The Philippine Tarsier Foundation Inc. based in Tagbilaran City, Bohol, Philippines is spearheading the campaign to preserve the Philippine Tarsier. Under a Memorandum of Agreement with the DENR signed on April 27, 1997, its mission is: to establish a forest reserve on the island of Bohol which shall serve as the sanctuary of the Philippine Tarsier; to protect and manage the tarsier sanctuary through the active participation of local communities; to establish and maintain a wildlife research laboratory for the study of the ecology and biology of the Philippine Tarsier; to establish and maintain visitor facilities for ecotourism and disseminate information material about the Philippine Tarsier with emphasis on the species' protection and conservation."
To date, the Philippine Tarsier Foundation has acquired 7.4 hectares of land in Corella, Bohol for the sanctuary. With the Department of Environment and Natural Resources playing an oversight role, the foundation has asked other Bohol towns with Philippines Tarsier populations to donate 20 hectares (49.4 acres) of forestland for conservation.
It also runs a Tarsier Research and Development Center, which serves as a visitor center and venue for research, as well as a habitat preserve. At the sanctuary, a spacious net enclosure keeps 100 Philippine Tarsiers for feeding, captive breeding and display. Here, visitors can observe the Philippine Tarsier in their natural habitat. Within the sanctuary, the Philippine Tarsiers roam freely and all of them have gotten used to a seven-foot high fence that circumscribes the territory and which serves mainly to protect them from predators like feral cats. At night, tarsiers can be seen climbing out of the fence to forage for food farther into the forest. They return again before daybreak, as if observing a curfew.
