Desktop Fauna Assessment
with steep cliffs, ledges, gorges, terraces, caves and large rock piles, often occurring
near waterholes (Creese, 2007). Competition for food resources with introduced and
abundant native herbivores (eg. Feral Goat and the Euro), predation from introduced
and native predators (eg. Feral Cat, Fox and Wedge-tailed Eagle) and habitat
degradation (through grazing, fire and the Feral Goat) have been implicated as
threatening processes limiting rock wallaby populations (Species Bank, 2009).
The Black-flanked Rock-wallaby was formerly widespread across the Wheatbelt
region occurring on many rocky hills and granite outcrops. The Black-flanked Rockwallaby
is known from Kokerbin Nature Reserve inhabiting rock crevices and caves
at Kokerbin Rock following its self-reintroduction from neighbouring populations
after having recovered in numbers from fox baiting.
Tammar Wallaby (Macropus eugenii) PRIORITY 5
The Tammar Wallaby is listed as Priority 5 by DEC. This species was formerly
distributed across much of south-western Australia but now occurs in a few scattered
populations including Dryandra and near Pingelly (DEC, 2009). The Tammar
Wallaby inhabits coastal scrub, heath, forest, mallee and woodland. This species has
been previously recorded north of Yoting and may persist in the region.
Quenda (Southern Brown Bandicoot) Isoodon obesulus PRIORITY 5
The Quenda is listed as Priority 5 by DEC and has declined over much of its range
including on the Swan Coastal Plain. The Southern Brown Bandicoot occurs in the
south-west of Western Australia north to Yanchep and Gingin, south to Albany and
east to Esperance. This species previously occurred north to Moore River and east
throughout the Wheatbelt but like many mammals in the region has undergone a large
range reduction (Maxwell et al. 1996). On the Swan Coastal Plain it is patchily
distributed, as a result of land clearance, habitat degradation and feral predators, and
often occurs in small and fragmented populations (DEC, 2008). It is commonly
associated with dense, low vegetation. This species is considered locally extinct in the
Kokerbin region.
Western Brush Wallaby (Macropus irma) PRIORITY 4
The Western Brush Wallaby is listed as Priority 4 by DEC. This species occurs in
south-western Australia, from Kalbarri to Cape Arid. The Western Brush Wallaby
formerly occurred over a much larger area however has suffered a large range
reduction and fragmentation of populations due to clearing for agriculture and
predation by introduced predators (DEC, 2008). The optimum habitat for the Western
Brush Wallaby is open forest or woodland, in which it favours open, seasonally wet
flats with low grasses and open, scrubby thickets (Strahan, 1995), and areas of dense
vegetation. It is also found in mallee and heathland (DEC, 2008). The Brush Wallaby
has been recorded in the Beverley area and occurs in reasonable numbers throughout
intact bushland west of Beverley (J. Turpin. Pers. obs.).
