Six series of photographs display forest residue loading levels, by size classes, for areas of timber type and cutting practice. Information with each photo includes measured weights, volumes and other residue data, information about the timber stand and harvest or thinning actions and fuel ratings. These photo series provide fast and easy-to-use means for quantifying and describing existing and expected residues.

Four series of color photographs show different levels of downed woody material resulting from natural processes in four forest cover types in Montana. Each photo is supplemented by fuel inventory data and potential fire behavior ratings.
