Overview
Joannesia princeps, the arara nut-tree or andá-açu, is a species of moderate-sized tree in the family Euphorbiaceae, with a spreading canopy, large alternate and long petioled leaves, and coarse branches. Flowers are monoecious, and fruit is a large drupe. It is endemic to east Minas Gerais, north Espírito Santo to the south of Bahia, Brazil, and threatened by habitat loss.
The arara nut-tree faces significant pressure from habitat loss due to deforestation and agricultural expansion throughout its Atlantic Forest range. Additional threats include selective logging for its valuable timber and limited natural regeneration due to seed collection and fragmented populations.
Habitat
Endemic to Brazil's Atlantic Forest (Mata Atlântica), occurring in humid tropical forests, forest edges, and secondary growth areas primarily in the states of Rio de Janeiro, Minas Gerais, and Espírito Santo. The species typically grows in well-drained soils of montane and submontane forest zones.
