The ATRC has assisted with the long term monitoring of temperate reef ecosystems in the Jurien Bay and Ngari Capes Marine Park across the last two decades. It was instrumental in the establishment of the state’s first coordinated LTM program in the soon to be created Jurien Bay Marine Park in 1999. Currently in its 19th year, this dataset has now become a powerful tool for assessing MPA effectiveness and understanding the effects of a warming climate on the coastal ecosystems of temperate WA. Now with a broader group of associates, the ATRC provides DBCA with a national network of marine managers and researchers to facilitate knowledge exchange and future collaborative programs.
