Analysis Of The Riverine Ecosystem Of The Nisqually River And If So What Are The Declines Caused By?

The health of the Susquehanna River and Chesapeake Bay was found based on Biological (macroinvertebrates and wildlife) and Chemicals characteristics (pH, dissolved oxygen, phosphates, nitrates, etc.) as well as physical observations (amount of forested buffers, wetlands, etc.) Overall it was concluded that the health of the water was good to excellent. What was found was that many of the macroinvertebrates found in the water were sensitive or facultative, meaning the water quality was good enough for them to live in. Also, the level of ph, temperature, dissolved oxygen, phosphates, nitrates, and turbidity showed that the water quality was good. Finally, while we were canoeing down the Susquehanna River, observations were made on the land

The Neuse River has played a vital role throughout much of the history of North Carolina. In recent decades however the river has seen degradation of its health and ecology via massive amounts of point and non-point source pollution. The result has been numerous events of eutrophication, resulting in the ecological “dead zones” found throughout the river. Notable contributors of this pollution have been industrial plants and agriculture, most notably power plants and hog farms. As a result, federal and state agencies have enacted strict regulations and water quality standards and procedures to monitor the tributaries, estuarine areas, and main stem of the greater Neuse River watershed.

The Econ River Wilderness Area is an amazing little swatch of how central Florida used to be. It was interesting to see how many different ecological areas there were in that small bit of land, I believe that we counted 7 in total. Each of these habitats were interesting in their own way and by walking through them and physically seeing how difficult it is to decipher a clear cut line between each habitat helped me appreciate them even more.

Historically, this region was host to communities of Native Americans (East West Gateway Council of Governments, 2007, Leland, 1953). The abundance of freshwater and navigable rivers has attracted communities of people, and subsequently, commerce (Foley, 2000). Naturally, resources throughout the land have been extracted and utilized to further build these communities and attract prospective businesses. In the 19th century, this watershed was impacted by mining, logging, and grazing practices. In the early 20th century, logging dominated resource extraction (East West Gateway Council of Governments, 2007) which swiftly impacted the landscape. Ultimately, as logging stressed this region’s resources, state legislation allowed the federal government to purchase large tracts of land to establish national forest. Soon after, the national mobilization of the Civilian Conservation Corps, during the height

Hydrologic studies has always been the subdiscipline of environmental science that has most intrigued me; probably because the eco- and geological systems that comprise surface and shallow groundwater systems are so inexorably entwined and very delicate. Both of the virtual labs were interesting, and paint a clear picture of how we affect our hydrosphere and how that, in turn, affects us. Spotsylvania County and the city of Fredericksburg share four water treatment facilities that pull water from the Mott's Run Reservoir, the Ni River, and the Rappahannock River, which is the largest river in the local area, the other two being smaller tributaries that feed into it. The Rappahannock River is a significant body of water, providing the potable water for roughly a quarter-million people. Toward the coast the river sees mostly recreational and some light industrial use, and further upstream it is affected by many small to midsized agricultural operations that take place on the land adjacent to the river.

Located near Cowan, Pennsylvania, Conley Run is a tributary of Buffalo Creek that has experienced severe degradation due to agricultural activity. Specifically, the deposition of large amounts of animal wastes, pesticides, and fertilizers has resulted in significant eutrophication throughout the stream. Furthermore, bank degradation associated with the movement of livestock has caused the displacement of foreign sediments into stream habitats. These factors, among many others, have caused the lake to be considered “impaired” by PA-DEP. In response, the Buffalo Creek Watershed Alliance, the the Union County Conservation District, and the Department of Environmental Protection and Fish and Boat Commision have partnered in an effort to restore stream habitat and create a riparian buffer to protect the stream.

On August 19th 1955 the state of Connecticut was flood that filled many of the valleys causing approximately $185.5million in damages and 87 fatalities. The flood was caused by two back to back hurricanes rains from Hurricane Connie and Diane that totaled from 13 to 30 inches of rainfall within a 24 hour period. The Naugatuck River, the Farmington River, the Quinebaug River, Mad and Still Rivers were hit the hardest destroying 563 homes, the majority of which were located in lower Naugatuck Valley and Beacon Falls. Since this great flood many new ways to control this situation have been developed and put in place, such as many damns but by the Army Corps, to protect the surrounding towns.

Background (1 ¶): What is the Duck Creek Watershed? What problems is it facing? What is being done so far to remedy these problems? Who is working on this problem?

I am Dianaysis River; a girl who has a solid support system consisting of loving parents, an annoying yet reliable brother, and some of my closest friends. I’m girl who was born and raised in the beautiful city of Milwaukee. It always puzzled me why Milwaukee isn’t Wisconsin capitol, I must just have too much pride in my city. It is just a shame Milwaukee is not what it used to be. I remember when I was a child there was so much life in this city. It was safe, clean, it was a place many could call home.

At one point in the film, the narrator emphasizes that if the salmon do not come to the area where the bears are waiting for them then Sky “won’t have enough fat stored up to feed Scout and Amber for the next winter’s hibernation.” While the bears like Koda and other wildlife rely heavily on the salmon groups as a source of food, the salmon themselves are depending on water levels and other climatic effects in order to reach the areas they have spawned in for years. From this given scenario, viewers grasp that while salmon depend on what the climate gives them, other animals do as well. In studying ecological impacts, Camille Parmesan further explores these ideas between climate change and wildlife, reporting that not only have bears “suffered significant population declines,” but due to their boundaries, the bears were “declining both in numbers and in mean body weight.” The film’s example and Parmesan’s research solidifies the concept of climate change having control in changing animal habits.

Discuss the findings from your investigation. Your discussion should include how your specific data relates to the ecology and the science ideas of the organisms involved.

Campbell Rive is the third largest city on the island, and really acts as a gateway hub to northern Vancouver Island.

The population of trout is steadily declining due to increasing levels of productivity in trout lake habitats. In order for a trout to survive it requires a cold lake and the lake being well oxygenated, having a deeper lake is better for this. If the productivity or temperature of the lake changes this can be harmful to the trout population. It is predicted that in the future there will be a temperature increase of 1.8—4.0__C by 2100 (Whittington et al. 2015). This increase in temperature

In order to get a full understanding of stream health, all indicators should be individually weighted, as different indicators hold greater magnitude than others. Out of the seven indicators stated above the first three represent the predictor or x variables, while the later four represent the response or y variables. The x variables are indicators that directly affects the streams overall health, while falling outside the influence of the stream. The y variables are indicators of stream health that can are interconnected and ever-changing; these variables are influenced by the x variables. The x variables act as the independent, while the y variables act as the dependant because they are independent variables in themselves, but are guided and shaped by the results of the x variables.
