Creator:

Mortzheim, Joseph T.

Abstract:

Crown profile was modeled using a system of equations with three components. The first equation predicts the maximum crown width of an open grown tree based on the tree's diameter at breast height. The second equation modifies maximum crown width to represent the largest width of the crown in stand...
