Scientific name: Allocasuarina inophloia - endangered population

Conservation status in NSW: Endangered Population

Commonwealth status: Not listed

Gazetted date: 16 Nov 2012

Description

Stringybark She-Oak is a small dioecious tree, 3 to 10 metres tall with drooping or ascending branchlets. Bark is very ribbony-fibrous. Woody cones are 10-20mm long and 9-12mm in diameter on a stem 3-8mm long.

Distribution

Stringybark She-Oak occurs in northern NSW, southern Queensland and far north Queensland. In NSW the species is known from the Torrington-Emmaville, Yetman and Clarence Valley areas. The Clarence Valley population is disjunct form other populations. It occurs at Kungala, south of Grafton, approximately 150 km to the east of the closest known population at Torrington. It is estimated that there are less than 1,500 individuals in the population confined to an area of approximately 4 square kilometres.

Habitat and ecology

The Clarence Valley population occurs on a narrow sandstone ridge in grassy dry schlerophyll woodland.
Clarence Valley plants are 3 to 5 metres in height and many are multistemmed.
The species is known to resprout after fire and drought.
A seedbank is maintained in the canopy.

Threats

Quarry establishment, dumping of overburden and related vehicle movement in known habitat.
Inappropriate fire regimes.
Drought, including the potential implications it has on fire management.
Weeds competing with the endangered population and altering its habitat.
Inappropriate fire regimes (high severity) including risk from uncontrolled fires, arson or hazard reduction burning particularly on private property and commercial forestry land. Appropriate fire (e.g. no more than annually) can stimulate recruitment, but too frequent fire can deplete the lignotuber and destroy the seed bank and eliminate adults
Risk of local extinction due to small population size, inbreeding and geographic isolation.
Disturbance to critical ridge-top habitat and removal of Allocasuarina inophloia individuals due to sandstone quarrying activities.
Uncertainty of future land management practices on private land, including potential development for quarry extension and residential subdivision.
Trampling and grazing of young plants by domestic livestock (e.g. cattle) in close proximity to the population
Forestry operations degrading habitat and removing trees.
Fragmentation of habitat for residential development, extractive industries (e.g. open-cut coalmining and clearing for construction of mining infrastructure) and agriculture.

Recovery strategies

A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.

Activities to assist this species

Protect the population and it's habitat from clearing and negotiate long term protection measures.
Manage the population's fire regime to ensure viability (allowing for the potential effects drought may have on the appropriateness of the regime).
Continue to survey for the species in potential habitat within Clarence Valley LGA.
Undertake weed control works within known habitat.
Install measures to restrict vehicle movement to formed tracks.
Monitor population dynamics and threats.
Map population boundaries to identify areas to prevent disturbance from mining activities.
