Mangroves of Sundarbans can be recognized by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. The roots slow the movement of tidal waters, causing sediments to settle out of the water and build up the muddy bottom.
Mangrove forests are invaluable as they stabilize the coastline, thereby reducing erosion from storm surges, currents, waves, and tides. The intricate root system of mangroves also makes these forests attractive to fish and other organisms seeking food and shelter from predators. They also serve as a dwelling ground for a wide variety of fauna including the fabled Bengal Tiger.
