This report describes the results of 17 years of monitoring shallow reefs (0-30m depth) in the Lord Howe Island Marine Park (LHIMP) based on data collected on 988 individual surveys over 10 monitoring campaigns, representing 45 monitoring sites across all zones of the LHIMP. These include data from reef fish surveys which include species, size and biomass information; finer-scale targeted surveys of large mobile invertebrates and cryptic fishes closely associated with the substrate; and analysis of percentage cover of coral, macroalgae and other sessile organisms from photoquadrats of the substrate. Surveys undertaken by RLS represent a highly cost-effective means to collect data on shallow reef biodiversity that is both rich in detail and facilitates ecosystem-scale analysis, while also maintaining a high standard of data quality consistent with a globally-standardised methodology.
