Urban green spaces in Indian cities are witnessing a gradual facelift, and Lucknow is leading the way. The Uttar Pradesh capital has introduced a new method to protect trees along footpaths, which has attracted widespread attention online.

Online photo-making tours show trees protected using a grid system. These structures help protect the roots, allow air and water to reach them, and stabilize the surrounding soil. The method appears similar to what is used in many foreign countries.

Sharing the photo on X (formerly Twitter), one user wrote: “This is happening in Lucknow. Great! Someone in the LDA/Municipality has traveled to the EU/Dubai/Thailand!”

More stages to come?

According to X Account, Lucknow Index, which shares updates on various infrastructure developments in the city, these networks are part of the Prime Minister Road project. Phases 1 and 2 were launched in different parts of Mahanagar, Gomtinagar and Hazratganj. The circular also stated that more such phases will be initiated to cover other parts of the city.

Lucknow’s roads are witnessing a massive transformation under the CM Grid Road project

According to the circular, the Prime Minister Road project aims to improve footpaths and upgrade wires, cables and underground pipelines. Fences will be installed throughout the city to protect plants and trees, along with more street lights. Updating the traffic management system is also part of the project.

What people say online

Many users praised the new initiative to protect trees. But at the same time, they also raised concerns about how long the initiative would continue without proper civil responsibility.

“Glad to see this improvement from our Indian cities,” one user commented.

Another added: “Under the CM Grid scheme, efforts are being made in Lucknow to beautify trees along roads in a similar manner to foreign countries. Just let the common people maintain the beauty of the city. Smile, you are in Lucknow.”

“Mera desh badal raha hai (My country is changing),” someone else commented.

“The government should do this at the national level… starting with the states with the highest level of pollution. Low-maintenance evergreen trees should be planted along footpaths at regular intervals. This is a bit expensive, but worth it in the long run,” one person suggested.

“A lot of Kannadigas also travel to the same places, but in Bengaluru we don’t have that kind of shrubs/soil,” another added.

Meanwhile, some also raised concerns about the longevity of the initiative in the absence of common sense, with one writing: “They spit and spoil. We Indians don’t think our country is valuable. We Indians are uneducated, irrational and stupid.”

“People’s civic sense is a bigger problem. Two months from now, you’ll see plastic and other waste at the bottom of the tree,” one commenter noted.

“Love the new tree guards, benches and lights under CM GRIDS! But the question is, how will long-term maintenance and anti-encroachment be ensured so that it doesn’t get damaged/spit on in a few months? Do they have any plans for mechanical cleanup or community involvement?” User X asked.

“Good initiative. But it must be preserved otherwise it may be filled with garbage in no time,” some other reactions said. “The main thing to improve now is civic sense.”

What are the different types of tree protection systems?

Cellular confinement systems (Geogrids): Made from strips of high-density polyethylene (HDPE) that form small cells that stabilize the soil, prevent erosion, and allow water and air to reach the roots. They are mostly installed in driveways, parking lots and high traffic areas.

Metal or Concrete Tree Nets: Made of steel, cast iron, or concrete, these nets are useful in protecting the trunk of a car. At the same time, it also provides a flat and safe walking surface. They are often installed in streets, parks and public places.

Mulch rings: These rings are made of organic mulch such as wood chips or bark. They help conserve soil moisture, insulate roots, and improve soil quality. They are often seen in parks and residential areas.

Plastic or metal: which tree nets are better?

• Durability: Metal grilles are durable but can rust over time, while plastic grilles resist sun and moisture and last longer.
• Cost and setup: Metal is heavy, expensive, and requires several people to install, while plastic is lighter, cheaper, and easier to place.
• Maintenance: Metal grilles need regular painting and repairs. Plastic grilles, on the other hand, require almost no maintenance.
• Security: Metal grilles can be stolen for scrap. This is why plastic grilles are often installed because they have no resale value.
• Environment: Plastic nets are recyclable and have a lower carbon footprint, while metal production generates more emissions.

Where in the world do cities use tree networks?

• United States: Cities like Seattle and New York protect street trees with netting in sidewalks and transit areas.
• Canada: The cities of Vancouver, Winnipeg and Abbotsford have installed networks.
• Australia: Cities use products like Invisigrate to protect trees.
• Singapore: Reinforced stone grids protect trees from heavy urban traffic.
• Europe and Latin America: Cities in France, Spain, Mexico and Brazil are also adopting tree nets.

Why are tree networks important?

• Protects roots from damage and soil compaction.
• Improves soil aeration and water permeability
• Creates a flat and safe walking surface for pedestrians.
• Enhances urban aesthetics and defines tree spaces.
• Some geogrids can support vehicular traffic without harming the tree.

What are the basic measures to remember while installing it?

• Make sure water and air pass through the system.
• The openings should allow for future tree growth.
• Use durable, weather-resistant materials such as HDPE or painted metal.
