In news– The fishbone channel plantation method is being implemented in Odisha’s Bhitarkanika wetlands to revive mangroves.
What is Fishbone channel plantation technique?
- It is used to artificially inundate areas that do not get regular tidal inundation. By flooding dried-up wetlands near the intertidal zones, new mangroves can be reforested.
- In this model, the water from a creek is diverted to the targeted site through feeder and field channels, converting the barren land with high saline content into fertile land that supports the survival of mangrove plant species.
- The shape of the fishbone allows the water to reach every nook and corner of the field channels
- The seeds of the mangrove plant species are sown on the banks of all the channels once the salinity is reduced to the required level for the survival of the plants.
- Restoring the cover through the model demands a mix of expertise in understanding tides, sea water parameters, irrigation and botany.
- The fishbone channel plantation technique also helped revive the mangrove cover in the Krishna Wildlife Sanctuary in Andhra Pradesh.
