The paper describes the composition and status of regenerationin a proposed biodiversity conservation area (Bamerchara andDanerchara) Chittagong, Bangladesh. A stratified random quadratmethod was used to study the regeneration status. Total 143seedlings and saplings of 39 species under 18 families were recordedin the sampled area. Moraceae is the dominant family having 5species followed by Anacardiaceae, Euphorbiaceae, Myrtaceae,Mimosaceae, Combretaceae and Verbenaceae (3 species each). Tectonagrandis has the highest importance value index (31.05) followed byGmelina arborea (16.05), Mangifera indica (13.59), Erythrina variegata(12.53) Unidentified-2 (11.06), Bombax ceiba (11.05) Eucalyptuscamaldulensis (9.92) and Oroxylum indicum (9.65). The distribution ofall the regenerated species is contagious except Tectona grandis,which show random distribution The study of density, frequency,abundance, relative density, relative frequency, relative abundanceof various species showed that it is possible to bring the depletedarea under complete forest cover through the protection of naturalregeneration.
