Disease leaves its mark inside horse chestnut

This is the phenomenon uncovered when a 200-year-old horse chestnut tree was felled.

Tree surgeons were stunned when they found the image of a tiny tree imprinted on a fallen branch.



Experts say the bizarre shape has occurred because the heart wood is riddled with rot, which is why it has been chopped down.

Just like a stick of rock, the image of the brown tree can be found imprinted throughout the branch and trunk of the chestnut.
