The only mangroves within proximity of the works are at the south-eastem end of the wall at the end of the Noosa River Spit
(Figure 6). The wall terminates adjacent to the mangroves, but works are to be undertaken in such a way that no mangroves
are to be interfered with as part of the works.

Due to the high rate of erosion there are a number of large dead trees along the length of the foreshore (Figure 7). These
are typically well-established trees. The number of trees is unknown, but they cover an area of approximately 7700m2.
These trees are classified as marine plants as they are within the tidal zone. It will be necessary to remove these trees to
allow for construction.

Where excavation is taking place, the full tree should be removed [although this may need to be done progressively during
excavation] to prevent blockages of the dredge pipeline and ensure that organics are not used to fill the container or sharp
sections remain where they could potentially result in damage to the containers. In other areas [i.e. where nourishment is
taking place or within work areas], trees may be trimmed at the required depth [approx 0.3m below surface], sufficient to
allow for access without damage to equipment.
