 The high rates of endemism throughout the tropical Andes (Amboró is no exception) suggest quite strongly that at least some of the undocumented plant species yet to be discovered within Amboró will almost certainly be Amboró endemics that are currently unknown to science.Of the documented species, some of the most ecologically and economically interesting are bigleaf mahogany, mountain pine, black walnut (no relation to the eastern North American tree of the same name), limachu, q'illu q'illu ("Berberis bumaelifolia", also spelled "khellu khellu"), cebillo, bibosi, ambaiba, pacay, and clavo rojo.In the cloud-enveloped forests there are extensive patches of giant tree ferns.
