3. Solve equation (5) using the set of coefficients from the column of table 5 

 for the applicable habitat type, and using the first coefficient for the appropriate 

 species : 



ln(Aff) = oi + o 2 ln(A£> + 0.05) + o 3 ln(D .) + o h ln(H/) 



Aff = exp(ln(Aff) + 0.09265) (feet) 



4. Convert growth estimates to diameter and height 1 year hence: 



D. , = /D .' l + BKR*DDS/ 10 

 ^+l ^ 



#. , = ff. + Aff/10 



where BKR = {D^/d^) 2 is the square of the ratio of d.b.h. to diameter inside bark at 

 breast height. 



A computer subroutine prepared in FORTRAN IV to carry out this sequence of calcul 

 tions is given in the appendix. 



If growth for an arbitrary interval (y) greater than 1 year is desired, then the 

 division by 10 in the last two equations would be replaced by multiplication by the 

 value of y/lQ. That is, 



D.. = SD. 2 + BKR* DDS*y/ 10 

 z+y ^ y 



H . = H. * LH*y/\0
