What if Trunk Decay is Found?
The extent of the decay column is shown by the multi-elevation scans, and the amount of remaining solid wood (RSW) is shown by both the cross-sectional image and the plot of RSW around the entire circumference for each elevation. If decay is found, the location and extent of the decay pocket, along with the amount of RSW can be used by a certified arborist to determine if the tree has sufficient structural integrity to remaining standing (and be reexamined periodically), or if there is sufficient risk to merit a recommendation for removal. The presence of decay, sometimes even extensive decay, does not necessarily mean the tree needs to be removed.
