Mumbai Taking the controversy over the Veermata Jijabai Bhosale Udyan a step further, the Brihanmumbai Municipal Corporation (BMC) has said the garden has only 10-12 rare trees. A green activist had said that there are 952 rare trees in the zoo. The BMC has also said it will set up skywalks for nature lovers and botany students to study the trees as the ground area will be inhabited by animals.
