Part 3 Our study of the plants
Discuss the reasons why the distribution pattern you have identified occurs.
Use the environmental info we discussed at the beach (eg wind, salinity, how dry, etc), the profile diagram/site map and relevant adaptations of the plants.
Below is some reference material about the biology of the shore plants, use it to help with your discussion.

Task: to investigate the dunes and produce an illustrated report on the Tahuna sand dune ecosystem
Part 1 History
- How are beaches and dunes formed?
- What is the history of the Tahuna area? (include images)
- Where has the sand come from and how did it get there?
- How have the Rocks road seawall and the culvert affected the dunes?

Part 2 The future
- Read about and summarise the councils coast care plan

Part 3 Our study of the plants
- The task/data sheet (not term 4 class... use the data from a previous group)
- What plants are present and where on the dunes are they found? Does the plant community show zonation? Explain.
- How do the plants affect (and/or change) the dunes and the dune environment?
Discuss the reasons why the distribution pattern you have identified occurs.
Use the environmental info we discussed at the beach (eg wind, salinity, how dry, etc), the profile diagram/site map and relevant adaptations of the plants.
