7 Thicket (Tall Heath) . Comprising a dense mix of taller 
shrubs (about 1.5 - 3.0 m) dominated by Dryandra, 
particularly D. armata and D. nobilis , but including some 
other tall Proteaceae species (eg. Adenanthos cygnorum 
and Hakea trifurcata) and occasionally interspersed 
mallees. These thickets are located on the flattened 
ridgeline. The soils are red-brown to grey-brown coarse 
clayey loams or sandy loams with abundant lateritic 
gravels, rocks and some exposed hardcap. 
8 Herbfield . Exposed or near-surface granite sheets with 
some residual surface soil or soil pockets frequently 
covered by Borya sphaerocephala, mosses and lichens, but 
including numerous annual herbs and some sedges. 
Generally abutting or surrounded by Allocasuarina 
woodland. 
9 Mallet Woodland . Dense pure stands of Eucalyptus 
astringens subsp astringens (about 10 to 20 m) with an 
almost absent understorey except for a few resilient 
shrubs and abundant bark litter. Soils are red-brown to 
brown coarse clay loams with numerous gravels. All 
occurrences in the reserve are on the ridgeline including 
one area adjacent to and on a lateritic breakaway slope. 
9a Mallet Woodland . This community, a variant of the 
above, comprises more open and generally taller (about 
15 to 25 m) stands of Eucalyptus astringens subsp 
astringens often interspersed with E. ivandoo or 
Allocasuarina huegeliana and with variable canopy cover 
ranging from open to mid dense. The open to mid dense 
understorey includes Acacia celastrifolia, A. pulchella, 
Nemcia obovala, Dryandra nobilis and many others. Soils 
are red-brown to grey-brown clayey loams containing 
numerous gravels with rocks/hardcap regularly 
occurring within this ridgeline community. 
10 Mallee Woodland . Consisting of various mallee 
species, but occasionally pure stands to 4 m high and 
sometimes with other tree species interspersed or with 
tall shrubs. In the western end of the reserve these 
mallees tend to be Eucalyptus aspersa, E. falcata, E. la tens 
and E. thamnoides subsp megista while in other areas 
mainly E. incrassata and E. pluricaulis subsp pluricaulis. 
This community is located either on the ridge or the 
adjacent upper slope areas where the soils are red-brown 
loams with gravels.. 
G Rehabilitated gravel pits . Old gravel extraction sites 
that have been deep ripped and allowed to regenerate 
naturally. At this stage, the flora comprises mainly 
pioneer species and limited occurrences of several weed 
species. 
Flora. 
A total of 323 vascular plant taxa (including 22 weed 
species) from 51 families was listed for Nature Reserve 
A21064 with dicots and shrub species being the 
predominant taxa for the reserve (Table 1). 
The most represented families were Myrtaceae (39), 
Proteaceae (29), Papilionaceae (26), Orchidaceae (26), 
Poaceae (20), total 'Liliaceae' (20), Asteraceae (17), 
Stylidaceae (17), Cyperaceae (16), and Goodeniaceae (12). 
Nine Poaceae and three Asteraceae species recorded are 
weeds. 
The genera with the greatest number of species were 
Stylidium (15), Eucalyptus (12), Acacia (10), Caladenia (9), 
Hakea (8), Lepidosperma (8), Dn/andra (7), Drosera (6) and 
Austrostipa, Leucopogon, Dampiera, Goodenia, Melaleuca, 
Davicsia and Petropliile with five species each. 
One declared rare species (Conostylis drummondii) and 
seven priority species (Dryandra rufistylis, Eucalyptus 
aspersa, E. latens, Leucopogon florulentus, L sp 
Dongolocking, Microcorys lenticularis and Thysanotus 
cymosus) were recorded for the reserve. 
Discussion 
Vegetation and habitat. 
The vegetation of the reserve is not unique because 
similar vegetation types or variants thereof can be found 
in other upland remnants in this region. Overall the 
vegetation of the reserve is relatively pristine and 
contains a wide representation of upland communities 
for its small size. This alone makes it quite special in
