RESEARCH SUMMARY 



Presents tables and equations for estimatir^ total cubic volumes 

 •of wood, wood residue, and bark for ponderosa pine, lodgepole pine, 

 western larch, and Douglas-fir. Tables represent second-growth 

 trees 80 years old or less, ranging in size from 1-1/2 inches d.b.h. 

 to the maximum diameter measured for the respective species. The 

 equations and tables provide a means for estimating wood and bark 

 residue volumes from tops, bole sections, and smaller submerchant- 

 able stems. Tables and equations can also be used to estimate total 

 cubic volume for the size classes, species, and locale sampled.
