Abstract

Reporting progress against targets for international biodiversity agreements is hindered by a shortage of suitable biodiversity data. We describe acost-effective system involving Reef Life Survey citizen scientists in the systematic collection of quantitative data covering multiple phyla that canunderpin numerous marine biodiversity indicators at high spatial and temporal resolution. We then summarize the findings of a continental- anddecadal-scale State of the Environment assessment for rocky and coral reefs based on indicators of ecosystem state relating to fishing,ocean warming, and invasive species and describing the distribution of threatened species. Fishing impacts are widespread, whereas substantialwarming-related change affected some regions between 2005 and 2015. Invasive species are concentrated near harbors in southeastern Australia,and the threatened-species index is highest for the Great Australian Bight and Tasman Sea. Our approach can be applied globally to improvereporting against biodiversity targets and enhance public and policymakers’ understanding of marine biodiversity trends.
