Beetle-Killed Lodgepole Pines Are Suitable for Powerpoles

Of 30.8 dead, standing pole-size lodgepole pines per acre in southeastern Idaho, 38 percent yielded 35-40-foot long poles that met ANSI standards for size and form. Decay prevented the utilization of 12 percent of the trees for poles. Basal decay, responsible for rejecting over 50 percent of the trees, usually. could be eliminated by long-butting trees from 4 to 8 feet. Trees dead for 3 years or longer attained an equilibrium moisture content of about 30 percent at one foot, and 14 percent at 16 feet and higher above the ground.
