Presa Jalpan. 02/02/04; Querétaro; 68 ha; 21°12'N 099°28W. The Jalpan dam was built on the riverbed of the Jalpan river, its only water source; it has a maximum capacity of 8 million liters and is a breeding site and shelter for 33 resident and migratory bird species. The greatest colonies are the Neotropic Cormorant (Phalacrocorax brasilianus) and some herons like the Snowy egret (Egretta thula), the Cattle egret (Bubulca ibis), and the Great egret (Casmerodius albus). There are in total 140 bird species around the dam, including waterfowl. Of the "non water" species, 8 have a special protection status and 5 are endemic in Mexico. Around the dam several mammal species can be found like the White-nosed Coati (Nasua narica), the Tree Ocelot (Leopardus weidii), the Jaguarondi (Herpailurus yagouaroundi) and occasionally the Cougar or Florida Panther (Felis concolor). The Jalpan dam is used primarily for water supply for domestic uses. Sedimentation caused by deforestation and erosion is the main threat to the area, though massive tourism is also a potentially key factor. Ramsar site no. 1352. Most recent RIS information: 2004.
