MU 13 — Rosewood / Brown Beech subtropical rainforest on the southern slopes of Barrington<br />
area<br />
Closed forests with a highly diverse canopy characterised by Dysoxylum fraserianum,<br />
Pennantia cunninghamii and Doryphora sassafras. Other common canopy species include<br />
Daphnandra species A, Dendrocnide excelsa, Sloanea australis, Baloghia inophylla, Polyosma<br />
cunninghamii, Caldcluvia paniculosa, Diospyros pentamera, Brachychiton acerifolius, Citronella<br />
moorei, Ficus coronata, Cryptocarya obovata, C. erythroxylon, C. glaucescens and Orites excelsus.<br />
A mid storey of smaller trees is commonly present and includes Alectryon subcinereus,<br />
Alangium villosum, Mischocarpus australis, Streblus brunonianus, Neolitsea dealbata, Syzygium<br />
australe, Diospyros australis, Claoxylon australe, Vesselowskya rubifolia and Acmena smithii.<br />
Various smaller shrubs may also be present in the understorey, such as Eupomatia laurina,<br />
Tasmannia insipida and Psychotria loniceroides. The ground layer is characteristically ferny,<br />
with common fern species including Pteris umbrosa, Adiantum formosum, Lastreopsis<br />
decomposita, Arthropteris tenella, Microsorum scandens, Lastreopsis acuminata, Diplazium<br />
assimile and Doodia aspera. In addition, various graminoids and forbs are also common in<br />
the ground layer, such as Lomandra spicata, Gymnostachys anceps and Dictymia brownii. No<br />
naturalised species were recorded in this community at more than 25% of sites.<br />
Within the study area this community is restricted to the Barrington Tops area at mid<br />
elevations.<br />
Littoral rainforests<br />
MU 14 — Tuckeroo / Coast Banksia littoral rainforest and coastal low open forest<br />
Open forest to low closed forest characterised by Cupaniopsis anacardioides and Banksia<br />
integrifolia, with other common canopy species, including Livistona australis, Endiandra sieberi,<br />
Polyscias elegans, Acmena smithii and Alphitonia excelsa. Various shrubs are common in the<br />
mid storey, including Breynia oblongifolia, Dodonaea triquetra, Glochidion ferdinandi, Notelaea<br />
longifolia, Pittosporum revolutum, P. undulatum, Acacia irrorata and A. longifolia. Numerous<br />
climbers are commonly also present in the mid and overstorey including Smilax australis, S.<br />
glyciphylla, Marsdenia rostrata, Pandorea pandorana, Cissus hypoglauca, C. antarctica, Stephania<br />
japonica and Kennedia rubicunda. The ground layer typically consists of Pteridium esculentum<br />
and graminoids, such as Lomandra longifolia and Dianella caerulea. Scattered forbs, such as<br />
Commelina cyanea and Viola hederacea, may also be common in the understorey. Naturalised<br />
species recorded at more than 25% of species in this community include Ehrharta erecta<br />
(Panic Veldtgrass, 29%), Lantana camara (Lantana, 71%) and Chrysanthemoides monilifera<br />
subsp. rotundata (Bitou Bush, 92%).<br />
Within the study area, this community occurs on coastal lowlands of the Lower North<br />
Coast and Central Coast on sands and sandstones. MU 14 is equivalent to the Endangered<br />
Ecological Community ‘Littoral Rainforest in the NSW North Coast, Sydney Basin and<br />
South East Corner Bioregions’ (DECC 2009).
