Site description: This site is a federally-owned wetland (National Commission of Protected Natural Areas—CONANP) located within the El Vizcaino Biosphere Reserve. Bird monitoring is underway at the site (2016).

Known threats: Exploitation of renewable resources (salt mining, fishing, ecotourism) represents a threat to the site. Exportadora de Sal S.A. de C.V. is a salt-extraction company with a concession in the area. There is also fishing in the Ojo de Liebre Lagoon and ecotourism (particularly gray-whale watching). In terms of land use change, the threat of natural system modification is high, and specifically other ecosystem modification caused by blocking of natural water flows and altered salinity. Another threat is pollution in the form of solid and organic wastes derived from fishing activities and the accidental discharge of brines from "Exportadora de Sal S.A." facilities. The threat of physical alteration of the site due to climate change in the form of severe weather (i.e. storms and floods) is low.⁶,⁷

Notes: The site follows boundaries from WHSRN⁵.
