Coastal Afforestation: To protect the lives and properties from successive cyclone and tidal bore in the open coastal region seedlings of mangrove plants have been planted along the coastal region. As a result an attractive forest has developed. Within a short span of time the soil of the areas has changed its quality and has become cultivable. Plants: In coastal afforestation usually Bain and Keora are planted. Bain is planted in the soil containing comparatively high salinity and Keora in the estuary region where saline water mix with river carried fresh water.
