The black-faced lion tamarin (Leontopithecus caissara) was discovered in 1990 (Lorini & Persson) and is among the world's 25 most endangered primate species. It is estimated that only 400 individuals exist in the wild, distributed in a narrow coastal strip, which stretches from the south of the state of Sao Paulo to the extreme north of the state of Parana, consisting of approximately 300 km² in area.
Aiming to ensure their permanence in nature, in 1995, IPÊ initiated the "Black-faced Tamarin Conservation Program" with the objective of gathering the necessary information for the creation of a management plan that would reflect the true reality of the species in nature. Over the past 10 years, diverse research programs have been implemented to better define the management scenario, such as, aspects of feeding ecology, geographic distribution, temporal budget, daily movement and habitat use patterns, territory area, behavior, demographic density, population health and availability, and habitat quality.
In parallel with this research, since 1997 IPÊ has implemented an environmental education and community involvement program together with the communities of Superagüi and the surrounding regions. The program has the objectives of sharing the scientific information that is gathered through accessible language that can be understood by everyone. The program also aims to strengthen the abilities and aptitudes of the local people, through sustainable practices that focus on the region's nature. In this way both human beings and nature in general benefit, and conservation can thus be enhanced.
Currently, IPÊ is monitoring groups of black-faced lion tamarins in the continental portion of their area of distribution. The results of this study will be compared with those from the study previously conducted of groups on the island of Superagüi. This will help make future management decisions that take into account their needs in relation to their habitat. IPÊ is also assessing the main threats to the species and its habitat on the continent with the objective of identifying the management steps that can be taken in the future, as translocations for example. This assessment also aims to define the environmental education and community involvement program for the continental region, which has different social and cultural realities from those found in Superagüi.
