Temporal changes in stem decay and dead and sound wood volumes in the northeastern Canadian boreal forest

Temporal changes in stem decay and dead and sound wood volumes in the northeastern Canadian boreal forest

Illustration of the calibration of the Resistograph and the creation of the algorithm: ( a ) measurements taken from the left to the right of the disc and ( b ) measurements taken from the bottom to the top of the disc. The straight line is the best-fit regression through the drilling resistance profile. The smoothed line in the profile represents the moving average. The shaded bands indicate areas of rot (bands are green in the online version).
