Laguna de Hueyapan (El Texcal). 02/02/10; Morelos; 276 ha; 18°54'N 99°09'W. This Ramsar Site includes a permanent freshwater spring and its surrounding area is located within "The Texcal" Ecological Conservation Area. The site is recognised for its hydrological importance for the region, including the main recharge area for the aquifers in the State of Morelos. It provides a reservoir of water for wildlife and is the habitat of endemic amphibians and birds like the Dusky Hummingbird (Cynanthus sordidus), and fish like the Balsas Shiner (Notropis boucardi). The Laguna de Hueyapan also sustains threatened species such as the Mexican leaf frog (Pachymedusa dacnicolor) and the Ridged Treefrog (Hyla plicata) listed as rare under Mexican regulation. The site is partially surrounded by the urban and industrial areas of Cuernavaca city. These areas put pressure on the site with main threats being the expansion of illegal settlements, water extraction for consumption, extraction of flora and fauna and the introduction of invasive species such as Rainbow Trout (Oncorhynchus mykiss). A Management Programme was published in 2005. Ramsar Site no. 1933. Most recent RIS information: 2010.
