regional lists by both the Paraná and São Paulo states. The Superagüi National Park covers most of the black-faced lion tamarin home ranges including Superagui Island and adjacent mainland parts of the state of Paraná. The national park is 33,988 hectares large and the black-faced lion tamarin is one of the endemic species that is used as a conservation unit for management of the park. The population in São Paulo is protected in the Jacupiranga State Park. The Instituto de Pesquisas Ecológicas (IPÊ) began the black-faced lion tamarin conservation program in 1996 and through 2004 focused on learning the ecology and natural history of the species. In 2005, enough data was collected to create the first conservation action plan for the black-faced lion tamarin and its habitat. As well as collecting additional data, from 2005 to 2007 IPÊ completed a diagnostic of threats to the survival of the species. They then hosted the first Eco-Negotiation Workshop in Ariri (São Paulo) in 2009, with a focus on education and awareness of sustainable production. Currently some of their objectives include evaluating dispersal of young, refine the projected population, observe the effects of sea rise due to climate change, and promote sustainable harvest of heart-of-palm.
