Mangroves are present in the Nellyadi river area, where Avicennia officinalis is the dominant species. Other mangrove species present in the area are Avicennia marina, Acrostichum aureum and Kandelia candel with 40-70 % density.

Mangrove forests are critical ecosystems that are found along tropical and subtropical coastlines. These forests are home to a wide variety of plant and animal species and provide important environmental services such as stabilizing the coastline and protecting against erosion. However, human activities such as aquaculture and deforestation have fragmented and destroyed vast expanses of mangrove forests. In addition, threats such as oil spills, overfishing, and destructive fishing practices have put these ecosystems at risk.

Despite their importance, mangrove forests only cover about 1% of the world's tropical coastline. If current trends continue, many experts believe that these forests will disappear completely within the next 50 years. There are about 80 different species of mangrove trees, all of which are adapted to living in low-oxygen soil and flooded by tidal waters. These trees are easily recognizable by their dense tangle of prop roots that make them appear to be standing on stilts above the water.

The unique root system of mangroves allows them to withstand the daily rise and fall of tides, and also slows the movement of tidal waters, causing sediments to settle out and build up the muddy bottom. This is important because it helps to stabilize the coastline and reduce erosion from storm surges, currents, waves, and tides. In addition, the intricate root system provides habitat and food for a variety of fish and other marine organisms.

It is crucial that we take action to protect and preserve remaining mangrove forests. This means reducing human activities that are harmful to these ecosystems, and implementing effective management and conservation strategies. Without mangrove forests, coastal communities and ecosystems will be at greater risk from the impacts of climate change and other environmental threats.
