Vegetation classification is the process of classifying and mapping the

management. Many different methods of vegetation classification have been used. In general, there has been a shift from structural classification used by forestry for the mapping of timber resources, to floristic community mapping for
biodiversity management. Whereas older forestry-based schemes considered factors such as height, species and density of the woody canopy, floristic community mapping shifts the emphasis onto ecological factors such as climate, soil type and floristic associations. Classification mapping is usually now done using

* A. The soil (in the widest sense) is very wet, and the abundant water is available to the plant (at least in Class 1), the formations are therefore more or less hydrophilous:
** Class 1. Hydrophytes (of formations in water).
** Class 2. Helophytes (of formations in marsh).
* B. The soil is physiologically dry, i. e. contains water which is available to the plant only to a slight extent; the formations are therefore essentially composed of xerophilous species:
** Class 3. Oxylophytes (of formations on sour (acid) soil).
** Class 4. Psychrophytes (of formations on cold soil).
** Class 5. Halophytes (of formations on saline soil).
* C. The soil is physically dry, and its slight power of retaining water determines the vegetation, the climate being of secondary import; the formations are therefore likewise xerophilous:
** Class 6. Lithophytes (of formations on rocks).
** Class 7.

** Class 8. Chersophytes (of formations on waste land).
* D. The climate is very dry and decides the character of the vegetation; the properties of the soil are dominated by climate; the formations are also xerophilous:
