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
and sand plains. Low part of sand mass coastal landscapes where water collects from both
overland flow and infiltration from adjoining sand dunes.

12.2.12b: Xanthorrhoea fulva wet heathland. 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.

Except for a small pocket located within the north-western corner, this association occurs beyond the
western boundary of the investigation area. This community has a Vegetation Management Act 1999
conservation status listing as “Not of Concern” but is awarded Environmental Protection under the
Eastern Beaches Overlay (OM4.1), Noosa Shire Council.

The balance of the investigation area is currently mapped as non-remnant vegetation. These areas
represent parcels of land immediately associated with Grass Tree Court and established infrastructure.

23 Vegetation Community Descriptions
Within the investigation area five distinct vegetation communities were identified. These are as follows:

Community 1 — Open/Dry Heath on Coastal Dunes

This community dominates the central and southern portions of the site and is comprised of an
indiscernible combination of vegetation types characteristic of Regional Ecosystems 12.2.9 and 12.2.13
(PLATE 1).

A representative list of flora species is contained in Appendix C.

The community is relatively devoid of non-indigenous flora (weeds), with most notable incursion
occurring within the northern extent of the community, where considerable clearing of vegetation has
occurred, and along most edges, including internal trails. Representation of all strata was recorded and
the community is regarded as relatively intact and would most likely satisfy the criterion for remnant
status. This concurs with current EPA mapping of the investigation area

The northern extent also appears to have undergone successive high intensity, unrestricted fire regimes
At the time of assessment the community was found to be devoid of non-indigenous flora and in the
initial stages of recovery with marked and diverse recruitment of characteristic species. Given the
opportunity to fully recover this area would satisfy the criterion of remnant status.
