Trees with defective stems or crowns were selected to uniformly distribute the retained crowns for increased sunlight to the forest floor. Cull the woods like you cull the herd. From stems and crowns of good quality, a variety of species were retained as future "crop trees." Thinning will reduce the basal area to about 65 sq. ft. per acre, with a subsequent harvest retaining about 50 sq. ft. per acre. Initial basal area was about 90 sq. ft. per acre.
