Abstract: Provision of permanent water in Australia’s rangeland regions and the subsequent effects of grazing in these habitats have altered the composition and condition of arid zone bird communities. Some species have expanded their geographic range, mainly those that are water-dependent and benefit from disturbances. In contrast, certain species that are water-independent and are sensitive to disturbance have declined throughout much of their former range. Little is known about the direct causes for these declines or what factors are driving arid zone bird assemblages. This research investigates the effects of artificial watering points and other resources on bird assemblages in the southeast Australian rangelands. This research is being carried out at the University of Ballarat’s arid zone research property, “Nanya Station”. Bird surveys and habitat assessments have been conducted at each of forty sites (ranging from 100 m to 6 km from AWPs) on the property to investigate relationships between birds and environmental variables. Contrary to expectation, preliminary results indicate that there is no relationship between distance to AWPs and bird assemblages. Further research will investigate whether other habitat variables (i.e. vegetation composition and/or structure) have an effect over the composition of rangeland avifauna.
