Trees Can Share Carbon With Neighbors During Drought

When you walk through a forest, it’s easy to think of each tree as a separate individual. Yet under stress—especially drought—there are strong indications that some trees can share resources with neighbors.\n\nThe mechanism often starts underground: contact points between roots and microscopic partners in the soil can redirect nutrients. Carbon moves as sugars, and in critical moments it may flow toward weaker trees.\n\nThe twist is that this isn’t always “kindness”—it can be strategy. If a neighbor survives, it blocks wind, stabilizes soil, and can slow the spread of pests, acting like insurance for the network.\n\nThis changes how we protect forests: not just trees, but connections. In an age of drought, resilience may depend on the invisible relationships below our feet.
