In this study we examined the climbers of\nSundarbans mangrove forest of Bangladesh (SMFB) in its 32\nrepresentative sites. The climbers of SMFB were comprised of 53\nspecies belonging to 46 genera under 20 families. 44 species were\nrecognized as vines and 9 species were lianas. 25 species of the\nclimbers were non-mangrove 19 mangrove associates and 9\nmangrove species. Species richness of the climbers was higher in\nthe sites of oligohaline zone than those of mesohaline or polyhaline\nzones. Climber density was higher at the forest edges than in the\ninterior forest and found as gradually decreasing with the increase in\ndistance from the edge. DAFOR scale recognized 46 species in rare\ncategory. Distribution of climbers exhibited a wide variation in\ndifferent gradient of saline zones. 16 climber species were found as\naggressive invasive affecting the growth development and\nregeneration of many other species of SMFB.
