Year 11 Biology River Mangrove Study Introduction Mangroves are woody trees and shrubs with a thick, exposed network of roots that grow down from the branches and into the water and sediment. All mangroves are found on the intertidal zones between ocean and the land. When the sediment accumulate little wave occurs, the saline depend on the frequency. Some of the indirect impacts are the sediment runoff and also including chemical runoff, global warming is one of main effects of the mangrove ecosystem. In Tannum there are various types of mangroves. Such as the river and grey mangroves located at south tree and wild cattle in both Tannum sands and Boyne Island along the Boyne River. Leaves are around 7cm long gland that secret salt, the…show more content…
The most common abiotic factors Aim The aim of the river study at both Tannum sands wild cattle and south tree Boyne Island was to undertake and investigate and collect data on the abiotic and biotic contributions to the mangrove ecosystem and to analyse the human impacts, regarding both the animal and plants distribution and abundance. Hypothesis It is predicted that the distribution and the abundance of both the animals and plants of the mangroves ecosystem would differ depending on the locations and the effects of the abiotic factors. Apparatus - 1 x Anemometer ( to calculate the speed of wind) - 1 x Thermometer (to measure the temperature of the air and water) - 1 refractometer - 1 moisture sensor probe ( measure the temperature of the soil) - 1xQuadrats 1m by 1m - 1xBuilder string - 1xSpirit level - 1xGum boots - 1xPlastic bags (to collect samples) - 1xGloves (for safety precautions) - 1xLight calculator - 1xUniversal indicator (to measure both the ph. of water and the ph. of soil) - 1xHumidity thermometer (to calculate the particles In the air and it’s humidity) - X1 compass Method First of all we located the animals and the plants abundance surrounding the mangroves ecosystem, to determine the population within each site. The materials were then gathered to commence the sampling for the abiotic factors. The measurements of the distribution of all organisms were measured first including the abiotic factors. A 14 metre long transect was made along
