How this is not a big deal is crazy to me:
Tonka bean trees survive lightning strikes — and use the powerful electric shocks to kill their competitors.
Researchers observed that Dipteryx oleifera—also called the tonka bean tree—in Panama's Barro Colorado natural area not only survives direct lightning strikes but appears to exploit them to eliminate competitors and parasites

Lightning is usually seen as a harbinger of destruction in forests, killing or damaging trees in their blasts. But in the lowland rainforests of Panama, one species of towering tropical tree may have evolved to use this force of nature to its advantage.
The tonka bean tree (Dipteryx oleifera) may actually benefit from being struck by lightning, according to a new study.
Scientists discovered that these trees not only survive these electrical encounters unscathed, but the lightning damages its competitors and the parasitic vines that cling to the tonka bean trees. The researchers published their findings March 26 in the journal New Phytologist.
Researchers tracked lightning strikes over a decade in Panama’s Barro Colorado forest and found that Dipteryx oleifera trees not only survive direct hits but actually use lightning to eliminate vines and nearby competitors—on average removing 78% of parasitic vines and ~2.4 tons of surrounding biomass per strike. Their tall structure funnels lightning off themselves and into others, boosting seed production approximately 14‑fold over their lifetime.
Takeaway: This is the first documented example of a plant species evolving to benefit from lightning, significantly influencing forest competition and ecological dynamics—especially as lightning becomes more frequent with climate change.
