Augusto Weberbauer published, in 1922, the first vegetation map of Peru, where he showed and described twenty-five plant formations, grouped into six categories, considering altitudinal ranges defined according to their temperature. Within these categories are the microthermal formations that are generally found above 3400 masl and have a wide latitudinal distribution throughout the Peruvian Andes. To revalue that historical map, we present, firstly, the results of digitalization and estimation of extension of the four microthermal vegetation formations identified by Weberbauer, and secondly, the findings of cartographic contrasting between these microthermal formations, and the high Andean vegetation covers as classified in the most updated map on this subject. Weberbauer mapped an area of 183.445,30 km² for the four microthermal vegetation formations: typical high Andean formations (6...
