New scientific research suggests that ancient fern savannahs played a significant role in transforming parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction event. This period, known for its dramatic loss of biodiversity, was exacerbated by environmental conditions that favored highly flammable vegetation.
The Fern-Fire Cycle
Fossil evidence indicates that these ancient ferns possessed a unique resilience to fire. Rather than being permanently wiped out, the ferns repeatedly regrew in the wake of blazes. This rapid regeneration created a continuous cycle of fresh fuel, effectively prolonging the devastation across the landscape.
This discovery provides a deeper look into the ecological feedback loops of the Triassic period. The dominance of these fern-rich ecosystems likely contributed to the extreme heat and atmospheric changes that defined one of Earth's most significant extinction intervals.
