Abstract
Moist deciduous Sal (Shorea robusta) forests are one of the most ecological and economically important forest types in Bangladesh. Therefore, the study was conducted to analyze the tree and shrub species diversity, vegetation covers and structural composition of the major Sal forests of the Madhupur and Bhawal region in Bangladesh. The Quadrat method was used to investigate the biodiversity patterns. Madhupur National Park (MNP) possessed an important diversity of 69 plant species belongs to 26 families and 55 genera. Contrary, Bhawal National Park (BNP) consisted of 28 plant species belongs to 16 families and 22 genera. However, 27 plant species were similar between these two forests and considering the important value index (IVI), Dipterocarpaceae family was the most dominant family in both MNP and BNP. In both forests, Sal was the most dominant species followed by Fulkhori. On the contrary, in both forests have considerable number of species having IVI value of less than 1, indicating these species needs immediate conservation strategy. However, these threaten ecosystems still have important numbers of plant diversity which creates attention to the policymakers as well as the forest department of Bangladesh.
