Branch diameter distributions changed from an abundance of small-diameter branches in the upper-crown, and in the middle-crown, composed with differential branch diameter, but only a few large-diameter branches in the lower-crown. Branch volume generally increased from upper- to lower-crown, and reached a maximum around the crown base. Branch density decreased from upper- to lower-crown.
