7.8 Dune Revegetation at Stuarts Point Questions

1. The Stuarts Point is the area where the sand dunes are.
2.

3. The  sand dune ecosystem by all working together to achieve the goal of re vegetating the Stuart's Point sand dune. They help by volunteering to plant and take care of the plants growing there and also can help by staying away from the dunes to allow re vegetation to continue without disturbing it.


4. The sand dune area is very important to the people of Stuarts point as much of the areas fishing and tourism industry is located within the vicinity of the dune. Another reason it is important as there are many expensive waterfront luxury home lining the area. 


5. The sand dunes have few section to them in which the plants were planted in. The first section is for primary species such as grasses and creepers. The second section is for secondary species such as shrubs and short-lived trees. 


6. Vegetation is so important for making sand dunes because the plant roots dig into the sand and actually fixes the sand. It makes  the sand to be locked in place by the plants and will not blow away.


7. The cattle grazing on the sand dune made the fragile vegetation to be destroyed. It was either stepped on or eaten plants which were very young and very venerable other things such as the cows.


8.The changes that would of cause after the cattle grazing would of been a open sand dune on which there would be no vegetation. The sand would of been exposed which was easily moved by the wind. Deposition would of been heavily used to transport the unprotected sand dune.


9.The groups involved in the rehabilitation were the Stuarts Point Progress Association, the Soil Conservation Service of New South Wales, the local Stuarts Point community, Department of land, Department of Public Works and the Macaulay Shire Council.


10.On top of this a dune-forming fence was constructed. It was then stabilized with coastal spinifex and marram grass. The second stage involved planting trees along the riverbank to stabilize the western margin of the area. They then planted native seedlings in the area between the fore dune and the riverbank. Then fast growing wattle were planted then coastal tertiary species were planted.


12. The geographical process that would of caused the river mouth to silt up is longshore transportation as well as deposition. 


13. 
a. The stabilization of the sand dunes was a great success.

b.The Macleay River ecosystem was protected as many animals had homes again after the revegetation but the noxious Bitou bush is taking over the area and will soon take over the whole dune.

c. This has benefited groups from the community as the fishing and tourism industry has been protected and helps this community in many ways.
