Chek Lap Kok
Over 200 individuals of the species were rescued from Chek Lap Kok in 1992, before the construction of the new Hong Kong International Airport. The captives were bred successfully and the offspring were released into eight selected sites in Hong Kong Island and New Territories. The frogs in seven of the sites survived. Surprisingly, a very small number of them also survived in Chek Lap Kok.
