Some biomass data on the components of tree and shrub species were collected nearly every summer from 1963 through 1978 for the express purpose of relating fresh and dry weight to the commonly measured physical dimensions of height and diameter at breast height. Inasmuch as weight of all of the components is a considerable departure from volume of the bole several tabular formats were tried. In the first efforts (Young, Strand and Altenberger 1964; Dyer 1967) tables similar in appearance to regional volume tables were prepared for merchantable size trees of eight species. This was followed (Young and Carpenter 1967) by a downward extension for the same eight species using only height ranging from l-35 feet. Ribe (1973) then prepared tables for the components of the aboveground portion of 12 hardwood species, mostly of the puckerbrush category for diameters ranging from 0.6-6.9" dbh (1.G16.50 cm) in both English and Metric units.
