Humedales de Montaña La Kisst. 02/02/08; Chiapas; 36 ha, 16°44'N 092°39'W. Área Natural Protegida. A high altitude wetland (2,120m asl), important for humans as it captures, filters, stores and provides clean water; the springs found in the area are the primary supply of clean water to San Cristobal de las Casas. The site supports great populations of fish and amphibians, of which 10 have been identified as endemic or under a protection category, e.g., the endemic fish Profundulus hildebrandi and Ergaticus versicolor, both in danger of extinction. The Bearded Screech-Owl (Otus barbarus) is a threatened species, and subject to special protection are: the frog species Plectrohyla pycnochila and Eleutherodactylus glaucus. The site is also an important resting place for migratory birds. 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, and constant freshwater pumping has caused the depletion of water and the drying out of many parts of the wetland. Ramsar site no. 1787. Most recent RIS information: 2008.
