Scientific name: Eucalyptus oresbia
Gazetted date:
15 Mar 2002
Profile last updated:
02 Dec 2021
Description
A tall tree to 30 m with smooth white, yellow or cream bark, which sheds in long ribbons. Its juvenile leaves are glossy green. The older leaves are narrower and dark green, 9.5 - 18 cm long and 1 - 2 cm wide. The gumnuts are hemispherical, 4.5 - 8 mm long and wide, and grow in groups of seven. The species' taxonomy is currently under consideration.
Distribution
Restricted to an area between Nundle and Hanging Rock in the southern New England Tablelands, with a disjunct population north of Murrurundi. Two small populations have recently been identified in Ben Hall's Gap National Park and near Dungowan Dam. Specimens tentatively identified as E. oresbia have been found in disjunct locations along the Liverpool Range.
Habitat and ecology
- Found at altitudes between 800 and 1100 m in very steep valleys and deeply incised creeklines with primarily south to southwest exposure (i.e. warm yet moist).
- Two large and two small subpopulations are known to exist, with some outlying individuals.
- Replaced by Eucalyptus pauciflora, E. elliptica and E. melliodora in less rocky habitat.
- Seedlings more commonly observed in disturbed areas and rare elsewhere.
- Age structure suggests populations are largely regrowth after disturbance from mining, forestry and road construction during the past century (data collected by J.T. Hunter and L. M. Copeland)
Regional distribution and habitat

Threats
- Clearing and fragmentation of habitat for agriculture and pine plantations.
- Frequent fire.
- Browsing and trampling by domestic stock.
- Timber harvesting.
- Destruction and disturbance of habitat for road-works.
- Risk of extinction because populations are small.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
24 priority actions
to help recover the Small-fruited Mountain Gum in New South Wales.
Activities to assist this species
- Support local Landcare groups.
- Protect areas of known habitat from frequent fire.
- Practice sustainable grazing in areas of habitat and protect regenerating trees from grazing stock.
- Identify roadside populations and protect during road-works.
- Protect known populations and areas of potential habitat from clearing and development.
- Protect known populations from timber harvesting activities.
- Expand and reconnect isolated populations in areas of appropriate habitat where recent declines are suspected.
- Regenerate and protect disturbed areas of habitat (e.g. bordering Pinus plantations).
- Monitor the spread of Pinus into E. oresbia habitat and control if needed.
