Habitat comments: "a soft undulate and well drained plain... Natural vegetation was dominated by Prosopis alba and P. nigra accompanied by Aspidosperma quebracho blanco. However, as a result of agriculture and cattle farming, vegetation has undergone marked alterations. At present, the transitional landscape of woodland and pampean native grassland (Stipa spp.) persists in small remnants (patches) among crop-fields"
