Historical information

In the measurement of the diameter of a standing tree, allowance must be made for the depth of the bark if the actual diameter of underlying wood is to be assessed. Used primarily in softwood plantations, the bark gauge provides an alternative to cutting a 'window' into the bark.

The sharp end of the gauge is thrust into the bark until it meets the resistance of solid wood. The depth to the wood is then read from the shaft of the gauge.
