Did you ever look at a towering, perfectly-straight utility pole and wonder what tree could have made such a large pole? Some of them come from Rayonier land! Our foresters explain how they find, measure and prepare these valuable trees.
LUFKIN, Texas—Did you ever look at a towering, perfectly-straight utility pole and wonder what tree could have made such a large pole?
Some of them come from Rayonier land!
The most valuable trees on our land in the U.S. South, “pole” trees can be used either as utility poles for telephone and power lines or as piles for docks and piers.
Pine trees in a natural forest typically do not provide a large number of poles, explains Rayonier’s Lufkin-based senior timber marketing manager, Jeremy Flood. But our in-house genetic research team has worked to develop seed families that produce tall, straight trees with smaller branches.
“It starts with genetics,” Jeremy says, “followed by decades of management with proper thinning and fertilization. The result is mature plantations with high quality grade timber.”
Finding the Right Trees for Poles
Even though the trees in a stand of timber are the same age and species, they still mature to a variety of shapes and sizes. A forest manager is responsible to ensure that each tree is used for its highest potential. Trees worthy of becoming poles are the rarest—and, consequently, the most valuable—because of the very specific requirements that must be met in order to qualify.
Without careful planning and attention to detail, these valuable trees could easily be missed, and thus sold as sawtimber, a significantly less valuable product. Jeremy’s team created a plan to ensure as many trees as possible became poles.
“These stands have been nurtured and grown for more than 25 years. It would be a waste to not capture their full potential,” says timber marketing manager Shane Bergman, who spearheaded the project.
To locate potential poles before a harvest, a forest technician takes an inventory, statistically measuring the stand of trees to locate those that meet the size specifications needed for poles. Our foresters work closely with a logging contractor, who cuts them down, separates them from the other trees, and places them to the side for the next step.
Strict Specifications for a Tree to Become a Pole
Once the poles are laying side-by-side in a giant row, a forester inspects them one-by-one, measuring them to ensure they’re straight, have an even thickness and are free of defects like scars and knots that could penetrate the wood. They also have to be the right diameter for the customer’s needs.
“Poles have very tight specifications required by the customer and consumer,” Jeremy explains. “It’s not all cosmetic, much of the specs are required for engineering purposes, to ensure strength and longevity.”
Trees that don’t meet the rigorous standards are “culled,” or rejected, and used for sawtimber. Trees that meet the standards are manually cut with a chainsaw to the exact size specifications of the buyer.
The trees are then delivered to a pole mill, where they’re processed and turned into the final product.
Shane couldn’t be happier with the way the project worked out.
“It’s exciting to scale poles because of the relationships you build,” he says. “As you work with the contractors you get to learn about them and see that they have the same values as Rayonier when it comes to being a good steward of the forest. We truly get to work with some great individuals.”
