Wollemi National Park and southern Central Coast
Very low woodlands characterised by Eucalyptus multicaulis and occasionally including
other eucalypt species such as E. bensonii, Angophora bakeri and Corymbia eximia. The
understorey is typically densely shrubby and may be dominated by Baeckea brevifolia. Other
common shrub species include Allocasuarina nana, A. distyla, both occasionally abundant,
as well as Petrophile pulchella, Zieria laevigata and Isopogon anemonifolius. The ground layer
typically consists of various graminoids, including Schoenus imberbis, Lomandra obliqua, L.
glauca and Patersonia sericea; scattered grasses, such as Eragrostis brownii; and forbs, such as
Actinotus helianthi. No naturalised species were recorded at more than 25% of sites in this
community.
This community is distributed within the study area on ridgetops of ranges of the western
Blue Mountains at mid elevations on sandstones. MU 131 may have particular regional
conservation significance as it is the only community in this study to include records of the
rare shrub Epacris muelleri and the rare forb Velleia perfoliata.
