Humedales de Montaña María Eugenia. 02/02/12; Chiapas; 86 ha, 16°43'N 092°37'W. Área Natural Protegida. A high altitude wetland (2,120m asl), important for its major role in the prevention and control of flooding. As an urban wetland, it is important for the recharge of aquifers to supply water to San Cristobal de las Casas. The site supports large populations of fish, birds, and amphibians, of which 5 have been identified as endemic or under a protection category, according to the IUCN Red list: the endemic fish Profundulus hildebrandi and Ergaticus versicolor, both in danger of extinction, and critically endangered Plectrohyla pycnochila, Abronia lythrochila, and Carduelis atriceps. The site is also an important resting place for migratory birds, and a refuge for local species. It is critical for the survival of populations of resident species, e.g, Micropterus salmoides, Lithobates brownorum, and Tamnophis proximus. Among negative factors are the constant increase of the population and the unorganized spread of housing, which have caused the area to diminish in size and led to deforestation. Since 2006, there is a recreational area designed for tourism and environmental education. A promising management programme has been approved. Ramsar Site no. 2045. Most recent RIS information: 2012
