The area was originally part of the Fazenda Santa Genebra, a coffee plantation owned by Baron Geraldo de Resende, which covered the present Barão Geraldo de Resende district and some parts of the city of Campinas. The Baron invested heavily in new technology for his plantation and went bankrupt. His lands were auctioned off, and the Oliveira family bought the part that holds the forest, which they preserved. José Pedro de Oliveira, who became owner, thought that the fresh air of the forest would help control his tuberculosis. After his death his widow donated the forest to the municipality. On the date of the donation, 14 July 1981, the Fundação José Pedro de Oliveira was established to use the forest for strictly scientific and cultural purposes. In 1983 Mata de Santa Genebra was designated a National Heritage area. Mata de Santa Genebra Area of Relevant Ecological Interest was created by decree 91.885 on 5 November 1985.
