The problem of degraded rivers within an extreme urban environment is occurring in the vast majority of major cities in the United States. Restoration efforts have been attempted in a few cities, some successfully and some not. This report examines the section of the Schuylkill River that runs through Philadelphia as a case study in order to determine the most practical restoration of an urban riparian ecosystem by integration of ecological, recreational, and economical advantages. The four most practical solutions to revitalize the urban Schuylkill River are to: 1) take no action, 2) establish a nature reserve, 3) build a public park, or 4) construct a public business district.…
One way to ensure the ecosystems structure is not damaged is by ensuring that all the rules are followed in the park. The main reason why there is no wading in the water or fishing is preserve the life of the species in the water. The water levels are monitored daily to ensure the water flow is staying constant, and when a drought starts to show they monitor the water levels of the springs every few hours. Being that there is over 50 species of trees it is important to monitor them during the drought season as…
A huge amount of rock falls from one of the cracks, or steep slopes in the national park could make it hard for many animals to get to resources, or hunting grounds. Animals could be affected by a rockfall more so that humans because of this. If animals only know one way to get food or water, and they get cut off from that because of an event such as a rockfall, the population of animals in the area could die off. Whereas humans have plenty of other resources we can gather from to get our food and…
“The human history of the Yellowstone region goes back more than 11,000 years. From then until to the very recent past, many groups of Native Americans used the park as their homes, hunting grounds, and transportation routes. These traditional uses of Yellowstone lands continued until a little over 200 years ago when the first people of European descent found their way into the park. In 1872 a country that had not yet seen its first centennial, established Yellowstone as the first national park in the world. A new concept was born and with it a new way for people to preserve and protect the best of what they had for the benefit and enjoyment of future generations.” ("Yellowstone National Park Service", 2013) In the following paragraphs, the author will discuss the major structural and functional dynamics (processes) of that ecosystem including change over time, also, how humans may have affected biogeochemical cycles in that ecosystem, including impacts to the nitrogen, phosphorus, or carbon cycle. The author will also discuss how knowledge about that ecosystem’s structure and function can help or has helped to develop plans for its management and restoration plus the implication of species interactions in ecosystem management and restoration.…
An ecosystem is a complex set of relationships among the living resources, habitats, and residents of an area. Which includes plants, trees, animals, fish, birds, microorganisms, water, soil, and people ( ). The Patuxent Wildlife Research Center, in laurel, Md encompasses a type of ecosystem, which makes it a unique environment t visit. The Patuxent Wildlife ecosystem contains many plants, wildlife, and lakes. In this essay I will discuss the structural and functional dynamics of the Patuxents Wildlife Research Center ecosystem of Lake Allen at North…
* Forests help regulate the movement of water by pulling it from the soil and pumping it into the atmosphere (helps maintain climate)…
To understand the present state of the nation’s parks, and ultimately their entire future, it is crucial to first look back at the past. The first national park was Yellowstone National Park. This sprawling park contains such amazing geological and biological sites that it had been considered a national park long before it was ever officially named one. Its combination of diverse wildlife, and geologic features such as, waterfalls, canyons, geysers, and hot springs made it obvious to any who had experienced it, that this was a place that should be preserved just the way it was. That was why in 1872, President Ulysses S. Grant made it officially the world’s first national park. The only problem being, it was a completely unique creation, the first of its kind. This means that all ground that they covered would be new.…

We should be concerned with the extinction and try and preserve the biomes and ecosystems that are present. Over time the ecosystem and biomes have evolved changed in some form or fashion that will leave us in difference from this particular time now. It’s important to have something to be able to look back on for information and or instructions on how to change things that we as human may make a mistake and mess up.…
-A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants.…
Riparian sediments are fine in their ability to hold nutrients. When these two environmental factors come together, there is or can be a growth in a complex vegetative community. Surrounding riparian zones are typically grasslands and they get their source of water from the groundwater in riparian streams. The temperatures in riparian zones fluctuate and are dangerous for biotic life that depends on an acceptable temperature ranges for the vulnerable individuals in the habitat. The appropriate water temperature from riparian streams comes from the morphology that play a crucial role for maintaining that temperature.…
In the years since the wolf reintroduction, Yellowstone has become a premiere scientific laboratory for wilderness observation and ecosystem recovery. Scientists have come from around the world to watch the effect wild wolves have on the park. We have discovered that an ecological effect called the “trophic cascade” has taken over Yellowstone, with the wolves initiating a more natural ecosystem balance than has been seen in over sixty-five years.…
In summation, land and wildlife study and conservation remains an important issue. Ever growing numbers of people enjoy visiting wild parks, however, they must also remain aware of the true reason the parks exist. In addition to beauty, National Parks are priceless areas that provide the study of wildlife and the local environment in order to better understand how to protect them for future generations to enjoy.…
The ocean is one of, if not, the largest biome on earth. There are more than one million species of marine life. Covering over 70 percent of the Earth’s surface, the ocean is our planet’s largest habitat, containing 99 percent of the living space on the planet. This area holds the life of nearly 50 percent of all species on Earth. Like lakes, oceans are subdivided into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. The intertidal zone is the region along the shoreline between average low tide and average high tide. In other words, this region goes through cycles of submergence and exposure to air. Animals in this zone must be able to survive the extended periods of exposure. The pelagic zone includes all the open ocean water. The abyssal zone is the deep ocean water, between 6,560 and 19,685 feet deep. The benthic ocean includes the deep ocean bottom inhabited by organisms.…
Restoration Principle number three states that to restore biodiversity and function it is crucial to restore aspects of the hydrological regime such as seasonal flooding, water table levels, and streamflow as historically accurate as possible. The restoration strategy should focus on allowing the river to flow naturally and use natural stabilizing techniques for the bank such as planting vegetation. Other goals include reducing riverbed degradation from dikes and allowing sediment to flow naturally down the Mississippi. The floodplains should be reintroduced and the dams should allow more water and sediment to flow through naturally. If the restoration strategy focuses on these goals, then the lower Mississippi Delta ecosystems should be restored, resulting in improved habitats, increased sediment flow, and riverbed…
