The Junín puna EBA covers two discrete areas of central Peru. Although the puna zone of the Peruvian Andes extends throughout the central and southern parts of the country, the restricted-range species which define the extent of this EBA are apparently confined to the areas around Lago de Junín (in the Junín department) and central Huancavelica department (there are records of just one species outside this immediate area in adjacent Lima and Pasco departments). The altitudinal limits of the puna are c.3,500-5,000 m, Lago de Junín being at 4,080 m. The climatically seasonal vegetation comprises tussocky grassland, some scrub and open rocky areas, with bogs and mires interspersed (often below glaciers); there are also some areas of woodland (Fjeldså and Krabbe 1990).Restricted-range species
Of the five birds confined to the EBA, Podiceps taczanowskii, Laterallus tuerosi and Geositta saxicolina are restricted to the area around Lago de Junín, the first two species being confined to the open water, submerged vegetation and surrounding marshland of the lake itself, while G. saxicolina is found in typical puna vegetation. The remaining two endemics also occur in the Junín area: Cinclodes palliatus is found additionally to the south in central Huancavelica, inhabiting the mineral-rich Distichia bogs of the upper puna zone; Oreotrochilus melano
Very few puna zone species have restricted ranges: however, although the puna seems quite uniform on casual observation, it is sufficiently complex to result in the patchy distributions of many birds (Fjeldså and Krabbe 1990). The local and patchy distributions of the birds in this EBA appear to reflect requirements that are only satisfied locally. The area around Lago de Junín was ice-free during the last glacial periods (the surrounding areas above c.4,000 m were generally covered in ice: Fjeldså 1992), and was presumably a refuge for the restricted-range species, three of which have not subsequently dispersed out of this immediate area (J. Fjeldså in litt. 1993).

Pollution and man-made changes in the water-level at Lago de Junín are factors that appear to be having adverse effects on the two lake endemics, and consequently both species are considered threatened. Cinclodes palliatus appears to have very specific habitat needs (though their precise nature remains unknown), and although not threatened from habitat destruction, the bird has a small and declining population which would be vulnerable should mining commence within its range (Collar et al. 1992, 1994). Pale-tailed Canastero Asthenes huancavelicae (classified as Vulnerable) is a more widespread threatened species found in this general area.
