A wildlife photographer has documented the rare phenomenon of bioluminescence in the forests of Sahyadri Tiger Reserve, where tiny fungi emit a soft green glow after sunset. The fungi illuminate decaying wood and the forest floor, revealing one of the Western Ghats' lesser-known natural wonders.
Wildlife photographer Amit Mane said, "This remarkable occurrence reflects the reserve's immense conservation value and highlights the ecological importance of intact forest ecosystems. Healthy forests support nutrient cycling, regulate water, and maintain microhabitats that are essential for the survival of countless species."
Explaining the phenomenon, Dr Pandurang Bagam said bioluminescent fungi, commonly known as glowing fungi, emit a faint green light through a natural chemical process called bioluminescence. They are typically found on dead bamboo, decaying tree trunks, exposed roots, fallen branches, and leaf litter. While nearly impossible to spot during the day, they become visible after nightfall and can continue glowing for several days, sometimes up to a week.
"They are best observed in the darkest parts of dense forests, where there is little artificial or moonlight. Although scientists have made significant progress in understanding these fascinating fungi, several aspects of their bioluminescence remain unresolved," Dr Bagam said.
