Merchantable Gross Cubic Foot Volume — Forked Trees 



The equation form for forked tree merchantable gross cubic foot volume is 

 V . = V ^ R ^ 



where 



V ^ = Predicted merchantable gross cubic foot volume of a forked tree 



V = Predicted merchantable gross cubic foot volume of an unforked tree 



r. = Predicted ratio of actual merchantable gross cubic foot volume in a forked 

 ■* tree divided by predicted merchantable cubic foot volume in an unforked tree 

 of same dimensions. 



The sp-NF specific equations for j,, their RMSQR, and the number of observations used 



can be found in table 5. For those who do not feel comfortable using these equations, 

 equations that predict R^ ^ as a function of top diameter alone can also be found in 



table 5. Methodological details can be found in appendix IV.
