Extremely high but localized pulses of coral recruitment in the southwestern lagoon of New Caledonia and implications for conservation

A study of coral recruitment in the southwestern lagoon of New Caledonia revealed exceptionally high and localized pulses, with rates reaching up to 13572.8 recruits per square meter—far surpassing global averages. These extreme peaks, observed between 2012 and 2014, were dominated by Acroporidae and contrasted sharply with declining trends reported elsewhere, suggesting resilience in this UNESCO World Heritage Site. Researchers analyzed 14 reef stations, uncovering marked spatial and interannual variability that complicates conservation efforts. While the findings highlight potential for population replenishment, the unpredictability of recruitment hotspots challenges targeted protection strategies.
