Abstract: The revegetation program that can be used for slope protection and erosion control is considered as a long-term solution for land reclamation. Revegetation helps in restoring the productivity of soil by reducing soil erosion and protecting soil from further degradation during land reclamation. There are several approaches to revegetation, such as coir matting, plantation of lemon grass, vetiver grass and local (host) plants, which may be used effectively to stabilise iron ore mines dumps. The plantation of local plants through the Miyawaki method has been found more effective than the conventional methods of plantation. This method involves plantation of a number of local (host) plants, such as Karanj (Ponganna Pinnata), Shisham (Dalbergia Sissoo), Neem (Azadirachta India), Sal (Shorea Robusta), Kendu (Diospyros Melanoxylon), Amla (Phyllanthus Emblical) Jamun (Syzgium Cumini), Banyan (Ficus Benghalensis) and Krishnachura (Delonix Regia), closely spaced in a dump slope or small pit.

Keywords: revegetation; lemon grass; coir mat; vetiver grass; local species; selection of plant species; Miyawaki method.
