MUMBAI: Six years after the Bombay High Court ordered a stop to the destruction of mangroves, Mumbai and its neighbouring areas now boast of more than 5,800 hectares of mangrove land designated as protected forests. According to environmental activists , even by conservative estimates, the move has ensured more than 2,500 hectares of open green space in the city and its suburbs. The state forest department recently set up a special mangrove cell to oversee their protection on Maharashtra's coasts.
