The 95-percent confidence inter- 

 val for a predicted d.b.h. value v^/ould 

 be approximately y° ± 2v(y°) ^'2. There- 

 fore, the spruce stump measuring 14.0 

 inches in diameter would be expected 

 to have a d.b.h. of 12.1 inches, but its 

 d.b.h. could be as high as 14.1 inches 

 or as \ovj as 10.1 inches at two stan- 

 dard deviations (12.1 ± 2(1.04)''2). 



Once d.b.h. is estimated, tree 

 volume likewise can be estimated. 

 Local volume tables can be used to 

 determine volume from d.b.h. mea- 

 surements, but such tables may be 

 unavailable. Standard volume tables 

 should then be used, but average 

 heights must be taken from trees left 

 standing in the surrounding area 

 because standard volume tables usu- 

 ally require that both d.b.h. and height 

 be known. 



Limitations 



No stump heights were mea- 

 sured, so the equations represent the 

 stump diameter/d.b.h. relationships 

 for average stump heights in the 

 Northeast. USDA Forest Service stan- 

 dards normally assume a 1-foot stump 

 height, but this may vary in actual 

 practice. The equations presented 

 here should be used where trees were 

 harvested by conventional methods 

 close to a 1-foot stump height, or 

 where equations for the desired spe- 

 cies are unavailable. In other situa- 

 tions, equations or tables that include 

 stump height may be more appropriate.
