Abstract
Context The health of coral reefs is declining rapidly across the world because of anthropogenic impacts. In the mega-diverse Coral Triangle, the consequences of chronic overfishing and human use are worst near coastal population centres. Aims The remote islands and reefs in the centre of the Banda Sea (Indonesia) remain largely unstudied, but their distance from populated areas could provide protection from fishing. Methods We conducted the first visual census surveys of coral-reef communities at the uninhabited Lucipara group in the Banda Sea. Key results Sites showed medium to high coral cover and fish assemblages with high biomass, including abundant large predatory species. All sites exceeded the fish biomass conservation target of 1150 kg ha−1 proposed by McClanahan et al. (2015), by a factor of ~2–10. Benthic cover explained >50% of variance in fish abundance and diversity, with submassive corals, Dendrophyllia spp., and bare rock as key predictors. Conclusions Our results suggested that Lucipara’s reefs are among the healthiest in Indonesia, likely owing to their remoteness. However, this remoteness might also hamper policing against destructive fishing practices, highlighting a conservation gap. Implications Lucipara’s reef communities should be protected in a time of global coral-reef declines.
