Why do we need to protect mangroves?
The sturdy root systems of mangrove trees help form a natural barrier against violent storm surges and floods. River and land sediment is trapped by the roots, which protects coastline areas and slows erosion. This filtering process also prevents harmful sediment reaching coral reefs and seagrass meadows.
Why do we need to protect and conserve mangrove swamps?
Mangroves are the first line of defense for coastal communities. They stabilize shorelines by slowing erosion and provide natural barriers protecting coastal communities from increased storm surge, flooding, and hurricanes.
Why do we need to protect and conserve tropical rainforest coral reefs and mangrove swamps?
Together the coral reef and mangrove ecosystems form a barrier that protects shorelines from the destructive forces of wind, waves and driven debris. These living structures decrease the erosion and physical damage that can often impose significant economic and environmental costs on coastal communities.
What is the importance of mangrove forests 4 reasons?
They perform important ecological functions like nutrient cycling, hydrological regime, coastal protection, fish-fauna production, etc. Mangroves act as shock absorbers. They reduce high tides and waves and help prevent soil erosion. They also provide livelihood opportunities to coastal communities.

How do mangroves benefit humans?
Mangroves are important to people because they help stabilize Florida’s coastline ecosystem and prevent erosion. Mangroves also provide natural infrastructure and protection to nearby populated areas by preventing erosion and absorbing storm surge impacts during extreme weather events such as hurricanes.
How long do mangrove trees live?
How old do mangroves get? Answer: There is only little knowledge about the age of mangroves. Investigations on Rhizophora mucronata showed that the age can be 100 years plus.
What kills mangrove trees?
Diverting water can harm mangroves by preventing their seeds from being dispersed via seawater, and it can kill the trees by cutting off freshwater supplies. When diverted inland, seawater may contaminate farmland or freshwater below the ground.
Why are mangroves dangerous?
They require the perfect amount of sea water — too little and they dry out; too much and they drown. Sea-level rise is changing where mangroves can grow and threatening their continued existence in some of the places where they are most needed.
