This long EBA embraces the Pacific slope and coastal lowlands from northernmost Lima department (c.11°S), south through Ica, Arequipa, Moque
This EBA is desert, almost totally devoid of vegetation save strips of dense Salix and Schinus scrub along the few river valleys that bring water from the distant Andes. At slightly higher elevations (c.1,000 m), precipitation from winter coastal fogs (which form over the cool Pacific Ocean currents) support the 'lomas' formations of annuals, shrubs, cacti and Tillandsia-clad trees; elsewhere, the rocky mountain slopes are covered in arid cactus scrub, with higher areas supporting Polylepis woodland and scrub (Fjeldså and Krabbe 1990, Dinerstein et al. 1995).Restricted-range species
The restricted-range species variously occupy all habitats, with populations or subspecies in the north tending to occur at lower altitudes than the equivalent populations further south (Fjeldså and Krabbe 1990).
Three species-Cinclodes taczanowskii, Geositta peruviana and Sporophila simplex-are shared with the adjacent Tumbesian region (EBA 045) to the north; they are primarily coastal birds with the greater part of their ranges in the northern coastal area, although both the genera Cinclodes and Geositta originated as radiations from southern Patagonia (J. Fjeldså in litt. 1993).

Overgrazing by domestic livestock, alteration of water flow patterns in the river valleys, and firewood collection all threaten the vegetation in this area (Dinerstein et al. 1995). Almost all available flat areas in the vegetated river valleys have been cultivated, as have many of the inter-montane valleys; however, the arid vegetation of the remaining areas is still essentially intact (Fjeldså and Krabbe 1990, Collar et al. 1992).
Three restricted-range species in this EBA are considered threatened, two of which (Eulidia yarrellii and Conirostrum tamarugense) are confined to the southernmost portion: E. yarrellii is confined to just a few arid valleys where extensive cultivation has led to its almost total reliance on flowering plants in gardens; C. tamarugense is almost certainly an altitudinal migrant, and for at least part of the year relies wholly on the now much-depleted high-elevation Polylepis
Six Key Areas in Peru and six in Chile have been identified for the conservation of these threatened birds (Wege and Long 1995). These include, at the southernmost end of the EBA, two Key Areas for Conirostrum tamarugense, both of which are protected within the Pampa del Tamarugal National Reserve. In Peru, protected areas (important for threatened species) include the Salinas y Aguada Blanca National Reserve (from which there are records of the widespread but threatened White-tailed Shrike-tyrant Agriornis andicola, classified as Vulnerable) and the Laguna de Mejía National Sanctuary. The Paracas National Reserve embraces a number of arid islands, of which Isla San Gallán supports one of the largest remaining populations of the Peruvian Diving-petrel Pelecanoides garnotii (Endangered), and is potentially of importance for a couple of restricted-range species.
