CORAL OUTPLANTING WORKSHOP Coral Outplanting Workshop Central Caribbean Marine Institute Cayman Islands Department of Environment Project advisor Dr. Diego Lirman (University of Miami, Rosenstiel School of Marine and Atmospheric Science) June 27-28, 2013 Little Cayman Prepared by Katie Lohr Conservation Scientist, CCMI July 2013 June 1, 2013 CORAL OUTPLANTING WORKSHOP June 1, 2013 I. Workshop Overview The objectives of the Coral Outplanting Workshop organised by the Central Caribbean Marine Institute (CCMI) with the participation of the Cayman Islands Department of Environment (DOE) and the University of Miami were to (a) review the long-term goals of the collaborative Coral Nursery Project, (b) instruct workshop participants on best-practice coral outplanting techniques, and (c) provide participants with relevant field experience in coral outplanting. An ancillary purpose of this workshop was to create an opportunity for CCMI and DOE to discuss the following steps required to maintain the coral nursery in order to match the long-term goals of the project. This document will summarise the main outcomes of the workshop. II. Pilot Outplanting A total of 68 small fragments were transplanted from the nursery to two reef sites. Thirty three fragments were outplanted onto ICON Reef and 35 onto Coral City. ICON reef was selected as an ideal pilot outplanting location because of its convenient location, just a few metres north of the existing nursery. This shallow site (~30 ft), characterised by a spur-and-groove topography, will be easily accessed from CCMI for monitoring purposes. Coral City (~35 ft), located on the south side of the island, was selected as a second outplanting site given that it was home to two of the parent colonies that were fragmented to populate the nursery. The 68 outplants represent four of the five genotypes currently growing in the nursery. Sites within ICON reef and Coral City were selected based on the availability of hard non-living substrate and the absence of competitors (e.g. Agaricia spp., Millepora spp., gorgonians, and fleshy algae). To select the location for individual fragments on the substratum we delineated a 1 x 1 m grid within a 5 x 5 m of reef using transect tapes. To provide an attachment point for each colony 4-inch masonry nails were installed on the substratum directly under the intersections of the grid. Algae and sediment were removed from within approximately 1 inch around the nail. A small amount of marine epoxy was placed at the base of each nail to secure it and to provide an additional site of attachment for the coral fragments. Fragments were attached to the nails by pushing the base of the colony into the epoxy and securing the main branch of the fragment to the masonry nail with two cable ties. The bottom cable tie was colour-coded to indicate the genotype of each fragment. Fragments were measured 0-6 days after installation, and will be checked one month following outplanting, and quarterly thereafter.
