3. The local community help plant the trees and take out the weeds on the dunes. they use the paths and educate tourists on the project

4. it allows the Macleay river to remain fresh water and allows people to build along the river and use it as a recreational area

5. the plants on the beach become larger and the bush thicker the further inland you go. On the incipent dune there are grasses and on the foredune you begin to get bushes and on the hind dune you begin to get trees.

6. the roots of the plants prevent the sand from flying away as well as providing a wind shield

7. cattle grazing on the dune destroyed all stabilizing vegetation

8. the removal of the vegetation means the sand can drift away and the dune would gradually be destroyed and the river would have now protection from the ocean

9. the groups involved in the project include; Macleay Shire council, Department of public works, Department of Lands and the Soil Conservation Service of NSW.

10. the steps involved are; creation of a foredune, planting grasses like spinifex and gradually planting larger species like banksia and samll gums

12. if you look at the maps you can see how if the wind was coming from the South the longshore drift would've pushed the sand up against the headland eventually silting over the opening.

13. a) the sand dunes are pretty much completely stabilised and are not blowing away thanks to the vegetation
b) the vegetation hold the dune in place allowing the fresh water ecosystem to be protected from the salt water and the waves
c) anyone who lives on the lake now no longer have to fear the possibility of wave erosion as well as keeping the spot nice and pretty helps the tourist industry

14. Do I do this one?
