The Callicebus Program is the first research programme of Proyecto Mono Tocón and currently includes three projects that focus on the collection of information for the creation of conservation measures for the San Martin titi monkey (Callicebus oenanthe).
The programme was initiated in 2007 with the Distribution Project, which has as principal objective the determination of the distribution range and taxonomic status of the San Martin titi monkey. The studies revealed that the species is restricted to an area of approximately 12.000 km². There is considerable phenotypical variation and in some areas it lives in sympatry with another species of titi monkey. The project resulted in sufficient information to determine, according to the IUCN criteria, the conservation status of the species and to initiate conservation actions.
The first studies will be followed by two new projects, the Density Project and the Corridors Project.
The Density Project is necessary to obtain specific information on C. oenanthe populations, to create effective conservation strategies. With the results of the project we will be able to calculate the carrying capacity of protected areas and the factors influencing the densities. Before starting to census a cryptic primate species like the titi monkey, it is important to investigate and evaluate different study methods. As part of the Density Project, Proyecto Mono Tocón has executed together with the NGOs AMPA and Neotropical Primate Conservation a study on the density of C. oenanthe in the Private Conservation Area Pucunucho, using a technique known as “triangulation of calls”.
The Corridor Project intends to realise a first habitat fragmentation diagnosis, which should result in the creation of a network of connected and protected forest fragments for the San Martin titi monkey. This project is part of a larger Peruvian project to preserve the remaining forest in the region and to create ecological corridors for plant and animal species.
The three research projects are open to the participation of institutions and persons that are interested in supporting research that promotes the conservation of Peru’s biodiversity.
