INTRODUCTION |
Wetlands are defined as lands transitional between terrestrial and aquatic eco-systems where the water table is usually at or near the surface or the land is covered by shallow water (Mitch and Gosselink, 1986). The value of the world's wetlands is increasingly receiving due attention as they contribute to a healthy environment in many ways. They retain water during dry periods, thus keeping the water table high and relatively stable. During periods of flooding, they mitigate floods and trap suspended solids and attached nutrients. Thus, streams flowing into lakes by way of wetland areas will transport fewer suspended solids and nutrients to the lakes than if they flow directly into the lakes. The removal of such wetland systems because of

    Despite the expense and uncertainty associated with replacing the lost ecological services of wetlands, urban and rural development continues to impact wetlands. Preventing the loss of wetland functions is a challenge, particularly when financial gains for development seemingly outweigh non-market wetland values for the greater community. To address this concern, economic values can be assigned to the important roles of wetlands. This can be done through an economic valuation that aims to make ecosystem goods and services directly comparable to other sectors of the…

    For many years wetlands were seen as only a mosquito infested area. Nowadays they are highly valued ecosystems that are being protected for future generations of wildlife, and also people. A wetland is an area of land that is temporarily or permanently inundated. Sydney’s Bicentennial Park is home to 58ha of intertidal wetlands. Sydney Bicentennial Park is located within Homebush Bay (33 51' S, 115 33' E) and is approximately 12 kilometres west of Sydney’s CBD. The intertidal wetland has formed along the southern edge of the Parramatta River. The 58 ha intertidal wetland is made up of 40 ha of mangrove forest, 10 ha of open, shallow water- the waterbird refuge and 8 ha of saltmarsh.…

    California has suffered a historical wetland reduction of 91%, and there are currently fifteen wetland areas remaining in San Diego counties, which is a fraction of what there used to be. These wetlands consist of estuaries, lagoons, marshes, and sloughs (Seaworld). By definition, an estuary is the tidal mouth of a great river, where the tide meets the current of fresh water (Oxford English). Lagoons are a shallow sound, channel, or pond near or communicating with a larger body of water. Marshes are a tract of soft wet land usually characterized by monocotyledons (as grasses or cattails), and sloughs are places of deep mud or mire. (Merriam-Webster). For our project, we noticed that less than 5% of our map consisted of…

    Fertile soil, with moss embedded, is scattered near the extensive bodies of water present. Animals coexist in harmony with one another in this ecosystem, known as the Everglades. Wetlands are a natural part of our earth, and an essential place for wildlife to thrive. However, the wildlife's health has been decreasing continually in the Everglades due to water pollution/depletion and its negative effects. This issue can be ended by ceasing further human development of the Everglades, hindering the process of over draining and uneven water distribution, addressing regional degradation by increasing water quality, and investigating the impact of currently enacted Everglade's water management systems.…

    Aquatic ecosystems account for the majority of the earth, and affect not only the organisms living within them, but all other organisms as well. Because these ecosystems are so vast, and have such impacts, it is important to understand how they function. To determine how an ecosystem is functioning, the stability of the ecosystem is taken into consideration. Stability is defined as the tendency of a system to return to equilibrium after being disrupted (DeAngelis 1980). Three factors affect the stability of an ecosystem: energy flow, nutrient cycling, and biodiversity. All three factors are directly related. Increased biodiversity in an ecosystem makes more paths for nutrients and energy to move through, and the more nutrients and energy moving through the system, the more biodiversity.…

    This is due to the colorful ecosystem it supports. In paragraph 6 of "Wetlands and Habitat Loss", Elaine Mao states "Due to their unique characteristics, wetlands can support a wide diversity of plants, mammals, reptiles, birds and fish". To reiterate, the unique ecosystem found in wetlands, provide favorable conditions for a diverse set of organisms to live in. Furthermore, wetlands, such as those found in Louisiana, can serve as a sanctuary for endangered animal and plant species. Once more, in paragraph 8 of "Wetlands and Habitat Loss", Elaine Mao writes "The wetlands are a crucial resource for many endangered species. In fact, more than one‐third of the United States’ threatened and endangered species live only in wetlands, and more than one‐half use the wetlands at some point in their lives for breeding, nesting or raising their young". Many of these endangered species, would likely not even be here today, if it wasn't for the…

    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…

    “Since nineteen thirty seven, Ducks Unlimited has conserved and restored more than thirteen million acres of the most critical habitat for waterfowl and other wildlife. Wetlands are among the most productive ecosystems on the planet. They are invaluable not only to waterfowl and scores of other wildlife species, but also to the very quality of life on earth.” (Wetlands and Grassland Habitat, 1). This is explaining how important these biomes are to planet earth. And like I had said before, without them the world wouldn’t be as nice as it is today. “A recent study estimated that one acre of wetland can store over one and a half million gallons of flood water.” (Wetlands and Grassland Habitat, 2). These biomes produce clean water that is used in our homes, that’s another way that they contribute. “Many wetlands help recharge underground aquifers that store ninety seven percent of the worlds unfrozen fresh water. Many Americans rely on groundwater for their drinking water, and recharge is important for ensuring a sustainable supply.” (Wetlands and Grassland Habitat, 2). Another way that this biome contributes to fresh water levels and to the water in our homes. Ducks Unlimited conserves by restoring grasslands and watersheds, replanting forests, working with landowners and partners, acquiring land, conservation easements, management agreements, and geographic information systems. These are a few ways that this…

    If governments continue to use a state-pressure-response model for the management of the lakes, many environmental changes will go undocumented and untreated, see Figure 1 in Appendix (MacDonagh, 2009). Numerous studies have predicted that climate change is expected to significantly decrease water levels in lakes and streams throughout North America (Mcheyie, 2007). Decreasing water levels in the Great Lakes will increase their vulnerability to toxic contaminates (Valiante, 2008). It would be greatly beneficial for environmental management models to already begin taking into account and monitoring these changes to lessen the effects of climate change. Stricter environmental policies for industries and farming practices should already be in consideration to prevent environmental concerns in the future. The environmental regulations that will need to be enforced will require much thought as well, such as debates over using a cap and trade or other emissions cutback strategies to lessen industry emissions if is required. The sooner these issues are dealt with, the more equipped decision makers will be at solving future crises. Other future concerns pertaining to the increase of urbanization around the lakes, primarily Lake Ontario, will be another negative environmental factor needing monitoring and acknowledgement of ecosystem change. With urbanization it is expected that natural vegetation will be removed and replaced with impermeable concrete surfaces which allow water to flow directly into river channels, increasing sedimentation and pollutants in runoff (Foote, 1996). Sedimentation describes the process of depositing sediment or gravel. An increase in this process will have effects felt by the entire ecosystem. Domestic water supply will be contaminated and suspended sediment will have…

    ConservationPreservation of the wetlands in Oregon is done by not allowing population growth to take over these areas and allowing nature to remain untouched. Preservation of the areas is needed because wetlands are considered to be among the most productive ecosystems. (Jackson Bottom Preserve, 2008) Natural regulation is best seen in the preservation sites for wetlands. Since the preservation site is unchanged by man, the wetland is able to regenerate and degrade on its own, meaning that the wetland will go through various stages of nature without mankind interrupting the course. Therefore, wetlands maintenance is a value because of the benefits they bring us like, pollution and sediment filtration; food, shelter, breeding and resting places for local wildlife and not to mention the value of education and recreation purposes as well. (Jackson Bottom Preserve, 2008) This is where conservation takes a part in maintaining the ecosystems. Conservations unlike preservations mean that man has to help in the management of the land. Conservation of the wetlands has taken place to protect the loss of wildlife in our ecosystems. Oregon has gone to the lengths of going into areas deemed as a wetland and restoring them to what we believe would be a natural site. The difference here is that we are changing the landscape to reflect what the preserved sites look like. Whereas, with the preservation sites we only have to keep the land protected by law for non-development purposes. The similarities between the two are obvious because the goal is that the end results means that both preservation and conservation wetlands means protecting the environment and restoring it to retain the value for the…
