The work shall be executed following eco-friendly and sustainable forestry practices without the use of any toxic chemical pesticides,\u201d the department said.Citing experts, the TOI <\/span>report had stated that the use of anti-termite treatment is not advisable for ecological restoration of the Ridge, which is the green lungs of the city. They said such a method is recommended for campuses and in gardens, not natural forests.A chapter on the ecological impacts of termites in the book, \u2018Termites and Sustainable Management\u2019, states that tropical termites may consume up to half of the annual litter production. \u201cDuring their feeding and nesting activities, termites improve soil aeration, enhance absorption and storage of water in soils, and facilitate carbon fluxes and storage. These processes are crucial for long-term soil fertility, plant growth and soil formation,\u201d it notes.<\/div>\n
