The Vertebrate Fauna of Jenolan Karst Conservation Reserve: Final

GANG-GANG COCKATOO CALLOCEPHALON FIMBRIATUM
EPBC Act: Not Listed TSC Act: Vulnerable Priority in Area: Low
44
Occurrence in the Survey Area
Common resident. The gang-gang cockatoo is common within
JKCR and the reserve has large amounts of suitable habitat. It
was recorded numerous times during the current survey program
and is regularly observed by JKCR staff and visitors. During the
current survey it was observed throughout the full extent of the
reserve, including around Kanangra Walls Road and within the
Jenolan River Valley. Nesting has not been recorded within
JKCR, however there are a large number of mature trees with
suitable hollows. Driscoll (1977) found the gang-gang cockatoo
to be common in summer and uncommon in winter in the nearby
Jenolan SF.
Regional Conservation Significance

Metropolitan Special Areas and Kanangra-Boyd NP (DECC
2007). Within the region, taller forests at higher altitudes (such as
at JKCR and the Boyd Plateau) are important breeding habitat,
while forests in the Avon, Cordeaux and Cataract catchments are
lower altitude, non-breeding habitat. Habitat modelling within the
Greater Southern Sydney Region (DECC 2007) shows that
nearly three quarters of the high-quality habitat in this region is
within conservation reserves. This modelling also indicates that
this species has not been significantly impacted by land clearing
in the past. This study concluded that the population within the Region remains secure and is unlikely
to suffer significant declines under current land management practices. Given the small size of JKCR
and how well reserved habitat is for this species within the region, JKCR does not contribute greatly to
the overall conservation of the species. However, if trees where breeding occurs are recorded in the
future, they should be given special consideration and protection.
Threats in the Survey Area
Loss of hollow-bearing trees. Infection by Psittacine Circoviral (beak and feather) Disease and
competition with feral honey bees for hollows.
Management Considerations
Protection of hollow-bearing trees will benefit this
cockatoo as it requires these for nesting.
Staff are encouraged to report breeding sites and
lodge records in the Atlas of NSW Wildlife.
