Trees secretly talk to each other underground. They’re passing information and resources to and from each other through a network of mycorrhizal fungi—mykós means fungus and riza means root in Greek—a mat of long, thin filaments that connect an estimated 90% of land plants. Scientists call the fungi the Wood Wide Web because ‘adult’ trees can share sugars to younger trees, sick trees can send their remaining resources back into the network for others, and they can communicate with each other about dangers like insect infestations.
