Land use changes in Tasmania have been cited for a change in regional bird populations.
Large-bodied granivorous or carnivorous birds such as sulphur-crested cockatoos and ravens have increased while birds that forage among treetops and mid-story vegetation, including species unique to Tasmania, appear to have declined.
The results follow surveys in woodlands of the Midlands Biodiversity Hotspot; the focus of an ambitious ecological restoration program and Australia’s second-oldest agricultural landscape. Bird data were related to land-use change over the last 20 years to explore the current state of local bird communities and how they might have changed.
