Habitat comments: "The local original vegetation was formed by a transitional zone between semi-deciduous Atlantic forest and Cerrado" but was deforested in the 19th century, and then in the 1970s there was a "massive deforestation of the second growth vegetation... in order to implant exotic pastures for livestock production... in the remaining fragments of native vegetation, selective logging occurred until 2006" and at that time some was "converted into Eucalyptus production forests"
"subtropical (Cwa in Köppen climate classification)"
