Major Natural System : Beach Dune

This leaves the sand dunes more susceptible to erosion causing blowouts and disrupting the succession of vegetation in the area. This has been a problem at Studland Bay in Dorset on the south coast of England. Persistent human leisure activities on the dunes has led to substantial erosion in some parts of these dunes which has meant that Management programs have had to been introduced by English Nature. Sand dunes help absorb the pounding of high waves and reduce overwash flooding in storms.

When going to the sand dunes of the Illinois Beach State Park, we wanted to test the effects of different environment on succession, ecosystem development. The problem was to find out if there is a succession (ecosystem development) of plant communities taking place. If the sand dune’s closer to the lake are newer than those further inland, then, I believe succession will take place because the newest dunes do not have rich enough soil to support more complex plants like trees and shrubs growing in the areas that have already gone through later stage succession. The data supported our hypothesis.

This investigation will be exploring whether the movement of pebbles, shingle, shells and other materials found on the beach have impacted on the shape and structure of Newhaven beach and Castlehead Cliff. One of the key processes this investigation will focus on is that of long shore drift caused by strong prevailing winds, prevailing wind is the direction from which the wind usually blows. Cliffs are made from mainly two materials, chalk which is at the bottom and sand and clay at the top. If cliffs are facing the direction of prevailing wind it may lead in high rates of cliff

There are 2 types of beaches. One is erosion dominant and the other is deposition

The Year 10 geography field trip was an insightful experience into the workings and functioning of metropolitan coastlines here in South Australia. The day consisted of visiting various beaches in Adelaide that were influenced by some form of hard or soft engineering techniques that changed the natural processes of the beaches. What was evident from this trip was how much these beaches have been changed to an extent where it is unlikely that they will ever go back to the way they were prior to human settlement.

Although it supports a number of different organisms, Nudgee Beach lacks many of the fundamentals that make up a healthy and successful ecosystem. The first indicator of this is from the lack of birds present in the area. Although it has been noted for terrestrial bird species – such as kingfishers, pelicans, ibis, egrets, jabiru, stilts and heron – and wading bird species – such as golden plovers, curlews, tattlers and godwits – to have been spotted at Nudgee Beach and surrounding areas in the past; after a day’s worth of extensive observation and research, it was found that the birds observed were limited to magpie, ibis, great knot and eastern curlew species. To intensify this factor, at the time by which this lack of species was recorded, Nudgee Beach was expected to have started seeing tens of thousands of birds arrive for the migratory season [21]. This blatant lack of bird species diversity and quantity may have been due to the lack of small organisms within the ecosystem. The restricted number of small organisms at Nudgee Beach is detrimental to the entire ecosystem as these organisms make up the bottom levels of the food web and provide higher-level organisms with adequate amounts of food to consume. The smaller organisms expected to be observed – including; crustacean, shell, mollusc, lizard, frog, fish, worm, arachnid and insect species – was limited to the infrequent observation of crustacean, shell,

At Wanda Beach, the tall trees and scrubs act as a windbreaker which further protects the sand formation. According to the field work results collected using the anemometer (see figure 3), the Aeolian processes at the front and the top of the primary dune is where the wind speed is highest. So it is important to plant plants such as the hairy spinifex to stabilise the sand due to its expansive root system and its ability to survive low water conditions.

tides. There are also many programs which help to ensure the stabilization of dunes, these include the planting of new vegetation to combat erosion, fencing and designated

If you have ever lived in proximity to coastal areas you may have seen coastline erosion first hand. The beaches you frequent during the summer may seem to be getting smaller and smaller every year. Why does your favorite beach seem to be disappearing? Coastal erosion is to blame. The waves, wind, tides and currents all play a part in the mechanism that is coastal erosion. When water and wind batter the shoreline sediments are carried out to sea and deposited on the sea floor or at other points along the coastline. This is called an erosional coastline. This erosion may be very apparent or seem to have happened overnight when it happens due to a large storm or extremely high tide.

The environment around us in Southwest Florida is beautiful, but also delicate. From the tall cabbage palms to the shortest saw palmetto, the foliage that surrounds us represents life in Southwest Florida. The environment in Florida is extremely fragile and steps need to be taken in order to preserve its beauty. The first settlers in Florida sacrificed their living conditions to be surrounded by snakes, bobcats, and bears. From their sacrifice, Americans were able to settle one of the most beautiful places in the United States. Now, Florida has been bulldozed down and is filled with gated communities and retirement centers. The Florida landscape has taken many hits throughout the years, but it still manages to grow up through the concrete and show what Florida used to look like. The fragile environment in South West Florida needs to be protected for future generations to enjoy.

Long Island is famous for its sandy ocean beaches. Between the barrier beach and the main coast is the Great South Bay. The beaches and dunes have very different characteristics. The sandy beach is the junction of land and ocean. The sandy beach consists of two zones, the swash zone and the drift line. The swash zone is the area of wet sand, caused by the incoming wave. The drift line is formed by the dead seaweed and other aquatic plants. Behind the sandy beach is the primary dune. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. In some cases secondary dunes form. These dunes are behind the primary dune and are therefor protected from the ocean. This provides the stability necessary for plant growth. Many time a maritime forests will form on secondary dunes.

Florida Uplands: From the northwest corner of the state, the Florida Uplands run about 275 miles west to east, along the northern edge of Florida Panhandle and then extends south

Orlando Florida is known worldwide for its entertainment facilities, notably Walt Disney World, Universal Theme Park and other attractions. This paper reports on Orlando's natural environment and ecology, which doesn't get the attention and publicity that the theme parks do, but in the end these natural world places are more vital to the well being of the humans and wildlife in that area of Central Florida.

9. What are the different types of shorelines? Describe each type briefly. There is a rocky coast, lowland beach and barrier island, as well as coral reef. A rocky coast describes the most common type of costal area. This is where there are vertical wave cut cliffs and horizontal bench cut cliffs. The erosion undermines the cliffs and sends the resulting debris into the ocean forming rough outcroppings. Beaches are not only the sand

The intertidal rocky shore of Caloundra Beach is inhabited by diverse range of biodiversity of animals and plants, many of which have developed high levels of adaptations throughout their existence. The very boundary of marine and terrestrial ecosystem, this environment is subjected to extremes of the physical environment such as temperature, desiccation, wave turbulence as well the ecological interactions that commonly occur in biotic communities (e.g. competition, predation). However Rocky intertidal shores are easily accessible by humans and provide an enjoyable opportunity for passive recreation and for science and environmental education as well.
