This ecosystem occurs throughout most of the site on the higher ground,
including the area marked as without remnant vegetation on the RE maps. It
consists of a canopy of 10-20m height, with a cover of 10-70%. The forest is
mature, with stem diameters at breast height generally varying from 20-50cm,
with some trees reaching to 70cm diameter.

The dominant tree species are Scribbly Gum (E.racemosa) and Pink Bloodwood
(Corymbia intermedia), with Angophora woodsiana occurring as a sub-dominant
in many areas. Occasional other species observed include Smooth-barked
Apple (Angophora leiocarpa), Brush Box (Lophostemon confertus), Swamp
Mahogany (L.suaveolens), Paperbarked Teatree (Melaleuca quinquenervia), and.
Blue Gum (E.tereticornis). Cypress (Callitris columeliaris) occurs as a sparse
sub-canopy tree along the western boundary, on the lower slopes of the south-
eastern boundary, and as a relatively dense sub-canopy around the central
heath and sedgeland.

The shrub layer is very variable, with a relatively dense shrub layer of 3-4m
height and 10-30% cover in the central area, and more open areas in the east
and west. Taller species included Hickory Wattle (Acacia aulacocarpa), Early-
flowering Black Wattle (Acacia leiocalyx), Coast Banksia (Banksia integrifolia),
Cheese Tree (Glochidion sumatranum), Red Ash (Alphitonia excelsa), Narrow-
leaved Geebung (Persoonia virgata), and Broad-leaved Geebung (P.cornifolia).
Smaller species include Heaths such as Epacris pulcheila, Leucopogon pimeleoides,
Guinea Flower (Hibbertia vestita), Blue Tongue (Melastoma malabathricum subsp.
malabathricum), Grevillea leiophylla, Prickly Moses (Acacia ulicifolia), and
Candlesticks (B.collina).

The ground layer is moderately open, with a cover of 30-70%, consisting of
grasses and other herbs. Grasses include species such as Kangaroo Grass
(Themeda triandra), Three Awns (Aristida spp.), Cockatoo Grass (Alloteropsis
semialata), Wanderrie Grass (Eriachne pallescens). Other herbs include species
such as Lobelia membranacea, White Root (L.purpurascens), Riceflower (Pimelia
linifolia), Pithy Swordsedge (Lepidosperma longitudinale), Caustis blakei, and
Bracken (Pteridium esculentum).

Vines are sparse, and largely confined to the ground layer. Species include
Snake Vine (Stephania japonica), Scrambling Lily (Geitenoplestum cymosum), and
Guinea Flower (Hibbertia scandens).

This ecosystem is equivalent to RE 12.9-10.4. Its status under the VM Act is
“not of concern”.

e Ecosystem 2: Paperbarked Teatree (Melaleuca quinquenervia) open forest and
woodland (RE 12.2.7)

This ecosystem occurs in small patches along the southern and eastern
boundary, while also fringing the central heath and sedgeland. The stand
along the eastern boundary has previously been (erroneously) mapped as RE
12.9-10.4 (ie Ecosystem 1, as described above).
