Alright, stupid question. What does DBH mean exactly when referring to tree sizes? Diameter breast height? Diameter butt height. Just wanted to know for sure.... Stop laughing.
Uhh huh huh a huh huh he said breast shut up bevis
Better to ask then go around ignorant.
Diameter at Breast height. That is defined as 4.5' off of the ground on the uphill side of the tree.
It may vary from jurisdiction to jurisdiction but in BC it is defined as 4.5' or 1.3 m above the point of germination. This is a delicate point because in BC, timber cruising defines the stumpage rate of timber paid to the Crown (government) for timber cut on provincial land (95% of the provincial cut), and DBH is an important cruising measurement.
I am unclear what the 'point of germination' is, never heared the term before, is it where the roots enter the ground? Just curious as to how that is determined in different species, like a big cedar with flair, or a big ol' maple with exposed high roots? I'm sure there are more than a few variables, is there a rule of thumb for this?
