Trees use electrical signals to communicate with each other and respond to stress. The signals travel through the tree's vascular system.
How trees use electrical signals
Respond to stress: When a tree is attacked or wounded, it sends electrical signals that trigger defensive responses.
Communicate with other trees: Trees can send signals to nearby trees to warn them of danger.
Communicate with roots: Root tips send signals to the leaves, and leaves send signals back to the roots.
Examples of tree electrical signals
When a pine tree is cut, it sends out electrical signals and healing compounds.
When a tree's roots find too little water, they send signals to the leaves to close their openings.
When a tree is attacked by pests, it sends carbon compounds to nearby trees.
Other ways trees communicate
Trees can also communicate through mycorrhizal networks, which are underground webs that connect different plant species.
Some plants may emit and detect sounds.
Some plants may sweeten their nectar when they detect a bee's wing beats.
