forest block contains the last remaining old-growth and high conservation
value jarrah-marri forest outside conservation reserves in the
south-eastern jarrah forest.
The 5840 ha block is in the Greater Kingston forest region, some
30 kilometres south-east of Bridgetown Intensive logging is scheduled
to begin before winter in the Warrup 06 compartment. Logging will
then follow in Warrup 08 compartment, east of compartment 06.
When the Greater Kingston National Park was being set up in 2004,
part of the Warrup forest block was left out of the Park despite
the strongest representations by Bridgetown conservation groups.
This was because CALM wanted access to the large volumes of high
quality timber in this block.
Much of the Warrup 06 compartment is only minimally disturbed,
being selection logged once only for prime jarrah in the 1940s,
and thus has high conservation value (HCV).
The forest throughout Warrup block is ecologically mature with
old growth characteristics. There are many tall, old jarrah and
marri trees with varying sized hollows that are needed by tree-dwelling
fauna such as the red-tailed black cockatoo and the ringtail possum.
Unlike regrowth areas this forest has diverse and mature midstorey
vegetation with dense thickets that provide high quality habitat
for foraging, and refuges for nesting and breeding of many mammal
and bird species. These species include uncommon, rare and threatened
mammals such as the woylie that are now greatly restricted in
their range in the south-west but still have populations in the
Greater Kingston forest region.
The river, stream and wetland ecosystems that occur in the undisturbed
mature Warrup forest provide important habitat for many animals.
Moist zones in these low rainfall forests also contain micro habitats
used by rare and little known moisture dependent Gondwanan invertebrates
and many other microorganisms that contribute significantly to
the health of forest ecosystems.
Warrups special values are not represented in the reserve
As well as important natural values, the Warrup forest also has
significant historical and cultural values.
Shelterwood logging in the nearby
and its adjacent forests contain 17 artefact sites listed on the
Aboriginal Sites Register. These show traditional occupation of
these forests by the Kaniyang people.These forests also have associations
with Aboriginal and European pastoral endeavour in the south-west
in the 1880s and early European settlement in the region in the
The forest in Warrup 06 compartment contains a surviving three
kilometre section of bush railway formation with a variety of
cultural features that illustrate the final phase of bush rail
operations of Millars timber company in the 1940/1950s.
Besides greatly increasing the risk of salinity and dieback, extensive
disturbance from roading and intensive logging will seriously
damage and disrupt the long-term biodiversity and environmental
integrity of these valuable forests, especially their fauna habitat
Surviving and potential unassessed cultural heritage sites and
their context may also be damaged or lost.
Given the uncertainties and threats from climate change to future
forest condition and health, Warrup forest must be left intact
and undisturbed for its significant natural and cultural values
and potential carbon storage role.
It must be protected from logging with its unwanted and unnatural
legacy: a diminished forest, depleted biodiversity and cultural
heritage and destructive, unnecessary waste of irreplaceable nature.
