A key element of developing biomass utilization technology is an understanding of basic ecological processes. The amount of biomass available in a tree was explored in a 1983 study (Sirois 1983). This publication documented not only the above ground biomass availability, but also the below ground biomass for several species of southern hardwoods. Prediction equations for estimating green and oven-dry biomass were developed and presented for sweetgum, hickory, southern red oak, and white oak. Biomass tables were presented for each species tested using d.b.h. and height to estimate the green weight of a tree (stem, branches, stump, and roots). This paper provides detailed methodologies employed to derive these equations and tables.
Additional equations were developed (Franchi
and others 1984) to predict
the dry weight of biomass in understory stems in the
