A large tamarind tree in south Kolkata with great historical value is safe now. Activists started a campaign to save the tree after builders planned to cut it down. The tree, planted 70 years ago by revolutionary Parul Mukherjee, is home to many birds. The movement began in July 2024 and grew stronger after other neighborhood trees were felled. Activists gathered over 4,000 signatures in a petition by December 2025. On December 30, a complaint was sent to the Chief Conservator of Forests. A ranger inspected the tree and assured the activists that it would not be felled. An altar will also be built around the tree. Barnali Das, a mathematics teacher leading the campaign, said, "We are all happy that we succeeded and hope that everybody keeps their promises." Documentary filmmaker Debalina Majumder, who made a film about the tree, said, "The tamarind tree has brought to the fore the resilience of this city and its creative vision." Samata Biswas, a professor involved in the signature drive, added, "The documentary helped build awareness about urban biodiversity. We want to show it to schools to teach that protecting the environment through collective action is possible."
