Coral restoration is increasingly used worldwide to restore functionality of coral reef habitats and to re-establish self-sustaining coral populations where natural recruitment has been depleted. A key metric of restored coral populations is ensuring resilience to future stressors, which requires that genetic diversity is maximised. However, genetic diversity (and extent of clonality) can be highly variable across sites via the relative success of sexual and asexual recruitment. Determining the genotypic (clonality) and genetic diversity of source colonies for restoration is therefore critical to avoid causes of loss of fitness, such as founder effects and genetic swamping. Due to recent loses of Acropora on the Great Barrier Reef resulting from back-to-back bleaching events in 2016/17, the propagation of this genus has been favoured by reef stakeholders within the region. Here we examine the variations in clonality of a commonly out-planted species, Acropora hyacinthus, over reef sites and between reefs throughout 6 reef systems on the northern and central Great Barrier Reef. Novel SNP analyses conducted on 162 sampled colonies will be used to determine differences in clonality and diversity within sites and geographic regions. We discuss how this knowledge can be applied by stakeholders to enhance coral propagation practices.
