Abstract
The ecology and distribution of threatened grass Arthraxon hispidus in north-eastern NSW was investigated to inform conservation management. Preferred habitat comprised high-moisture, low-canopy conditions, typically found within various native freshwater wetland communities, as well as within disturbed habitats. Mapping and modelling suggest the species is more common in north-eastern NSW than previously thought. Disturbances, such as burning, promoted germination and recruitment of the species, especially among dominant exotic terrestrial perennial weeds. The species showed some seedbank persistence, however, plant cover declined under drought conditions. Protection and restoration of native wetlands could conserve habitat for A. hispidus while promoting regional biodiversity.
