Biology Mangrove Assessment
Preliminary Biology Assessment task 2013
A Local Ecosystem
Mangrove Swamp
Cassandra Mandelik

Introduction:
A mangrove is a tree, shrub, palm or ground fern, generally exceeding the height of one and a half metres. They normally grow above mean (average) sea level in intertidal zones of marine coastal environments as well as estuarine margins. A mangrove also refers to the tidal habitat comprising of such trees and shrubs.
Australian mangrove systems are highly effecting by human presence and, thus can have a negative impact on the local ecosystem.
Australian mangroves, although they may not seem like much, play a vital role, and are an extremely important ecosystem. Mangroves, or intertidal forests are able to prevent erosion and stabilize sediment because of their ‘breathing roots’, as well as this they also filter run-off from the land to keep the water of other more commercialized placed clear. These are just a few reason of why the mangrove ecosystem is of importance so we are able to maintain the biotic features that a present.
The purpose of the investigation is to estimate population and distribution of mangroves, and nippers as well as recording salinity and temperatures of the water in this ecosystem.
Human impacts will also be investigated, as it has a drastic effect on
Method:
1. Measure abiotic features including salinity, temperature and dissolved oxygen. This can be done using a datalogger with a temperature and a salinity probe attached and an oxygen meter. Record salinity, temperature and dissolved oxygen at three separate sites in the mangrove ecosystem.
Focusing on one of the three sites, record the temperature over the course of 10 hours. 2. Analyze the flow over energy and matter in a mangrove swamp.

1. Estimate the size of a plant and animal population.
Plant- To estimate the population of the mangrove tree, two methods are used. First being a transect. A transect is performed by measuring a line (20 metres

    River runoff from the land: Cane farmers in northern Queensland have had to reverse the cycle of the wetlands so that the water leaves the land quickly, in order for their cane crops to survive. The problem with the water leaving quickly, though, is that it drags the topsoil and various other harmful agricultural chemicals with it. That dirty water then filters into the river catchments that feed the Great Barrier Reef. This water turns into mud, algae and bacteria that settle on the living coral organisms. It then smothers the animal and eventually kills it.…

    Fresh water coming from Big Cypress Swamp combines with the Salt water in the Gulf of Mexico to create conditions that allow an amazing variety of life to flourish in features such as oyster bars, mangrove islands, tidal mud flats, and seagrass beds. While tidal mud flats and sea grass beds are important features the most prominent are the Oyster bars and Mangrove Islands. The Oyster bars and Mangroves are crucial in creating and continuing to develop the islands and characteristics that make up this region. Oyster Bars are formed by quartz sand carried by the current and deposited in deeper water parallel to the shore and eventually builds until it reaches the surface. If the conditions are right oysters colonize the sand deposits and the combination of oysters and sand create an oyster bar. Oyster bars gather nutrients by forming at right angles to tidal currents in order to catch nutrients from the incoming currents. Smaller branches form on the Oyster Bars and floating red mangrove seeds take hold in the sediments. Eventually multiple mangroves are caught and grow on the Oyster bar forming an island of roots and leaves. Overtime the mangroves arching prop roots will catch more sediment and the island will continue to develop eventually cutting off nutrients to the Oyster bar by restricting the currents that bring nutrients to the oysters. These structures help protect the region during storms, prevent erosion, and create Habitats for birds and fish. This is why more than 300 species of bird at some point are residents of the region as well as manatees and bottle-nose…

    We then checked the areas checked by the quadrats in 17 random areas on the map determined by a random number generator and counted how many of the 5x5 quadrat’s squares contained mangroves and recorded a percentage cover, giving us an estimated percentage cover of mangroves over all of Towra Point. 17 different areas were randomly picked out in our results, and by calculating the percentage cover of each individual point, adding them all together and then dividing by the amount of places we checked, we got an average percentage cover over Towra Point of 70.4% (Table 6) . Towra Point’s Nature Reserve is approximately 603.7 ha, or 6.037 km2. Using our average percentage cover of Towra Point of approximately 70.4%, we can now deduct that the average mangrove covering over all of Towra Point is 425 ha, or 4.25km2. (NSW Government, 2010)…

    They can be found stretched across costal northern Australia. The average soil PH level at Myora Springs was eight which is consistent with the ideal conditions for the Red Mangroves. These type of mangroves form extensive, often pure stands around the shores of shallow bays. Preferring soft, well drained muddy soils. In North Queensland, Red mangroves are able to grow up to ten metres high, however it is most common to see five metre high trees; most likely because of the lower and sparser human population and density towards the coastlines. A main feature of this species is their stout, a large arching prop of roots that contain numerous lenticels (air pores) that support the main trunk and enable to tree to live. Red mangroves have adapted to their salient ecosystem by tolerating salt. They eliminate salt from their roots as water is occupied. Excess salt is then stored in the leaves and the tree sheds these leaves later on. Although the Grey mangrove can withstand much higher salt concentrations, both species lived side by side at Myora Springs. This is because the average soil PH level was eight, which is not high enough to stop the red mangrove from…

    The Madden’s Creek ecosystem is located at the beginning of George’s River and is found 60km south west of Sydney at an elevation of 350 meters above sea level. About 45% of the catchment contains large tracts of natural bush land. It is home to many species of flora and fauna creating a wide range of biodiversity that interlink and affect each other significantly. In this ecosystem there is a mixture of rural and recreational land uses which all have a significant impact on the biophysical interactions in the area.…

    A fragile environment is one which is easy to disrupt, and once disrupted, difficult to restore. An example of this kind of environment is the Sundarbans; the largest single block of mangrove swamp in the world, covering 10,000 km² from the coasts of West Bengal to Bangladesh. The mangrove swamps are sensitive to a number of factors, including temperature, salinity and sea level, where small changes may be able to cause huge impacts on the overall health and effectiveness of the swamps to protect the coastline and the 300,000 livelihoods that depend on it.…

    Over time, reef management strategies have been introduced to help with the preservation and conservation of the reef, these strategies include traditional and contemporary management. Traditional management was when the Aboriginal people had complete control over the land, the indigenous people’s management included great admiration for the land, treating it with respect and using only justifiable amounts of food and materials. This was a sustainable and successful management strategy used to conserve and preserve the GBR. Contemporary management included reef exploitation, un-sustainable usage of materials, disregard for pollution and un-policed fishing which led the GBR to be at risk (GENETIC DIVERSITY, UTILITY VALUE, INTRINSIC VALUE AND HERITAGE VALUE AS ALL REASONS FOR THE PROTECTION OF THE GBR)…

    We have heard of the Columbine shooting, where in the spring of 1999 in Littleton, Colorado over a dozen people where killed and many others were wounded at the hands of two students. Or even more recently, we heard about the Virginia Tech massacre where a single student killed thirty-two people and wounded over twenty more. University of Texas, California State University, San Diego State University, the list of school violence is long and heart-breaking. Students and teachers have lost their lives by the dozens to gunmen that carried a grudge for some reason or another. These are extreme cases, for sure, and there is without a doubt a need for discipline in schools every where. However, zero-tolerance policies are not the answer to school discipline unless they can be reformed to have fewer gray areas and kept from being too strict, be less disruptive to the education process and allow teachers to keep their voices, and figure out how to correct claims of racial discrimination, regardless of claims that they are effective.…
