ITPA was born in 1998, from the initiative of environmentalists committed to guaranteeing the protection of one of the last and most conserved fragments of Atlantic Forest, in Rio de Janeiro, the Tingu‡ Biological Reserve. We are currently the largest environmental organization based in the state of Rio, where we maintain dozens of work fronts, with more than 70 employees, and we have already planted 3.5 million trees. We are involved in forest restoration actions, creation and implementation of natural reserves, natural tourism, among others. The ITPA focuses on the bioregion called the Tingu‡ Bocaina Biodiversity Corridor. This is the most critical fragmentation region of the largest Atlantic Forest continuum in the country and comprises the main springs that supply water to the metropolitan region of Rio de Janeiro (about 10 million inhabitants). ITPA maintains many areas in the process of forest restoration, with more than 3.5 million native trees in partnership with almost 100 rural landowners, through voluntary area assignment contracts and payment contracts for environmental services. It also maintains the largest brigade for preventing and fighting forest fires, with very satisfactory results for natural regeneration. At the same time, we develop environmental education projects with schools in order to raise awareness and directly involve young people in the regeneration process of the Atlantic Forest. It should be noted that ITPA has a headquarters with all the infrastructure for educational and forest restoration actions, integrated with a Private Reserve of Natural Heritage and with buildings built in an ecological way.
