The watershed of the Huamanga-Vischongo Basins is located in the sub-humid eastern Andes of the Department of Ayacucho, between the valleys of the Yucay and Vinchos rivers. The Right of Way (RoW) rises and follows the boundary of the basins between the valleys of Huamanga (Mantaro Basin) to the north and the Vischongo River Basin (Apurímac Basin) to the south, passing almost entirely by puna pastures (91%), with occasional narrow stretches of puna grassland in formation (3%), bofedales (6%), and cultivated areas (<1%). The elevations vary from 3,864 to 4,250 meters above sea level (meters above sea level).


Floristically, this ELU contains populations of shrubs of Parastrephia quadrangularis and Escallonia myrtilloides, designated by Peruvian legislation as "vulnerable". The rarely observed Andean Cat, Leopardus jacobita, (cataloged by both the International Union for the Conservation of Nature-IUCN and by Peruvian legislation as "endangered") was seen in this ELU by the team that conducted the previous field assessments. . The area has a certain importance for the production of Vicuña (Vicugna vicugna), a wild relative of the Llama, whose wool is highly valued. Frogs of the genus Telmatobius were found in some of the streams of this ELU, indicating the existence of high quality habitats. Lizards of the genus Liolaemus are common in this ELU, with L. walker as a common species in the grasslands and L. cf. williamsi common among the rocks.
