The heartwood of eastern redcedar (Juniperus virginiana) frequently contains areas of light-colored wood. This “included sapwood” is considered to be a defect by some manufacturers. In this study, sapwood, included sapwood and heartwood samples from five eastern redcedar trees were exposed to mold fungi or to subterranean termites in a no-choice feeding test. Extractives content was also measured. The extractive content of sapwood and included sapwood were equivalent. Included sapwood showed the same resistance to mold growth as heartwood, which was more mold resistant that the sapwood. Included sapwood, heartwood and sapwood of redcedar all exhibited resistance to termite attack compared with pine wood controls.
