As the Delhi High Court hears the dispute over the proposed takeover of the Delhi Gymkhana Club’s land, a new survey has documented 486 mature trees across 51 species — highlighting the ecological value of one of Central Delhi’s largest green spaces.
In June, a HC bench led by Justice Neena Bansal Krishna warned that the city would “suffocate” if heritage green spaces gave way to concrete and underscored the ecological value of preserving the campus. The Land and Development Office (L&DO) has initiated eviction proceedings against the Club, a move that is being challenged before the High Court.
Why only mature trees were counted
The survey was led by naturalist Vijay Dhasmana and environmentalist Dr Roli Shukla Thapar, along with citizen volunteers. The team documented only mature trees with a girth exceeding 50 cm — many of them decades old and individually geotagged for the first time — using field visits, species identification and GPS-based mapping to create a digital inventory.
The focus was on mature trees because, unlike younger trees, they absorb several times more carbon, provide deeper shade, support far greater biodiversity and take decades to replace if lost.
According to the survey team, nearly 100 younger trees, estimated to be 25-40 years old, as well as shrubs and other vegetation, were not included. This means the campus’s total vegetation cover is higher than the documented count.
Common species found
Putranjiva was the most abundant species, with 84 mature trees, followed by Neem (63), Royal Palm (44), Mango (35), Karanj (28), Mulberry or Toot (23) and Peepal (22). The campus also has 15 Jamun trees, 13 Vilayati Keekar, 12 Foxtail Palms and 10 Fishtail Palms.

The survey identified exceptionally large specimens of Baheda, Semal and Holoptelea integrifolia that qualify as heritage trees — exceptionally old, large trees that provide high ecological benefits because of their age, size and expansive canopy.

Delhi has increasingly begun documenting such trees as ecological assets. Earlier this year, the New Delhi Municipal Council (NDMC) identified 33 heritage trees across the Lutyens’ Bungalow Zone.
At the Club, the inventory also recorded several ecologically significant native species that support birds, bats and insects, including Banyan, Peepal, Pilkhan, Goolar, Baheda, Arjun, Bel, Semal, Kachnar, Dhak and Imli.
Among the exotic species documented were African Sausage Tree, Silky Oak, Chinese Fan Palm, Jacaranda, Tabebuia, Plumeria, Moulmein Rosewood and Chir Pine.
A thriving ecosystem
Ecologists associated with the survey said that unlike young plantations, decades-old trees store substantially more carbon, provide extensive canopy cover that cools surrounding areas, support birds, bats and insects, and help intercept rainwater.

These ecosystem services, they said, cannot be recreated for decades if mature trees are lost.

They pointed to how bird species like Black Drongo, Rose-ringed parakeet, Coppersmith barbet, red-vented bulbul and Common myna were found regularly engaging in nesting, seed dispersal and feeding within the campus.
Underscoring the importance of preserving green spaces, Delhi-based environmentalist Bhavreen Khandari said, “We’ve reached a point where every patch of green is seen as a development opportunity. That mindset must change. Open spaces are not idle spaces, they are working every single day for us.”
On the heritage trees, she said these “are natural cooling towers, biodiversity hubs, carbon stores, rainwater managers and silent protectors of public health. They deserve the same respect we give to roads, bridges and hospitals because they are equally essential urban infrastructure.”

Dr Roli Thapar said the exercise changed the perception of those familiar with the campus. “One can see that Gymkhana is a green space, but the survey made one realise this more intently. We geotagged only the ‘big trees’ as part of the survey — there were almost 500 of them. If we counted all the trees, shrubs and plants, the number would be more than ten-fold. This greenery must be preserved.”
