Unit "UMA-El Pandeño SDUE-UMA-EX-096-CHIH-12". In November 30, 2013, an area of 368 ha (909 Acres) comprising a group of springs and irrigation canals, including "El Pandeño" hotspring was nominated Ramsar Site No. 2201: "Manantiales Geotermales de Julimes"(Geothermal Julimes Springs) by the Ramsar Convention on Wetlands on the basis of the unique ecosystems present, and the endemic organisms, including the Julimes pupfish, the isopod Thermosphaeroma macrura and the gastropod Tryonia julimensis, which have adapted to the extreme conditions which these systems present. The site is also a Grassland Priority Conservation Area, as it acts as a resting and feeding area for migratory birds traveling over the desert areas of Chihuahua State, which have very few water bodies especially during the dry winter season.
