Prevention Methods And the Southern Pine Beetle

Much of today's southern pine forest resulted from natural seeding and planting on abandoned agricultural lands from 1930 through 1950. Young stands grew rapidly with little or no tending. Insect problems developed and intensified as stands became crowded and vigor declined. Silviculture offers the most promising and long-lasting means of reversing this trend.  Studies in the mountains of Georgia, North Carolina, South Carolina, and Tennessee have shown that stands severely attacked by the southern pine beetle were densely stocked, slow growing, and had a large proportion of overmature pine sawtimber.

Silvicultural prevention methods can be broken down into three categories:

1)Spacing: The distance between planted pine trees and tree rows.

2)Thinning: The mechanical removal of rows or individual trees to reduce overall stocking in the stand.

3)Harvesting: The mechanical removal of trees from the site.

If these three preventative measures are taken, landowners will gain some advantage over beetle attack.

If you have a stand of trees that have been attacked by the Southern Pine Beetle, how do you determine whether to start over or to continue with management of the remaining trees, whether pine or hardwood?  University of Tennessee Extension Associate Larry Tankersley has addressed just that issue in his publication on stand determination.
