The figrues are, for the most part, a summation of pure guesses by field personnel who have been provided with little or no training or guidelines. These gross erors will continue until studies provide reliable guidelines for filed personnel to follow. This paper presents a procedure for accurately remeasuring broadcast burned forest residues. Reliable burn data can provide the following benefits: ...'
