In year 2000, a comprehensive animal adoption program was proposed by Taipei Zoo to strengthen the visitor s supports of wildlife conservation programs that have been conducted or will be soon activated. Three designing principles behind this program are wildlife born in equal; visitor s equal opportunity for participation; and conservation of biodiversity, especially the native wildlife. Knowledge gained from both in-situ and ex-situ studies will be applied to zoo designs, animal daily husbandry, educational activities and management works. We foresee a close relationship between the success of the animal adoption program and the continuous values of Taipei Zoo existence.
