Humedal Los Comondú.02/02/08; Baja California Sur; 460,959 ha; 26°05'N 111°48'W. Situated in Sierra La Giganta, the wetland is distinguished by three large oases. It supports threatened species such as Geothlypis beldingi, Vireo bellii, Poliopotila californica, and endemic species like the Xantus's Hummingbird (Hylocharis xantusi). The site is of great importance for 36 species of Neotropical migratory birds, providing them with shelter and food. The main land uses are grazing and agricultural practices, as well as water extraction for agricultural, livestock and urban purposes. The greatest threats to the integrity of the site include hurricanes (which provoke flooding), the introduction of exotic flora species like the Common reed (Phragmites australis), Phoenix datylifera, the Buffelgrass (Pennisetum ciliare), and the Palay rubbervine (Cryptostegia grandiflora) causing the displacement of native species, and introduced fish species like the Guppy (Poecilia reticulata) and the Redbelly tilapia (Tilapia zilli). Ramsar site no. 1761. Most recent RIS information: 2008.
