2.2       Regional Ecosystem Mapping

The Regional Ecosystem Map for the locality indicates that the site supports areas of Remnant Regional
Ecosystems. Much of the subject site is mapped as an indiscernible combination (50:50) of Regional
Ecosystem 12.2.9 and 12.2.13 which are described as follows:

RE 12.2.9 - Banksia aemula low shrubby woodland. Mallee eucalypts sometimes present, e.g. Eucalyptus
latisinensis. Occurs on Quaternary coastal dunes and sand plains with deeply leached soils;

RE 12.2.13 - Open or dry heath. Characteristic shrubs include Leptospermum spp., Leucopogon spp.,
Ricinocarpos pinifolius, Strangea linearis, Brachyloma daphnoides, Persoonia virgata, Xanthorrhoea spp.,
Styphelia viridis, Monotoca scoparia, Woollsia pungens and stunted Allocasuarina littoralis. Occurs on
Quaternary coastal dunes and beaches. Sand plains. Major vegetation communities include 12.2.13a -
Closed heathland dominated by Leptospermum juniperinum, L. liversidgei, L. polygalifolia or Baeckea
frutescens, with emergent Melaleuca quinquenervia. Occurs on Quaternary coastal dunes and beaches.

Greater than 90% of the investigation area supports this vegetation. The predominant distribution
occurs to the southeast of Grass Tree Court. This community has a Vegetation Management Act 1999
conservation status listing as “Of Concern” and is afforded Environmental Protection status under the
Eastern Beaches Overlay (OM4.1), Noosa Shire Council.

Mapped remnant vegetation also occurs to the immediate west of the aforementioned community. This
area supports a combination (70:30) of Regional Ecosystem 12.2.15 and 12.2.12 which are described as
follows:

RE 12.2.15 - Coastal sedgeland with Baumea spp., Juncus spp. Lepironia articulata, Gahnia spp. and
Eleocharis spp. and associated water bodies. Occurs on Quaternary coastal dunes and beaches. Low part
of coastal landscape where water collects from both overland flow and infiltration from adjoining sand
dunes. Major vegetation communities include:

12.2.15a: Associated permanent water bodies. Occurs on Quaternary coastal dunes and beaches. Low
          part of coastal landscape where water collects from both overland flow and infiltration from
          adjoining sand dunes.
12.2.15b: Lepironia articulata closed-sedgeland. Occurs on Quaternary coastal dunes and beaches.
          Low part of coastal landscape where water collects from both overland flow and infiltration
          from adjoining sand dunes.
12.2.15c: Cladium procerum closed-sedgeland. Occurs on Quaternary coastal dunes and beaches. Low
          part of coastal landscape where water collects from both overland flow and infiltration from
          adjoining sand dunes.
12.2.15d: Baumea rubiginosa closed-sedgeland, with Cyclosorus interruptus and Blechnum indicum.
          Occurs on Quaternary coastal dunes and beaches. Low part of coastal landscape          where
          water collects from both overland flow and infiltration from adjoining sand dunes.
12.2.15e: Leersia hexandra closed-grassland. Occurs on Quaternary coastal dunes and beaches. Low
          part of coastal landscape where water collects from both overland flow and infiltration from
          adjoining sand dunes.

RE 12.2.12 - Closed or wet heath ± stunted emergent shrubs/low trees. Characteristic shrubs include
Banksia spp. (especially B. robur) Boronia falcifolia, Epacris spp., Baeckea frutescens, Schoenus
brevifolius, Leptospermum spp., Hakea actites, Melaleuca thymifolia, Xanthorrhoea fulva with Baloskion
spp. and Sporadanthus spp. in ground layer. Occurs on poorly drained Quaternary coastal dunes and
sand plains. Low part of sand mass coastal landscapes where water collects from both overland flow
and infiltration from adjoining sand dunes. Major vegetation communities include:

12.2.12a:      Empodisma minus, Baumea rubiginosa, Epacris microphylla closed-heathland with emergent
               low shrubs of Leptospermum liversidgei. Occurs on poorly drained Quaternary coastal dunes
