[1][4] The Union Island gecko is threatened by demand from the international pet trade.

Due to its distinct markings, it is one of the most trafficked reptiles in the Eastern Caribbean.

[5] The specific name, daudini, is in honor of naturalist Jacques Daudin (1926–2011) who lived on Union Island.
