  1. Relocate nests/eggs for artificial incubation: Sea turtles

    A replicated, controlled study in 2007–2010 on 12 sandy beaches in Saona Island, Dominican Republic (Revuelta et al. 2013) found that artificially incubating hawksbill turtle Eretmochelys imbricata nests in boxes had similar hatching and emergence success compared to nests left in situ. Artificially incubated hawksbill turtle nests had similar hatching success (72–81%) and emergence success (69–80%) compared to nests left in situ (hatching success: 72–78%; emergence success: 67–72%). In 2007–2010, hawksbill turtle nesting activity was monitored on 12 beaches (0.01–2.10 km long) and nests deemed vulnerable to predation or harvesting were removed for artificial incubation in plastic boxes filled with sand and polyurethane foam (see original paper for details). Artificial incubation boxes were placed in a facility near one of the beaches (4 m long x 3 m wide) with a sand floor and wire mesh and corrugated metal walls. Hatching and emergence success was determined for clutches that were artificially incubated (20–41 nests/year, 119 total nests) and left in situ (7–21 nests/year, 49 total nests).
