Sporadic mortality of Sundri (Heritiera
fames Roxb.) due to unknown causes
was mentioned in the working plan of
Sunderbans in 1931 by S. I. Curtis. But the
mortality was not pronounced due to
removal of Sundri along with firewood
by permit holders. After 1971 working was
closed for a few years and as such accumulation
of dying Sundri in large number
attracted the attention of the foresters
(Sattar 1977). The total timber loss due to
mortality of Sundri was found to be 1.44
million cubic metres and the total financial
loss on the basis of valuation of 1976 was
Tk. 2000 million (Shafi 1982).
