The Philippine Tarsier Foundation, Incorporated (PTFI) is a non-profit, non-stock corporation based in Tagbilaran City, Bohol, Philippines, established in 1996 to conserve, promote research and establish a sanctuary for the Philippine Tarsier. It is an entirely private sector initiative, but has strong support from two leading organizations in conservation and eco-tourism, namely the Department of Environment and Natural Resources (DENR) and the Department of Tourism (DOT). To ensure the continued existence of the Philippine Tarsier, the Foundation is attempting to bring tourism to the province of Bohol in a way that is ecologically friendly to the Philippine Tarsier.
