Native Foresters 1.0 INTRODUCTION Native Foresters was commissioned by Long View Consulting Engineers to conduct a marine plant survey of the landward areas adjacent to the Catalina Jetty boathouse, which will be impacted by proposed upgrading works of the connecting concrete revetment wall and associated infrastructure. 1.1 Objectives of the report The objective of this report is to determine the extent of temporary and permanent impacts of proposed works on marine plants protected under the Fisheries Act 1994. 1.2 Site description The survey area encompasses the southern footprint of Lot 164 CP 907410 where it occurs on the southern bank of the Noosa River, within Apex Park (Lot 151 SP284457) at Gympie Terrace, Noosaville. The survey area covered a total area of 265m2, however part of this incorporates impervious areas such as pathways. The proposed impact area at the entrance to the jetty and boathouse includes an open maintained grass area with concrete pathways, a wooden boardwalk section, and a semi-paved access road, and adjacent sandy areas within the edge of the Noosa River. Refer to Figure 1. The majority of the site contains mown grass areas, with a semi-paved access road within the south-east section and a wooden boardwalk seating area along the western side of the revetment wall fronting the river. The majority of the revetment wall area has been stabilised with rock revetment on the western side of the jetty, with infiltration of water and erosion of soil and sandy substrate apparent, further exposing underlying rocks. The grass area directly south of the eastern failed revetment wall contains small sink-holes, with adjacent tree roots exposed at the eastern extent around the existing concrete river access ramp. Two large Coastal she oaks (Casuarina glauca), which have been impacted by erosion exposing the structural roots, occur at either end of the boundary of Lot 164 within Apex Park, with small beach areas and scattered trees further along the river bank to the east and west. State mapping of the survey area shows the central part of the survey area as occurring above Highest Astronomical Tide (HAT), with low lying tidally influenced areas on the eastern and western side of the jetty (Figure 1). Ground-truthing at the site found evidence of tidal influence across the survey area, and it is considered likely that the whole of Lot 164 is impacted tidally during coinciding high tide and high rainfall events. The survey area covers a section of maintained river bank with a constructed jetty and boathouse, with small beach areas and scattered trees further along the river bank to the east and west. The vegetation in the survey area consists primarily of introduced grasses, with small patches of Salt couch (Sporobolus virginicus) along the river bank. Two large Coastal she oaks (Casuarina glauca), which have also been impacted by erosion exposing the structural roots, occur at either end of the boundary of Lot 164 within Apex Park (Lot 151), managed by Noosa Council. Vegetation throughout the survey area is mapped as non-remnant. Catalina Jetty, Gympie Terrace, Noosaville – Marine Plant Assessment 4

Native Foresters
The survey area is mapped as occurring within a Coastal Management District, contains Storm
Tide Hazard Areas and Erosion Prone Areas, and adjoins the Noosa River which is mapped as a
declared fish habitat on the northern side of the river.
1.3 Proposed works
The revetment wall surrounding the Catalina Jetty and boathouse is proposed to be upgraded as
destabilisation from large rainfall events and tidal influence has occurred along the length of the
existing structure. Erosion and under-scouring of the sand substrate surrounding the revetment
wall have caused failure of the wall on the eastern side of the jetty, and infilling and erosion of
sand and material from underneath the western side of the wall. Erosion is also apparent to the
river banks directly to each side of the revetment wall structure. There are two proposed sections
of works along the revetment wall:
a) Removal of existing failed section of revetment wall and access ramp to the east of the
jetty, and construction of an upgraded revetment wall with conventional 20mm aggregate
backfill to the lot boundary (Lot 164 CP907410). Embankment retention and stabilization
at termination of the proposed revetment works shall be installed in consultation with
Council, using Council's nominated method as applied to the adjacent zones of riverbank
treatment.
b) Stabilisation and infiltration control of soil below the eroded section of revetment wall
directly south and to the west of the boathouse using cementitious injection grout.
A temporary holding and storage area for works has also been proposed for the grass and
pavement area at the southern extent of Lot 164, with site access from Gympie Terrace being
obtained from the existing semi-paved access roadway within the adjacent Apex Park.
The extent of the works impact area corridor is shown in Appendix A – Catalina Jetty Revetment,

2.0 METHODOLOGY
2.1 Desktop review
A desktop review was undertaken to assist in determining the site’s environmental values in
relation to protected marine plants. The review consisted of searches of government planning
instruments and databases, as well as relevant academic literature, and aerial imagery of the site.
Multiple mapping products and databases were utilised to determine species, ecosystems,
communities, and areas of conservation significance with potential relevance to the study area
(1-2km radius around central coordinates (Latitude -26.39772, Longitude 153.05997), or relevant
Lot on Plan of the site, dependent on database). Sources of information are listed below and
described in Appendix B.

2.2 Marine Protected Plants Survey
A detailed marine protected plant survey was conducted on the 27 th April 2023, which included
identification of marine plant specimens below and adjacent to the HAT within the survey area.
This survey area covered an approximate area of 265m2, all of which is deemed to be tidally
influenced and therefore subject to the requirements of the protected marine plants survey.
The definition of ‘marine plants’ and ‘dead marine wood’ contained in section 8 of the Fisheries
Act 1994 and in section 5.4 of the Department of Primary Industries and Fisheries Management
and protection of marine plants and other tidal fish habitats, Fish Habitat Management
Operational Policy (Couchman & Beumer, 2007) was used for the purposes of the survey.
‘Marine plant’ includes the following –
(a) A plant (a tidal plant) that usually grows on, or adjacent to, tidal land, whether it is living,
dead, standing or fallen;
(b) Material of a tidal plant, or other plant material on tidal land;
Catalina Jetty, Gympie Terrace, Noosaville – Marine Plant Assessment 7
Page 11
Native Foresters
(c) A plant, or material of a plant, prescribed under a regulation or management plan to be
a marine plant.
Marine plants include mangroves, Swamp she-oak with Salt couch understorey, seagrass,
samphires, saltbushes, Salt couch and saltmarsh plants, algae and other tidal plants that are
growing adjacent to the tidal zone, landward and seaward, above and below HAT, are
protected under the Fisheries Act 1994. All other native plants and plant material growing
below HAT are also protected under the Act.
‘Dead marine wood’ means a branch or trunk that is or was part of a marine plant. Plant material
on tidal land includes all non-native species unless listed under the Biosecurity Act 2014 as a
Restricted Invasive Plant (RIP).
The following methodology was used to conduct the marine plant survey:
• The survey area was projected into ArcGIS pro 3.0.2 along with QLD government spatial
data including vegetation management, waterways, elevation and cadastral layers and
exported to the Avenza maps application for viewing on an Ipad with inbuilt GPS. The
Queensland Government mapped HAT layer was sourced from QSpatial and projected
into ArcGIS for visualisation of areas above / below HAT. This was ground-truthed on site
by observing characteristics such as presence and absence of marine tolerant species
and the landform, and adjusted to the high-water mark to compensate for inconsistencies
in the data.
• The botanist surveyed the vegetation for marine plants designated under the Queensland
Fisheries Act 1994. All plants below HAT were considered ‘marine plants’. Above HAT,
plants were considered ‘marine plants’ if they were within/ or adjacent to a tidal area, and
species listed in the Fish Habitat Management Operational Policy (Appendix 1, Table 3)
(Couchman & Beumer, 2007) including mangroves, Melaleucas, Swamp she-oak with Salt
couch understorey, Salt couch, Samphire and Mangrove fern.
• The area of marine plants occurring above and below the estimated HAT was measured
by a vertical projection downwards of the living and attached plant material. This cover
equates to the projected foliage cover in the Fish Habitat Management Operational Policy
(Couchman & Beumer, 2007).
• The botanist recorded what percentage of the area occupied by each species or marine
plant community would be subject to temporary impacts (i.e., where marine plants were
considered likely to be able to recolonise within 5 years of disturbance) or permanent
impacts (i.e., where clearing required for proposed works would result in permanent loss
of marine plants).
• The maturity of mangroves and presence of pneumatophores was noted using the
following size classes: adults (>2m tall); saplings (<2m tall); seedlings (<0.5m tall).
• Survey results were imported into GIS pro 3.0.2 for analysis of species composition and
total areas of temporary and permanent impacts to marine plants from proposed works.
Impervious surfaces such as concrete pathways were excluded from the areas of impacts
to marine plants.

Native Foresters 3.0 RESULTS - MARINE PLANT IMPACT ASSESSMENT The vegetation within the works footprint at Catalina Jetty is all within tidally influenced areas and deemed as marine plants for this survey. The survey area is dominated by introduced grasses Blue couch (Digitaria didactyla) and Buffalo grass (Stenotaphrum secundatum) interspersed with a small amount of native Salt couch (Sporobolus virginicus) at the revetment wall and along the river bank. Native spurge groundcover (Chamaesyce drummondii) is also present in high density within the semi-paved access road area. Two Moreton Bay ash (Corymbia tessellaris) trees with median Diameter at Breast Height (DBH) of 205mm occur along the southern boundary of Lot 164 (Tree identification numbers 4 & 5, Figure 2), which will not be impacted from proposed works. Two large Swamp she oaks (Casuarina glauca), occur at the eastern and western boundary of Lot 164 within Apex Park, with their root systems extending into the proposed works area (Tree identification numbers 3 & 6, Figure 2). The root systems have also been impacted by erosion exposing some structural roots along the river bank (northern side of trees). The Tree Protection Zone (TPZ) and/or Structural Root Zone (SRZ) of these trees may be impacted by proposed works, and arborist assessment may be required to advise on management of these individuals, especially in relation to potential impacts from cementitious injection grout at the western tree (tree number 6). In relation to tree health, it is considered that additional future works may be required in the adjacent Apex Park to stabilise the structural root zone of these trees to ensure that they are not undermined, resulting in potential collapse of these trees into the river. Within the river bed one small plant of Dugong grass (Halophila ovalis) with 6 leaves occurs 1m north of the eastern revetment wall within approximately 40cm deep water. The remainder of the river bed area contains bare sand with a small amount of algae growth apparent on some of the submerged rocks and parts of the wall. Adjacent to proposed works along the Noosa River, Swamp she oak are growing below the HAT along the river bank, with Moreton Bay ash (Corymbia tessellaris) Small-fruited grey gum (Eucalyptus propinqua), and Fine-leaved red gum (Eucalyptus seeana) above the HAT on the riverbank. Total impacts to marine plants cover an area of 231.65m2 within the survey area. The areas of permanent disturbance to marine plants associated with revetment wall replacement and upgrade works include 13.2m2 within section 1 (eastern revetment wall), and 9.3m2 within section 2 (western revetment wall). The areas of temporary disturbance to marine plants associated with site access and a holding/ storage area for works include 207.5m2 within the southern section of the Lot and part of adjacent Lot 151, as well as to 1.65m2 within the river bed of section 1 & 2 where construction may temporarily disturb the sandy substrate and associated marine plants. The impacts to marine plants are summarised in Tables 1 and 2, and Figure 2. The location and distribution of marine plants is shown in Figure 3, with further information on trees present at site detailed in Appendix C.

4.0 SUMMARY AND RECOMMENDATIONS
The data collected during the marine plant survey of Catalina Jetty survey area indicates that
there is the potential for impacts to 231.65m2 of marine plants, which includes:
A total permanent area of 22.5m2 which includes:
▪ 11.2m2 of permanent impact to Swamp she oak roots, where material will be removed or
treated during revetment wall replacement and upgrade;
▪ 0.66m2 of permanent impact to Salt couch, where material will be removed during
revetment wall replacement and upgrade;
▪ 6.6m2 of permanent impact to Blue couch, where material will be removed during culvert
replacement;
▪ 3.828m2 of permanent impact to Buffalo grass, which will be removed during revetment
wall replacement and upgrade;
▪ 0.23m2 of permanent impact to Sea algae, where material will be removed during
revetment wall replacement and upgrade.
A total temporary area of 209.15m2 which includes:
▪ 0.3m2 of temporary impact to Dugong grass on the river bed, where material will be
impacted during revetment wall replacement;
▪ 0.15m2 of temporary impact to sea algae on the river bed, where material will be impacted
during revetment wall replacement and upgrade;
▪ 1.2m2 of temporary impact to dead marine wood on the river bank, where material will be
impacted during revetment wall replacement;
▪ 87.15m2 of temporary impact to Blue couch within Lot 164 and 151, where material will
be temporarily disturbed during use as an access road and storage site;
▪ 62.25m2 of temporary impact to Buffalo grass within Lot 164 and 151, where material will
be temporarily disturbed during use as an access road and storage site;
▪ 58.1m2 of temporary impact to Native spurge within Lot 164 and 151, where material will
be temporarily disturbed during use as an access road and storage site.
Care will be required during works to ensure that other marine plants within or adjacent to the
works footprint corridor are not disturbed, especially mature Swamp she oak directly adjacent to
the eastern and western extent of works within Apex Park (Lot 151). Consultation with a
professional Arborist (and in conjunction with Noosa Council), may be required to assess potential
risks to tree health from proposed works, and to assess future management options in relation to
ongoing erosion undermining the structural roots of the trees along the river bank. Temporary
impacts should be minimised to river bank and river bed areas containing marine plants within
the works corridor.
