We protest for temples, we stay silent for such trees
Why the Nagalingam / Cannonball Tree- Couroupita guianensis matters.
It’s not "just a pretty tree". It’s ecological, cultural, and climate infrastructure.
The 'Keystone' tree
For biodiversity:
Bat + Bee magnet: Flowers open at night with a strong scent. Pollinated by bats + carpenter bees – both are declining pollinators. No bats = no Nagalingam = less mango pollination nearby.
Bird + Squirrel canteen- Cannonball fruits weigh 2-3kg. When they fall + crack, pulp feeds squirrels, monkeys, birds. One tree = food court for urban wildlife.
Host tree- Supports 15+ species of epiphytes, orchids, ferns on its bark. Old trees = micro-habitats.
For climate:
-Natural AC the canopy = 10-12°C cooler underneath. One mature tree = cooling power of 10 room ACs running 20 hrs/day. Critical for Mumbai heat islands.
Carbon sink- 200-yr old tree stores ∼ 22 tons CO2. New saplings take 40 years to match that.
Air purifier- Large leaves trap PM2.5 + dust. Mumbai needs this more than statues.
Cultural + Religious Importance – "Shiva’s Tree
Shivalinga shape-: Flower has central lingam + hooded snake structure. Known as Nagalingam in South, Kailaspati in North. Offered to Shiva, especially in monsoon.
Temple tree- Planted in 90% of old Shiva temples across India. Ayodhya, Kashi, Rameshwaram – all have them. Cutting it = desecrating the temple ecosystem.
Ayurveda- Bark, leaves, flowers used for cold, skin diseases, anti-microbial. Fruit pulp = antiseptic.
Not for self-medication_ – but biodiversity loss = medicine loss.
Urban Importance – Why India needs it.
Storm survivor- Buttress roots + low center of gravity. Rarely falls in cyclones.
Low maintenance👇Native-adjacent, pest-resistant, no watering needed after 5 years. BMC spends lakhs on exotic trees that die. This one thrives.
Space efficient- Canopy is high + narrow. Doesn’t block signals/balconies like rain trees. Perfect for roadsides.
The Threat – Why it’s disappearing
"No commercial value" Timber isn’t useful, so the forest dept doesn’t replant.
Our grandfather prayed to this flower and our kid will see it only in textbooks
