Mangroves - one of the most productive ecosystems on the planet. Given the complexity of kelp forests – their variable structure, geography, and interactions – they pose a considerable challenge to environmental managers. mangroves provide food for coral reef ecosystems.Their fallen leaves become tiny particles called detritus, on which fungi residue.Many shellfish, shrimp, crabs, and tiny fish partake in an further decay of detritus and these animals are eaten by larger animals.This makes mangroves important to coral reef and commercial fisheries as well.

Discover how coastal ecosystems function. Part of her research includes carefully dosing individual mangrove trees with small amounts of nitrogen and phosphorus to understand how excess nutrients, which are a major global threat to mangroves and other coastal ecosystems —like those from industrial, residential, and agricultural sources—affect mangrove ecosystems. Mangrove Ecosystem. Sea levels are rising and the chemistry of the oceans is shifting (IPCC 2007 and NRC 2011). Mangrove forests make up one of the most productive and biologically diverse ecosystems on the planet. Yet, despite their high and wide-ranging social, economic and even cultural importance, mangroves are severely threatened. Fishermen are one of the livelihoods that until now still in demand. They form the first line of defense against violent waves and protect against storm surges. Wetlands are often viewed as wastelands, and no second thought is given prior to draining the land and clearing its vegetation to serve the people’s need and greed.

They grow in a variety of depths of salt water, their roots sticking up out of the mud, with fish, crustaceans and a host of other species living between tree trunks. In this review paper, world-wide status of mangrove habitat loss, role of mangrove to act as a sink of pollutants and carbon capture (carbon sequestration), accumulation and biomagnifications of heavy metals is discussed. Threats and management. Introduced species pose a serious threat to the ecosystems of south Florida including the Everglades. This is especially true in mangrove ecosystems, since they are open systems interacting with a high diversity of functional landscapes, such as borders with terrigenous freshwater, coastal ocean water, the atmosphere and the sediment-water interface. Threats to mangroves and solutions Although very complex and resilient to natural disturbances, mangrove ecosystems worldwide are endangered by human activity and are lost at a greater rate than inland tropical forests. It gives an overview about the characteristics, distribution, biota, functioning and adaptation to general problems the organisms are facing with. Another prominent type of ecosystem that naturally occurs in the Philippines, given the multitude of coastal areas of this country, is the mangrove ecosystem. Blue carbon ecosystems (mangroves, sea grasses and salt marshes) can be up to 10 times more efficient than terrestrial ecosystems at absorbing and storing carbon long term, making them a critical solution in the fight against climate change. mangrove swamps. Tweet This Trees in an area around one km2 at Napitkhali under Chandpai range of the world’s largest mangrove forests are burning rapidly. Threats to Mangroves; Climate Change. Okay, we have to start from this, below here they are the 20 threats to ocean ecosystems : 1. Climate Change
Threats to Mangroves
... Over Exploitation of Marine Life
Unregulated fishing is depleting fish stocks
As stocks of one become uneconomic to exploit people are simply turning to another
Decline in biodiversity, loss of income and jobs
Over fishing alters the food chain and webs and mangroves communities can be altered as a result

One relatively bright spot, at least in terms of mangrove protection, is Vietnam. Their range is now restricted to the mangroves of Playa Tortuga Negra and Caleta Black on the north-west coast of Isabela. Mangrove ecosystem is a very unique ecosystem in the Earth, which is under threat due to habitat loss, aquaculture expansion, overharvesting and increase of pollution load.

Mangroves in the context of a changing climate . Many small islands like Mauritius that have cleared mangrove forests in the past for touristic benefits are now actively engaging in replantation programmes. Mangroves are medium-size and highly tolerant flora that can survive in brackish water (water which is more saline than freshwater, but not as much as seawater).
