Tracking wader diversity and abundance
Migratory shorebirds make up around 5% of Australia’s species of birds and while around 18 species are considered resident or endemic to Australia, another 37 generally migrate each year along the East Asian-Australasian Flyway (EAAF).
Shorebirds or “waders” are birds commonly found on coastal shores, including beaches, rocky shores, mudflats, tidal wetlands and lagoons meaning the Noosa River estuary is the perfect location for visiting shorebirds.
The Noosa Integrated Catchment Association released a shorebird report in 2020 titled An analysis of migratory and resident shorebird diversity and abundance in the Noosa River estuary 2005 – 2019. It is the first known longitudinal survey of shorebirds in the Noosa River estuary.
151 surveys were conducted over a 14-year period between October 2005 to October 2019 with funding and technical support provided by the Noosa Shire Council under the Community Environment Grants Program 2019. The program is still running to this day.
Why tracking is important
The Noosa River estuary is one of around 150 sites located throughout Australia that comprise the National Shorebird Monitoring Program, coordinated by BirdLife Australia. The aim of the program is to understand and detect national population trends and discover what is driving population changes.
The report was designed to understand the long-term trends in shorebird biodiversity and abundance in the Noosa River estuary and for comparison against trends observed in other areas of Australia and across the EAAF.
Records were maintained for all species of birds observed within the survey area including shorebirds, water birds, wading birds, gulls, terns and raptors.
Some of the resident and migratory shorebirds found in the Noosa River estuary are critically endangered so being able to track and monitor trends is vital to the conservation of these populations.
