400 volunteers dedicated five hours on ‘Earth Day’ to create a forest by 2028

5500 saplings of 96 varieties. 400 volunteers. Five hours. And the result would be a dense forest in Bengaluru, in next 10 years. How did it happen?

On April 22nd, World Earth Day, around 400 volunteers gathered at a Government High School near Bommasandra in Bengaluru, to plant 5500 saplings that will result in a forest by 2028.

This Earth Day plantation drive was organised by Say Trees, a Bengaluru-based NGO that’s actively involved in tree plantations in India. This was their 8th plantation drive using the Miyawaki method of creating a forest, introduced by Akira Miyawaki, a Japanese Botanist. This method includes planting a variety of native species close together in a small pit. The advantage: trees grow 10 times faster and 30 times denser. The objective is to grow a 100-year-old forest in 10 years.

At 7.45 am I walked into the Government School to find organisers arranging the equipment and saplings.

Saplings were placed closely in strategic positions where no two varieties were kept adjacent to one another, to avoid too much density in one area.

Soon after, volunteers along with families and children, arrived. We were then briefed on the Miyawaki method of creating a forest and a demonstration on how to plant a sapling.

It was 8.15 am. We then formed groups of two to three individuals, and started planting. The forest pit had been prepared by Say Trees members 10-15 days prior to the plantation drive where they dug the ground 1 feet deep, added manure and cow dung to enhance microbial activity.

Step-by-step process of planting a sapling

To plant every sapling, we first dig the earth to the height of the sapling bed.

Remove sapling from plastic/ cement bag. Then place it carefully in the dug out pit taking care to keep the soil around the sapling intact, as it has been growing in it for a few months and is accustomed to that soil.

Add a handful of manure in the pit around the sapling.


Fix a stick next to the bed of the sapling and tie it to the sapling. This gives the sapling support as it grows. Then cover the sapling with the dug out soil and press it to keep it firm.

One sapling is now successfully planted!

There were 96 varieties of saplings, including peepal, neem, banyan and other fruit-bearing ones, picked up from multiple nurseries around Bengaluru. In a year’s time, these saplings will grow to be dense, not leaving any space for people to even walk through it. “Planting a variety of trees gives biodiversity to the environment,” adds a Say Trees member.

This is what is looked like at the end of five hard working hours. Hay was added to the pit to keep water intact in the soil. And around noon, the plantation drive came to an end with 5500 saplings successfully planted!

This is the first time ever the Miyawaki method of creating a forest was implemented in a school in Bengaluru. This government school plantation will have permanent manpower and sprinkler irrigation system for maintaining the forest for the next two years. Even if 92-93% of the saplings survive in the next 2-3 years, they would become self-sustainable with rainfall, ground water and water from sewage treatment plants for their nourishment. The organisers are yet to finalise from which sewage treatment plant water will be used.

“Planting saplings is only a tip of the iceberg, maintenance is more important,” says Durgesh Aghari, Head of Partnerships and Projects at SayTrees. They plan to have a pond next to the forest pit where birds and small animals can come eat and find water to drink. The idea is to create a self-sustained space.

Fidelity Investments whose many employees joined the effort funded this drive.

Namita Iyengar, a Computer Science lecturer at Mahesh PU College, came for her first ever plantation drive. She arrived early morning to find the saplings lying around, and left with much joy after helping plant them all. “I plant trees in my house but coming and planting trees for the world, especially on Earth Day feels good,” says Namita.

In last rainy season, Say Trees planted about 1 lakh trees. The survival rate, says Say Trees, has been 80-85% whereas around lakes it is over 90%. Plantations around lakes are safe as there is no threat from cattle, anti social elements, and local goons. Other areas such as railway land and open spaces have lower survival rates due to cattle movement and external human intervention.  For example, a railway land near Yeshwantpur suffered 45% loss of saplings due to illegal dumping.

Another volunteer, Nagaraj Chilale, found out about SayTrees plantation drives a couple of months back and had been waiting for this day ever since. “Everybody was enthusiastic despite the harsh summer heat and committed to reaching the target,” he adds.

At the end of five hours that hot summer morning, I left the government school feeling elated on being an active participant in improving my city’s green cover.

Flamingo deaths in Navi Mumbai: A wake up call

Death of 39 flamingos after colliding with an aeroplane has brought attention to shrinking habitats and consequent risks to migratory birds.

On May 20, 2024, an Emirates airplane, descending to land at Mumbai’s Santacruz airport, collided with a flock of flamingos, causing significant damage to the aircraft and killing 39 flamingos. This incident underscores a critical and often overlooked aspect of aviation safety: the risk of bird strikes. News reports and investigations into the bird strike have revealed two primary causes: The high power lines running through the Thane creek flamingo sanctuary could have been responsible. These power lines, built at great heights, may have forced the flamingos to fly higher than usual, putting them in the path of the descending…

Saving Aarey: An environmentalist’s learnings from a Mumbai movement

In a video, Rishi Agarwal talks about his recently launched book on the Save Aarey movement, which tried hard but failed to get the Metro car shed out.

Two months ago, a report by Global Forest Watch, said that India had lost 2.33 million hectares of tree cover since 2000. Given the push for infrastructure development in the country and closer home in Mumbai, forests such as Aarey, Sanjay Gandhi National Park, and wetlands and mangrove forests in Navi Mumbai are constantly at risk.   While successive governments promise afforestation in other areas as compensation, activists and citizens often find that the biodiversity and fragile ecological balance are lost forever. However, the argument that development at the cost of the environment is unavoidable, seems to be getting stronger. Those…
