Data collected from twelve permanent sample plots (PSP) in the Sundarbans
mangrove forest on seedling regeneration from 1981 to 1987 indicated two main
problems i.c., appearance of insufficient number of seedlings compared to die vast area
of seedling regeneration and failure of seedlings to survive and establish themselves.
Average number of seedlings appearing per year was 35,625/ha. There was, of course,
wide variation in the availability of seedlings among the plots located in different
representative areas of the forest. Of the total new seedlings, Ileritiera fomes constituted
41.27%; and Excoecaria agalloc.ha 54% while the remaining 4.73% were seedlings of
other species.
