Lake Güija is divided by the border between Guatemala and El Salvador. The IBA includes about 25% of the lake and surrounding terrestrial habitat.
Lake Güija has global importance for biome-restricted species of the Pacific Arid Slope, according to a rapid assessment (Tenez 2006). Although the site does not meet thresholds of global importance for waterbird populations, it supports thousands of migration waterbird species (Herrera & Ibarra 2005, Eisermann 2006, Sigüenza 2007).
