Description: A method is proposed for estimating the weight of fuel burned (available fuel) by prescribed fires in southern pine stands. Weights of available fuel in litter alone and in litter plus understory materials can be estimated. Prediction equations were developed by regression analysis of data from a variety of locations and stand conditions. They are most reliable for slash pine fuel types but should also provide close approximations for longleaf and loblolly pine types. Information needed to make estimates includes: stand basal area, time since last disturbance (age of rough), and understory height. With these data, total litter layer dry weight and total understory dry weight can be estimated. Total litter layer moisture content is also needed and can be estimated by a procedure described here. Estimates of available fuel have standard errors of about ± 1.0 ton per acre. However, the accuracy of the method depends on the accuracy of input data. Points of weakness and possible misuse of tables are discussed.
