Mulgoa Nature Reserve, New
South Wales
Mulgoa Natural Area, Penrith, New South
Wales
The Mulgoa Natural Area
contains an unusual and striking geological feature
of a 30m high cliff of the Mulgoa Laminite
(siltstone) Member of Ashfield Shale on the eastern
bank of Mulgoa Creek. This natural outcrop exposes
a sequence of the Wianamatta Group, including
Minchinbury Sandstone which is extensive but
infrequent in outcrop. The sequence is capped and
protected by Rickabys Creek Gravel of Tertiary
age.
The place features
Shale/Sandstone Transition Forest associated with
the transition between Wianamatta Group shale and
Hawkesbury Sandstone. This community is typically
species rich, with plant species characteristic of
both geological types, including some which are
restricted to the transition zone. The place also
contains several small but mostly undisturbed
catchments.
Vegetation cover over most of
the area is predominantly remnant or regenerating
woodlands. Significant remnants of Cumberland Plain
Woodlands, a nationally endangered ecological
community and endangered in NSW, occur within the
place. Various woodland types that occur and are
part of this Cumberland Plain Woodlands ecological
community are Shale Hills Woodland, Moist Shale
Woodland, Shale Plains Woodland and Alluvial
Woodland. Grey box-ironbark woodland, typical of
the shale woodland types is endemic to the
Cumberland Plain of the western Sydney region and
predominates throughout the place. The place also
contains Sydney Coastal River Flat Forest along
major water courses, the naturally restricted
Shale/Sandstone Transition Forest and Western
Sydney Dry Rainforest which are listed as
endangered ecological communities in
NSW.
Remnant vegetation along
Mulgoa Creek and its tributaries provides links
with the nearby Blue Mountains National Park. The
various vegetation types and landscapes, including
riparian corridors with Western Sydney Dry
Rainforest and Sydney Coastal River Flat Forest,
the shale cliff habitat and the restricted Moist
Shale Woodland, provide an important diversity of
habitats for native fauna and flora, particularly
woodland birds.
Dillwynia tenuifolia, which
is nationally vulnerable and vulnerable in NSW
occurs in the sandstone outcrop vegetation
community associated with the Ashfield Shale cliff
within the place. Acacia fimbriata, and Wurmbea
biglandulosa have particular regional significance
and are vulnerable in western Sydney. Twenty other
plant species that occur in the place are
vulnerable in western Sydney.
Mulgoa Natural Area includes
the archaeological remains of Regentville.
Regentville (1823-1869) was constructed for Sir
John Jamison (1776-1844) physician, landowner and
constitutional reformer who arrived on the First
Fleet. Regentville was known as the grandest and
most substantial house in the colony of NSW, and
was named in honour of George IV, the former Prince
Regent. Despite its ruinous state Regentville is an
important site as the place where Sir John Jamison
chose to have his mansion complex built and where
he established a major agricultural
enterprise.
The Regentville site is
historically significant as a rare example of the
site of probably the first wine estate to use the
terraced vineyard technique (c1830); one of the few
early wine estates where the vineyard terraces and,
though ruinous, the old winery can still be
located. The vineyards are important as one of the
earliest complete wine-producing enterprises
planned and implemented at the time ie. vineyards,
large winery/store, access road and circulation
system.
The place has associations
with Henry Kitchen (mansion design) and Sir Henry
Parkes (labourer at Regentville
1839-40).
The Regentville ruins and
surrounds is an area of substantial archaeological
deposit and archaeological potential. The site has
already yielded substantial archaeological evidence
of early 19th century development. It also contains
numerous plants likely to be the progeny of earlier
species. These plants are useful in maintaining an
appropriate character and setting for the
site.
The place is used for
educational purposes by geology and archaeology
students and also has excellent potential for
studying the comparison of sandstone and shale
vegetation communities.
