Longleaf Cone Production Doubled by Ringing

Ringing or partial girdling has more than doubled cone and seed production on some second-growth longleaf trees near Alexandria, La. Since this treatment is easy to apply, it may be useful in the management of seed-producing areas or as an aid in securing natural regeneration on areas lacking adequate seed trees. The study, started in the summer of 1952, was made with open-grown trees ranging from 6 to 12 inches d.b.h, and grouped into 2-inch diameter classes. Ringing was done by cutting two half circles through the cambium on opposite sides of the bole slightly above stump height (fig. 1). The half circles were spaced about 4 inches apart and overlapped 1 inch on each end. Incisions were 1 inch wide and were made quickly with a bark hack of a kind used in turpentining. Once the men became accustomed to the hack, the ringing progressed very fast.
