Description:

The overall objective of the proposed research is the establishing of principles to guide the restoration ecology of disturbed ecosystems within the Swan Coastal Plain Region of southwest Western Australia, with a focus on restoring framework over-storey species.

The proposed research will aim to solve the problems that have hampered restoration in this particular ecosystem since its conception.

It has been postulated that soil compaction and drought stress are key contributors to restoration failure in the Swan Coastal Plain, but there is limited scientific data to support this theory.

Using ecophysiological techniques, this PhD thesis will define the underlying principles for plant responses to these two major environmental stresses and determine means to manipulate framework species, thus raising the success rate of restoration.
