Informing coral outplanting efforts from Airborne maps

Asexual propagation is a popular and widespread technique for coral restoration. Coral outplanting is normally conducted from water-based nurseries located nearby restoration sites. In the Dominican Republic, the process of outplanting corals has been propelled by fostering the participation of local people in events known as "coral manias". In the past, sites were selected solely through local knowledge and observations. The Nature Conservancy and Arizona State University's Center for Global Discovery and Conservation Science have taken a step forward by developing a decision support tool to inform site selection based on environmental criteria derived from GAO maps. The tool, coupled with local knowledge, was successfully implemented during a coral mania organized by Fundación Grupo Punta Cana in Cabeza de Toro, Bavaro. This event brough together dozens of volunteers belonging to NGOs, Dominican environmental authorities, dive operators and other local stakeholders aimed to outplant 1,711 Acropora cervicornis fragments. This case study proved to be effective in selecting suitable sites for coral outplants and represents a promising area of research for scaling up restoration efforts.
Photogrammetry to monitor coral restoration in the USVI
Cane Bay, St. Croix, US Virgin Islands. Structure-from-Motion data collected at different timepoints allows powerful growth and erosion change detection using both the photomosaics and digital surface models. Left: pre-outplanting.
