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 geographic information systems (GIS) software.

Wagner & von Sydow (1888)

Wagner Wilhelm Richard Wagner ( ; ; 22 May 181313 February 1883) was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas (or, as some of his mature works were later known, "music dramas"). Unlike most op ...

* 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.

s (of formations on sand and gravel). ** 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: ** Class 9. Eremophytes (of formations on desert and steppe). ** Class 10. Psilophytes (of formations on savannah). ** Class 11. Sclerophyllous formations (bush and forest). * E. The soil is physically or physically dry: ** Class 12. Coniferous formations (forest). * F. Soil and climate favour the development of mesophilous formations: ** Class 13. Mesophytes.
