I've frequently seen aspens (up to 6" caliper) survive with at least 50% of bark removed. This is why it works… For example, in a plant with collateral bundles, each vascular bundle will feature phloem toward the outside of the stem and xylem toward the inside of the stem.

If our transportation system is interrupted (for example, if our heart stops or a major blood vessel is cut), the cells in our body quickly die because they lack the elements, nutrients and water molecules needed to function properly. Trees die if a ring of bark is removed because it will stop water getting from the roots to the leaves.
