Hy Brasil, Clareville low pitched horizontal roof. Hy Brasil which derives its name from the mythical Isle location of the Garden of Eden, has magnificent views of the Tasman Sea to the east and Pittwater to the west. Pedestrian access to the house is via a narrow winding pathway up a steep slope through large sandstone boulders. Native trees have been retained around the house and supplemented by plantings of ornamental exotics, notably sweet gum (Liquidambar styraciflua), pampas grass (Cortaderia sp.), fruit salad plant (Monstera deliciosa), tree ferns (Cyathea sp.), giant bird-of-paradise flower (Strelitzia nicolai) and azaleas (Rhododendron indicum cv.s).

Plant tolerance to herbivory Erb "et al." 2009). However, the importance of this mechanism to tolerance is not well studied and it is unknown how much it contributes to tolerance since stored reserves mostly consist of carbon resources, whereas tissue damage causes a loss of carbon, nitrogen and other nutrients (Tiffin 2000). This form of tolerance relies on constitutive mechanisms, such as morphology, at the time of damage, unlike the induced mechanisms mentioned above. Plant architecture includes roots to shoots ratios, stem number, stem rigidity and plant vasculature (Marquis 1996, Tiffin 2000). A high roots to shoots ratio will allow plants to better absorb
