Specific gravity and estimated physical properties of Emory oak in southeastern Arizona

Average specific gravity of Emory oak (Quercus emoryi) estimated from 115 increment cores was 0.567 ± 0.011 (95 percent confidence interval). Increment core specific gravity is a predictor of average tree specific gravity. Diameter breast height (dbh) and diameter root collar (drc) were correlated with increment core specific gravity, but the correlations were too low to be valuable for predictive purposes. Estimated physical properties of Emory oak wood were lower than those reported for Gambel oak (Quercus gambelii) but higher than those reported for alligator juniper (Juniperus deppeana)
