2019-01-14 General Committee Agenda - Attachment 3 to Item 2 - Monitoring of Noosa River Oyster Reefs Nov 2018

Monitoring criteria 1- Oyster restoration unit location stability
Performance objective
Oyster restoration units remain within the designated Resource Allocation Areas.

Monitoring method and frequency
Visually inspect the stability of oyster reef units and record the precise GPS position (± cm
scale), and size of each unit (following international best practice: Baggett et al. 2015). Use
GIS software to contrast the position, footprint, size and area of oyster reef restoration units
between monitoring events and assess any potential movement.

Frequency: Every 6 months for a minimum of three years. Additional monitoring will be
conducted within 2 weeks of substantial rainfall events (i.e. events that exceed 50-year
Average Rainfall Intervals).

Was the performance objective met?
No units moved outside of the RAA area, and all repairable reefs were repaired. Therefore,
all aspects of this performance objective were met, and no further action is necessary.

Supporting Evidence
No oyster restoration units moved beyond the RAA areas, and no units moved more than 1
m during either monitoring event (Table 3). Maps of each of the sites (Figures 5 to 18) are
provided below to support this lack of movement of bags. High-resolution maps and csv files
of the locations of the reefs at all three survey points (following installation, and at 6 and 12
month monitoring events) are available from USC upon request.
