A growing country population puts ever-increasing pressure on forest to prepare, collect and hunt and gather natural resources. We cannot stop it as a means of preventing biodiversity loss; rather we need to modify our plans so that forest resources can be collected in such a way as to minimize biodiversity damage and renew their natural systems. According to the order of the government of Bangladesh cutting down of trees in the Sundarban has been banned from 2000-2010 (Hena and Mannan, 2008).The study area of this research covers the Sundarban forest and its adjacent coastal areas of Bangladesh. In this research it has been examined the steps to be taken to meet the demand of the objectives for assessing the impact of natural disasters on the biodiversity of the forest. The study has been conducted on the literature on before, during and after disastrous situation regarding Sundarban and its adjacent area. The adopted biodiversity approach is analytical in nature considering the objectives of the study. In this article, data from Rashid, 1991; Manju, 2001; Rouf, 2001; Poffenberger, 2000; Chaffey and Sandom, 1985; Siddiqi, 2001; Khan, 2003; Hena and Mannan, 2008; DPC, 2004; GOB, 2010; Dey, 2001; Knapp et al., 1989; Blower, 1985; Rashid and Scott, 1989; Ali, 1994; Day, 2001; Rahman, 2007; Forest Land, 2010; Smith et al., 1998; Agrawala et al., 2003 and BBS, 2006 have been used. Therefore, this study is a documentary research to find out the existing biodiversity management for different initiatives under taken at pre-, during and post- disaster conditions to draw a suitable conclusion for sustainable biodiversity management on Sundarban perspectives.
