The State Park of Pireneus was founded to protect the flora, fauna, watershed and historical sites of the Almas River forming region. Created in 1987 with an area of 2,833 hectares, the park was further protected when an additional surrounding 22,500 hectares of land was placed into APA (Environment Protection Area) status for preservation. This area includes the peak of Pireneus, Cabeludo Hill and many springs that feed the Almas and Corumba rivers.

These lands are characterized by rock formations, high meadows and well- preserved cerrado Eco systems as well as riparian systems, gallery forests and groves of buritis palms. In these lands one finds rich groves of ornamental trees such as jacaranda, canela de ema, caraiba or ipe do cerrado, and pau-papel the state tree of Goias. One also sees abundant medicinal plants like sucupira-branca, lobeira, and arnica (considered endemic and endangered due to over gathering), and native fruit trees including pequi, buriti, baru, xixa, mangaba and wild cashew.

Over 160 species of birds are to be found in these areas including the ema, siriema, arara caninde, papagaio-galego, azulao do cerrado, mineirinho and principe. Mammals in the region include monkeys, guariba, deer, and the tamandua-bandeira (endangered). The panthers, even the small ones, are gone with civilization.
