El Jagüey, Buenavista de Peñuelas. 02/02/2011; Aguascalientes; 35 ha; 21°43' N 102°19'W. The site features six seasonal freshwater and two artificial ponds that are home to eight species of amphibians (four of them endemic to Mexico) and five species of invertebrates endemic to this wetland, as well as to the only viable breeding population currently known worldwide of the endangered species Smilisca dentata (Upland Burrowing Treefrog), whose habitat type, the natural grassland-huizachal, is restricted. Natural floods during the summer are key to the balance of the biological community gathering as part of their life cycles, such as feeding, breeding, resting and shelter. Adverse factors affecting the site include motor traffic on the boulevard to the Jesus Teran Airport causing the trampling of individuals of the Smilisca dentata, the construction of houses, warehouses and silos for livestock feed, and an increase in the number of paddocks. The planned creation of a Natural Protected Area in the Category of Sanctuary of the Upland Burrowing Treefrog will consist of 201 ha, including all eight ponds of the Ramsar Site. There is presently no management plan in place, but it will be prepared after the Ramsar designation. Ramsar Site no. 1972. Most recent RIS information: 2011.
