Scientific name: Eucalyptus canobolensis
Profile last updated:
17 Sep 2019
Description
Tree 8-12 m high, with bark smooth to base, shedding in ribbons. Juvenile leaves opposite, round, grey-green. Adult leaves lance-shaped, mostly 10-18 cm long, 1.5-3.5 cm wide, dull green or grey-green. Flowerheads 3-flowered, with a distinctly flattened stalk. Buds egg-shaped, 5-9 mm long. Fruit cup-shaped, 5-9 mm long, 6-8 mm diameter.
Distribution
Known only from Mt Canobolas near Orange. Found chiefly between 1100-1300m, but can occur down to 1000m and above 1300m. The species predominantly occurs in the Mt Canobolas State Recreation Area.
Habitat and ecology
- The landform consists of undulating low to steep hills. Soils are shallow skeletal sands and loams on steep slopes. Vegetation is a sub-alpine woodland.
- Other trees co-occurring with Eucalyptus canobolensis include Eucalyptus pauciflora, Eucalyptus dalrympleana, Eucalyptus viminalis, Eucalyptus dives and Eucalyptus saxicola. Understorey species include Poa sieberiana and Cassinia arctuata.
- Flowering period is listed as January to March. Seed is dispersed locally by wind, and there is no dormancy mechanism.
- It has been observed that apparent juveniles of Eucalyptus canobolensis appear to have regenerated more than once from previous fire events and have developed a small but noticeable lignotuber.
- The species is common in all parts of Mt Canobolas State Recreation Area, with mixed aged stands comprising seedlings, juveniles and adults.

Threats
- Blackberry infestations impede regeneration.
- Invasion of Pinus radiata seedlings from adjacent State Forests.
- Forestry operations (impinging on populations in Glenwood and Canobolas State Forests).
- Fire management (may be a threat in some circumstances; repeated fires may limit recruitment and cause mortality).
- Global warming and associated climate change (likely to result in a contraction to higher altitudes and possibly extinction in the wild). Other than ensuring there is germplasm in storage there is little that can be done to ameliorate this threat.
- High risk of extinction due to restricted distribution.

Activities to assist this species
- Ensure fire management is sympathetic to the required fire regime of this species to ensure adequate recruitment and regeneration.
- Ensure populations are buffered from forestry activities.
- Control blackberry and Pinus escapees outside forestry areas.
- Monitor population with particular reference to climate change impacts (relative to altitude).
