Literature review:

A wetland is an area that is covered by water throughout the year or throughout parts of the year. Wetlands have many functions such as providing a home for organisms but more importantly filtering and cleaning the water. A wetland’s health can be determined through the organisms that live there and whether or not it purifies the water.

When testing for the health of the water one can test many aspects, and because water is the most important part of the wetland, it is important to test as many aspects of water to ensure its quality. Turbidity is finding if the water is clear or not. Turbidity is caused by suspended solid matter in the water and high can be caused by numerous things such as: soil erosion, algal growth and …show more content…

If the water is acidic or basic the chances of it being polluted is greater and because most organisms are only suited for certain pH levels [1] . Temperature of the water affects the type of life that live around the water. Temperature is important to water quality since it has direct corrolation to the amount of dissolved oxygen in the water. Temperature is also important to life in and around the water. Temperature can be triggers to hatch certain invertebrates and many aquatic life have perfered temperature ranges [1&2] . Hardness is how much dissolved calcuim and magnesium mineral is in the water, hardness is measured in ppm. Low hardness can be linked to errosion problems while high hardness can be bad for the health of the wetland. An ideal hardness should be around 60 to 120 ppm. Water hardness can be further calculated into calcium hardness and magnesium hardness. CaCO3 X 0.4 = Ca ppm and CaCO3 X 0.24 = Mg ppm respectively. While both these minerals in water may contribute to our daily intake of salts, too much of something is never good for one’s health [1] . Oxygen content is the amount of oxygen present in water. Plants and animals in the water both require oxygen in order to survive. …show more content…

Nitrates and nitrites in soil are important as they are part of the nitrogen cycle while also being essential to the plants in the wetland. Not only is nitrogen essential in the soil as it is the main site for the nitrogen cycle but it is also essential in plants as nitrogen is the base to form protein and is a component of the chlorophyll [3&4]. Water retention in the soil is also important as it provides the plants with water throughout the dry seasons such as winter and it also helps to prevent floods by absorbing most of the water. Clay being the most able to retain water and sandy soil being less likely to retain water

I organized four different tests; pH paper, alkalinity tests, the number of rocks neutralizing acid, and the number of rocks that don’t neutralize acid. The average for pH paper was seven. The pH is the numeric scale used to specify the acidity or alkalinity of an aqueous solution. The pH scale measures acidity and alkalinity. the pH scale goes from zero, which is an acid reading, to fourteen, which is an alkaline reading.

Gene Turner asserts that the 88 percent of the wetland losses are occurring without direct, on-site human effect. The book talks about four hypotheses but three are cast aside and Turner mainly believes in one. The two that were rejected blame the wetland loss to changes to the river, which then contributes to the deprivation of nutrients-rich sediment. The other dismissed hypothesis blamed the saltwater intrusion as the main culprit in the loss of the freshwater wetlands. The one that Turner strongly believes as the main reason is the one that blames the canals for the destruction of the wetlands.

Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters

One issue found is the creation of smelly phytoplankton that makes murky unclear waters along with aquatic impurities. Moreover, the reduction of growth due to poor light conditions and dying plants make it difficult for predatory fish to hunt leading to overpopulation. (Chislock, 2013) Eutrophication can be found in many of our water resources such as ponds, estuaries, and bays. One region with high areas with eutrophication is in a lake shared by Kisumu, Kenya and Kampala, Uganda.

These water samples were all taken from the shores of Barker Lake, meaning that they should be similar and they were. Our class data did not seem to be very precise. This is shown in the data in sites 1 and 2 when one group had 9 ppm and another group had 20 ppm. These samples both came from Salt Creek and should have been similar but were not. Another example of class data being inconsistent or imprecise was on site 4 when one group’s results showed 3 ppm and another group’s showing 6.

The author in the article about Florida 's Okefenokee Swamp, explains the primitive swamp and wildlife in southeastern Georgia and northern Florida. The author describes the place such as how it includes low, sandy ridges, wet grassy savannas, and islands. The writer supports the article by explaining the swamp being bounded on the east sandy Trail Ridge, which prevents direct drainage into the Atlantic. The author the describes the plants such as the exotic flowers, lilies and rare orchids. The article also explains the mammals which live among the swamp.

Comparison Contrast Essay Okefenokee swamp is described differently by two authors. One suggest a calm favorable tone and the other a frightened, dark tone. The authors’ message is to inform people of the harsh reality behind the life of the swamp and the true beauty it contains. Both authors each exhibit a distinctive style through their deep contrast of the Okefenokee Swamp using imagery, diction, and figurative language.

Since the bog is home to many types of rare plants, its ecological strucuture is quite unique and special. In particular, the sphagnum moss absorbs and holds moisture that is slowly released into the atmosphere. Because sphagnum is very water absorvant, acidic, and antiseptic, it has had many significant benefits to the Musqueam People, such as using the moss to disinfectant bandages and baby diapers. Of particular notice is the importance of water in the bog: water released in the bog is acidic, and it acts like a solution that prevents bacterial growth, slows decomposition, and reduces nutrition availability. In addition, dead/decayed plants create carbon sink: a natural or artificial reservoir that accumulates and stores some carbon-containing chemical compound for an indefinite period.

All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick. For the aquatic animals, these toxins attack mainly the organisms liver and nervous system (Nitrogen and

Gilded age Gilded age coastline has been losing its wetlands at a rate of 16.57 square miles a year during the past 25 years, equal to the loss of a football field of coast every hour. This loss of wetlands is due to pollution, deforestation, and erosion. The loss has caused has caused loss of biodiversity. Louisiana has lost 1900 years ago of land because of pollution from landfills, factory waste, and erosion.

A wetland is an area where the land is saturated with water and has wetland plants. Wetlands are important because they reduce the damages of flooding. The Everglades is a very large shallow wetland in south Florida. Tens of thousands years ago, glacial retreat submerged portions of the Florida peninsula and water level rose. Today, water discharges from Orlando through the Kissimmee River and to Lake Okeechobee.

States can be heavily impacted by all of this wetland destruction. For example, Louisiana, approximately 40 percent of the country’s total wetlands area are located in Louisiana. It sates in the passage “Wetlands and Habitat Loss” that Louisiana is located at the drainage gateway where the Mississippi River meets the Gulf of Mexico. This is why Louisiana holds such a great percentage of the United States Everglades. If you take away wetlands in states like Louisiana, then there would no longer be anywhere for natural habitats to inhabit creatures that need that type of environment to survive.
