The Andean or San Martín Titi monkey (Callicebus oenanthe) has one of the smallest geographic ranges of Peruvian primates. Unfortunately for this species, land conversion by humans has decimated the central part of its narrow ~16,000 km2 range in northern central Peru. Currently the Titi’s habitat extent consists of a series of forest fragments amid human agriculture and development and is restricted by higher elevation cloud forests that hosts a competing species. It is imperative that important patches linking forest remnants be identified and subsequently protected to preserve this critically endangered species amid the growing human matrix. We have mapped remaining habitat patches with recent satellite imagery (GeoEye, SPOT, Aster) in the northern extent of the Tocón’s range where human impact has been highest. Working with the field surveys and biologists of Proyecto Mono Tocón, a local NGO in the region, we identify which remaining patches comprise viable habitat for the species and analyze connectivity between these primary patches. We identify the most important patches for conservation based on network analyses and identify barrier areas that can be made targets for reforestation and protection efforts. The prioritization of these remnants for protection is essential to the survival of this species amid the increasing deforestation and limited conservation resources in this area.
