3. Noosa Project Restoration Plan V12

TNC Project Management Plan 2020

The TNC Project Management Plan was formally adopted by the project’s Technical Advisory Group
(TAG) and Noosa Shire Council in September 2020. The Plan, available on request, broadly scopes the
restoration project and includes:

    a. Risk Assessment
    b. Communications Plan
    c. Monitoring, Evaluation and Reporting (MER) Plan

1.8 Definitions

Restoration zone

·   An area of the estuary, with distinguishable physical and ecological characteristics in which specific
    restoration sites are selected.

Restoration site

·   A specific area of riverbed where restoration works are undertaken.
·   A restoration site is larger than the restoration footprint to allow for the expansion of the
    restoration footprint in the future.

Restoration footprint

·   The area of the rock and/or rock + shell composite substrate in direct contact with the riverbed
    within a restoration site.
·   The footprint comprises a series of oyster reef patches, which are the on-site placement of modular
    designs.
·   The footprint area is the sum of the area of oyster reef patches on a given restoration site, or across
    restoration sites.
·   The footprint area of a restoration site is less than the area of the restoration site in which they
    site.

Oyster reef patch

·   An area rock or rock + shell placed on a restoration site as the foundation for oyster ecosystem
    restoration, and which is readily discernible from all other oyster reef patches.
·   Oyster reef patches are placed in association with each other, to maximise ecological interaction
    (as a reef complex) and are placed on site to best match the profile and ecological character of a
    restoration site.
·   Oyster reef patches are separated to maximise water flow between and around each patch, to
    reduce sedimentation potential, reduce erosion potential (of the patch itself – undercutting, and
    shoreline – by refraction waves), and to not impede fish passage.
·   The number of oyster reef patches on a restoration site in a series may vary reflect the site
    characteristics.
·   The number of rows of oyster reef patches may vary to reflect the site characteristics, particularly
    bathymetry.
·   If more than one row of oyster reef patches is placed on a site, the rows of oyster reef patches are
    offset.
