We conducted a 10-yr study of branch/trunk growth of 400-year-old Dougas-fir trees. 88% of the increment of branch mass per tree occurred in the upper half of the crown. Increments of trunk mass contributed most of the lower-crown mass increment. Growth increments of the crown were not reflected in core samples at lower heights. Large P. menziesii trees can sustain wood mass production, especially in the crown.
