Indicative distribution
The areas shown in pink and/purple are the sub-regions where the species or community is known or predicted to occur. They may not occur thoughout the sub-region but may be restricted to certain areas.

Scientific name: Eucalyptus corticosa
Gazetted date:
30 Nov 2001
Profile last updated:
01 Aug 2024
Description
A tree to 20 m high with thick, fibrous-flaky to shortly fibrous, grey-brown to red-brown persistent bark on trunk and larger branches. The bark above the trunk and on smaller branches is smooth, grey to grey-brown and sheds in short ribbons. Adult leaves are narrow-lanceolate to lanceolate, to 12 cm x 2 cm, grey-green, dull, and the same colour on upper and lower surfaces. Flowers occur in groups of seven and fruit is to 6 mm in diameter, with raised disc and exserted valves. Flowering occurs January to April, however flowers have been observed in late May.
Distribution
Highly localised distribution restricted to just a few sites east of Rylstone in the NSW Central Tablelands, near Mount Coricudgy.
Habitat and ecology
- Occurs in sclerophyll woodland on shallow infertile soils on sandstone ridges associated with the upper reaches of the Cudgegong River. It may be locally frequent, and is often associated with Eucalyptus rossii.
- Fire tolerant and resprouts from epicormic buds after fire.

Threats
- Clearing has reduced the original pre-European extent of Central Tableland Sand-slope Scribbly Gum Woodland habitat in the Cudgegong Valley, resulting in the fragmentation and isolation of some stands.
- Low intensity grazing and frequent fires occurring within the woodland from neighbouring agricultural and private land. Grazing contributes to the degradation of habitat.
- Habitat degradation from tracks and trails dissecting remnant patches of the species habitat. Physical damage from roadside activities e.g. lopping, charring, and exposure to edge effects.
- Risk of extinction from stochastic events due to restricted distribution and low abundances; with predominantly adult trees and a few juveniles occurring in scattered distributions of small clusters or larger solitary paddock trees in cleared open areas. A lack of knowledge of mechanisms causing poor recruitment in all populations.
- Inappropriate fire regimes may prevent recruits from surviving fires if they are too frequent or inhibiting germination if they are too infrequent. The species is particularly sensitive to inappropriate fire regimes due to a current lack of recruitment in all populations.
- Insufficient understanding of species/community ecology
- Habitat loss and degradation due to clearing for agricultural activities and road maintenance activities.
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
9 priority actions
to help recover the Creswick Apple Box in New South Wales.
Activities to assist this species
- Protect areas of known and potential habitat from clearing.
- Implement sympathetic fire management within and in the vicinity of populations in order to ensure adequate recruitment and regeneration.
