The beel is endowed with rich floral and faunal diversity. In addition to huge congregation of residential water birds, the Deepor ecosystem harbours large number of migratory waterfowl each year. Deepor beel has been designated as a Ramsar Site in November 2002.

Justification for Designation as Ramsar Site
Deepor Beel is one of the largest and most important beels in the Brahmaputra valley of lower Assam and is a representative wetland type found within the biogeographic province, 'Burma Monsoon Forest'.
The lake supports threatened species of birds like spotbilled pelican, lesser adjutant stork, greater adjutant stork, blacknecked stork, and large whistling teal.
The lake is one of the staging grounds on the migratory flyways for several species. Some of the largest congregations of aquatic birds in Assam can be seen here, particularly in winter.
It supports 50 fish species belonging to 19 families. The diversity and concentration of indigenous freshwater fish species is very high. Natural breeding of some of these species takes place within the beel itself.
