Slash and burn along with the encroachment and deforestation of the hill forests is detrimental to the conservation of the remaining dipterocarp forests. This paper describes the distribution, status and threats to the dipterocarps in Bangladesh and give emphasis for an urgent need of arresting the further degradation of the remnant dipterocarp forests of the country. Appropriate strategies and action plans are the immediate needs to conserve, regenerate, protect and sustainable management of the last dipterocarp forests in Bangladesh.<\/FONT> <\/FONT> Keywords:<\/SPAN><\/B>Dipterocarps, Deforestation, Plantation forest, Biodiversity, Short rotation species<\/B><\/SPAN> <\/SPAN><\/B> <\/SPAN><\/B> Introduction<\/SPAN><\/B> <\/SPAN><\/SPAN><\/B><\/SPAN><\/B> Bangladesh<\/SPAN> is one of the most densely populated countries of the world with a population of 133.4 million and the density is about 904 per square kilometer <\/SPAN>and population growth is the most serious problem of the country (Anon 2003). The country lies in between 20o<\/SUP>34‘<\/SUP>N and 26o<\/SUP>33‘<\/SUP>N, and between 88o<\/SUP>01‘<\/SUP>E and 92o<\/SUP>41‘<\/SUP>E (Rashid 1977).<\/I> The majority of land is flat and formed by river alluvium from the Ganges and the Brahmaputra and their tributaries. The eastern and northeastern parts of the country consist of hills alternating with broad valleys (Das 1990). Maximum elevation of the hills is 1 372 m at Tazindong in Chittagong Hill Tracts. <\/SPAN> <\/SPAN> The total area of the country is 14.4 million ha of which 2.46 million ha covered by forests distributed all over the country (Table 1). The natural forests of Bangladesh consist of three major vegetation types occurring on three distinctly different land types (Hassan 1994). The natural hill forests of Bangladesh are characterized by a large diversity of plant species. An estimated 5 700 species of angiosperms alone, including 68 woody legumes, 130 fibre yielding plants, 500 medicinal plants and 29 orchids, are found in the forests of Bangladesh. Some 2260 species are reported from the Chittagong hilly regions, which falls between two major floristic regions of Asia (Anon. 1993). <\/FONT> <\/FONT><\/SPAN> Sources: 8th Round-Table Conference on Dipterocarps<\/FONT><\/I> <\/FONT><\/SPAN> <\/SPAN><\/FONT><\/FONT> <\/DIV><\/p>\n","protected":false},"excerpt":{"rendered":" Inland moist deciduous sal and wet-evergreen hill forests in Bangladesh were dominated by the Dipterocarp species of Anisoptera scaphula, Hopea odorata, Dipterocarpus alatus, D. costatus, D. gracilis, D. turbinatus and Shorea robusta.
