1 Introduction

This section describes for each geographic region (Figure 32) the global Ecological Zones in terms of climate, physiography and vegetation. Vegetation descriptions focus on natural or potential vegetation, with information on physiognomy and (tree) flora. Few details are provided on current land use. Maps and tables show the distribution of the Ecological Zones by region and the area statistics are summarized in Appendix III-1.
