This work has experimentally proved that hyper salinity, a major cause for degradation of coastal mangrove habitats, can be alleviated by flushing of hyper saline soil with tidal water and/or with rainwater. Over a period of three years after digging the creeks to flush hyper saline soil with tidal water, an appreciable reduction in soil salinity and a moderate increase in colonization of mangroves are observed. Soil analysis showed a significant reduction in salinity after 2 months of storage of rainwater with a significant and concomitant increase of heterotrophic bacterial counts and nutrients. This study raises the possibility of converting degrading mangrove habitats to luxuriant ones through man-made efforts.
