Scientific name: Eucalyptus cannonii
Profile last updated:
11 Jun 2019
Description
Usually occurs as a tree 10 – 15 m high with persistent, stringy bark. Leaves are lance-shaped, 9 – 15 cm long and 1. 5– 2.5 cm wide. Buds and bud stems are angular, and fruits are generally greater than 10 mm diameter, often with a distinct rim around the middle. Can be distinguished from E. macrorhyncha, a closely related species that may grow in similar habitat, by the angular buds and usually larger fruit with a medial rim and shorter pedicels. Hybrids between the two species are common in some places where they co-exist. Hybrids may be distinguished in the field on the basis of fruit diameter, lack of prominence of the medial rim and reduced angularity of buds.
Distribution
The Capertee Stringybark is predominantly restricted to the central tablelands and slopes of NSW between the Golden Highway in the north, and the Mitchell Highway in the south. The species' distribution is bounded from east of Bathurst, to Wallerwang near Lithgow, north along the western edge of Wollemi National Park and north-west to Mudgee; isolated occurrences are known from a short way north of Goulburn River National Park between Dunedoo and Merriwa. Within this area the species is often locally frequent.
Habitat and ecology
- Produces white flowers from January to April. The seed is spread by wind, generally in close proximity (within 30 m) to the parent plant; no dormancy mechanism.
- Capertee Stringybark can be locally abundant.
- Associated eucalypt species are diverse: Eucalyptus viminalis, Eucalyptus mannifera, Eucalyptus polyanthemos, Eucalyptus rossii, Eucalyptus blakelyi, Eucalyptus oblonga, Eucalyptus sparsifolia, Eucalyptus bridgesiana, Eucalyptus dalrympleana, Eucalyptus melliodora, Eucalyptus dives and Angophora floribunda.
- Hybridises with other stringybarks, in particular Eucalyptus macrorhyncha. At some locations where E. cannonii and E. macrorhyncha occur together no intermediates are found while at others hybrids are prevalent.
- Mature trees survive hot fires, resprouting from epicormic buds; however, frequent fires may kill seedlings and weaken mature trees.
- Capertee Stringybark has a broad altitudinal range, from around 450m to 1,050m. Within this range, the species appears to tolerate most situations except the valley floors.

Threats
- Habitat loss through landuse, including coal mining.
- Inappropriate fire regimes (specifically, too frequent fire) may reduce the vigour of mature trees and kills seedlings.
- Disturbance of roadside populations during road maintenance and upgrading.
- Exploitation for firewood and timber.
- Misidentification of Capertee Stringybark for Red Stringybark, and difficulties arising from intergrading stands of both species.
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
10 priority actions
to help recover the Capertee Stringybark in New South Wales.
Activities to assist this species
- Discourage firewood collection of this species.
- Protect remnants by fencing to prevent stock access.
- Protect areas of known and potential habitat from clearing.
- Restore habitat by replanting with plants raised from locally-collected seed.
- Investigate appropriate fire intervals for the species.
- Where road or infrastructure maintenance activities are planned in potential habitat, thorough surveys should be conducted and appropriate protection measures should be implemented if the species is present.
- Encourage mining proponents and determining authorities to avoid populations of this species.
