Description

Dodonaea stenophylla is an erect shrub to 4 m high. Leaves are simple, erect and linear, 3-11cm long and 1-2.5mm wide. Flowers are usually in auxiliary few-flowered cymes with pedicels 2-15mm mm long. Capsules are 4-, rarely 3- winged, depressed-obovate in lateral views, 5-11mm long, 11-15mm wide with wings 3.5-8mm wide.

Distribution

Dodonaea stenophylla is known to be widespread across central Queensland and into the Northern Territory. Within NSW, the species has a highly restricted geographic distribution within the Bingara area. The species was considered extinct in NSW until being rediscovered in 1994 which was confirmed in 2010.

Habitat and ecology

In NSW, this species is found on very steep slopes on unconsolidated and loose stony metasedimentary soils on mid to upper slopes and crests on crests facing NE to NW between 400 and 600 m altitude. It was commonly found to occur within open Callitris woodlands which at times verged on Semi-evergreen Vine Thicket.

Threats

Loss, modification and fragmentation of habitat in areas outside NSW.
Grazing by domestic stock
Feral goats browsing on individual plants, inhibiting growth and reproduction.
Feral deer browsing on individual plants, inhibiting growth and reproduction.
Disturbance from road and track works from maintenance and road widening causing loss of plants as the species is commonly found on the roadside.
Inappropriate fire regime including too frequent fires causing populations to decline. Furthermore, there is an insufficient understanding of the appropriate timeframes between fires to allow seedlings to germinate and reach maturity to replenish the seedbank.
Weed invasion, in particular coolatai grass (Hyparrhenia hirta) causing a change in the structure of vegetation communities around populations. High weed cover also promotes fire in the landscape causing loss of plants.
Incomplete knowledge of the species' distribution and abundance across its range
Mixed feral browsers, including goats and deer grazing on juvenile and adult plants affecting plant survival.
Drought causing stress in plants limiting the species ability to withstand impacts from feral herbivore browsing.
