North Stradbroke Island Research Paper
North Stradbroke Island is an island that is located within Moreton Bay in the Australian state of Queensland. The island is approximately thirty seven kilometres long and eleven kilometres wide. The island spans 27,520 hectares and of that only 445 hectares had been declared National Park. The highest peak is Mt Hargrave sand dune around 229 meters and the average rainfall is about 1803 mm per year. The rain does percolate through the sand into the islands water table. Underground water supplies are extensive; so much so that large amounts of water flow have literally formed the swamps on the island.
North Stradbroke Island has been formed by large quantities of sand which have their origin in the rocks of the Great Dividing Range which became …show more content…
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
