Simple and Inexpensive Method for Extracting Wood Density Samples From Tropical Hardwoods
A method for extracting wood density samples from living trees with high-density wood is described. A carpenter's auger is used to extract wood chips from a hole of known dimensions. The chips are dried and weighed, and the standard formula — ovendry weight divided by green volume — is used to calculate density. For illustrative purposes, a comparison is made with a water immersion method for samples collected from four tree species with woods of varying densities. The auger method, if used correctly, appears to yield an accurate measurement of wood density. Moreover, it is rapid, simple to use, and employs very inexpensive equipment.
