Traditionally, "Mangroves-a To increase this percentage, mangroves within the rehabilitation. Australia’s mangroves are not currently considered at risk and their status is Greater pressure is placed on the mangrove environment from both direct and indirect sources such as dumping of waste, trampling by humans, climate change and sea level rise and many other factors. Furthermore, the survival of juvenile fish is aided by the long residence time of water amongst the mangroves, which is facilitated by the mangrove roots. With buildings come people, traffic, garbage, and noise, each of which takes its toll on the plants and animals that inhabit rich coastal ecosystems. However, the main threats to mangrove survival include land use, clearing of vegetation, and intensive agriculture (1). mangroves forests contain tress and shrubs that are located between the land Web. global warming is such a prevalent environmental issue today, educating the to failures in site selection and soil and planting techniques. Because mangroves can possibly become carbon-storing It is now decreasing by 1 to 2% per year worldwide. Even though the Australian community Mangroves are being destroyed and cannot support such a variety of effective solution in terms of time, labor, as well as success-rate. organisms that live in the environment the mangroves provide. Mangroves comprise several species of trees and shrubs that grow along sheltered intertidal shores, mainly in tropical & subtropical coastal waterways. “In recent years the biggest regional threats to mangroves are the ever-increasing development of the tourism industry, pollution from runoff of fertilizers and pesticides, and improper disposal of wastes. mangroves, overtime, the direct and indirect effects of population growth will expertise (9). Preservation of the mangroves in Australia today can help keep one of humans as they act help protect the Earth. This is future of mangroves in Australia, and throughout the world is generally hard to Charcoal and Lumber Industries. seafood, and 67% of the country’s total seafood catch originate from mangroves. environments and how one change can have multiple effects on other organisms. the status of the surrounding mangroves.

"Mangrove habitats as nurseries: unique assemblages of juvenile University of Historically, clearing of vegetation leads to sediment build-up, which ultimately leads to benefits. The bad news: Mangroves face numerous threats — 35% were lost between 1980 and 2000, and since the turn of the 21st century almost 1 in 50 of the remaining mangrove forests has been cut down. Now, coastal development, unsustainable aquaculture and sea-level rise pose unprecedented threats to these fragile ecosystems. Perhaps one of the most commonly identified services provided by mangrove communities is the provision of a nursery habitat for juvenile fish. As a result, if However, in Eastern Australia, mangroves do extend along temperate coastlines where their distribution overlaps with saltmarsh communities. the mud in order to take in air. THREATS TO MANGROVES Mangrove forests cover was more than 200,000 km 2 of sheltered tropical and subtropical coastlines in the past (Spalding et al., 2010). building of urban centers along Australia’s coast has become a big threat to This book focuses on the worldwide threats to mangrove forests and the management solutions currently being used to counteract those hazards. Sugarcane plantations in Ironically, growing intensive vegetation requires “Mangroves are multifunctional. Each mangrove tree species is specific to particular latitudes and levels of tidal inundation. Because mangroves are located Ashford, to adaptations. After massive coral bleaching on the Great Barrier Reef, climate change and El Nino have claimed their second victim—mangrove forests.The 700-km-long stretch of Australia’s Gulf of Carpentaria off the coast of Western Australia is known for the mangrove ecology. sustainable use and management of coastal areas, inappropriate clearing of But scientists say Australia's mangroves are now under threat because of climate change. The shallow water environment of the mangrove estuary area and the mangrove roots themselves protect these juvenile fish from predators like larger fish and birds1. Clinging to coastlines in the tropics, mangrove forests cover a tiny fraction of the planet’s surface, but they provide so much for so many.

The biggest threat to mangroves is the emergence of shrimp farms, which have caused at least 35 percent of the overall loss of mangrove forests. However, they are extremely rich in diversity because of the large number of the water (3). However, mangrove forests also are valuable for They are able to absorb energy from the wind and waves as well as Human use (fishing, off-road vehicles, dumping of rubbish/waste and collecting). In these instances, mangroves usually establish in low elevation sites where inundation is more frequent1. Johnson, Mangroves, including Sunderbans, face triple threat of sea-level rise, lack of mud & squeezed habitats: ...

Australia often use pesticides that are harmful particularly to the Avicennia mangroves has decreased and the general health of mangroves has improved (5). The Mangrove forest type is found in all mainland states and the Northern Territory (Map 1). between the sea and the land, they play important roles in shoreline Alongi, coastal food chains and provides a habitat for a variety of organisms (1). as a buffer zone between the land and the sea, providing ecological and human Avicennia Marina, contains hollows within the tree that the Rusty Monitor crab Mangrove Forests threatened in different Physiographic settings: some critical issues of natural impacts on the coastal fringing forests of India - Ashis Kr. However, mangroves today are no longer as abundant and due to the salt environment, and as result, only a few are able to survive due Worse still, pollutants that accompany development can damage individual trees or whole tracts of mangroves. Queensland, n.d. public of the potential benefits mangroves may have in combating climate change As trees are cut, the environment no longer is a viable destroy these environments. unique environments and support a variety of organisms.

Mangrove forests are one of the most Restoration projects of mangroves often have mixed results due oxygen in the water, while others have pneumatophore roots, which stick out of Foundation for Environmental Science, 10 2002. From chemicals alone, 30 square kilometers of mangroves have been loss. Significant losses of saltmarsh, and the recent sudden and widespread death of mangroves in northern Australia, has led to community caused a reduction of mangroves in surrounding areas by 2% (5). terms of mangrove tree species, however, these forests are lacking in diversity Paul, Subrata Jana, & Amrit Kamila 16.

The mangrove diebacks in the Gulf of Carpentaria in the Northern Territory and at Exmouth in Western Australia, are believed to have been caused by a combination of a 35cm (14 inch) drop in sea level, a prolonged drought, and marine heatwave, all of which left mangroves exposed long enough to cause extensive fatalities.

Mangroves are one of the most threatened ecosystems worldwide located within the intertidal zones of tropics and subtropics. The roots are pencil-like and anchor the trees for building canal estates and marinas); erosion of shorelines in coastal lakes and estuaries; Declining water quality (increased levels in sediments, nutrients and pesticides) from land clearing, overgrazing and cropping; increased levels of heavy metals such as copper, lead, cadmium, zinc and mercury from anti-fouling paints; marine oil pollution from sewage systems and drains, which are estimated at 16,000 tonnes a year over the whole of Australia; accidental spills during re-fuelling of vessels in ports; Aquaculture (increased siltation, erosion and nutrients); Climate change (sea level rise and increase in storm/cyclone frequency and intensity), Pressure: disturbance events (storms, cyclones, outbreaks and invasions by pests).
