I (and presumably most of this thread's readers) understand that you distinguish scarring
of the cambium from the formation of stripbark.
But the cause of the stripbark growth spurt has more to do with the fact that if there's only a strip
of cambium in use there is no radial component to speak of.
Not exact matches
It's only when it starts to rot that the inner core becomes once again living material fixing more carbon, instead
of a dead structural center around which the thin living
cambium is wrapped.
It's surely not the job
of a climate scientist to work out in a bottom up way what factors are responsible for how much weight a tree puts on each year and how much
of that is allocated to the
cambium and gets converted into a tree ring.
While the strip
of live
cambium does vary in width over time, the corners do not «wrap around» to re approximate a whole bark form.
The radial gradient
of sap velocity in these trees was quantified in an earlier study (Cohen et al. 2008), indicating a quasi-linear decrease from maximum sap velocity at 5 mm below the
cambium down to zero at 40 mm.
