Dog Beach Sand Nourishment Project: Marine Plant Monitoring Plan                                          2
Monitoring Plan




2        Monitoring Plan
         This Monitoring Plan (the plan) details procedures to assess long term impacts on marine plants and
         fisheries resources associated with the construction and operation of sand nourishment works at
         Dog Beach.

         The plan will be maintained for a period of 3 years after completion of the works unless corrective
         actions are implemented.

         The plan provides the following elements:

         • Scope: activities and locations the plan applies to

         • Objectives: purpose of the monitoring plan

         • Responsibilities and obligations for monitoring and evaluation

         • Qualifications: mandatory qualifications for persons undertaking monitoring and evaluation

         • Timing: sets the frequency and intervals for monitoring events

         • Monitoring: monitoring procedures to be implemented post-construction including measures of
           vegetation cover and composition; ground/substrate/tidal conditions

         • Evaluation and Adaptive Management: procedures to evaluate monitoring results and implement
           adaptive measures

         • Corrective actions: procedures to implement restoration and/or offsets

         • Reporting: requirements for monitoring and evaluation reporting.

2.1      Scope
         Figure 2-1 shows the concept design for the proposed works in relation to marine plant communities.

         The dune woodland adjacent to the proposed sand nourishment area comprises terrestrial
         vegetation, sits above Highest Astronomical Tide and is not considered to support direct fisheries
         values. However, the foredune supports sparse Cynodon dactylon and Melaleuca quinquenervia,
         which can be considered marine plants under the Fish Habitat Management Operational Policy. The
         proposed sand nourishment fronting the dune will be placed to avoid vegetation and will not directly
         impact on living marine plants within the foreshore.

         The sand plug and sand nourishment at the eastern end of Dog Beach will occur directly adjacent to
         Avicennia marina, Excoecaria agallocha, Sporobolus virginicus and Sesuvium portulacastrum
         marine plants. Based on the concept design for the proposed works it is anticipated there will be no
         direct impacts to marine plants within this area.

         Fallen, dead trees on Dog Beach occur on tidal land and are considered marine plants for the
         purposes of the Fisheries Act 1994. The fallen trunks will be smothered during sand nourishment
         resulting in the permanent removal of approximately 244.2m2 of marine plants.
