This species presence in riparian areas of the Caatinga of northeastern Brazil is a crucial resource for Spix's macaw (Cyanopsitta spixii), which is extinct in the wild with fewer than 100 birds remaining in captivity. Any future reintroduction would have to provide sufficient T. aurea for nesting and other purposes - while the tree is not considered threatened on a global scale, locally it has declined due to unsustainable use for timber.
