This paper presents the assessment of both the natural and planted species
diversity of the Sitakunda Botanical Garden and Eco-park, Chattogram. A total

disturbed, undisturbed and planted areas. Among them 153 plant species
recorded from the natural undisturbed area belonging to trees (45 species),
shrubs (44 species), herbs (34 species) and 30 species of climbers. Fifty two
species were documented from disturbed and planted areas. Mikania cordata,
Chromolaena odorata, Hyptis suaveolens, Mimosa pudica and Ageratum
conyzoides are dominant species in the disturbed zone and Ficus hispida are the
most dominant tree species in the undisturbed zone. The highest Importance
Value Index (IVI) showed 28.08 for Holarrhena antidysenterica and the lowest
1.05 for Mangifera sylvatica in natural patch. Syzygium fruticosum showed the
highest IVI of 27.81 and Pinus caribaea showed the lowest (0.93) IVI in
plantation site. Most of the species are regenerating from the root suckers.
Protection measures shall help the regeneration and conserve the species
diversity in this Botanical Garden and Eco-park.
