SCHEDULE
Littoral Rainforest and Coastal Vine Thickets of Eastern Australia
The ecological community represents a complex of rainforest and coastal vine thickets, including some that are deciduous, on the east coast of Australia. Typically, the ecological community occurs within two kilometres of the coast, including offshore islands, or adjacent to a large salt water body, such as an estuary and, thus, is influenced by the sea. It is naturally distributed as a series of disjunct and localised stands occurring on a range of landforms derived from coastal processes that can include dunes, headlands, seacliffs, offshore islands or other places influenced by the sea. As a result, the ecological community is not associated with a particular soil type and can occur on a variety of geological substrata.
The ecological community occurs from Princess Charlotte Bay, Cape York Peninsula to the Gippsland Lakes in Victoria as well as on offshore islands on the east coast. The latitudinal range where the ecological community occurs encompasses warm temperate, sub-tropical and tropical climate zones.
The ecological community is defined by habitat expressed in terms of structure, floristic composition and ecology in response to coastal processes. Whilst the ecological community’s canopy species are well adapted to coastal exposure (e.g. strong and persistent salt-laden winds and storm events), the canopy protects less tolerant plants in the understorey. The canopy height varies with the degree of exposure and can range from <1 to 25 m tall. Due to extreme exposure to salt laden winds, the canopy often demonstrates equal height. Highly exposed patches will display the effect of windshear in the canopy. In more sheltered sites, for example, around estuaries, wind shear may not be evident in the canopy.
The diversity of plants (particularly canopy species) generally declines in a north to south direction, i.e. with increasing latitude. However, species richness of adjacent patches may vary considerably within one latitudinal zone.
The key diagnostic characteristics of the ecological community are:
The ecological community occurs in the following IBRA bioregions: Cape York Peninsula, Wet Tropics, Central Mackay Coast, South Eastern Queensland, NSW North Coast, Sydney Basin and South East Corner.
Patches of the ecological community occur within two kilometres of the east coast, including offshore islands, or adjacent to a large body of salt water, such as an estuary, where they are subject to maritime influence.
The structure of the ecological community typically is a closed canopy of trees but can be patchy when in exposed situations and as a result of storm events. As a result, the canopy forms a mosaic due to canopy regeneration. Usually, several vegetation layers are present. However, where there is extreme exposure to salt laden winds, these distinct layers demonstrate equal height. Moreover, wind sheared canopy can be present on the frontal section leading to closed secondary canopies. Emergents may be present, for example, species from the genera Araucaria (northern bioregions only), Banksia or Eucalyptus. The ground stratum of the vegetation typically is very sparse.
The ecological community contains a range of plant life forms including trees, shrubs, vines, herbs, ferns and epiphytes. To the north, most plant species diversity is in the tree and shrub (i.e. canopy) layers rather than in the lower layer. The converse generally occurs from the Sydney Basin Bioregion southwards. Feather palms, fan palms and large leaved epiphytes are generally rare. Ground ferns and epiphytes are lower in diversity in littoral rainforests compared to most other rainforest types.
Plants with drought tolerant and succulent features are generally more common in littoral rainforest than in hinterland rainforest types. Canopy stem sizes also tend to be smaller compared to that in hinterland rainforest. Trunks rarely host mosses though lichens are usually common.
Whilst species can be regionally predictable, there may be considerable variation in the composition of individual stands of the ecological community within any given bioregion. Annexure A provides a list of plant species for each relevant bioregion.
The Littoral Rainforest and Coastal Vine Thickets of Eastern Australia ecological community comprises those patches that meet the key diagnostic characteristics (above) and the condition thresholds below.
Small patches can be resilient and viable, but the minimum size of a patch needs to be 0.1 ha; AND
The cover of transformer weed species (as identified in Annexure A) is 70% or less. Transformer weeds are highly invasive plants with the potential to seriously alter the structure and function of the ecological community. This threshold recognises the relative resilience and recoverability of the ecological community to invasion by weed species; AND
The patch must have:
o at least 25% of the native plant species diversity characteristic of this ecological community in that bioregion (Annexure A); OR
o at least 30% canopy cover of one rainforest canopy (either tree or shrub) species (Annexure A, excluding Banksia and Eucalyptus species that may be part of the ecological community).
Note that:
Where gaps in the canopy exist, they should be in the process of regenerating with the usual suite of rainforest gap species for the site (Annexure A). Where weed invasion is significant, natural regeneration of native gap species may be limited.
As species diversity diminishes from northern to southern latitudes, it is important to take into account the natural diversity of a patch in a particular bioregion when examining specific sites.

FLORA SPECIES OF LITTORAL RAINFOREST AND COASTAL VINE THICKETS OF EASTERN AUSTRALIA BY BIOREGION
Note 1: This ecological community is defined by habitat expressed in terms of structure, flora composition and ecology in response to coastal processes. Whilst species can be regionally predictable, there may be considerable variation in the composition of individual stands of the ecological community within any given bioregion. The diagnostic characteristics presented in the listing advice should be considered when determining the presence or absence of this ecological community.
Note 2: This flora list is not exhaustive. Additional rainforest species encountered when surveying a site need to be included when determining the condition thresholds. Species in this list may not always be exclusive to this ecological community.
