MU 181 — Broad-leaved Paperbark / Swamp Mahogany / Swamp Oak / Saw Sedge swamp forest
Open swamp forests characterised by an overstorey dominated by Melaleuca quinquenervia,
often in association with Eucalyptus robusta and Livistona australis. The understorey is
typically shrubby and includes M. linariifolia and Glochidion ferdinandi, along with climbers
such as Parsonsia straminea. The understorey is dominated by sedges and other graminoids,
including Gahnia clarkei, Ischaemum australe, Hypolepis muelleri, Baumea rubiginosa, B. juncea
and Lomandra longifolia. Common grass species include Hemarthria uncinata, Imperata
cylindrica and Entolasia marginata. Commonly recorded naturalised species included
Lantana camara (Lantana, 36%) and Ageratina adenophora (Crofton Weed, 28%).
Within the study area, this community occurs on coastal floodplains and poorly drained
lowlands of the Central Coast, mainly on muds and sands. This community is of particular
regional conservation significance as it relates to the Endangered Ecological Community
‘Swamp sclerophyll forest on coastal floodplains of the NSW North Coast; Sydney Basin
and South East Corner bioregions’ (DECC 2009).
MU 182 — Swamp Mahogany / Melaleuca linariifolia swamp forest of coastal lowlands
Open swamp forests with an overstorey dominated by Eucalyptus robusta and commonly
including Melaleuca linariifolia and Callistemon salignus. Common understorey shrubs
include Glochidion ferdinandi, Acacia longifolia and Polyscias sambucifolia, with the climber
Parsonsia straminea also common. The ground layer typically consists of a range of grasses,
including Entolasia marginata, Imperata cylindrica and Oplismenus imbecillis, along with
graminoids, including Gahnia clarkei and Lomandra longifolia. The only naturalised species
recorded at more than 25% of sites in this community was Lantana camara (Lantana, 35%).
This community is distributed within the study area in poorly drained sites on coastal
lowlands of the Central Coast and Lower North Coast. MU 182 is of particular regional
conservation significance as it relates to the Endangered Ecological Community ‘Swamp
sclerophyll forest on coastal floodplains of the NSW North Coast; Sydney Basin and South
East Corner bioregions’ (DECC 2009).
MU 183 — Paperbarks / Woollybutt swamp forest on the Central Coast
Open swamp forests with an overstorey characterised by Eucalyptus longifolia and with a
dense mid storey of tall shrubs dominated by paperbarks, including Melaleuca linariifolia,
M. sieberi, M. ericifolia and M. nodosa. A range of smaller shrubs is also common in the
understorey, including Pultenaea villosa, Leptospermum juniperinum, Acacia longifolia,
Melaleuca thymifolia and the grass-tree Xanthorrhoea fulva. The climber Parsonsia straminea
is also common. The ground layer is typically dominated by sedges and other graminoids
and grasses, commonly including Schoenus brevifolius, Chorizandra cymbaria, Gahnia
clarkei, Lomandra longifolia, Entolasia stricta, Hemarthria uncinata and Pseudoraphis paradoxa.
Common forbs include Gonocarpus tetragynus and Centella asiatica. No naturalised species
were recorded at more than 25% of sites in this community.
Within the study area, this community occurs on sands and sandstones on poorly drained
sites on coastal lowlands of the Central Coast. MU 183 is of particular regional conservation
significance as it relates to the Endangered Ecological Community ‘Swamp sclerophyll
forest on coastal floodplains of the NSW North Coast; Sydney Basin and South East Corner
bioregions’ (DECC 2009).
