ABSTRACT
The paper describes the composition and status of regeneration in a proposed biodiversity conservation area (Bamerchara and Danerchara) Chittagong, Bangladesh. A stratified random quadrat method was used to study the regeneration status. Total 143 seedlings and saplings of 39 species under 18 families were recorded in the sampled area Moraceae is the dominant family having 5 species followed by Anacardiaceae, Euphorbieaceae, Myrtaceae, Mimosaceae, Combretaceae and Verbenaceae (3 species each). Tectona grandis has the highest importance value index (31.05) followed by Gmelina arborea (16.05), Mangifera indica (13.59), Erythrina variegate (12.53) Unidentified-2 (11.06), Bombax ceiba (11.05) Eucalyptus camaldulensis (9.92) and Oroxylum indicum (9.65) The distribution of all the regenerated species is contagious except Tectona grandis, which show random distribution The study of density, frequency, abundance, relative density, relative frequency, relative abundance of various species showed that it is possible to bring the depleted area under complete forest cover through the protection of natural regeneration.
