Location of study sites along the elevation gradient in Polylepis forest of Huascaran National Park, Peru

Five glacial valleys, Paron, Llanganuco, Ulta, Llaca and Rajucolta were surveyed for birds and habitat characteristics in 130 points from 3,300 to 4,700 msnl.

Vegetation communities located along an Andean elevational gradient

These include A) Eucalyptus forest usually at lower elevations, B-C) shrub areas dominated by Gynoxys/ Budleja/ Baccharis/ Lupinus species, D) Puna grassland areas dominated by Stipa ichu and E) Polylepis sericea woodland at lower and F) Polylepis weberbaueri at upper elevation.

Non-Metric Multidimensional Scaling NMMS ordinations of 130 points based on 19 habitat and physical characteristics along a 2-dimensional axis coordinates

For visualization purposes, dot points represent locations below 3,800 m, cross points between 3,800 to 4,200 m and square points over 4,200 m in elevation.
