6.
