Amended Noosa Project Restoration Plan V12_5

Please note, that in line with the ESP report, no impact to mangroves or seagrass as a result of the
works is expected at any of the proposed restoration sites.


3.1 Tewantin




The Tewantin Restoration Site is located along the southern shoreline of the Noosa River. The site lays
adjacent to Tewantin Park, more than 100m upstream of the Tewantin boat ramp.

A port channel marker is located seaward at the downstream end of the site. A Telstra-owned
submarine telecommunications cable bisects the site at the upstream end. The cable is relatively
accurately mapped but its exact position will be confirmed and mapped, by geographic survey, prior to
construction work commencing. Exclusions are imposed for the telecommunications cable. A small
beach intersects the fringe and has been excluded from the restoration footprint.

A narrow strip (5m wide canopy) of cotton wood (Hibiscus tiliaceus), interspersed with grey mangroves
(Avicennia marina) and river mangroves (Aegiceras corniculatum) occupy the shoreline fringe.
Mangroves are in moderate condition, growing on rock and gravel on an erosion prone bank. A public
walkway lies landwards of the fringing mangroves.

The proposed oyster reef patches would be placed primarily on bare sand and gravel (with dead oyster
shell) and on rocky rubble adjacent to marine plants in the intertidal zone. The patches will cover a total
area of 1326 m2 and be at least 10 m from seagrass and 2 m away from mangroves (including
pneumatophores) to prevent any direct damage to those marine plant assemblages.

As per Annex 1, ESP has confirmed that the oyster reef patches will be placed primarily on bare gravel
with dead oyster shell which makes up 42 percent of the 1326 m2 area covered by restoration patches.
