Transplant nursery-grown coral onto natural substrate
A replicated study in 2016–2017 at two coral reef sites in Florida, USA (O'Donnell et al. 2018) found that most nursery-grown staghorn coral Acropora cervicornis colonies transplanted onto the natural reef survived and increased in size. One year after transplanting, the average survival rate of fragments did not differ between the two sites (86 and 92%). Although the average size of colonies at transplanting did not differ between sites (site 1: 171 mm; site 2: 189 mm), size was higher at site 1 (751 mm) than site 2 (598 mm) one year later. In May 2016, one hundred nursery-grown staghorn colonies (100–200 mm with at least two branches) were transplanted 45 m deep on two coral reefs. At each site, colonies were arranged in two arrays (~3–5 m apart) each with five clusters (~0.5–1 m apart) of five colonies (~10–15 cm apart). Colonies were attached to the substrate using masonry nails and cable ties. Survival was recorded after one year. Growth (measured as total linear extension including all branches) was recorded approximately 3, 6, and 12 months after transplanting.
