Habitat and Ecology
This species chiefly occurs on a larval cliff with many crevices close to the sea coast and flanked with shrubs and secondary forests in the southeastern part of the island. It can also be found beneath the bark or within crevices in trees of secondary forests in the same region (Ota 1987), but the population density around this type of habitat is much lower (H. Ota pers. comm.).

Justification
Gekko kikuchii has been assessed as Data Deficient. This species has an extremely small distribution. However, where distributed, its population density is high. The threats to this species are not well known and so further research is needed before a more accurate assessment of the conservation status of G. kikuchii can be made.

Major Threats
There are threats to Lanyu Island such as habitat loss and degradation due to agriculture and a developing tourist industry. However, it is unknown what impact this may have on the species at this time, because the larval cliffs it inhabits are not directly affected.
