Getting Struck by Lightning Actually Helps This Tree Thrive

Some trees don’t just survive lightning – they thrive on it. Scientists studying Panama’s tropical forests have discovered that Dipteryx oleifera trees often benefit from lightning strikes that devastate their neighbors.

These resilient giants lose harmful parasitic vines, gain access to light, and even increase their reproductive success after getting zapped. With lightning strikes becoming more common due to climate change, these trees may have a shockingly bright future.

Lightning Strikes: A Shocking Advantage

Getting hit with millions of volts of electricity might sound deadly, but for some trees, it’s surprisingly beneficial. A new study published today (March 26) in New Phytologist finds that certain tropical tree species not only survive lightning strikes but may actually gain an advantage from them. In fact, researchers suggest these trees could be specially adapted to attract lightning, acting almost like natural lightning rods.

The study was led by Evan Gora, a forest ecologist at the Cary Institute of Ecosystem Studies, who investigates how lightning shapes biodiversity and carbon storage in Panama’s tropical forests.

Discovery of a Resilient Tree

Lightning strikes kill hundreds of millions of trees globally each year. But in 2015, while conducting fieldwork in Panama, Gora and his colleagues noticed something unusual: a Dipteryx oleifera tree that had survived a lightning strike with minimal damage, even though the blast was powerful enough to blow a parasitic vine out of its canopy and kill over a dozen nearby trees.

“Seeing that there are trees that get struck by lightning and they’re fine was just mind-blowing,” Gora recalled. Over time, the team encountered other Dipteryx oleifera trees thriving after getting hit, so they decided to take a closer look.

This narrated video captures the response of a Dipteryx oleifera tree that was directly struck by lightning in Panamanian tropical forest in 2019. The video shows the tree’s condition and the condition of it’s neighbors ~4 weeks after the strike occurred, and then returns nearly 2 years later to show that the lightning strike has killed this tree’s competitors and the lianas (that is, woody vines) infesting its crown. The general trends captured in this video are consistently observed among all directly struck D. oleifera trees – the trees exhibit minimal observable damage, but the lightning strike kills neighboring trees and lianas that compete for light and other resources. In an associated paper, we show that lightning tolerant tree species often exhibit these patterns, and that the cumulative effects of these lightning strikes facilitate the vast majority of seed production (that is, fecundity) for this species.

Clues Point to a Natural Adaptation

Scientists had previously suspected that some trees evolved to tolerate lightning, but evidence to back it up was lacking. In 2022, Gora and colleagues demonstrated for the first time that trees differ in their ability to survive getting hit by lightning. Their new paper, published Wednesday, is the first to show that trees can benefit from these electric jolts.

Using a unique lightning location system, the team tracked the outcomes of 93 trees that had been struck by lightning in Barro Colorado Nature Monument in central Panama. For two to six years after the strike, the team measured tree survival rates, crown and trunk condition, number of parasitic vines or lianas, and neighboring tree mortality. The study included nine directly struck Dipteryx oleifera trees, and compared them with 84 other trees that had been struck.

Dramatic Differences in Tree Survival

All nine Dipteryx trees survived direct lightning strikes with only minor damages. In contrast, directly struck trees of other species were badly damaged, losing 5.7 times more leaves from their crowns, and 64% died within two years.

When each Dipteryx tree was zapped, an average of 9.2 neighboring trees were killed as the electricity traveled between adjoining vines and touching branches, or jumped across small gaps between trees. Lightning strikes also reduced Dipteryx liana infestations by 78%, freeing trees from some of the pressure these parasitic vines have on light and nutrient availability.

Long-Term Patterns and Canopy Clues

These patterns also bore out across the broader population. The team found that Dipteryx trees tend to have fewer lianas. Analyzing trends in tree death over the past 40 years, the researchers found that the trees neighboring Dipteryx trees were 48% more apt to die than other trees in the forest, likely because of lightning.

Using drones, Gora and colleagues created 3D models of canopy height, which showed that Dipteryx trees tend to be about four meters taller than their nearest neighbors, likely because lightning killed their taller neighbors, giving them an advantage in competing for light and space.

Evolutionary Boost from Electric Jolts

“These data provide the first evidence that some trees benefit from being struck by lightning,” the authors write. Or, as Gora puts it, “It’s better off for a Dipteryx oleifera tree to be struck than not.”

Because of all these benefits, Dipteryx oleifera trees may be specially adapted to attract lightning. With their distinctive height and unusually wide crowns, they may be up to 68% more likely to get electrocuted than other trees with average height and crowns, according to the team’s calculations.

Living Long Enough to Get Struck Often

Estimates suggest individual Dipteryx oleifera trees are directly hit by lightning every 56 years, on average. And since the trees can live for hundreds or possibly more than a thousand years, they are expected to survive these blasts many times throughout their lives. During the study, one of the Dipteryx trees was struck twice in just five years.

The remarkable ability to survive lightning strikes and benefit from the removal of lianas and competitors gives Dipteryx trees a major advantage over other trees. According to the scientists’ calculations, lightning tolerance boosts the species’ ability to produce offspring by 14 times.

What’s Next in Lightning Research

Next, the team aims to investigate what electrical or structural traits allow these trees to survive lightning strikes. They would also like to explore whether other species show lightning tolerance, to better understand how common this phenomenon is.

What is clear is that lightning plays an underappreciated role in tree competition. And with lightning on the rise in many regions due to climate change, its influence may increase, potentially favoring lightning-tolerant species like Dipteryx oleifera. Understanding lightning and its role in shaping forests may be important for predicting changes in biodiversity and carbon storage, and for informing tropical reforestation efforts.
