Create artificial nests or nesting sites
A study in 2009–2011 in tropical rainforest on Reunion Island, Indian Ocean (Sanchez 2012) found that some artificial egg-laying sites in a habitat restoration area were used by Reunion day geckos Phelsuma borbonica in the year they were installed and the number of sites used and eggs laid increased in the second year. Nine months after artificial egg-laying sites were installed, four of 34 sites were used by geckos and 10 eggs were laid. Two years after the first artificial egg-laying sites were installed, eight of 40 sites were used by geckos and 41 eggs were laid. In total, 40 artificial egg-laying sites were added to an area (9,000 m2) of degraded habitat in a hydroelectric power plant in September 2009–July 2010 (34 were installed by June 2010 and a further 6 by July 2010). Artificial egg-laying sites comprised hollow, rectangular metal poles (4 x 8 x 250 cm) inserted into the ground (50 cm deep). Native plant species were planted in the same area to restore habitat (22,000 plants of 50 species). Egg-laying sites were monitored for signs of geckos and egg laying in June and September 2010, and March and September 2011.

Restore former mining or energy production sites
A study in 2009–2011 in tropical rainforest on Reunion Island, Indian Ocean (Sanchez 2012) found that some artificial egg-laying sites in a restored area in a hydroelectric power plant were used by Reunion day geckos Phelsuma borbonica in the year they were installed and the number of sites used and eggs laid increased in the second year. The effects of restoration and the provision of egg laying sites cannot be separated. Nine months after artificial egg-laying sites were installed, four of 34 sites were used by geckos and 10 eggs had been laid. Two years after the first artificial egg-laying sites were installed, eight of 40 sites were used by geckos and 41 eggs had been laid. Native plants (22,000 plants of 50 species) were planted in an area (9,000 m2) of degraded habitat in a hydroelectric power plant to restore habitat. In September 2009–July 2010, forty artificial egg-laying sites were added to one area (34 were installed by June 2010 and a further six by July 2010). Artificial egg-laying sites comprised hollow, rectangular metal poles (4 x 8 x 250 cm) inserted into the ground (50 cm deep). Egg-laying sites were monitored for signs of geckos and egg laying in June and September 2010, and March and September 2011.
