A naturally growing rich mangrove forest along both sides of the railway causeway through the Paravur lake between Mayyanad and Paravur railway stations have been felled. No clear reason has been given for clearing the mangrove forest which stands in a Coastal Regulatory Zone.

The development comes at a time when the Railways have announced being eco-friendly while taking up development projects. Railway land in Kerala has rich mangrove coverage in several areas, especially in the northern parts of the State. The Paravur lake area has thick mangrove forests on railway land.
