As discussed last week, part of the problem with this white pine is the rotted trunk. It must be addressed by cleaning out the rotted wood, drying it out, and applying a preservative. Here is the rotted section before:
Each species displays unique deadwood traits. JWP tend to have hollows develop, leaving behind a lattice-like scaffolding of former branches. Below is a good example of this tendency. The JWP in this article also shows this lattice-like scaffolding deep inside the trunk. The wood was simply harder than the rotten wood around it, and has persisted. It’s good to study deadwood of different species to gain a good perspective of how it should look.
