The original areas of Bangladesh were covered with monsoon forests, which are now severely degraded and have been replaced by agricultural land. As a result of human overexploitation, forests now cover only 14% of the country.

In the Chittagong Hills (an area about 350 km (217 mi) long along Bangladesh's border with India and Myanmar), moist equatorial forests grow, covering an area of about 4,500 km2 (1,737 sq mi). The teak tree, which is used in construction, is found there. Other species found there are: Telsur, Mahogany, Simul and Bamboo scrub.
