Insects and Damage

The 1936 Tillamook Burn (Oregon) killed a vast amount of Douglas-fir and western hemlock, much of it old growth. To aid salvage logging, R.L. Furniss investigated the rate at which several wood-boring insect species degraded the dead trees. He also took photos of the logging operation. At that time, trucks had just replaced trains for transporting logs but trees were still being felled by ax and crosscut saw. Here Bob Furniss examines a butt log displaying early stage of mining by a cerambycid, Asemum striatum (L.). This and other borers eventually riddled sapwood of fire-killed trees but the heartwood remained salvageable for years. Photo F-607 by R. L. Furniss, WFIWC archives.
