🌳 Nathan’s Nature Notes
Did you know trees never truly heal from an injury?
Instead, they compartmentalize.
When a limb breaks or a tree is otherwise damaged, it quickly goes to work isolating the injured tissue. Natural barriers form within the wood to help keep fungi, decay and other threats from spreading into healthy areas.
Over the next several growing seasons, new wood gradually grows around the injury, sealing the damaged area inside.
And you can see the evidence right here at Dyer. 👀
These trees are carrying the marks of injuries from years past, with new growth forming around the damaged areas. The wounds haven’t disappeared — the trees have simply continued growing around them.
It’s an incredible defense system that can help trees survive for decades or even centuries, quietly carrying pieces of their history within their trunks.
Another fascinating fact from Dyer Facilities Manager and arborist in training Nathan Griffin!
