The Slaty Red Gum is a medium sized member of the Myrtaceae family. It often grows to 18 m tall, although some have been recorded up to 30 m (Brooker & Kleinig 1999; Chippendale 1988). The bark is smooth and mottled white to slaty grey and sheds over the whole trunk in large plates or flakes. The juvenile leaves are oval in shape with a blue-green tinge and a whitish bloom. The buds and fruit are similarly coloured; with the fruits also being oval shaped and 7–10 mm long. The species grows in grassy woodland as well as dry eucalypt forest. It is found on deep and moderately fertile soils that are well-watered (NSW DECCW 2005dr).

The Slaty Red Gum is only found on the north coast of NSW in two separate districts. It is found near Casino where it is locally common and further south from Taree to Broke and west of Maitland (Johnson 1962a). It is found in two Natural Resource Management Regions: the Hunter/Central Rivers and the Northern Rivers regions. The species is only conserved in a flora reserve in the Bremer State Forest, south of Casino (DEWHA 2008og).

Slaty Red Gum is locally frequent, but sporadic (Bell 2004).

Since the discovery of the species in 1962, it has been observed in a variety of habitats:

  • shallow soils or stony hillsides, but not on poor sandstones (Johnson 1962a)
  • grassy woodlands on deep, moderately fertile and well watered soil (Harden 1991)
  • gentle slopes near drainage lines in alluvial and clayey soils (Chippendale 1988).

Habitat within the Hunter/Central Rivers Region

Within this region the Slaty Red Gum occurs within the following subsections; the Hunter, Karuah-Manning, Upper Hunter and Yengo sub-regions. The species is associated with the following vegetation classes (NSW DECCW 2005dr):

  • Hunter-Macleay Dry Sclerophyll Forests
  • Northern Gorge Dry Sclerophyll Forests
  • North Coast Dry Sclerophyll Forests
  • Sydney Sand Flats Dry Sclerophyll Forests
  • Western Slopes Grasslands
  • Coastal Valley Grassy Woodlands
  • Northern Hinterland Wet Sclerophyll Forests
  • North Coast Wet Sclerophyll Forests.

Habitat within the Northern Rivers Region

Within this region the Slaty Red Gum occurs within the following subsections; the Clarence Lowlands, Clarence Sandstones, Dalmorton, Rocky River Gorge, Stanthorpe Plateau, and Woodenbong sub-regions. The species is associated with the following vegetation classes (NSW DECCW 2005dr):

  • Clarence Dry Sclerophyll Forests
  • Northern Gorge Dry Sclerophyll Forests
  • Coastal Valley Grassy Woodlands.

There are three main threatening processes associated with the Slaty Red Gum (DEWHA 2008og):

  • clearing for agriculture and development
  • timber harvesting activities
  • lack of regeneration through grazing pressure.

The conservation advice given by the department (Threatened Species Scientific Committee 2008og) outlines a number of actions essential to the conservation of the Slaty Red Gum:

Research priorities

  • Design and implement a monitoring program.
  • Gather more precise data on population size, distribution, ecological requirements and the relative impacts of threatening processes.
  • Undertake survey work to locate additional populations.
  • Undertake seed germination trials to determine conditions for successful establishment of new populations.

Regional/Local priority actions

Habitat loss, disturbance and modification

  • Ensure proper monitoring of populations to identify key threats and determine the effectiveness of management actions.
  • Ensure agricultural activities and timber harvesting activities do not adversely impact Slaty Red Gum populations.
  • Control the removal of Slaty Red Gum for firewood or fencing material.

Trampling, Browsing or Grazing

  • Develop and implement a stock management program for travelling stock routes.
  • Modify grazing in known stands of Slaty Red Gum to enhance regeneration.

Fire

  • Develop and implement a fire management strategy that identifies the appropriate fire intensity and duration to encourage regeneration.
  • Provide population locations and details to fire services so that they may be included in fire risk management plans and mitigation practices.

Conservation Information

  • Raise awareness of the Slaty Red Gum within local communities.

Enable recovery of additional sites/populations

  • Undertake seed collection and investigate options for increasing plant numbers.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
