The Sundarbans mangrove forest is well known for its rich biodiversity and probably has the maximum flora and fauna as compared to
other mangrove forests of the world. Prain (1903) reported 334 plant species in the Sundarbans and surrounding areas. It is a matter of concern that there is a loss of biodiversity in the Sundarbans mangrove forest. Sattar and Faizuddin (1998) reported that one species of Bruguiera, that is B. parviflora, has become extinct, and many other plant species such as Luninitzera racemose, Xylocarpus granatum, Aviceunia marina, Rhizophore mucronate, R. apiculata, Kandelia candel, Excoecerie indice, Cynometra remiflore and Amoora cuculate are already threatened. Chaudhuri and Naithani(1985) did not mention the presence of B. parviflora in the Indian part of Sundarbans but noted its presence in the Andamans mangrove forests. It used to be found associated with other mangrove species in the Sundarbans on the bank of rivers and creeks (Naskar and Guha Bakshi 1987). The timber of B. parviflora is used as fishing pole and firewood. It is also a fodder plantfor deer and other herbivorous animals.
