Laguna de Babícora.02/02/08; Chihuahua; 26,045 ha; 29°20'N 107°50'W. Located in the biogeographic region of the Sierra Madre Occidental, this complex is composed of a series of small lagoons that bond together as the source of the basin recharges, arising to the surface. It is of great importance for 122 species of migratory birds including the Greater White-fronted Goose (Anser albifrons) and the Whimbrel (Numenius phaeopus). Threatened species like the Mexican Duck (Anas platyrhyncos diazi) and the Mountain Plover (Charadrius montanus) find shelter in this lagoon, which also holds the greatest number of geese in the Mexican Highlands, 5 endemic flora species (new for Mexico) Desmonim sp., Helenium chihuahuense, Hydropectis estradii, Thynchosia macrocarpa and Tragon porrifolius and two new for science: Hydropectis estradii and Desmonium sp. Agriculture and livestock are the main productive activities in the site. Among the threats the most damaging are drying of lagoons for livestock and agriculture purposes, agrochemical pollution, and urban waste waters. Babícora is part of the program Areas of Importance for the Conservation of Birds. Ramsar site no. 1762. Most recent RIS information: 2008.
