Over the past 100 years the Louisiana coastline has suffered greatly from biotic, abiotic, and anthropogenic factors. The abiotic factors include things such as hurricanes or overnutrition that influence the surrounding biota. The biotic factors that contribute to coastal erosion are things like the immigration invasive species and the emigration or extinction of local flora and fauna that help preserve the wetlands. Additionally, there are anthropogenic factors such as pollution that can have strong negative influences on the abiotic and biotic factors of the wetlands. Each one of these factors cause ecological disturbances to the wetlands at a frequency and intensity that is unmanageable for the local flora and fauna. There are currently certain measures that are being taken into consideration to slow or stop the erosion of the Louisiana coastline.
Abiotic factors are things that are nonliving that influence an environment and it's inhabitants. Some of the abiotic factors that are attributed to coastal erosion in Louisiana are hurricanes, tropical storms, elevation, sunlight, overnutrition, sea-level rise, and deposition. Hurricanes bring about larger waves which cause dune erosion or beach erosion (Clark et al., 1998). This is significant because beaches and/or the dunes of the beach serve as buffers to the coastline and the ecosystem. As the beach or dunes recede from the erosion caused by these large waves and an increased sea-level the flora and fauna that help sustain the area die off or retreat to a more habitable zone leaving the wetlands in a critical state often resulting in a total loss of the area (Stockdon et al., 2012). Due to the nature of the Gulf of Mexico large destructive storms such as hurricanes or tropica...

...n, the Louisiana wetlands are an extremely valuable asset to the State of Louisiana and the United States. The continual loss of Louisiana wetlands has the potential to have an immensely negative effect on the economy at a state and national level. Over 2 million people live in the Louisiana coastal parishes (Field et al., 1991). The majority of people living on the Louisiana coast make their living from things that are directly related to the wetlands. The Louisiana wetlands make up the largest wetland community in America and is being lost at a rate greater than the other wetland communities in the country. The suggested strategies that are being taken into consideration could be helpful but it seems that the State of Louisiana is not as concerned as it should be given the future consequences and much like climate change coastal erosion is not being taken serious.
Investigating the Geographical Processes that are Affecting the Physical and Built Coastal Environment There are three geographical processes that are affecting the physical and built coastal environment, they are; erosion, deposition, and transportation. Erosion is the group of natural processes, including weathering, dissolution, abrasion, corrosion, and transportation, by which material is worn away from the earth’s surface, this is mainly caused by wind, running water, and waves breaking on the coast. Deposition is the depositing something or the laying down of matter by a natural process. Transportation is when sand is moved along the coast by long shore drift. At North Cronulla beach erosion is evident.
I live in Houma, Louisiana so I have tons of experience with the bayou region of South Louisiana. Everywhere I look in Houma there is a bayou, which is a good and bad thing. With a bayou comes many great things such as Egrets, Spanish Moss, etc. The bad thing about seeing many bayous is that it is a constant reminder that one day, Houma might be a part of the Gulf of Mexico. Also my dad’s side of the family is from Chauvin and Golden Meadow which is not too far from where the real damage of eroding wetlands is. I go down to Chauvin sometimes to visit my Nanny and her husband. I always see houses on stilts because of possible flooding that could come if a hurricane passes through. One of the issues that Mike Tidwell caught my interest was that the wildlife in bayous will one day be diminished into smaller numbers. That is because the eroding land causes brown shrimp, crabs, and other seafood to die out. Many residents in South Louisiana make a living off of seafood so to have most of that industry die out will hurt the economy of South Louisiana. I just found this issue very interesting.
The first mitigation banking guidance was released in 1995 by the EPA and Corps of Engineers. The most recent wetland mitigation banking guidance was released in 2008. The idea behind both wetland mitigation banking and conservation banking is to provide compensation for unavoidable impacts to resources prior to the environmental impact taking place (FWS, 2003). Based on the rules set forth in section 10 of the Rivers and Harbors Act and section 404 of the Clean Water Act, wetland impacts are reduced by using the following sequence of steps: avoiding impacts, minimizing impacts, and as a last resort, mitigating for impacts. Although the Corps has enforced a mitigation policy to reg...
This is a very critical situation that needs to be fixed urgently. The habitats of the Everglades depend on an annual water cycle which has been hindered by the development construction which was imposed on the farmland. Back in the 19th century, developers were keen on draining all the swamps in the Everglades for developmental purposes. Their intention was to grow sugarcane plantations on the land yet sugarcanes are highly destructive to the Everglades. They too disrupt the water cycle to which the wildlife has adapted. The Florida sugar industry built on the southern Shore of Lake Okeechobee directly clocks the water source for the remaining Everglades hence destroying the habitats of the wildlife existing in the affected areas.
Fifty percent of the original wetlands doesn’t even exist today. The water supply in the Everglades is changing and that has affected the Everglades in many ways. For one, population is decreasing and mankind needs to restore it somehow. Next, the Everglades are in need of some money to do that restoration, but where will they get it from? Last, the water supply is poisoning the humanity around it with much bacteria and many bad and dangerous elements. The Everglades water supply affected it in fixing the Everglades and wildlife.
... consider some ideas of what can be done to further enhance the management of the coastal issue. Using the research action plan, I aim to acquire a sophisticated understanding of longshore drift, coastal management and implementations of coastal issues, through the research action plan. Most importantly, I will include various diagrams explaining how the process of longshore drift occurs and what implementations it has on coastal environments, accompanied by an explanation of how the issue is being managed, a detailed outline of the geographical processes involved and a discussion of the impacts of the issue and why it is important.
DUI’s vision is, “…wetlands sufficient to fill the skies with waterfowl today, tomorrow and forever.” The site’s main focus stays true to DUI’s vision; protecting important waterfow...
Maintaining ecological diversity is necessary for the survival of a biological community. In the United States, American citizens are on the verge of irrevocably damaging one of the country's most unique and diverse treasures - the Florida Everglades. This national park is now the only remaining patch of a river that used to span 120 miles from Lake Okeechobee to the Florida Bay. Dikes and levees created by the Army Corps of Engineers in the late 1940's drained this river to reduce flooding and increase useable water for the development of the region. This major diversion of water lead to a trickle down effect causing the continual decline of the environmental state of the Everglades. Since then, debates over the Everglades' future have silently raged on for years about how, why, and when the restoration will begin. This ongoing, but virtually unproductive effort has cost taxpayers a great deal without any apparent benefits. Recently, this debate has been amplified by the voices of the sugar industry in Florida, which was attacked for its major contribution to pollution of the Everglades. Now debates rage on with a new effort called the Restudy. Backed by the Army Corps of Engineers, this effort would change the flow of the Everglades, potentially restoring it into the viable community of life that it used to be. The question now is, will this latest attempt to restore the Everglades ever be realized (thus ending the cyclic Everglades debate) or will it simply add up to one more notch on the bedpost of inadequate and failed attempts to save this national treasure. The world is watching to see how the United States will handle this unprecedented cleanup.
Louisiana’s coast is considered a “working coast.” This means that it is home to infrastructure such as pipelines, highways, and ports that have great significance to the national economy. Coastal erosion wears away at these industries causing a
The Florida Everglades have been slowly and steadily diminishing in size for over many decades. Throughout the years, the Everglades have had an abundant, healthy environment. The massive swamps were once rich with marshland, and had ecosystems chock-full of wildlife. However, due to large corporations, natural disasters and most importantly, the growth of the human population, the Everglades are 50% smaller than they were hundreds of years ago. The destruction of the Florida Everglades includes not only a diminishing number of the marshland, but also the lessening of wild life, such as alligators, herons, and exotic plants. While there is a government plan set for the restoration of the everglades, it will take many years to make up for the
The Everglades, classified as a wetland or a "transition zone" can support plant and animal life unlike any other place. Wetlands are an important resource for endangered species and "that more than one third of the United States' threatened and endangered species live only in wetlands." Says Elaine Mao, the author of Wetlands and Habitat Loss. People have started to notice the importance and the role of wetlands like the Everglades and how they are valuable and essential for ecosystems to live. Wetlands provide so many kinds of plants, mammals, reptiles, birds, and
The Florida Keys is one of the most famous and most visited archipelagos in the world. Contrary to what many people think, though, the Florida Keys do not begin at Key Largo. To the north lie nearly 50 more keys (ancient coral reef islands) that are mostly undeveloped pieces of land. Great adventures await you as you venture from the mangrove shoreline out to the coral reefs of Biscayne Bay. Biscayne Bay is a shallow estuary, managed by the National Park Services along with Florida Wildlife Commission and many others. The bay serves as a nursery for many infant and juvenile marine life species that need protection until big enough to survive in the open ocean. Large healthy seagrass beds provide hiding places and food for many of the animals living on the reef. Protected by a chain of islands or keys off shore and the mainland to the west, the bay is one of the most productive ecosystems in the park. It is comprised of four different ecosystems; the two major ecosystems are beneath the bay 's clear waters: hardbottom and seagrass.
One of the major problems affecting, not only oceans around the world, but also many local bodies of water right now is the problem of ocean acidification. You may have heard of ocean acidification, which you may have just disregarded as a problem that affects the large oceans as a whole. However, this acidification also affects the Chesapeake Bay itself. I have come to realize that the acidification of the Chesapeake is a major problem that will affect the diverse ecosystem that all the wildlife is located in, but also the many businesses locally and throughout the state that depend on the health of the ocean and the wildlife located in the
Globally coastal wetlands are disappearing at an alarming rate, the problem is most of society does not realize the value of these precious wetlands. Coastal wetlands provide an important role in the coastal ecosystem. “Coastal wetlands provide critical services such as absorbing energy from coastal storms, preserving shorelines, protecting human populations and infrastructure, supporting commercial seafood harvests, absorbing pollutants and serving as critical habitat for migratory bird populations”(Anonymous, 2011). Coastal wetlands are an economical asset as well as an environmental one.
Agriculture also leads to soil erosion, both through rainfall and wind. This soil can damage the aquatic ecosystems it ends up in, an...
