Characterization of Polylepis tarapacana life forms in the highest-elevation Altiplano in South America: influence of the topography, climate and human uses

In the upper vegetation limit of the Andes, trees change to shrub forms or other life forms, such as low scrubs. The diversity of life forms decreases with elevation; tree life forms generally decrease, and communities of shrubs and herbs increase in the Andean highlands. Most of treeline population...
