Geographic Range [top]

Range Description:Sporadically distributed in eastern Australia  from Blackdown Tableland in southeast Queensland, through the tablelands and slopes of eastern New South Wales and the far east of Victoria. It also occurs in western Victoria, Kangaroo Is. and Mount Lofty Range in southeastern South Australia as well as a limited area of eastern Tasmania. The extent of occurrence is considerably more than 20,000 km2.
Countries occurrence:
Australia (New South Wales, Queensland, South Australia, Tasmania, Victoria)

Population [top]

Population:May be locally dominant or in the subcanopy.
Current Population Trend:Stable
Additional data:
Continuing decline of mature individuals:No
Extreme fluctuations:NoPopulation severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Usually found in open woodland in montane areas but also on coastal heaths and in riparian areas.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: The termite and rot resistant wood has been locally used for fencing in some areas.

Threats [top]

Major Threat(s): Callitris rhomboidea has declined in some parts of its range due to conversion of land for agriculture and pastoralism, overgrazing and the effects of introduced weeds. It has also shown some susceptibility to Phytophthora cinnamomi in areas such as the western Grampians in Victoria (Weste and Kennedy 1997). The overall level of decline is insufficient to meet any of the thresholds for listing as threatened.
