[The Woodman]

Depends how the ringbarking was done in my experience. Sometimes small portions of cambium remain viable if done with a chainsaw on a larger specimens. The very act of repositioning feet during the process with the saw can make the operator miss the cut into the wood.

Sycs are tenacious and will continue to grow with the slimmest of cambium, just see how this works with spring/summerGrey Squirrel bark stripping.

There's nothing as satisfying as laying into a Syc with a lightweight axe and brushing neat Glyphosate into the cuts.
