Even, the unregulated discharge of solid from the industries become the most serious threat for the mangroves. Identify ways in which coastal ecosystems are connected. 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. Mangroves have (carbon) hoarding issues. That said, one comprehensive study of mangroves notes that climate change may prove to be the ultimate anthropogenic disturbance factor, resulting in a maximum loss of 10 15% of – mangrove ecosystems globally (Alongi, 2008). 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. Introduced species pose a serious threat to the ecosystems of south Florida including the Everglades. Natural Causes Natural Disasters, Climate Change and Sea Level Rise: Various natural calamities like cyclone, floods, storms, coastal erosion, naturally shifting hydrology, climate change and sea-level rise may destroy trees and animals even faster. Yet, despite their high and wide-ranging social, economic and even cultural importance, mangroves are severely threatened. 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. Raise awareness of the importance of mangroves in coastal ecosystem among SSGC staff, local communities and other private sector companies; Engage communities in the planting and conservation of mangrove ecosystems for their livelihoods. 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. Fishermen are one of the livelihoods that until now still in demand. Prev Next. Perhaps one of the most commonly identified services provided by mangrove communities is the provision of a nursery habitat for juvenile fish. Photo: Shutterstock. Climate Change
