Natural regeneration status of native tree species in Dudhpukurta-Dhopachori Wildlife
Sanctuary (DDWS) In Chittagong South Fores! Division, Bangladesh was through
stratified random sampling method. A total of 120 tree species belonging tn If, families were
recorded from 125 plots of 5 m x 5 m in size. Moraceae and Euphorbiaceae families were
represented by maximum number (11) of species, where maximum individuals {TH) no. were
recorded for Dipterotarpaceae tantih from the sampled area (0.3125 ha). Family Relative
Density (FRD), Family Relative Diversitv (FRDI) and Family Importance Value (FIV) index ot
the regenerating tree species were highest for Diptenxarpacw < 15.), Moraceae (9-17 ■■! and Euphorbiaceae (20.5) family respectiveiv. Dtpfrtmirpj^ tarbiiMtas was represented b\ maximum seedlings per hectare (1078) foftowed by Cm™ nemsa (464) and Apumsrt ioJhiluf |4fi4). Seven biological diversity indices were also calculated which ensures promising regeneration status of DDWS. Percentage distribution of seedlings of all species was maximum (80.62%) for the height range of 0-50 cm. Number of seedlings were found to reduce proportimatelv with height growth that indkates poor recruitment of the seedlings in the Wildlife Sanctuarv area. However, Ar#ixutr5 citwa was found tn show maximum (8.91%) seedling recruitment percentage. Considering the findings, it is emphasized the need ot a management plan based on natural regeneration potential for the effective functioning of Dudhpukuria-1 fhopadmri Wildlife Sanctuary,
