Plomito Ranch counts with a great diversity of flora and fauna, not to mention hunting species such as the desert bighorn shee, which rank first in our much appraised national wildlife, huge mule deer and sharp coues deer, as well as collared peccary. The Sonoran desert is part of the vast American corridor of dry ecosystems that stretches from the southeast tip of the State of Washington, in the US, south to the State of Hidalgo, within the central Mexican plateau; and from central Texas east to the Pacific coast in the Baja California peninsula, covering almost a million square kilometers.
