Vegetation and altitudinal zonation in continental West Greenland
Following the principles of the Braun-Blanquet approach a detailed investigation of the vegetation types of mountains in continental West Greenland is presented. The vegetation types are analysed regarding their subdivision into subassociations, variants and elevation forms, as well as the prevailin...
