Northern Andes Ecoregional Complex
Located in the highlands of tropical Andes, this complex extends from 11° North latitude in northern Colombia, 2,000 km southward to northern Perú, at approximately 6° South latitude. The recognized northeastern limits of the NAEC are Sierra de Perijá (Colombia, Venezuela) and Merida Cordillera (Venezuela).
The northwestern limit is Sierra Nevada de Santa Marta (Colombia). The southern limit is Abra de Porculla mountain pass in Huancabamba depression (Peru) that serves as a biogeographic barrier to species movement, separating the northern and southern Andes.
