How Do Trees Protect Themselves From Wounds And Injury?:
Trees that are injured and infected begin a "processes of boundary formation" and new cell growth starts. Trees do not restore or heal the old and dead wood, but instead grows new cells around infected and dead wood - seals disease off. This is called tree compartmentalization where good wood is safely separated from infected wood.
Why Do Trees Live So Long?:
Actually, it is a rare tree that can make it into the upper canopy cover. Many trees lose out before they can make it to maturity. Those that make it have developed an uncanny ability to grow over the many wounds it receives through the years and can live for centuries, depending on the genetics of the species.
How Do Trees Support Themselves For So Long?:
Trees use energy so efficiently that very little waste occurs. Wood is stored energy in the form of cellulose or long strands of glucose that is essentially sugar. This wood is always being created and used in both the living and dead form for structural support and transporting nutrients, sugar and water.
What Is CODIT?:
Instead of "healing" like our skin, an injury to a tree trunk results in surrounding cells changing themselves chemically and physically to prevent the spread of decay. New cells are produced by cells lining the cut area to cover and seal the injured area. Instead of trees healing, trees actually seal.
