Sweetgum growing in 50 natural stands in Alabama were the basis for volume 

 tables 27-54 and 27-55, which are derived from the following equations (Lyle 

 1973): 



Vob 

 Vib 



where 



0.00227205 D^H 

 0.00228576 D^H 

 Sy.x = ^ni(i 



R2 = 0.997 

 0.03039457 



Sy.x = 0.8239 

 R2 = 0.996

Vob = volume outside bark, cu ft 



Vib = volume inside bark, cu ft 

 D = diameter at breast height, inches 

 H = total tree height, excluding 0.5 ft stump, feet
