The vegetation of the coastal belt of ^a&ir”Pakifftan- has
never reached climax due to biotic interferences except in Chakaria
Sundarbans of Chittagong District, Patherghata of Bakherganj
District and Sundarbans of Khulna District. In Chakaria, Father— .
ghata and Sundarbans, the vegetation has reached edaphic climax.
An attempt has been made here to study some vegetational communities
in areas other than Sundarbans in order to find out firstly, the
type of vegetation naturally growing under the existing ecological
conditions and. secondly, to draw inferences as to the species
that may be successfully planted in the region.
