— MSR indicates mean square residuals. For logarithmic functions, MSR was calculated 

 as Z(P-0)^/df, where P and are predicted and observed values transformed to arithmetic 

 units and df is the residual degrees of freedom. 



2/ 



— Range m d b.h. for sample trees. 

 3/ 



— Corrections for logarithmic transformation bias were omitted because they contrib- 

 uted more bias than they eliminated. Distributions apparently deviate considerably from log 

 normal . 



4 / 



— This species retains little dead branchwood. For sample trees >4 inches d.b.h., 

 dead weights ranged from 0.1 to 5.1 lb and averaged 1.1 lb. 



— ^ The equation for LP was from a free-hand curve through data that were insufficient 

 for regression analysis.
