Estimating Cone Yield of Shortleaf Pine
The cone production of shortleaf pine (Pinus echinata Mill.) varies from year to year. It is often desirable to estimate cone yield so that timber sales can be scheduled to coincide with cone maturity, or to decide which trees in a seed-production area have enough cones to make collecting worth while. The results of a study in a shortleaf pine seed-production area in the Missouri Ozarks showed that there were actually about three times as many cones on a tree as indicated by a binocular count.
