These plant species are well suited to the region, perform well, are commercially available and do not have a tendency for weediness.
Vegetation should be planted in such a way to account for future growth. This ensures the roots and canopy of the mature vegetation remain outside the offset area.
This list is intended as a general guide, please consult your local native plant nursery for specific advice for your location. Mown grass should be directly above a sewer, drain or water main.

Additional protection for trees: Root Barriers
In addition to the required offset distances, Westernport Water recommends the use of root barriers. Correctly installed root barriers can help prevent or limit the impact of tree roots on surrounding infrastructure by reducing root growth beyond the barrier or diverting root growth away from the barrier. Please contact your local nursery for product and installation advice.
Other approvals
Tree planting and associated activities may need to comply with other regulations or legislation not administered by Westernport Water, e.g. Special Building Overlay or Land Subject to Inundation Overlay.
