Natural Diversity of Bangladesh - Distribution of Plants and Animals

 

Bangladesh is a small country of an area of about 1,47,570 square kilometers.

 

It'is situated in between 20û34¡ and 26û38¡ northern latitude and 88û01¡ and 92û41 eastern longitude. Though the country is small yet the plant and animal resources is not so little. River washed Bangladesh is the largest delta in the world, having characteristics of natural diversities. Growth rate of population in this country is very high. The density of population is increasing day by day. To meet the needs of this additional population, homesteads and furniture are being made, and cultivable lands are being procured by destroying valuable forests. As a result forestland is terribly destroyed. Many species of plants and animals are becoming extinct. Thus plant and animal resources are being lost. As a result the topography (land forms) of this country is being changed very rapidly.

 

The nature of any region is the combination of various inorganic components like topography, climate, rivers and canals, mountains and hills etc. The nature and natural flora and fauna of a particular region together form the natural environment of that region. The characteristics, which prevail in a particular natural environment, are known as natural characteristics of that region. The natural environment of a particular region is dependent on the topography and climate of that region.

 

Bangladesh may be divided into several regions on the basis of topography or landform. The environmental components, flora and fauna of this region are full of special characteristics.

 

Some of these are discussed below: Recent flood plain 2. Haor and marshy lands 3. Pleistocene uplands, 4. Tertiary hilly region 5. Coastal mangrove forest and 6. Saint Martin's Island.
