Chapter 3 provides a detailed classification of vegetation types, emphasizing the importance of altitudinal zonation and dividing the vegetation into forest, shrubland, herbaceous, and pioneer formations. One of the accompanying maps is a 1:2,000,000-scale color vegetation map; the other is a topographical and toponymical map at the same scale.
