Laguna La Juanota. 30/10/13; Chihuahua; 232 ha; 26°29’13”N 106°28’28”W. The Site, an endorheic lagoon, is located in the Sierra Madre Occidental range at 2,697 metres above sea level, making it the water body with the highest altitude in the State of Chihuahua. Its importance is due to its role in controlling and preventing floods and in retaining seasonal water. It supports numerous species, including migratory birds. Threatened or endangered species and subspecies include the parrot Rhynchopsitta pachyrhyncha, the endemic squirrel Sciurus aberti durangi, the endemic hare Lepus californicus sheldoni and the duck Anas platyrhynchos diazi. The lagoon has historically been considered the most important habitat for this last subspecies. Besides its importance for fauna and flora, it is vital for the economy of the neighbouring communities, which include Rarámuri indigenous groups. The lagoon captures the water they need for their agricultural livelihoods. As the only input of water is from rain, the main threat is extended drought. Overgrazing and deforestation in the surrounding area also pose threats as they result in soil erosion and increased water salinity. Ramsar Site No. 2206. Most recent RIS information: 2014.
