Intertidal Wetlands Notes
INTERTIDAL WETLANDS
• Intertidal wetlands develop in coastal areas which are subject to periodic inundation by salty water
• They are found in estuarine environments in the limits of the tidal range
• Previously thought of as mosquito infested wetlands, they are now considered highly valued ecosystems which protect the quality of coastal waters and provides breeding grounds and habitats for a variety of marine life, are found along tropical and sub-tropical coastlines between 25ْN and 25ْC
• Dominated by mangrove trees which can survive partial submersion in salty water
• They protect the coastline from erosion, reduce storm water damage, trap sediment from runoff and provision breeding ground for many fish, invertebrate and plant species

The inter-tidal wetlands at Homebush Bay are located at 33°S and 151°E and are located to the west of Sydney’s central business district. The wetlands are 58ha in size, 40ha being mangrove forest, 10ha as a waterbird refuge and 8ha of saltmarsh. The wetlands are seen as an ecosystem that is at risk and have had contemporary management practices put into place to protect and conserve the natural area for future generations. The contemporary management practices for the wetlands include early contemporary, which did more damage than help, and late contemporary, which is proving to be effective.
The inter-tidal wetlands at Bicentennial Park required vital alteration due to the extensive negative impacts from early Europeans. Legislation and policies were employed as a late contemporary management strategy to obligate change and avoid further damage, particularly to the saltmarsh community which suffered extensive damage and is now listed as an endangered species. The major laws employed are the RAMSAR convention, JAMBA (Japanese Australian Migratory Bird Agreement), CAMBA (Chinese Australian Migratory Bird Agreement) and the Commonwealth and New South Wales wetlands policy. The sustainability of this contemporary

    Fresh water coming from Big Cypress Swamp combines with the Salt water in the Gulf of Mexico to create conditions that allow an amazing variety of life to flourish in features such as oyster bars, mangrove islands, tidal mud flats, and seagrass beds. While tidal mud flats and sea grass beds are important features the most prominent are the Oyster bars and Mangrove Islands. The Oyster bars and Mangroves are crucial in creating and continuing to develop the islands and characteristics that make up this region. Oyster Bars are formed by quartz sand carried by the current and deposited in deeper water parallel to the shore and eventually builds until it reaches the surface. If the conditions are right oysters colonize the sand deposits and the combination of oysters and sand create an oyster bar. Oyster bars gather nutrients by forming at right angles to tidal currents in order to catch nutrients from the incoming currents. Smaller branches form on the Oyster Bars and floating red mangrove seeds take hold in the sediments. Eventually multiple mangroves are caught and grow on the Oyster bar forming an island of roots and leaves. Overtime the mangroves arching prop roots will catch more sediment and the island will continue to develop eventually cutting off nutrients to the Oyster bar by restricting the currents that bring nutrients to the oysters. These structures help protect the region during storms, prevent erosion, and create Habitats for birds and fish. This is why more than 300 species of bird at some point are residents of the region as well as manatees and bottle-nose…

    Hastings Point is a small coastal town located in New South Wales that is sounded by a national park. Hastings point has been a great location for tourists due to its marine wildlife, beaches and fishing. This destination is home to a magnificent rocky shore perfectly suited for a vast majority and wide range of marine wildlife. The rocky shore has a wide spread of both biotic and abiotic factors which provides a suitable ecosystem for all wildlife but unfortunately this unindustrialized location is becoming over developed. This takes a toll on Hastings point ecosystem immensely because the estuary, beach and the living organisms are slowly diminishing in numbers whilst the waters of the estuary are being polluted and contaminated. This is due to the over populating and the rapid building development around the area. A few members of the community are trying to resolve this issue however the council is yet to act on their suggestions and if everyone continues to refuse to do anything about it then Hastings Point ecosystem will eventually get diminished.…

    An increasing human population has severely altered the ecosystem of Louisiana’s coastline. Human influence on the wetlands has diminished it 's size by thousands of square kilometers. Saltwater inundation has deteriorated much of the freshwater plant life and levees built to control the flow of the Mississippi river have prevented any natural restoration. This has caused a reduction in the chance of forming new land while the current land is disappearing into the sea.…

    Florida Everglades

    Florida is home to one of the most famous wetlands in the country, the Everglades. The diverse array of plants and animals create a truly remarkable site to behold. Its sheer beauty and awe-inspiring scenery make the Everglades one of the most sought after, and protected wetlands in the country. However, the Florida Everglades has not always received the respect it deserves. In the past, the Everglades has been mistreated in many ways, from being used as a dump site for pets and waste, to being rained of its resources, the Everglades has surly seen its fair share of neglect. Be that as it may, other wetlands around the country aren't being treated as well as they should be either. Thankfully, government organizations have stepped in to stop this mistreatment. After all, wetlands, such as swamps, marshes, and bogs contribute to the well being of us humans. For…

    Hastings Point

    As a result of natural or anthropogenic actions, habitat may be lost and degraded (Adrian, 2015). In turn, this causes changes in bio-diversity, the variation of life on earth and the interactions between these organisms, and accordingly, the cessation of ecosystem services (World Wide Fund For Nature (WWF), 2015). Hastings’ Point is a biodiversity hotspot, and home to various threatened and endangered ecological communities (Department of the Environment , 2015). Although highly regulated in NSW, the clearing of all types of vegetation has placed Australia in the top ten land clearing nations in the world. In the past, between the years of 1984 and 1989, the Western Lands Commission allowed clearing licenses for over 560,000 hectares along the NSW Coast, particularly the Hastings Point (Figure. 1) (Department of Primary Industries, 2015) (Evans, 2015). This clearing increases sedimentation of waterways, erosion and lowers the quality of water in that of estuaries and ocean areas (NSW Government , 2015). Additionally, impoundments trap sediment eroded from upstream regions, resulting in potential downstream erosion, thus, stream bed depressing, and reducing habitat variability downstream (NSW Government , 2015). Consequently, this leads to the direct loss of native…

    Louisiana is the home of America’s wetlands. Louisiana’s coast can be defined in multiple ways. Gay Gomez, a resident of Louisiana, describes its coast as a place of interaction among land, people, and ideas rather than “just a place on the map” (Gomez x). While some view it as a twisting line of the shore, others view it as a large triangular coastal zone (Gomez x). The foundation of the wetlands was formed by the Mississippi River Basin sediments clay, silt, and sand which were carried and accumulated by the river (Dardis 3). Approximately every thousand years, the Mississippi River changes its course creating seven major deltas in central and eastern Louisiana (Dardis 3). Louisiana holds some of the largest wetlands throughout the nation such as the Atchafalaya Basin. It is the nation's largest river swamp and it contains almost one million acres of America's most significant bottomland hardwoods, swamps, bayous, and backwater lakes (“Atchafalaya Basin” 1). Louisiana’s wetlands make up an ecosystem which covers more than 10 thousand square miles and is home to various plants, animals, and insects (Jonas 1). The types of wetlands which are located in Louisiana are swamps, levees, beaches, estuaries, barrier islands, and a variety of marshes (“Types of Wetlands” 1). While Louisiana’s wetlands are extremely valuable, unfortunately, they are at risk. Louisiana’s land has been eroding and becoming smaller and smaller causing the plants, animals, and insects which call Louisiana’s wetlands home to become endangered, threatened, and even extinct. The loss of the land is not only…

    Louisiana Wet Land Loss

    The coastal land loss for Louisiana has become a growing concern for the people of Southeast Louisiana over the last decade. “Coastal Louisiana wetlands make up the seventh largest delta on Earth, contain about 37 percent of the herbaceous marshes in the United States, and support the largest fishery supply in the bottom 48 states”(Couvillion 2011). “Louisiana is home to two million people and it supports vital ecosystems, national energy security, thousands of jobs, and a unique culture” (Louisiana’s Coast 2013). “The wetlands loss, erosion, subsidence, climate change, sea level rise, storms surge, drought, continuous flooding, and saltwater intrusion all threaten the life of Louisiana’s Coast” (Louisiana’s Coast 2013). “Louisiana currently undergoes about 90 percent of the total coastal wetland loss in the United States” (Couvillion 2011). The understanding of the loss of land is crucial when determining a plan to restore the preservations. “Sustainability needs to be restored to the coastal ecosystem, or the land will continue to be loss at a rapid rate and the critical infrastructure will be damaged” (Louisiana’s Coast 2013). “The pipelines, offshore support centers, and other facilities constructed for coastal conditions will soon be subject to the open water of the Gulf of Mexico if not sustained” (Louisiana’s Coast 2013). “Fisheries and wildlife stocks will decline as spawning, breeding, and foraging grounds are lost to the engulfing water” (Louisiana’s Coast 2013). “The nation will lose priceless habitat whose essential value is recognized around the world” (Louisiana’s Coast 2013).…
