vital role in planting saplings in the tidal wetlands as a purpose of agro forestry
development in the low lying deltaic coast.
Existing mangrove forests in the buffer areas of the Sundarban Reserve Forest
(National Park) need immediate cares and also require the strict implementation of
CRZ rules in the coastal zone to protect and avoid conversion from further human
uses.
11.7 Conclusions
Mangroves are not only degraded in the buffer areas of reserve forest, they also have
been reduced from the inner parts of forests by increased salinity stress around
hypersaline patches.
Through the remote sensing studies it is established that both the density and
health of mangroves are degraded in between 1989 and 2015. Hypersaline patches
are only reduced in the landward sides of mangrove dominated islands after storm
effects and river floods. However, the seaward face of islands is affected by the
growth of such saline blanks at smaller scales. Loss of tidal drainage, reduction in
