Five various sites were visited to help compile a suitable management plan for the protection and conservation of NSI. The five habitats observed were One Mile Beach, Myora Springs, Main Beach, 18 Mile Swamp and Brown Lake. At One Mile Beach, seagrass quadrates were observed and information on the organisms observed were recorded. Myora Springs was visited to investigate mangrove habitat and was again observed for organisms. Sand dunes of Main Beach were studied with a dune transect being constructed and the location of different organisms were recorded. At 18 Mile Swamp, water tests were completed and collections of organisms recorded to show the health of the swamp. The final site was Brown Lake where further water tests were completed and organisms observed to compare against 18 Mile Swamp. ...read more.

Middle

The dunes have been vegetated, with more tolerant plants at the frontal dunes and less tolerant and larger plants at the rear dunes. Low creeping plants, like Spinifex and Goat's Foot inhabit the frontal dunes. This is because they are the only plants that can survive the extreme conditions of strong winds, salt spray etc. Gradually, plants like the Coastal Wattle and Banksia are found as they are short trees or shrubs and are protected in the swales of dunes. At the back of the dunes are Coastal Teatree and Casuarina's, which can tolerate the conditions this far back from the beach. They protect the island from strong winds. Wallabies and kangaroos, particularly grey kangaroos, visit the dunes for food. Other animals present include many insects and birds. These animals all visit for food, usually flowers and fruit but sometimes to feed one each other. Other animals cannot survive the conditions or are not found on the island.

They have olive brown upper parts with greenish yellow edges on their tails and feathers. They live in inland open forests, mangroves and usually in bayside areas or along watercourses. Brown Honeyeaters feed on insects and nectar and are found Australia-wide (Queensland Museum).

Conclusion

The location of the bay and islands in relation to Brisbane has had an impact on what can and has been done to protect its existence. Its importance to people both locals and indigenous as well as a diverse range of organisms was recognised to help form a plan that will suit all needs. Five different habitats on the North Stradbroke Island, most importantly Myora Conservation Park, were investigated to observe the different organisms found in the area. The Management Plan that was developed from the investigation will provide for the ongoing change in the Moreton Bay Marine Park management. 9.0 Bibliography Association of Societies for Growing Australian Plants (ASGAP).

Adult species have tough shells that offer protection from abrading factors and any near vibration causes the shell muscles to contract vigorously, clamping the organism to the substratum.
