This handbook provides procedures for inventorying downed woody material, including methods to estimate weights, volumes, and depths of fuel and duff. It outlines the planar intersect technique, which involves counting intersections of woody pieces with vertical sampling planes to estimate volume and weight. The method is nondestructive and efficient, suitable for both naturally fallen debris and slash. The handbook details field procedures for locating sample points, measuring diameters, and determining depths of fuel and duff. It also includes calculations for converting intersections into tons per acre, using specific gravity estimates and correction factors for slope and nonhorizontal angles. The handbook is applicable to various forest types and includes appendices with sampling intensities, specific gravities of sound material, and methods for calculating needle quantities. The procedures are designed to help land managers practice fuel management, plan for prescribed fire, and estimate utilization potential. The handbook emphasizes the importance of accurate sampling and measurement to provide an objective basis for managing debris and assessing fire hazards.This handbook provides procedures for inventorying downed woody material, including methods to estimate weights, volumes, and depths of fuel and duff.
