We present a method for making best guess estimates for the conservation status of 20 Indonesian tarsier taxa and populations listed in the taxonomy of Brandon-Jones et al. (2004). Published distribution maps were used to make rough estimates of the extent of occurrence. The accuracy of our estimates is sufficient that nearly all taxa and populations can be confidently assigned to one of the four size-based categories (i.e. 1 - 100 km², 100 - 5000 km², 5000 - 20,000 km², >20,000 km²) in the IUCN Red List guidelines. We used data and reports concerning habitat loss throughout Indonesia, and inferred commensurate range fragmentation, and declines in habitat quality and overall population numbers throughout the range of tarsiers in Indonesia. These inferences were supplemented with other information and personal observations where available. Based on our calculations, we make the following recommendations for the conservation status of Indonesia's tarsiers. One taxon and one population warrant Critically Endangered (CR) status: Tarsius bancanus natunensis and T. sangirensis Siau population. Three taxa and four populations warrant Endangered (EN) status: Tarsius pelengensis, T. pumilus, T. sangirensis, and four acoustic forms of T. tarsier (i.e., the Tinombo form, the Togian form, the Selayar form and the Kabaena form). Indonesian tarsier species that we recommend be listed as Vulnerable (VU) include two taxa and three populations: Tarsius bancanus saltator, Tarsius dentatus (=dianae), and three acoustic forms of T. tarsier (=spectrum) (i.e., the Manado form, the Gorontalo form, and the Buton form). Indonesian tarsier species that we recommend be listed as Lower Risk include two taxa: Tarsius bancanus bancanus, and Tarsius bancanus borneaus. Indonesian tarsier species which we regard as data deficient include one taxon and three populations: Tarsius tarsier (i.e. T. tarsier, the Makassar form), and three other acoustic forms of T. tarsier (the Sejoli form, the Palu form, and the Kendari form). The Palu form has since been described as T. lariang. Several of these taxa / populations are distributed in regions that completely lack conservation areas of any kind. These include the two Critically Endangered forms (T. b. natunensis, T. sangirensis Siau population), four of the Endangered forms (Tarsius pelengensis, Tarsius sangirensis, Togian form, and Selayar form), and one Vulnerable form (Tarsius bancanus saltator).
